Hey, I installed an AEM fuel rail and Venom fuel injectors. This was on my JDM h22 transplant. I have a rechipped ecu, and the problem is that the car ran worse after the install than before. I pulled the fuse for the ecu after the install and let the puter reset itself. Didn't help. The car is presently back to stock and running fine. Does anybody have any suggestions on anything to make the performance better with the upgrades? Let me know. Thanks.
Are those the only modifications to the engine? An aftermarket rail and injectors is unneccesary unless you have either an intense N/A engine build, or you are running on Forced Induction. On a stock engine (or even one with mild bolt-on's) an aftermarket fuel rail and larger aftermarket injectors will not gain you any power.
I suspect the culprit of your bad running engine is the rechipping (what brand? who did it?) coupled with a high-flow rail and injectors that are probably not in spec with whatever the new chip's fuel maps call for.
the only other bolt ons are headers and cold air intake. The chip was done bya company in Canada. they didn't just rechip, they supplied a remapped ecu. Other than that it is an NA setup.
Since you got the ECU done before the injectors and rail... the new maps that the company created were made to make power with the injectors that were on the car at the time. The maps are probably not adequate for the new injectors.
