Default Siemens 60lb Injectors
I picked up a set of Siemens 60lb injectors after maxing out my FAST 36lbers on my 403". From reading it looks like all i need to modify is the IFR table in the tune. Anyone have experiece with these or know what data is needed in the other tables?

Thanks

There are 7 different tables that you should adjust for the specific injector you use. You didn't mention what Operating System you are using, but I've gone ahead and attached a 2001 Corvette tune with 60# Siemens flow values.

Thanks so much! Sent a pm to clarify if this is correct for my 2002 Trans Am.

It will be the same. You're on a Gen 3 PCM as is the 01 Vette.

I don't know where that 60lb injector flow data originated from. I've used it for several cars with 60 lb Deka injectors.

It seems different than the converted Ford stuff. But if it works, then it's all good. VE table looked good in that tune.

Only issue ive been fighting is the car pops and gargles when first flooring it and then it clears up and pulls hard. It goes pig rich when first flooring it.

What is your fuel pressure? If it's stock, the injector data posted is way, way off. Injectors rated at 60lb/hour at 30 PSI do not still flow 60lb/hour at 58 PSI.

The data converted from Ford is in this file. It's different. Try this.

Change Flow Rate, Offset vs., Short Pulse, Min Inj, and Default under Fuel>General to the values seen here.

If you have any issues, take the min fuel mg in transient down to .016 or so. That'll help with those injectors at idle.
