Im using a .bin from a car w/ exactly the same everything except for year. I need to change the injectors from 28 (2002) to 26 (1999). I went to the link in the sticky for calculations. The car is not started yet so I cant get the fuel pressure at idle, can I just put the pressure w/ pumps on to get it started and then check pressure and recalculate it?

would the 3 values be like this for stock 26lb injectors?

Injector Rated Fuel Pressure: 43.5
Your Fuel Rail Pressure: 58
Injector Rated Flow Rate 26


The car has 58psi of fuel pressure w/ the key on but not running. So where do I put those final table values in HPTuners? Can someone point me in the right direction (menuwise) of where to find the refrenced table in the software.

This is all I'm needing to fire the car.
Thanks
Charles

Why don't you download a tune from a stock '99 and copy the IFR table into your '02 tune?

thats what my plan origionally was, but i was wondering if my added fuel pump would increse the pressure or not, thats why i thought i needed that calculator.. i will do that.. thank you sir!

You probably want to do the calculator as the pressure is different. Ask Chris on HPTuners.com

Sorry, just re-read your post. If your still at stock at 58psi, just copy the tables.

Copy and paste this in your IFR table. This is from my buddies stock 99 LS1 file.
