So I get in playing around with the tuning software and I notice several things that just don't seam correct. Now first and foremost I am not a tuner. I'm an old school carb and blower guy but I do understand the principles involved.
Things I noticed;
ETC area scaler number are far below what they should be for a 102 mm throttle body
Manifold volume under dynamic airflow seams untouched from stock settings.
General engine>cylinder volume is not changed.
VVE tables are untouched
Base timing tables are strange with 40 degrees timing down low.
Seems to me that the tuner just bumped up the MAF tables and minimum idle air numbers and called it a day. During logging the fuel trims are all over the place. I was told this is a "MAF" tune but not sure why someone would do that.
I could be completely wrong about the entire thing
Anywho...if some of you experts have a few minute to look it over and give pointers.
