Hi,
Looking to improve my own car (stock C6 ZR1), I've built several histograms in order to calibrate the MAF and notice a huge difference in the errors reported between the "old" method and the "new" methods (see smokeshow's and cringer's topics) doing MAF and VVE in the same time.
I've checked the maths formulas at several times and hope - as a noob - there's no mistake.
Any ideas or suggestions ?
The "old" method: errors are not very important (in my view...) and positive
The "new" methods. I know they differ between them but the errors are very important and negative !
Thanks !
