Re: Hunting Idle - MAF Issue Maybe?

I calibrated using the Closed Loop method relying on the STFTs + LTFTs and the narrow band oxygen sensors. I had the MAP disabled in the Engine \ Airflow \ Dynamic disable at this RPM setting by lowering it to 100 RPM

my MAF was reading 12% lean so I bumped my entire MAF curve by 10% to enrichen it and keep the smooth slope, now I am in the -1% to -2% range at idle and cruise so it looks great and I am on the safer side ie richer

I will tune the WOT with a wideband AFR gauge later, at this point I just want to take care of the annoying idle RPM fluctuations
