Ecu problem

Just swapped my revo stage 2 ecu over with a member on here for his standard one and he's broke down on the way home, the first time he said a boost pipe had come off which he said he fixed now the second time he said the car starts but wont rev at all ?

he's being towed back here and im going to put it on vagcom anyone got any idea's on what it might be or things to check when he gets here ?

If a boost pipe came off then Im guessing hes been trying out his new power ?

I would check the rest of the pipes , or do you already know for certain that its an ecu problem ?

ecu was fine on my car wouldnt have sold it otherwise

thats all i can think of is a pipe has come off just abit strange that he has no throttle just wondering if a blown or split pipe would cause the throttle not to work

when i installed his ecu on my car it had about 10 faults stored, was abit skocked when i see it as i have never seen so many faults on one page

ill scan his car when he gets here and post the results

Just thought actually, when he says it wont rev how much does he mean, a little or not at all?

just phoned him he said it doesnt rev at all, idles fine but no throttle responce

ok fault codes

18048 - internal contr.module (EEPROM ERROR)
P1640 - 35-00 - -
18042 - Accelerator Position sensor 2 (g185) signal too high
p1634 - 35-00
18039 - accelerator position sensor (g79) signal too high
p1631 - 35 -00
17526 - oxygen (lambda) sensor heating b1 s2 open circuit
p1118 - 35-00

im going to try the adaption process again then ill give the old ecu a shot

If the ecu was at fault tho it would have done the same on your car.

Seems to me the guy had intermittant faults already which have not gone properly

Regular scans with vagcom is highly recommended and would have saw off the faults so this wouldnt have happened

right swapped the ecu's over and its doing it on mine no throttle, car was fine when it left so its something to do with the ecu any idea's whats happened ?

it was raining before we swapped them could water in the ecu be the problem

just in the middle of opening it up
