I'm starting to alter the MAF transfer function in PRP for my car. I have made changes and the AFR numbers are coming down closer to where they should be but they fluctuate sometime .5 to 1 AFR count at a specific MAF AD count.
How long should I hold the car at a specific RPM to datalog that RPM? I have been doing about 10-15sec steady loaded on the street.
How close should i get it 14.7? whats acceptable or best practice?
And, what is normal for the AFR while doing loaded part throttle MAF tuning should it hold like a rock at 14.7 at all MAF AD counts? or will it fluctuate like mine is doing while tuning?
Thanks
