someone explain this 3bar mapsensor thing to me?
Im not sure there is really much in the way of tuning for the lt1 with F/I unless you get a entire standalone EMS.
AS for needing one when trying to tune with the stock pcm with F/I, im not sure. I have not heard of using one. With the lt1 pcm you jsut have to deal with what you have when boosting. The only big downfall is you loose resolution on you fuel table with F/I on the stock PCM.

Basicly the jsut of it. If you are going for big power it will be big money (if you want to make life easier). Big Stuff or Fast XFI is a big recommendation (and very $$$).
With the stock pcm losing resolution, what I mean by that is you lose the ability to "fine tune as you could before. Not toooo big a deal. But that is a downfall.
You can use the stock pcm. But as for needing a map sensor. Im not real educated in that. Best place to ask that is NOT in a ls1 forum. I would suggest asking Bryan at PCMforless. He could get you running the the right direction... or i can ask for you...
He adds fuel for boost throug hte MAF sensor and the PE table as far as i know.

thats what I was looking for. So if I only plan on running MAX of 14(on this motor/ecu) just to get me into the hi 10's...then I should be good?

You have to keep the stock 1-bar sensor.
The words simple, speed density, boost and LT1 do not fit together.

The LT1 PCM will not recognize the 2-3 bar map, so stick with the stock 1 bar. I add the fuel thru the PE tables.
Thanks,

ok not to get off subject, but i have a 94 t/a and just installed a paxton sn-2000 kit on it. My kit came with a superfueler and a 2 bar map sensor that is supposed to replace the stock 1 bar and i have an OBD I computer

this one is classified in "LS1-LS2-LS6-LS7 PERFORMANCE "
Either way there are just a minor few who lurk the forums with BADASS LTx F/I cars. And I guess you found your answer eitherway (since I took the time to read the thread
).Good Luck. I hope your project moves along a little faster than mine.

Your best bet would be to put the paxton on, and buy a cartek FMU and your set. Or go the extra mile and get injectors and a dyno tune.
the superfueler mounts behind the tb and has 3 separate injectors that add fuel. But it only adds fuel for every lb of boost, no boost, no added fuel. And its very tunable.
check out this link and go to the superfueler

I would get rid of that I heard they were pretty problematic...
