I am tuning my car with a WB O2. Can someone point me to an ideal AFR map for the Datalogit PFC.

Thanks

Chris,

You're going to want to do a search on this and read the many varied opinions on this... There have been many good posts by experienced tuners like Rice Racing, The Hitman, Crispeed, etc etc on here and you will want to take in alll that advice and then form your own ideas about what you want to do.

On MY car with my LIMITED tuning experience, I tune for around 12.8 from P1-P10 and then under the boost areas for P11-P20 I pretty much have a smooth progression from 11.9 down to 10.8 or so. All the P-values I refer to are the standard PFC mappings. If you run the 3 bar map sensor or someone has re-mapped your P rows, be careful!

If you want to get more fuel economy you can tune P1-P10 for about 14 and be fine. I ran my car for a long time like that... it does get better mileage and smells less, but I found it didn't feel as frisky on throttle tip-in.

This is what I do, but I am a complete newbie compared to those names I mentioned above, so do your homework and decide for yourself.

i don't like to see anything more than a low 11 at wide open throttle.

 

depends on how brave you feel......heh

i tune for a low to mid 11 at WOT and 13.5-14 at idle and cruise

 

I have my cruise tuned for 14 or so and my low boost tuned to 13 and my high boost tuned to 12. I only run 10* advance at max boost though.
