hey guys, can ne one tell me wuts up wit my engine..its an jdm h22a , everytime i race i reach up to about 120 miles/ph the engine stalls... is it because of my ecu? or my wirings in the engine..not sure if they did a good job when they installed it..thankz

U.K VTEC

It still has the speed limiter in the ECU. All Japanese cars are restricted to 180 kph or 112 mph to us. My car had it when I got it and I had a shop fit an HKS Speed Limit Defencer. This is fitted to the ECU and overrides this problem. This is done from within the ECU but HKS have managed to produce a small module that connects externally into the original ECU wires, making installation relatively straightfoward, enabling the vehicle to reach it's original top speed.

Also, I believe, the Apexi VAFC has the ability to overcome this problem, but I'm not 100% on that. I haven't got a VAFC so this was the next best option.

is gettin a speed limit defencer the only way to fix it? is there any other way?

U.K VTEC

Like I said, the Apexi VAFC is a possibility, but I'm not sure. There may be other ways but I wanted it done properly.
