Disable MAP decell based on RPM

Post by ol boy »

I've switched my accel enrichment to TPS only due to getting small fluctuations in MAP value while in boost. With the RPM window of full accel at 2000 and all done by 4000 I'd expect no accel enrichment or decell enleanment above 4k. But I get enleanment which will pull 10% fuel and causes PW to come in and out and cause AFR to move about.

Thanks Ryan

Any thoughts on this James? Maybe if MAP greater than Baro and max rpm threshold then decel fuel == 0.

Or have decell fuel only based on TPS when in boost when above the max RPM threshold.
