What about at idle/cruising? If the FC didn't get richer now that the fuel pump has changed then I'd guess that the Toyota ECU hit some programmed limit about how much fuel it thinks it's injecting to prevent an over fueling runaway scenario4CylinderSpecial wrote:Nope.

Re: Stock ECU not richening under boost
No change in idle/cruise. Yeah it's a mystery but I'm glad that i've inadvertently fixed it one way or another. With the only real constant being changed being the fuel pump it seems a bit strange. Map sensor is healthy and TPS works fine. So not sure why else the car would stay lean.mknz wrote:What about at idle/cruising?
