If the logged data is different but the curve is staying the same then my guess is for some reason the data isn't updating on the spreadsheet - are you doing a new curve fit and inputting the new new polynomial? It's not totally automatic (I couldn't figure out how to do that except for a straight line).

If you post a link to the graph here I will take a look at it when I get a chance.

If you could inform me on how to do it properly that would be great.

Thank you again for your time.

It is most appreciated.

I logged data, used it in the spreadsheet to arrive at some new final values for my maf curve.

Slapped those in and put my injector offset table back to stock and was going to start tuning from there.

Ok so far so good. So I go for another data logging session and the car is much richer than before. No biggie, I knew I would be off because I changed the offset back to stock.

Well here is the kicker. I import my newly logged data into the spreadsheet and it kicks out the exact same maf curve <img border="0" alt="[Banging Head]" title="" src="graemlins/gr_banghead.gif" />

Why would completely different logged data produce the same output? I mean it's way different data. Before I had alot of + ltrims varying from 3-12%, now my ltrims are mostly negative averaging around 10-13% yet I get the same curve?

Is it feasible thats this is telling me hey buddy the curve is right, go look elsewhere to get ltrims back in line???

Any help/insight you can provide would be most appreciated.

Thank you.
