Hi, I have a 1988 350 TPI. A good friend of mine has a good buddy that installs and tunes Megasquirt stand alone systems in modified EFI vehicles. My friend is trying to convince me into getting Megasquirt for my Trans Am. I have a 350 TPI motor with Vortec heads, and LT4 Hot Cam, with 1.6 rollers. SLP headers, bigger runners, 24lb injectors, and a bigger Trottle body. Would it be worth doing this upgrade?
yes, Megasquirt II is fantastic, i have just installed one in my 383 HSR and found addtional ponnies that i didn't managed to get with just Prom Burning, it is very easy to use and You can finetune for free (you just need laptop) everytime You change any part in engine
Glad you're happy with it. I'm probably going to do it. Who did it for you, and what do they charge? Is there any issues with the converter lock up? Do they make a board, or do you have to use a stock ECM as a donor? Are you using a 5 wire O2?
MS uses its own board and housing. There are so many outputs I'm sure it can take care of the TCC.

if you wait a bit, i'm beta testing the new adapter board for the guy who made the tbi adapter board (diyautotune.com). its a direct tpi harness to megasquirtII connection. its pretty sweet and no custom wiring is required. ms2 would definitely kick *** for your application... especially if you score yourself a wideband o2 sensor.

i will ask him... i assume after we get my car running well (hopefully this weekend) it will be considered tested and anytime after that but i can't speak for him.

yes, on diyautotune he has the tbi adapter board for sale
the ms does not do emissions. if its a concern, you will need to install it in a piggyback manner to keep your stock computer running emissions equipment.
the board i have has a circuit setup for controlling the tcc lockup.. due to it not utilizing the vss it requires the 4th gear signal from the transmission and some other paramaters. havn't set it up yet on mine. uses pin 30 on the ms to control the primary fan relay, has relay's on the board to control the fuel pump and ignition. has knock circuit built in.. its freakin sweet
