pk2 on 88 lude trouble

my lude wont rev passed 3500 rpm with a pk2 mugen chipped ecu anyone know wut i need?

Um. What ECU, and are all of the wire harness connectors that should go to the ECU *plugged in* to the ECU. It could also be a fouled EPROM, but I think the problem is that you are using the wrong ECU.

no the guy i bought this from says its for my car i know him really well i dont think he would lie to me. any way it starts up and every thing works correctly just that the engine light turns on and i cant rev passed 3500rpm and it idles at 1200 rpm. i was thinking the mass ariflow sensor or the TP sensor.

Can I see a picture? I have a P72 right here with a blank EPROM that does the same thing using it in conjunction with my H22A - rev limit stops at about 3.5k.

this ecu is supossed to give better fuel air ratio, red line at 7200 rpm, and learn my car. (chipped by mugen)

srry dont have digital camera

i know im getting more fuel i can definately smell more gas from the exhaust

That is strange, because Mugen EPROMs for a p13 (an ECU for the 93-96 VTECs) go up way higher. Stock p13's redline at 7200, maybe that's what he gave you?

no this is for an 88' lude si
