First log attatched

Here is my first log after sizing the injectors. I used the Log Ananlyzer and my load is 30? I am confused here. The first 3 columns are from my WB logger thats why the RPMs are off a little. I also hit fuelcut at line 29, it leans out and the RPMs jump and then come back down. I know its not a glitch because I felt it also.

I used the airflow/rpm*852 formula on you log and your load maxed out @ 243. Whatever formula you used for your load did not work. So do it manually. I suspect you did not log all the variables needed to get MJ load calculator to work.

nj1226, I used your formula compared to aktivematrix' load calculator, the load differs... know which is more accurate?

It depends if your car sees more than 1604 airflow number or not. Mine does not and the formula works for me. Your car may differ.

Seems I hit 1603.95 airflow @ 7000rpm ...... both formulas show me in the 180 load cell after 6500rpm anyway....

Calculating load from IPW, AFRMAP, and inj latency is pretty accurate. I compared it with the MUT load output (which clips at 160), and the calc load matches the MUT load output nicely up to 160 (off by no more than 5). Seems fair to assume that the calc value is accurate beyond 160. It helps to put IPW, AFRMAP, and battery V one after the other in that order in EvoScan so that there is a minimal time lag between the these values which are required to calc load.
