PLEASE HELP! afc tuning

[Spdrcr7882]

I have 780 injectors on my car now, When I floor it anywhere below 4k or so all my a/f gauge does is go lean, but if I down shift and get the revs up high and i floor it it goes rich. My settings for high throttle are all pretty much in the -43 area. So I brought the lower rpm numbers to in the -38 area, and it still goes to lean. What am I doin wrong!!!?

well first off, you need a logger. Do not rely on the flashy lights or even a good guage.

Get a logger.

then you can log timing, air flow, actual o2 voltages, and other very useful values.

You should not have bought an safc and big injectors without having a logger.

Also, just an aside, do you have a bigger pump?? The stock one can't keep up to those huge injectors. Hell it cant keep up with stockers.

edit, just reread, sorry late...

anyway, the low settings are for low throttle percentages, no low rpms.

same for high, its high throttle not high rpms.

Low is for idle and cruize, high is for bootfuls and WOT. The throttle points are where you set when it crosses over from low to high.

here are a couple of good links, but YOU NEED A LOGGER to do this and any other tuning.

1st one is from our very own Kyle, good stuff. http://home.comcast.net/~tarryo/kyle/tuning.html

second one is from TMO, the makers of one of the best loggers out there. http://www.vfaq.com/TMO/ this one has lots of useful info.

this 3rd one is for1g cars, but it still has some very good info in it, it will help you understand the basics(and more) of what is going on and why the car does what it does. http://members.rogers.com/mrjackson9/FAQs/SAFC_Tuning.htm

best of luck and I hope it works out for ya.
