Fuel injection warning light

When I bought my TL recently, it came with Koso clocks. Some of the sensors were not wired in, ie... the water temp and oil temp. The bike ran very well, but the "Fuel injection light" stayed on. I assumed this was because it was probably not wired in correctly. I couldn't get the fuel gauge to show there was any fuel in the tank either. I checked the wiring, and it is all correct to these particular sensors. Yesterday I disconnected the 4 pin connector from the tank, and the fuel injector light goers off, and so does the flashing fuel light. (fuel tank full) . Most of the time, the bike starts fine and runs sweet, but sometimes the fuel pump primes but the bike wont fire. I'm not sure if the two problems are linked ?

Ok, I have found half of my answers regarding the fuel level sensors here ; http://www.tlzone.net/forums/help-forum/127900-aftermarket-koso-speedometer-setup.html

The fuel inj light I'm not sure about.

The starting problem, may have something to do with the battery or charging system, as the times it has had trouble starting ,I have then changed the battery off the bike, then it starts and runs fine. I tested the battery after charging, it reads 13.3V ignition off. When the bike is started it reads 14.4V. Next time it wont start, I will test the battery's voltage immediately. Maybe the battery isnt that good or there is some current leakage.

The fuel injection light will not work due to the issue reported by JoE. in Koso speedo thread (quoted below). The Koso instruments cannot decipher the communication code from the TL ECM.

JoE. said:
No CAN on the TL. Just 5 bytes (4 data, 1 checksum) sent at ~7800 baud. No headers/message IDs/message length info.

Look here...

The battery voltages look good. Have you inspected the starter relay connector, and the loom's gang connectors? They have been known to cause intermittent problems. Any sign of melted plastic or over heated/corroded terminals indicates a problem area.

Thx.... Starter relay connections should be ok. The bike turns over no problem, just doesn't fire up every time. I have already repaired one elec connection in a plug going to the kill switch . I will have to keep looking.

Sorry to hijack (but its not a full hijack, because I might be able to solve a problem.)

But Six5, are you telling me I may be able to decode the TL data stream? :devious

Then say, translate it into something the Koso unit COULD read ???

Well, since you seem to get into that sort of tech stuff, it may be worth a shot. Personally, I really don't have a clue in the programming department. Well.... a small clue......but not enough to make it worth my time to investigate.

As it is, I waste waaay too much time on these forums. :laugh

I'm sure if you PM JoE. in the link above he would be happy to fill you in on the details. He is quite the guru in the programming and machine code arena.

No problem. TL-Data looks like this (CH1/CH2):

More info about data conversion can be found here and here.

I don't think there is a Koso that could show data like FI-Error codes and/or TPS adjustment. Using an additional LCD is possible though: TL Data LCD Demo. Hardware is less than 15,- Euros. Different LCD's possible (1x8, 2x8, 1x16, 2x16...).

Wow , just the ticket...

I have built plenty of electronic stuff, but I"m lost with programming and software. Not sure if this could be permanently mounted on my bike (as I have koso clocks) but def worth having as a diagnostic tester to plug in when needed. Well done Joe

Then there's no reason why you couldn't make one. Just need to get an Arduino Nano and a H44780 type LCD.

Arduino IDE is free, LCD display Software is available upon request.

Sure, just find some sort of enclosure for it.

Maybe it might be worth selling my Koso clock and getting a used K1 clock ? seeing it will fit inside.

ebay ; http://www.ebay.com/itm/2004-LCD-Module-blue-characters-white-backlight-HD44780-/380464863342?pt=LH_DefaultDomain_0&hash=item589579186e

Why would you need this LCD thingy if you use a K1 or K2 gauge cluster? The K1/K2 can show all the data if a simple data converter is fitted.

There are cheaper ones available from China. Plus, I would not use a 4x16, it's just too big. I think 1x8 or 2x8 or 1x16 is sufficient.

Plus 2 trimmers and 1 resistor for contrast/backlight adjustment.

Ok I get you.

I dont quite get the resistor thingy to get the TLS fuel gauge to work. This will work with the Koso ?

Joe,

Just bought 3 minis yesterday for final prototyping. I am going to add in a two vacuum sensors and try to have a digital manometer. Also might sniff the coil when I put my coil mod in for a digital tach.

I have an UNO and MEGA right now running protos... :devious

Dudz,

I can probably build you one ( http://23.23.76.195/images/gpi.mp4 ). My GPI proto using a 9x9 LED matrix. I have a nice lcd from nokia and I am going to use that for my custom "gauges". Worst case scenario, I can absolutely help you write the arduino code. Serial communication on the arduino is pretty straightforward. I will write you up something to get you started.

I think we have some fun in store!!!

Not 100% sure but thinking out loud here... there would need to be some lifting done to get the fuel gauge "working". I can think of a way to at least have a marginally accurate gauge. It was my first idea for a digital tach for my Arduino unit. I was going to put an LED inline on the coil signal pulse in a sealed little box with a light sensor attached to the arduino inside. Your logic could at least tell your gauge when you were low and really low (blinking and fully illuminated). Just a thought. You would still need to wire in at minimum the old fuel sensor line to the incandescent bulb that would have been in the dash.

So much info floating about. I need the "less hassle" option. I already have Koso clocks, but the fuel lights don't work neither can I get fault codes. Ideally one unit with everything in would be best without looking like a car dashboard (like standard stuff)
I appreciate all the help here thanks.

Sounds like a plan! The GSXR gauges will look pretty slick. I am going for a grungier retro 90s look. You have a much sexier S than mine and it deserves a classier look.

They never will, unless there is some sort of a gadget that converts from the TL's "2-Thermistor-Type-Fuel-Level-Sensor" to something the Koso understands. Even then, the only info available would be FULL (more or less) RES and EMPTY. Btw., which Koso do you have?

Dudz said:

No way the Koso could display any TL error codes or TPS adjustment. It just does not have the option to show any 'user provided' data.

Dudz said:

The easiest solution would be the GSXR K1/K2 or the K3/K4 gauge cluster. Those have all you need. Plus with some cheap HW (less than 10,- Euros), the mileage can be set to your TL's actual mileage too.

The slickest solution imho is the GSXR K5/K6 gauge cluster:

It has the temp/error/TPS display plus a gear indicator that can be used. However, I do not really recommend this because there is some additional work to be done. The connector is completely different (does not fit the TL harness), Fuel lights need a converter, gear position sensor needs to be connected... For the skilled only.

As said before, I'd suggest the K1/K2. Here's the GSXR gauge clusters compared to the TL g/c:

Koso RX1N GP style ...

I have built my own small CNC machine and controller that mills all grades of aluminum up to 500x300x150mm. I have also built electronic UAV Drones. Its not that I can't modify more complicated stuff, I just haven't got so much time on my hands.

I could use my koso for the normal stuff, and your LCD thingy will do everything the koso wont ?... So I can have the two working together, am I right ?.... Maybe I will do that and do the K1 clocks later on.
