logger question

[boostyGST]

On the STFT and LTFT, when it reads %'s, is posative rich and negative %'s lean, or is it the other way around?

If your FT's are above zero, for a 2g, the ECU is adding fuel to compensate for what it believes is a lean condition. Anything below zero and the ECU is removing fuel.

Is there something wrong with your FT's?

well i am in the middle of tuning my car with SAFC2 and datalogger, and i just needed confirmation that was how it worked, @ 1000rpms I am reading 17% on my datalogger @ -15% adjustment on the SAFC2, should I increase or decrease the % on the SAFC2 to put the datalogger back to 0%

Okay if its reading +17 on the data logger you should put the safcII to about -20% and see how that helps also it can take quite some time for the LTFT to change so give it time.
