A/F Tuning help
Posted: Thu Jul 14, 2011 11:09 pm
I just did 3 datalog runs to tune the A/F ratio on my DC5 ITR. My mods are AEM CAI, DCRH, Custom 2.5" Apex'i exhaust and K-pro.
After the first run I changed the values in the tables as instructed in the guides available on CRSX (Wessiah’s & Sik LiL pLaYa’s) and went for the 2nd run. I did the same after the 2nd run and went on for the 3rd run.
On the 3rd run I really felt a difference in the response of the car. When I came back to check on the data log, the graph for the 3rd run was really weird. The A/F curve wasn't as smooth as the 2nd run. Also I noticed that on the 1st and 2nd run, it barely had knocks and on the 3rd one 6 knocks were recorded. Can somebody check them and tell if I am doing something wrong.
I am running on the stock ITR cal that comes with K-pro with 95 octane pump gas.
Many thanks
