Racetronix injector scaling Bought a set of 38lb/hr Racetronix injectors. No matter what value I put in HP Tuners, they stay fat. I've tried the recommended values from HPT, I've tried the calculator RedHardSupra has on his blog, and still FAT. Does anyone know what values I need to put in HPT to make these work? Off the top of my head, the value in cell 1 was 43.9

I think I'm having a similar problem with the same injectors. I can't nail down the tune for nothing. I even had mine flow tested, but that was a waste because New Era only flowed them at 3bar and 80% duty cycle... Which is fine if you just wanna know how far apart they are, but useless for IFR tables.

I'm not even close. At low rpm, the afr jumps around alot (according to my NGK WB) and I'm going way lean up high which is forcing me to put very large numbers in the VE table.
Using the numbers from the flowsheet (approx 40.5 lb/hr @ 3bar and 80% DC) and RedHard's calc my latest IFR table starts at 45.57 and goes up to 50.1. But I've got a crappy maf and bad narrowbands haven't messed with the car in months.
