Tuning Air/Fuel Help 2009 Civic Si

Post by Actionape » Wed Mar 27, 2019 7:38 am

I've taken a stab at trying to tune my high/low fuel tables, as I noticed running the stock tuned basemap that I was running rich at WOT (around 10.5:1)
I've targeted 12.4, and adjusted for that. Is that correct or should I still tune for a little richer?

I haven't messed with cam angles or anything else as it's out of my depth.

You are using a hybrid calibration with AFM enabled, you need to tune the AFM sensor and not the WOT tables. Its a little bit more complicated to tune and takes more time, but it works just fine.

You could just mark the 'Use speed / density tables" under Calibration - Fuel and tune your engine using the MAP sensor only.

Thanks for the heads up, i'll take a look at tuning the AFM sensor then.
If tuning using the MAP sensor to tune the A/F mix, don't you lose accuracy in the fuel gauge, oil service reminders etc?

I believe that was with the old "Race Files" from before. You shouldn't have those issues with a standard basemap from Hondata. Hopefully someone can chime in for sure.

Oh okay cool, I'm adjusting off the stock(Tuned) basemap. After enabling the MAP sensor, do I leave AFM enabled or disable it?

Disable AFM, then you want to check the "map to determine wot" box under closed loop if you haven't already.
