LT1-TA

Ok.. lets take someone with general knowledge of vehicles. Knows a little more than your average person. But nothing to intense.
I have never tuned a vehicle of any kind before. Not carb or anything. I have never really had to play with wiring harness's before or anyhting (though that is not something im worried about... im very computer adept and love wires.. lol).
How hard would it be to megasquirt my lt1? As of right now it is stock, then turbo (which is when i will probly megasquirt it).
My worry is because of all the things you must fill out and a lot of it I have never heard of (i know af ratios and the spark advance ALRIGHT.. there are a lot of other things that must be done that im totaly blind about)
Do you think if i ordered the complete MSII and relay board I could wire it all up and have it running in a week?
Its the tuning that im afraid of. But i have to learn somehow (seeing how there aint a simulation program to learn on.. lol)
As for the ingnition... im doing this-------
"""""""""""
sure thing, the megasquirt II pcm has an on board ingition driver circuit that can be installed during the assembly. i am just using an old school cylinder 12 volt coil driven off the MSII. Im using an obdII crank sensor (for misfires on an OBDII car), which is a 4x even pulse crank sensor. this is used for rpm input on my MSII in the hall sensor setting. because of the uneven slots in the opti wheel, the opti cannot be used as a trigger input with the MSII, so i retrofitted this crank sensor.
the MS can preform just as well as the stock pcm, so as long as your emissions guy doesnt know its there, it can and will pass emmissions with the proper tune... lucky for me, no emissions where i am.
im goin to make a write up soon on my car domain page on how to install a MS on an LT1 since nobody else has been able to figure it out.
BTW, mine is piggy backed on my stock pcm, the stocker is just running guages and reverse lockout...""""""""""
