Ok, first, the motor: B18B block P30 (b16a) pistons B16a cylinder head with intake manifold b18a throttle body (swapped out b16 one due to bad TPS) P30 ECU Ok, here is the problem, basically it's running lean (off the gauge) when I am on the throttle until vtec. I did this a few times to make sure it just wasn't something that was only gonna happen once or twice. NO CHECK ENGINE LIGHT If I am gradual on the pedal it doesn't lean out, and at idle it is fine. Could this be a problem with the map sensor? I didn't have any problems with it on the LS head (it is a remote Map sensor on the firewall.) Maybe the map sensor and TPS wires are switched now due to the swap and the new ECU? I doubt it would be the FPR maybe I need a different map sensor because of this ECU? (I am using my old integra map sensor (1993 RS) (or it is a 1993 DX) I can't remember now What could be the problem????
