Hello, One question, when I drop the gas pedal, the AFR goes very rich at moment (to 9.0) and after it stabilizes well to my table AFR , I use Crome and I have the IACV disabled

Someone knows why?


THanks

"drop" the gas pedal as in lifting your foot or press down with your foot? (can be taken either way)

pressing down with your foot is tip-in, pull back the value a little.

lifting you foot was dubbed tip-out a while back. Still not resolved in Crome.
you can help it a little by leaning out the highest two columns above 1500RPM, but it will still be there.

tipout is the delay before fuelcut IMHO.

If you have big injectorsthen this is somewhat normal; but it could also be an abnormally high col1 and col2 values.

Are you using a wide band O2 sensor when you are getting the AFR readings. If you are using a narrow band then ignore the readings because they are far from accurate.

Im using a LC1 + XD16

Is when I lift & press my foot, lifting is more noticeable

I have 310cc and I tuned the P30 map via adjuster multiplier (CTRL+F) first, and after with ostrich

I will try adding the 13.000rpm file and decreasing fuel in this file


Thanks

fuel multipliers: throttle tip-in. reduce that number. Since you have bigger injectors than stock you want to decrease the "base" throttle tip in value as it is calibrated for the stock injectors. Stock injector calibrations with bigger injectors = more fuel.
