How to Megasquirt your 3G Hemi
I agree completely with you. I am just argumenitive some times. My appoligize.
Will the ms2 run the fuel side alone?
Yes, it will run the fuel side alone. I cant recommend running fuel and spark on different computers- increases the cost and requires extra work to tune. Now if you started with a carb and swapped to EFI and wanted to keep the spark you already have, that's different.
I'm sure you already know this, but ms3x has a self tune feature in tuner studio. Very easy to work, and Is a very useful tool to dial in the lower cells in your VE table. Also, there is a VE table generator that you input approximate hp and tq numbers and the rpm that happens at, and it generates a VE table for you. It provided me with a fantastic starting point that was very close across the board.
For WOT tuning, it's really quite simple to tune fuel. Log your WOT pull, then view the log and see what percentage your AFT's are away from where you want them to be. Go into your VE table and change the corresponding cell(s) by that percentage, and you should hit your target AFR spot on.
The only part of tuning that your 'on your own' is the timing table. With all the different timing tables that have been posted, it's quite easy to find a good starting spot.
