Well I would assume if you block the flow of air that can exit, you are choking the engine. So it wouldn't need as much fuel.

If you block the intake limiting air flow in, you dont need as much...

I would assume once your MAFand VE ( if you want to) is tuned you need to start tuning AE and DE. There is a thread not to far from this one that has a link for a "how to tune AE and DE". It will...

I have had it for a few years now. It makes great power N/A with somewhat of a good tune, still trying to get this lm1 to read right in hptuners. I have been slowing trying to put a procharger P1sc-1...

If your dealing with bigger injectors you need to know your fuel pressure and change that in the tune. You can also bump your idle up 100 rpms. Thats all I did with my xp cam in my camaro before MAF...

well idle and part throttle MAF and VE tunes are done (7500 on the MAF and 4K rpms on the VE) . I drove the car today and will drive it alittle tomorrow and scan in close loop to see how everything...

well you can tune your maf in closed loop to get you idle good. Just do it on a cold start, start scanning and based on your command afr you just copy your afr error config. and paste it to the Maf...

well if the maf is pre turbo then it is reading the air the passes of it so it thinks the air is still on its way to the motor but when you let off the blow off valve vents that air to the...

well did you change the injectors?
Do you have a wide band?

I cant seem to get my Command AFR to sit at 14.7 in open loop, when i go back to close loop it sits right at 14.7 but in open loop it bounces between 14.9-15.2 what is going on. Following russ's Open...

Got a 150 amp converter at best buy for 17 dollars because it was opened normally 54 woot now I can start open loop tuning. Thanks Umrjmac for all your help.

So what your saying is that by me maf tuning in closed loop I am getting my correct afr but the car is helping to do it. If i Maf in open loop and get my afr with out the LTFT and STFT help then when...

Thats the thing my config say that I have little to no afr error but the car is having way negative LTFT's. Am i getting a good afr because the car is compensatinng for the richness with the LTFT or...

I am getting some -1's on my MAf(afr error) but still getting -7 to -13 on my LTFT I am even resetting fuel trims after every recalibration of the maf. I then drive for a day then start scanning so...

thank you

When I first installed it. It is a lm-1, so when and how often should I perform a free-air calibration because I only press the calibration button when I first installed it.

So all last year I got all my part throttle and some wot tuning done but when summer hit the tune was way off even though it was the same temp. Well now my MAF table in scanning is always showing...
