here's a question, my IFR table was constant(not scaled) for 42lb multecII injectors, and I'm returnless, and my truck drove excellent, doesn't that go against what we are saying here?

 

I think that is a Maggie thing for some reason, Bill (Wkdivr)IFR table was the same way. I am not sure why they do that. Moregrip- I am assuming you still have the stock Maggie IFR table correct? Does anyone know why they do that, in a returnless system the Press. drops with boost so the IFR values should be scaled to compensate. I imagine they have to have a reason but why I dont know....

 

yes, magnuson's tune is loaded with a few PE tweaks from the last dyno session/tune. If the numbers are constant on a returnless system can they be compensated for somewhere else(another table)?

 

I dont know, I mean yes but I am not sure where. VE? MAF? Also moregrip, the last IFR table you posted with the #'s for the 60lb's is just like mine. I made mine up using redhardsupra's IFR spreadsheet. As to the Offset table, I imagine Justin was refering to 50% more then the one you posted up earlier not the one that is in it now. My 14V row is somewhere in the high .4X range. Like .47 or something Ill have to look.

 

that last IFR table is the only thing I've changed in the tune so far, trying to get smart fast

 

I hear ya man, Ive been there....

 

next question, why would one change the Short Pulse Adder and Short Pulse Limit tables?......how do these tables come into play when tuning for the 60lb injectors?

 

At varying pulsewidths, the flow of an injector will change. It's not at all linear.

 

sounds like historical data would be the best to apply here......?
