Trying to get a head start. This is actually in a circle track race truck that I am prototyping for our racing series. I have done plenty of programming, and have been a drivability technician for years, but as far as tuning...not so much.
This is designed to be a next generation powerplant. Our rules limit us to 375HP/375TQ at the rear wheels....for the prototype it's an LQ4 out of an 05 Express van. The only modification to stock is a Summit 8707 cam and long tube race headers. No TBSS allowed, stock throttle body. We mandate cable throttle bodies for safety reasons.
The fuel system is just a sender with a Bosch pump in the fuel cell to a Corvette filter/regulator, finished off by a set of mandated stock 8.1L injectors. This is a manual transmission application. It will run on pump gas...not race gas.
Regardless of it's a carbureted 355 or this LS,
we keep them legal with a Dyno so this will go across the Dyno for final tuning.
Right now it still has the stock van tune in it and the stock injectors. It starts and runs. Obviously if I try to pull it now...I'll be out of injector pretty much immediately under high load. The reason I haven't installed the 8.1 injectors yet....it because from what I have seen....it won't even start with them without a tune. My MPVI is on a UPS truck en route. Looking for a baseline file that will at least get me started (literally) so I can get a head start on it and spend less time on the Dyno fiddling and focus on fueling/timing/HP. The cam is similar to a Truck Norris. As I am sure this isn't a rare combo...anyone have a file to get me started? TIA.
