Maft gen 2 Question
on all my logs I have a lean spot during spool up and wanted some ideas on what I should use to try and correct it or richen it up.
its where the red circle is. I have the maft gen 2 and I do have evoscan with the tactrix cable and ecuflash..
This graph shows a more severe lean spot than most of my logs. If this is normal just let me know.

Oh my car has a blow thru set up with a 3 inch gm maf sensor. Dejon uicp and intake pipe. Rmr licp Turbo xs ic hks 272 cams Hks bov fuel pump Turbo xs mbc and 3 inch downpipe and full exhaust with test pipe. and a sun auto hyper force system head studs too.

Also I was wondering if "tip in" meant the time or area before spool up or full boost?
Thanks

you should figure out what RPM/LOAD you're at in that particular spot, and add fuel if its leaning out

Well I have the GEN 2 so let me give it a try.

Do you have auto AF tracking on?
Is your map stock or have you flashed at all?
Can you post the excel version of your log?
