S-AFC help Please !!!

[luvmygst]

I should have posted this in another forum but its a newb question. I have a afc with no instructions. I understand the hi settings but what are the low settings for and can some one give me a ballpark of where to start. the car is a 95 gst 650cc injectors and a fpgreen. THe main problem is the car dies like the bov was vented(its not) I would be ever so grateful if some one could give me a base line of settings to start tuning with. lo/hi is set at 30/80 and the a/f ration is great under boost and crusing(with a wideband) on the Hi I started with 33%correction, but the lo I have no clue. Thanks for any help.

EDIT: THe computer has a TMO stage 3 chip in it too, does that affect anything?

Thanks for the try but the first link will not open for me.

Is the TMO chip compensating for the Injectors?

If not -25 for the highs is a safe place to start. As for the lows only your logger can tell you for sure.

 

[luvmygst]

No the tmo is not compensating. How do you set the low side by watching the o2 voltage?

Keep in mind this guide was written with 1G's in mind. For 2G's, you'll just need to focus on your STFT's and get them as close to 0% as possible when it comes to partial throttle operation.

Just a hint...Try the Tech/DIY section of this site Under Tuning...

im pretty sure that you can send your chip back to jeff.o and he sends you a new one compensating for only like $20
you would still need to adjust your safc but it will be a lot closer
