The car will start and then dies almost immediately. I know the car runs because I have another PCM from the previous build with a VE tune that it will at least start and idle (albeit rough) it does run. The computer with the VE tune is locked unfortunately so I cannot read it. The main points of my setup are in my signature. Bosch 80 lb injectors. Thanks in advance.
Did the injectors come with data? You can't just plug in 80lb/hr in the injector flow rate and call it good. The injectors need to have all the data and the flow rate needs to be setup for the fuel pressure you are running and the style of fuel system, be it a return/returnless etc.
Are you running a stock LS1 1 bar map sensor??
Are you going to run a MAF or is it speed density only??
I still have the stock 1 bar LT1 MAP sensor. The tune is for running the MAF. The injectors went on the car a long time ago so any data that came with them is probably long gone.Quote:

You'd need to make sure of that or swap to the LS1 style sensor to always know you have the right data. But if this vehicle is really procharged like your sig says you need a 2 or 3 bar MAP sensor so you can probably log boost and so that you can use the 2 or 3 bar speed density OS upgrade to have boost enrichment and a larger VE table for tuning boost.
Not having injector data is going to make this very hard to tune.
I lied. It has a 2 bar MAP
Then that is your first major problem. 1 bar settings with a 2 bar sensor won't want to start.
The other stuff about the 2 bar OS should still be done.
I have located my old invoice for my injectors. I have an email out to the vendor to send me the data for my exact injectors.Quote:

Once you enter the correct injector data report back and let us know if there is any improvement.Quote:
