25hp available sensors?

[timf1981]

Thanks Moonlighter . i now see the post about the sds.
will i then be able to use my Lowrance elite 7ti to see all the data?
or do i need a sims gauge?
Thanks...
does sds stand for anything?

[Moonlighter]

This is the adapter cable you need:

Suzuki SIMS Adapter to SDS 990C0-88136

SDS = Suzuki Diagnostic System. Its the plug where the mechanic plugs their laptop into the engine to check codes, test things etc using the diagnostic software.

Yes once its all connected up, and the engine key is on, the data will display on your Lowrance screen. No need for extra gauges, everything sent from the engine will display on the Lowrance.

If I understand you correctly, I don't think your connection is going to work. I have a DF25A motor, and I also started by connecting the Engine Interface Cable to the connector that goes to the motor lights. Instead, you need to connect to the "Diagnostic Port", which I think is the other connector you found. I described my efforts a year ago in this post:

http://www.suzukioutboardforum.com/s...html#post18631

And if you'll read the next few posts in that thread, I posted some photos of my eventual working connection.

Some Success .
But my wire colors did not match up ..
This is from moonlighters article....

Pin placement: place the pins to achieve the following result:

Engine side (SDS plug) ------- to interface cable side
Gray/red ---------------------------- single red
Orange/yellow ------- --------------white
Black -------------------- -------------black
--------------------------------------------------------------------------------------

on my motor , this is what i found and hooded up

Engine side SDS plug------interface cable

All Gray------------------i ran to Red
Yellow/Red---------------i ran to White
Black --------------------i ran to double black wires
Yellow (did not use)----one Blue wire and a Red wire

My results--- I had SOG, RPM, Fuel efficiency think running hours
I Did not have Trim (i really want to get this to work)

In your pictures it looks like you only hooked up two wires?????

Do you get a trim readings?
any thoughts?
Thanks...

Sorry for my silence. I've been working on my trailer after a bearing disintegrated last weekend on a 4-hr drive home...

My motor has 4 wires on the motor/SDS side, and there are 3 wires in the adapter cable. I had forgotten about having to buy the adapter cable. Now I remember what a painful experience that was, after spending the $$ on all the other bits, and learning there was another $75 to go. ;^(

My motor does not have power trim, so I don't have any trim connection on SMIS.

As described in the thread I referenced, when I first got everything talking, I found that my fuel-related info was grossly incorrect. I tried to fix it by using the calibration functions in the SMIS display, but there wasn't enough correction available. So I upgraded the f/w in my Engine Interface Cable, and everything has worked fine since.

Today I had an opportunity to take a clearer photo of my engine connection, which I attach here. But I don't think it's possible to take a single photo that shows all the individual wires on both sides of the connector. I can write down the connections/colors if you like, but I didn't change or really pay attention to any of it. I just bought the specified cables and plugged them together. I expect you should be able to do the same. I did later buy some of the connectors, because I friend who also bought a DF25A (he did get PTT), but he doesn't really care enough about the engine data to buy a display or the rest of the kit. If you are in the US, I will be happy to sell you a pair of the connectors so you could build your own cable. But it shouldn't be necessary...

[Moonlighter]

If you have engine data then the wiring is probably OK.

Its all or nothing with engine data. So the data wire connection must be correct. You really only need 2 wires connected - data, and power + wire. Check the + wire with voltmeter or test light. Leave the other 2 disconnected.

Re fuel flow data, can you confirm flow at idle, once the engine is warmed up?

You could try connecting te 2 pin plugs (one on the front of engine with the trim plug on interface) it shouldnt be necessary, but perhaps might be on the 25.

The fuel needle stays at 8gmp at all times. the gauge is lit up like the alternator and rpm gauges. two gauges are not lit up.

for trying out the trim wires.what should i look for (voltages or grounds), for taking a best guess .
I know its 50 50 , what are the chances of frying something?
If i guess wrong, or they are not trim wires? do you have any educated thoughts.
?
Thanks for all the help. i had never herd of nmea one month ago. its like learning a new languages.

Ok, you need to slow down and take a breath.

The whole network thing sounds complex but its really quite simple.

The engine sends data from its ecu (computer) to the network. The network itself is really just a bunch of cables connected to the engine and other devices, each one going into a T piece.

The network has to have its own 12v power source to operate.

Once a device is connected to the network, it can see and communicate with other devices that are connected.

Yours is a simple network - just 2 devices are attached to it - the engine, and the Lowrance Ti. The Ti's job as part of the network is twofold: firstly, to display bits of info the engine sends to it, and secondly, to combine that info with its own info (such as Speed info from its GpS antenna) to calculate and display other useful info such as fuel economy.

So your network has 3 T's - power, engine, and Lowrance attached to them. At each end of the network, the open unused ends of the T's are closed off with a terminating resistor. Unless its set up like that it wont work properly.

The Ti is of course set up with pages that show engine and fuel related data - but remember, the Ti is designed by Lowrance to work with all motors from different manufacturers, so it may include some "gauges" that the Suzuki doesnt use - such as oil pressure. So some gauges will be greyed out.

Now, if you read my article you will see that once everything is connected to the network, there is some initial setting up that MUST be done before the system will work properly.

Did you do that?? The following steps are vital, and must be done before you start using it.

First is the boat setup - The engine key must first be turned on. Network power also on. Then you go into the Lowrance menu, find the network menu/then select the device list, then select the Suzuki device, and then configure it using the drop down fields on that screen. This means you set the engine position as "centre", and set the config as 1 engine/1 fuel tank (if that is what you have). You then also set the tank capacity.

All of this tells the network what it is dealing with. It knows that it is talking to one engine, it knows that for example, 5 gallons is the tank capacity (assuming youve got a 5 gal portable tank) and that there is only 1 tank that the engine draws its fuel from.

It will automatically detect that it is connected to a DF25A and the approx model year so you dont need to change that. Its just the other stuff that it needs to be told so that it can then work properly.

You can see from this that setting fuel tank capacity is critical so the fuel used, fuel remaining etc will be correct.

Did you do all of that?? If not, go back and do it before you do anything else or ask any more questions.

Also, see my next post re trim setup.

Then see what you find. See what differences you find now that it is all set up properly.

Now, I will answer one of your questions. Bear in mind when you respond that I dont have your engine, nor can I see what you are seeing in front of you. You need to explain things fully and clearly. If in any doubt, post a picture up so we can see what you are looking at.

Now, you memtioned trim data. Sorry to be basic, but you do have power trim and tilt factory fitted on this motor, dont you? If its not factory PTT, with the button on the tiller arm, it wont work.

If you do have the PTT option, then on all higher horsepower motors, trim data is sent from the engine via the 4 pin SDS plug that you should now have the 4 pin adapter cable plugged into with the interface cable plugged into (the other end.).

Now, once you have configured the network as I have described above, it should all work. But it will of course only show data on the lowrance when:

1. The Lowrance is turned on; and
2. The network is powered on; and
3. The Suzuki is powered on.

All 3 must be powered on or it wont work.

Now, it is possible that on the smaller motors that trim data might not go thru the main 4 pin connector - that would be a big surprise.

In that case, you stated in an earlier post that you found another unused 2 pin plug near the front of the engine that would plug into the unused 2 pin plug on the interface cable, right? Well, that would likely be the trim plug that an analogue trim gauge would normally be connected to, if you had one.

So that would be the one to try connecting if, and only if, once you have done the configuration process properly, and youve done the trim setup as per my post below this one, and the trim data isnt then showing on the Lowrance.

Now, the next question is about fuel.

Next lesson: fuel levels can be shown on the Lowrance in 2 ways.

Method 1: Remember that earlier I said that you have to set up the system by telling it your fuel tank capacity? Well, as the engine burns fuel, the interface calculates how much has been burnt based on the amount of fuel the engines computer is telling the injectors to pump into the cylinders. Some tricky maths involved in there.

Its very accurate. So it can tell you at any moment how much fuel has been used, and, since it has had the tank capacity set up, it also does some simple maths to tell you how much fuel is left. This is called by some people as a "calculated fuel level"

On my Simrad GO7xse, which shares many features with your Lowrance Ti, there is one gauge that shows the engine temp on the bottom half, and the % of fuel used on the top half. I also have figures for fuel used on one screen. I can also show a figure for fuel remaining if i want to set it up that way.

Method 2: on boats with a electric tank sender unit on their fuel tank, a special adapter cable can convert the electrical signal to a NMEA signal and it can then show the tank fuel level on a fuel gauge on the Lowrances display.

Edit: the bar style fuel tank level gauge only gets data from a tank sender unit as per method 2 above. It cant use the calculated fuel level to display fuel level on this gauge.

Final lesson: fuel flow.
Fuel flow is not usually reported on a needle on a gauge, although the Ti may be different. On my GO7 - no. Only reports flow as a figure - which is more meaningful and accurate than a needle on a gauge anyway.

It is usually reported on the display as a figure and it will only appear when the engine is running, for obvious reasons: "Fuel flow" is measuring how much fuel the engine is consuming at any given moment. In the US, this will be in gph = gallons per hour. At idle speeds, when warmed up, your 25 will be using a tiny amount of fuel. I can only guess, maybe around 0.05 gallons per hour??

So until we know more, that "8 gmp" figure that you tell us appears on a gauge remians a complete mystery.

[Moonlighter]

Also, regarding setting up the trim gauge, there is some configuring to do as well.

It is outlined in the guide/instructions that came with your engine interface cable. Although the instructions are for doing this on a SMIs gauge, doing it on the Lowrance Ti will be very similar.

I suspect this needs to be done before you will get trim data onto your Lowrance trim gauges. There may also be some instructions in your Lowrance manual.

Heres a link to the Engine interface manual in case you dont have it. Page 10 talks about setting trim up.

https://www.brownspoint.com/store/pc...ace_Manual.pdf

The good news is that once youve done this setting up and configuring, its done, and you leave it alone.

The only thing you than have to do is to reset the fuel every time you fill the tank. You do this in the Lowrance menu. Engine key and network powered on. Refuel, set to full. Takes less than a minute to do.

I believe the fuel readings were working. but with my small engine the needle is pegged. the gph scale goes form 0 to 30. my motor is probably always under 1gph so I need a digital display for that. i dont think lowrance has that option. i can see the digital reading under engine data, but it is deep in the menu.
I did find the trim calibrate after checking all the things you mentioned.
(yes, power trim and tilt.) After calibration. readings jump around and don't move with trim up or down . no luck with trim plug after attaching alligator clips to both plugs

On the 7ti . in suzuki engine -device configuration....center- The options are (2007 or older) and up to 2015. so i chose the 2015, but cant choose engine type . Under advanced options (Instance 000)
If i leave this page then come back. It looks like i need to choose year again. It is ether not remembering the year or the page is just showing me the options again.

i see you have a download for interface cable. Mine is Suzuki SUZ-990C0-88149-350 SMIS Engine Interface Cable (V3.5) from International marine.

My 7ti displayed this (Suzuki interface cable is software version 3.5.0-MZ1620C-B1.0.....model 1.0.0 address: 2 s/n 3094 instance 0)

it looks like you have a software update. Which i have downloaded. how would i do the update ?

What are the unconfigure option?

somehwere in the options Lowrance had a (a vessels mmsi number) is this important.

Under engine data. Like i said earlier. The gph was listed as digital. and also the rim is listed as digital. and theose numbers keep jumping all over the place and dont move with trim changes.

My boat does respond quickly to not much change in trim. so i wold like to get this to work if possible. there is a very small range from too low, to too high,
Thanks...

I have added comments in red in your text below.

I believe the fuel readings were working. but with my small engine the needle is pegged. the gph scale goes form 0 to 30. my motor is probably always under 1gph so I need a digital display for that. i dont think lowrance has that option. i can see the digital reading under engine data, but it is deep in the menu.

The Lowrance has fuel flow readings. Change to the instruments page and you will see it on the virtual dashboard. It would have been useful to know that the gph figure you told us was on a separate gauge so there was no confusion.

I did find the trim calibrate after checking all the things you mentioned.

I told you in my previous post that the engine year etc is automatically detected and cant be changed, and I also make that clear in my resource paper. As you have found out, even if you try to change it, it reverts back. LEAVE IT ALONE!! You only need to set the engine location and number of tanks, and tank capacity!

i see you have a download for interface cable. Mine is Suzuki SUZ-990C0-88149-350 SMIS Engine Interface Cable (V3.5) from International marine.

My 7ti displayed this (Suzuki interface cable is software version 3.5.0-MZ1620C-B1.0.....model 1.0.0 address: 2 s/n 3094 instance 0)

V 3.5.0 is the right version for your engine. DO NOT ATTEMPT TO CHANGE IT! It is locked anyway and cannot be changed.

it looks like you have a software update. Which i have downloaded. how would i do the update ?

What are the unconfigure option?

Unconfigure deletes the engine location, number if engines, and tank size details so if you do that you have to reset them again.

Somewhere in the options Lowrance had a (a vessels mmsi number) is this important.

No, it is nothing to do with the engine connection.

Under engine data. Like i said earlier. The gph was listed as digital. and also the rim is listed as digital. and theose numbers keep jumping all over the place and dont move with trim changes.

Gph is typically shown as a figure. It will vary a bit at idle until the engine warms up and then will settle and be fairly steady. Of course, once ypu are underway, it will change rapidly until you are at a steady cruise speed then again, it will settle within a smaller range. But it will still vary a bit due to even small changes in the engine load.

My boat does respond quickly to not much change in trim. so i wold like to get this to work if possible. there is a very small range from too low, to too high,
Thanks...

I cant help further with the trim issue as I havent bothered before to use this feature on my network displays

Can I suggest that you get on the phone to International Marine and seek their assistance. In fact they might be best to talk to about the whole setup, its easier to sort out issues when talking to someone rather than via forum messaging.

Mike, Tyler and their crew are very knowledgeable on this networking stuff.

Good luck getting it sorted.
