My first tune (TM)

**twiSTies** · 02-03-2007, 12:12 PM

Summary:
Protuned with a Typhoon, swapped over to a 65mm APS due to heatsoak. Protune learned around it, but wasn't optimal so I bought ST thanks to WolfPlayer's advice.

Today:
A/F Learned was -6.67 with the APS. I turned on live tuning and tracing. I then played around with + and - in the cells for a little to get a hang of it and this dropped A/F learned to -5.10. Then I decided to play with a percentage according to the Cobb instructions and input .95 into the cells being touched by idle. This dropped my A/F Learned to -1.18. I then saved the corrected map and exited ST since its within the +/- 5 max that Cobb's instructions stated.

Next up will be some part throttle tuning, but the roads aren't in the best shape today due to the weather so that will have to wait. The part throttle that I did do, had the A/F Learned sticking to 2.75, so maybe I'll be ok.
