MAF transfer datalog for Tweecer

tuning the maf transfer requires the kams have had time to stabilize. if you clear them before capturing a log, then it will think your maf transfer is perfect, which wouldn't help at all.

you want to wait as long as you can stand it (drive probably 50 miles under differing conditions --cruising, highway, city) so the kams have the best chance to stabilize before trying to use that info to tune the maf. then take as large a datalog as you can under the same type of varied driving conditions.

there is also the variable of the battery voltage (because the lights or wipers are on or other accessories that draw electricity) which can ripple down to differing kams under otherwise similar situations, so try to minimize the differences in the accessories you are running while letting the kams stabilize. compensating for battery voltage variations comes later with the "injector offset vs. battery voltage" function.

grady knows all about that one (among lots of other things grady knows about) ...

most people clear the kam after entering a new maf transfer, but even if you don't, the adaptive logic of the computer would ripple through to the kams.

sorry for the dissertation, but have you dialed in the injectors yet? usually that is first, then the maf transfer work starts.

i have a program i wrote to help me with this stuff. let me know if you are interested in sending me a log and i can run it for you. it helps dial in injectors and the maf transfer.

do you know my little trick for clearing the cam by loading an a9l tune into one of the tweecer slots?

No I don't, please enlighten me. I've just been unbolting the batter and stepping on the brake pedal for 30 seconds.
