Do any of you use SCT's Extreme Tune software to tweak/modify your computer tune(s)?

With this software you can make changes in the computer tune such as:

tire size
axel ratio
timing
idle speed
A/F adjustments
shift points and pressures
speed limiter
rev limiter

The software is available from SCT at no charge. Take a look at http://www.sctflash.com/downloads.php

No
without the ability to measure A/F and tranny perameters, I have my tuner do that stuff

Al I just got the SCT Tuner from Doug and easily loaded the file. a couple of quick questions

You mentioned that you have many tunes to choose from how can you do that with only 3 available on the tuner? Do you have to send it to Doug each time to put a new one on the tuner?

Regarding the additonal parameters available such as A/F adjustments & Spark are these settings in the tuner an offset from Dougs tune? i.e. Dougs tune would set the A/F ratio at 12:1 (only a guess for discussion) would the parameter in the tuner be in addition or subtration to the 12:1 setting?

Sorry I dont mean to hijack the thread I just have not found this info in any of the forums yet

Thanks in advance

You have to delete tunes from the tuner and add new ones; you can do it with Extreme Tune software.

You can eventually tweat the tunes yourself. But just use them as Douge wrotew them for now.

Good luck .....

Al can you recommend a good article website book etc.. for learning about the tunable parameters and how they interacy?
