check out my tune please

No timing wont change fueling. more then likely it was changing the injector flow rate. unless the maf is off to begin with.

thanx chris. i read that post. makes sense... still is goofy that flow rate is factory tuned in ascending order. im trying to bum a fuel pressure gauge, to set up my injectors.
ive been reading on maf tuning. and i guess my brain is past capacity because im not absorbing anything lol....

thebeewantsboost,

If you want to return your car to original tune go to the bin repository and search for your model, year and transmission, there you will find a stock file for your car. You only have to copy the differences to the actual file you have, save it with a new name and flash. By the way if you have change your stock intake you have to calibrate the MAF sensor, follow the Russ guide, http://www.hptuners.com/forum/showpo...64&postcount=1 , you will need a wide band sensor for this tune.

i'm starting to think the tune is bone stock except for the fans, and such because i can't imagine a "tuner" leaving a huge dip in a timing graph. and every stock tune for vehicles like mine had different injector flow rates than eachother.
but thanx for the advice.
so do u guys do you're ve without a wideband?

[thebeewantsboost]

no fuel pressure gauge but, i did order an aem uego wideband
now, i'm so confused....
if you are tuning the maf. do u tune ltfts?

[chrisb]

you can tune with ltfts and stfts if you add them together for one cell that will give you a total trim for that cell. but you need good steady state data.

this might help
