Yeah Pat, returnless systems need to be scaled. Just like your IFR table. At 58psi these inj flow 72.3, so scale from there IMO.Originally Posted by SJSchafer
Here is my take on this.
1) Since no one has nailed these inj settings down yet, there is no "right or wrong" as long as the end result is what you want.
2) If your VE was great before the swap, then you shouldn't necessarily need to mess with your VE after the swap (that much) If you enjoy tuning and messing with shit, try other routes.
3) Being returnless, you can log what vacuum kpa you are at in decel and decrease the backside of the inj offset table to accomplish a more lean decel. Yes, it's cheating, but until someone posts a step by step for the way you really tune these guys, I am game for whatever works. (I don't do this, but I have tried it to experiment, worked fine besides they "gray area" between no throttle and throttle)
as redhardsupra knows justin, he's been working on calcs to get the number right, I believe for a whle he was sold (thru calcs) that somewhere in the neighborhood of .53 ( maybe a touch less) was working the best for the offset somewhere near the 13.5 volt row.
I use .48 @ 14volts, .53 @ 13.5volts, .56 @ 13.0volts (I am a return system). I wiped out my pulse adder as well. Yeah I know , I was just experimenting. I actually never finished tuning mine, I had everything working great besides a rich idle (I am dead set against fixing it with the VE) but I have to get thru emissions so I am back in closed loop for now. Which btw, 14.68 all the time now. LMAO, just -10% Idle trims, lol.
