I am new here and am looking to use MS on my Buick Grand National, if you dont know its a 3.8 turbo, MFI, CIS, i was wondering what i would need for Hardware to run? It is very confusing with all the different operating systems/versions out there to pick from and all the add ons. Has anyone on here run this, or could help me out with what i will need to get me up and running?

Thanks in advance, Dan

Converting a 3.8 GN to Mega Squirt will not be a problem as the MS code is defaulted to GM sensors. The only thing you will have to change to a 3 or 4 bar map sensor, because of the turbo.

It's pretty straightforward. The standard MegaSquirt MAP sensor is a 2.5 bar that's good for up to 21 psi of boost; it can be upgraded for more if necessary. This link on GMDIS covers the basics of ignition control; although the C3I ignition has a different crank trigger, the signals to and from the MS are the same: http://www.megamanual.com/ms2/GM_DIS.htm

Ok guys thanks for the help so far, what i need to know is anyone familiar with what MS sytem i will need to go with on my car, and what tuning software will work best for tuning my boosted car? The guys over at turbo buick are shutting me down on trying to go MS...

A regular MS2 system would be fine. For the software, there's now a couple options, but we've mostly been using TunerStudio for our own projects.
