New to tuning? Step inside

[John Teach]

CHANGE TUNE FROM AUTO TO MANUAL OR VICE VERSA:

1) Get tune from Bin file repository or somewhere. Copy out of someone with same year car as you if you like.
2) Upload file just as though you would any other file.
3) Enjoy you now have a M6/A4 program.

I don't get this, and I'm stuck with an automatic tune, I'm out of credits! Just did 411 swap and accidentally licensed an automatic tune for it, of course no refunds!

How to swap the trans???

I would like to know also.

So when tuning in SD mode, I set the MAF fail to 0HZ to effectively do the same thing as unplugging the MAF, I get that. During the logging process, if the big thing is to not enable PE, why I cant I just set the PE Enable to 105Kpa or higher? Wouldn't that effectively disable PE while tuning, or are there other factors that trigger it? I tried it and it seemed to work after I let it warm up to OT.

You could do that to avoid PE.

The problem is you typically want the extra fuel while at or close to WOT to help keep the cylinders cool, so you don't really want to go that far with it.

DO NOT DISABLE PE...there is no reason to run the risk of running lean. PE is a fixed adder and your error data is based on the difference between commanded AFR and actual WB AFR so the MAF or VE is the element that would need to be modified to correct any fueling deficiencies....

Hello! Can some one explain me please. Why we don`t use summ between LT and ST for correction and take only LT parameter?

[schpenxel]

I prefer using LT+ST personally. Some prefer using LT only. Try them both, see what you get..

I can`t get good results (( I have Hummer H2 LQ4 2003year. When I unplug MAF socket all is good and I get from 0 to -4 use only LT. But I read that I have IAT in my MAF because of that I need to leave it plug. And now I can`t get right corrections. Tried to use LT and ST summ. But If I count From LT Fuel Trim and LT Fuel trim graphs I get one corrections. If I use grpah with math parameters LTFT+STFT I get another corrections ((( What I do wrong?(((

Start your own thread about this and post tune and a log, you will get help much faster.
