best e38 os for turbo 4.8 flexfuel
im looking for the best e38 os(year model) as a starting point
im building a ly2 4.8 out of a 09 van (i have the 09 van ecm,harness gas pedal etc) also running a t42 with a 4l80e trans with a single turbo @ 15-20 psi
i am planning on using a fuel composition sensor and wiring it into the e38 so i can run anything from 92 octane gas to straight e85 (or a mix)and the ecm will adapt to it
have 84.2 lb injectors (e-85 compatible)
i would like to run a 2.5 bar custom e38 o/s
preferably something that the 2.5 bar is available for and preferably without the 63.5 lb/hr limit?
i have no problem rewiring the harness for a different e38 (assuming gm swapped wires around at all )
i have a tech 2 /sps subscription so flashing to a different vin is not a problem
so what is the best base file (year model) to start with?
also does anybody have a e38 2.5 bar file i can look at? i searched the tune repository but couldn't find anything
thanks and sorry for all the questions this is my first gen 4 motor project
