My Tc250 Is Now A Te310, Ecu Issues

Hi Guys,

I love my tc250 but after knocking the oil line (to the intermediate shaft on the head) and kinking/ damaging it the engine starved of oil and the piston stopped abruptly.

I have now rebuilt it fully with te310 cases, crank, barell and head. I brought a te310 ecu also thinking it would would work. Boy was I wrong!

So now I have the delimber of sorting out the fueling. I have rung a company who remap hear in nz and they couldn't do anything.

Has anyone done this before?
Does anyone have any ideas that wont run the cot of the build up too much higher... I have thought about a power commander ect, but im not the biggest fan of piggy back's.

try your old ecu (if it's compatible) and see if there is a positive change.

The TE ECU software would be looking for O2 sensor feedback, which does not exist on your TC. Your TC doesn't have a clutch switch either, which is a circuit that needs to be closed before the bike will start on a TE ECU. It's difficult to speculate what else the TE ECU would require. The best thing to do would be to have it reflashed as a TC 310. I bet ZipTy could do that.

What year is your TC 250? Is the FI Mikuni or Keihin?

Do you get a spark when kicking the motor over?

Actually, I think it may just be the O2 sensor. Looking at the schematics, The clutch switch just interrupts the relay. It does not tie back to the ECU.

Yea it doesn't have the spark or injector pulse. If you are look at the same diagram as me I found the te has resistors before the Maqs sensor (map, temp ect) and the tc doesn't! I have been wondering about changing the air temp signal with a resitor in the line...
Surely if the o2 sensor didn't exist it would just run in open loop? (as a car or truck would?)

I contacted zip tie before i started and didn't hear back so was guessing he couldn't help.
Its a 2011 with mikuni injection

You can't by an interface kit and change
the mapping can you?

old ecu runs the bike perfectly (half a kick and it started), sorry should have put this in the title. The wiring diagrams are almost the same for the two ecus but not quite. Different terminals for the run circuit and resistors into the maqs sensor on the te.

I believe the Mikuni interface tool is referred to as the iBeat. I have zero experinece with it and could not speak to what it enables you to change.

Zipty answers to calls much better than email. They are very experienced with tuning and performance mods and are willing to talk to Itallian Husky owners, which is rare.

Thanks mate, I have looked into that (got quite excited), then realised that the interface is a 6 pin plug where as the microtech ecu loom (tc250) is only a 4 pin plug. Hoping like crazy ziptie can do something. I have emailed him again and will ring if I don't hear back?
