after modding my ve table my trims were great, i redid the maf table with the availible spreadsheets, after reconnecting the maf my trims went negative pretty hard especially in the lower cells, should i mod the ve table to bring the trims in line or should i change the maf table so it dont effect the trims as much, or did i just do a bad job altogether and this is the result?

I know ive been posting soo many questions lately, and im sorry if this is bothering anyone, but for any ls1 questions this is the place i turn to.

if you unplug the MAF do the trims line back out?

i didnt try it to be honest it was getting late, but the trims were in line before changed the maf frequency back to normal..

if you can unplug the MAF and the trims line back out (might want to reset them then log) then I would say your problem is in the MAF calibration.

Have you tried using the spread sheet available in the stickies?

yeah the spredsheet is what i used to come up with my numbers for the maf, iim going to have to see if removing the maf again corrects the trims, if so i need to adjust the maf table and not the ve table correct?

yes, the problem is maf tuning if the trims line up once its unplugged again.

I disagree with the way most of those maf spreadsheets work. Others disagree but I generally use LTFT vs MAF once its ve tuned to come up with my new maf table. It works out great. My trims as well as customers are between -4 and 0.

I had the exact same problems Ive outlined how I tuned my maf in this link its straight forward and has worked well for me.
