I need help - Third Generation F-Body Message Boards

I'm new to making my own proms. And I have a 86mod 305 TPI, but i'm now swapping to a 350 and using my old TPI system with 30lb/hour injectors and a paxton supercharger. I want to make my own prom with the new values for the injectors and the supercharger. But I only have the bin from a performancechip for the 305. Can anyone help me with a binfile for a original 350? So I have something to start with.

EDIT: It has an automatic trans th700R4

i have found the right bin and the right definitionfile, and I have 30lb/hour injectors and I want my new binfile to know this, but in the binfile its given in gal/hour. How do I convert 30lb/hour to gal/hour. I'm from Norway and I'm not familiar with all the US units. Can anyone help me?

Assuming STP 1 gallon of gasoline is 6.25 lbs. So 30 lbs = 4.8 Gallons. 4.8 gal/hour , what definition file are you using that has it in gal/hour?
Also, I'd advise you getting a 1227730 or 1227749 ecm, installing a 2-bar map sensor, repinning the harness, install a resistor then jumper for the knock sensor to work, and running the sy/ty turbo truck code. This will allow your ecm to read boost and atmosphere correctly for a boosted application. It's not very hard to do the conversion. If you decide to do that you would want to install larger injectors and remove the FMU completely. Just giving you my

i found out that 1227165 was the right definitionfile, maybe its not? This file has gal/hour. You mean I should swap the MAF for a MAP sensor? When I used the supercharger on my 305 I had the MAFsensor in front of the supercharger. Is it easy to swap to a MAPsensor? Won't the knocksensor work if I use a MAP? What is sy/ty turbo truck code? and FMU? Thank you for good tips, I'm kind of new to this. There is nobody here where I live in Norway with experience in tuning a car with TPI, so I have to learn everything myself.
