4.1 iron block question?

[gndriver]

I'm thinking of getting a 4.1 iron block built for my car, but was wondering if you need an ecm made specifically for the 4.1, or FAST system or can the stock 3.8 ecm with a chip designed for the 4.1 be used?

Stock ecm can be used but u might need it modified for low impedence injectors if u go higher then 50lbs injectors. What are your plans?

My remans has done great until now but I'm thinking of building or having someone who knows build me a 4.1 with a te45a, 60 pounds injectors along with the stuff i got in the car now. My goal is to have it as a dailey driver take it to the track a couple times a year but running it on pump gas no alky. I'll run it on c116 if I dont like the results on 93 oct. hoping to get around mid 11 sec car on pump gas. I would think it would be easier with the 4.1.
