MAF Calibration Excel Spreadsheet

Hey all,

A few folks have asked for this to tune the LT1 PCM MAF. I am glad to share it but I have not given a lot of instructions. Give it a bit of time to sink in and ask questions along the way.

Further, if you have ideas to improve it, I would really appreciate it.

Shoot me an email if you want it: irentat@cox.net

Ben, started playing with the sheet, I'll let you know how it works out. You are using the LT BLM's in the data sheets. What I noticed is the PCM takes a while to update them (average in the new settings) after changes. Should I assume the PCM should be reset after each change to make sure the old historical BLM data is cleared and the readings reflect only the latest change. Also guess I need to disable WOT (PE) to get any BLM readings for MAS above 98 GM/SEC, been reading your WOT tuning posts.

You are correct on both counts.

On the BLM's, I massaged the data by throwing out the first few seconds of data in a particular cell because I knew the computer had not had a chance to modify yet.

I hope you can be another set of eyes looking at this stuff. I am the only one that has done this and, believe me, I don't know enough to be thorough on this.
