I installed a set of fast 85lbs injectors in my LS2 E40 PCM. Fuel rail pressure 58psi, Injectors are fast 85lbs @ 58psi. It seems that the flow rate vs KPA wont go higher than 63.49 when trying to set. Can anyone look at this tune and help out. I am new to this but trying to learn and need to get the car set for injectors so I can get idle with new setup. Any help would be greatly appreciated.

Will be running around 750 RWHP if this helps any.

Got to scale the tune or manipulate the stoich value

The E40 has a hard limit of 63 lb/hr for injector flow rate. It is a hexadecimal thing. It also is hard coded to seek lambda of 1 regardless of the Stoic setting when in closed loop. You will have to scale several tables including Main VE by (50%). You are going to have to do some more research on scaling for injectors. There are threads on the topic in the HPT forum.

I'm using EFI-L so I can't review your tune.

You can also double your stoich and halve the IFR table. It works well and is simple compared to scaling the tune. You need to make sure all the injector data is correct though.
