Default Making the swap to e85 need help injector flow rate

Ok so I feel ok with doing the swap to e85 I have the injectors already but I have one issue before I jump into it in hp tuners I found a flow rate for the inectors a bought but my cars tune file is injector flow rate VS pressure delta(psi) and the other file is injector flow rate VS manifold vacuum(kpa) is there some kind of conversion chart for this?

You're going to have fun trying to convert those tables along with offset vs volts vs map, short pulse adder, min injector pulse, etc. I'd suggest buying some newer injectors that have data that correlates to the new tables instead of guessing for empty values from the older style tables. That was probably my biggest issue I ever had with my car, using older injectors on a newer PCM.

He had a 07 so all the tables will be the same no conversion

07+ use the e67 PCM. The fueling tables all use the newer table sets (Injector Flowrate vs. Pressure Delta, etc.), I just confirmed on HPTuners. Where if he's trying to use older injectors that are set up in the e40 PCMs then he's going to run in to the same problem I did.
