throttle body closing while wot
Posted: Mon Mar 09, 2015 7:10 am
hi guys, im having this problem with one of my customer's car.
It"s a fd2r with forged internals, cams and afew plug and play mod ie headers, air filter and exhaust.
The car was dynoed afew year ago without any problem and the rev cut was set to 9500rpm.
After afew years of usage then the problem suddenly appear.
The car drives fine on the road but it just wont rev pass 9000rpm anymore.
It will throw codes and the car will stall with no response to the throttle pedal.
i've done everything i could think of that is related to the problem but still the problem persists.
things ive done :
1) changed the throttle body.
2) changed the throttle pedal unit
3) changed the alternator ( been reading that this problem is due to low voltage)
4) add more grounding
5) changed the ecu and different flashpro unit
6) check and recheck the wiring
ive attached a datalog file to explain the situation.
any kind of help would be appreciated.
many thanks in advance
