Stock intake and stock map running rich
Posted: Fri Oct 25, 2019 9:27 am
I have a 2016 base 1.5T CVT.
Would like to ask whether a completely stock car run that rich on AFR?
I wouldn't say mine was completely stock as i still have a decat downpipe and frontpipe installed. I just did a return to stock flash and swap my intake back to stock.
Previously i was using K&N typhoon open pod intake and a custom tune peak 22psi boost.
With stock intake and stock map right now, i realised my STFT at idle hover arround NEGATIVE -12% to -16%, and never went close to 0 or positive at all. Even at partial throttle STFT will hover around NEGATIVE -3% to -8%.
My AFR will go as rich as 9~ when WOT while the AFR.CMD is only 10.89 (which i think still rich for a stock map?)
And also with the stock map, i wasn't getting full boost of 16.5psi as advertised by honda. The max i would get is 13 - 14 psi and thats only peak a while after 5000 rpm. Most of the time WOT only getting 11-12 psi.
Is this normal for a stock car?
With the K&N intake and custom tuned 22psi, STFT at idle will peak -10% then slow climb close to 0. However with partial throttle STFT will hover POSITIVE 3% to 7%. (weird). And 0 when WOT.
AFR at WOT is 10.8 , same goes to AFR.CMD (good tuned i guess)
Hope to get some input about stock car.
