AFR at WOT:
AFT cruising:
1st fan Temp:
2nd fan Temp:
Timing:
To work with the AFR do i have to turn off the MAF??? OR something like that, i have read something like that.

How do those of us without HP tuners go about viewing files.....I need to view some as well but do not have a password to log on. I would also like to send someone my files for review to determine if I have any major problems that may help my vehicle but my file is in .jcl format.....however I may be able to save as a .cal but have not tried that yet.
Where can I find some .bin files for viewing??
thanks

Every engine is different, but in our experience most naturally aspirated LSx motors make the best power while keeping spark knock in check at around 12.5-13.0 AFR (EQ Ratio 1.176 - 1.131). To know for sure you need to put the car on the dyno and try some different AFRs, and you also need to verify the actual tailpipe AFR versus commanded AFR). And keep in mind that some engines want a different AFR at a different RPM to make the best torque and HP numbers.
For the fan temps, it depends on what your strategy is. If you're trying to keep the engine as cool as possible, then having the ON temp within 5-8 degrees of the temperature at which the thermostat *opens* (not necessarily its rating) is reasonable, and having the OFF temp 3 degrees cooler then that.
Timing curves can vary wildly depending on the engine, its setup, fuel grade used, elevation, WOT AFR, etc. Generally speaking, at WOT you want to run as little timing as possible, to make the highest amount of power measured at the wheels, with 0-1* spark knock. You need a dyno for this. In the absence of a dyno, you can just tune for 0-1* spark knock, but you won't know if this curve is making the most power.

ok but i wanted to know, how do you work with the MAF table, when i am suppose to disconnect the MAF or what to do. Because i have read that above some rpm the MAF takes place or i dont know hwat. I will be using efilive since that is the program that have the guy from the dyno
