I have another question. I plan on using a 730 or a 749 computer on my project car that has a 1.7 litre 4 banger. I don't know if I should go with one or the other. Which would be better for this application? I originally was going to use the 730 with the ANHT program tailored to my application but that was before I got ahold of the 749 out of an 88 Grand Am with the quad 4.
