Just got the car back from the honda dealer

They sad that the ECM (uk) is broken, ecu failure the scan told them, so they cant program the "keys"

They think the car will start with the european ECM working(several number is different between the boxes, if that mathers?)

So now im gonne change the whole engine wire harness on friday, and even the fuelrail, all sensors aswell just in case, and see if that make any changes! im taking this stuff from my US engine (f20c2), then i will try with my US ECM

i dont have time waiting for a new euro ECM, thats why im trying this

If the "internal" engine is OK, shouldnt this work then?!





Thanks

Thats the problem i cant get the f20c2 to work with my US ECM, (my keys are programmed for that ECM)

I think its maybe something wrong with the UK harness (or it is just not work with US ECM), but im changing everything just in case tough the engine has been in a crashed car.
it could be a damaged cable or broken sensor somewhere....

I keep you guys posted

That truly sucks. Sorry to tell you so late, but I am using my original wire harness with my F20C. Good luck and I hope you'll be back on the road ASAP.

Now finally the engine run :-)

There could have been a broken cable in the wire harness or it just wasnt fit for US ECM

But my idle is strange, very low about 500 rpm, and i get a cel as soon as i start the engine

I think it is the IAC valve, gonne try changing it today

changing wire harness was a b*tch with the engine in the car

Used a scantool today and got the DTC P0122 = Low voltage in TP Sensor Circuit (tps)

Can this thing make my car idle strange? now my idle is high 1200 rpm

how much voltage must send the TPS?

I have a pro flow TB ( a US Tb bored to 70 mm) on my Euro S2000 and some time the engine seems to stall

Squeezer

sounds like your MAP sensor needs to be whacked (search for map sensor whack). sometimes the MAP sensor gets screwed up and taking it off and hitting it with the rubber/plastic end of a screw driver and putting it back on takes care of it. if your TPS wasn't set correctly, you'd have a high idle, not an occasional stall.

Now the car runs just fine :-)

I replaced the TPS (and throttle house)

/thx for all help
