Equation for Air flow in gm/cyl? Does anyone have an equation to convert MAF airflow in gm/sec to gm/cyl. I'm using ls1 edit which has hi/lo octane table in rpm vs. gm/cyl. EFI live spark advance table is in rpm vs. gm/sec. I tried using the equation Airflow gm/cyl = MAF gm/sec * 15 / RPM, which I found in the EFI live help file. However when I log data the recorded vs. commanded spark adv does not match up. Any ideas?

In EFI Live, the spark tables use grams/cyl and you log that with the GM.DYNCYLAIR_DMA pid. If you want grams/sec, you should just log the GM.DYNAIR pid.

Yeah get the lastest version of the scanner and try again to see if it works. Send Blacky a pm about the upgrade www.efilive.com/forum
