Hello, I have a boosted d16y7. When I bought the car it was running a P2N ecu with a a'pexi SAFC. I recently swapped a y8 intake manifold onto it, but kept the y7 tb and 3 wire Iacv. I then got a socketed p75 ecu and got a basemap chip from phearabletuning. The car won't run now, it starts up but then shortly after, falls on its face. Even under throttle. I'm still getting fuel and spark. Kinda stumped here, need to get this thing running as it is my daily. Any ideas or info would be greatly appreciated. Thanks.

 

do you have a wideband?

 

Yes
