Twin turbo c5

I have a 03 silverado SS doing a custom turbo kit myself with megasquirt ms1 just to control fueling . Just wondering if I can unplugged the injectors and hook the ms1 up to a separate harness. Just don't want to cut the factory harness. Is this possiable? My other projects don't have a factory harness and just use the squirt I've never put ms1 on anything with factory controls .

What about using the stock PCM?
not sure of the details of your build tho..

^^^^this.

Just run the stock computer. It is much better in my opinion than a MegaSquirt. I actually bought a MegaSquirt a few years ago for a project, and am going to get id of it to purchase a stock computer out of a truck for an older Chevelle.

Mega squirt is easy and simple . That why I like it and I'm not familiar with anything else. Hp tuners works great I had a friend of mine tune my corvette with it and it works good . I just already have the squirt . And would like to tune it myself instead of running to Dallas everytime.

are you replacing the PCM with the MS?
if not, how are you goin to tune the spark and such?

You can tune spark with the ecm like Parish did back in the day

The ecm will control spark and other functions(a/c, trans, spark) and MS will handle the fueling

Yeah just like Parish did. The ms1 will only control fueling . I just didn't know if leaving the injectors unplugged would affect anything. My thought is no but I would like some input.
