i recently swap a b16a2 into my EF sedan. after everything done, the car sounds like it has launch control at 1000-2000rpm range. spark plugs, distributor, etc has been check and everything is fine. the only thing i didn't check is the ECU because i do not know how to. it is almost impossible to be driven slowly. ECU is from an EG8 modified to suit the car. at other rpm, the car runs perfectly. need advice and suggestions to solve this problem. any help is very much appreciated.

 

ur running it obd1?

check timing

 

converted to obd2 already.. i suspect its the ECU being faulty. coz when i plug in a friend's to run a test, it's fine.. if it is the ECU, what is wrong? tuning? components? i'm a beginner builder and i suck at electronics stuff..

 

get the right ecu p2t iirc

 

the ecu i'm testing with is the same type as mine. at this moment, we're trying to figure out what's wrong.

 

I think you answered your own question if your friends ecu runs your car fine then there is something rong with your ecu. So get new one

 

maybe. coz posted this topic while doing some test. maybe would get a direct answer. should i get the ECU repaired or get a new one?

 

I would get the right ecu for the motor

 

thats what i fuc ken said

 

id get the right ECU for the car.

 

Your friend's ecu works and yours does not= get the same ecu as your friends since that worked.

 

ok.. i got a p30 ecu for the car. ran fine for two day and the same problem happens again. what else could it be?

 

did u check timing

 

ouw.. haven't thought of that.. but i went for a dyno session and realize that there is too much fuel on low rpm range.. could that cause this problem?
