Hey guys, it feels good to finally become a contributor. Anyways, I am very interested in this ROM tuning, but know next to nothing about computer chips, how they work, and how to modify them. Basically I would like a question answered about their use to tune.

I have a race car that has a fairly wild N/A engine, and I have ruled out JWT, since I hear about problems with lean air/fuel mixtures when using high overlap cams and the Gen 6 header. I have narrowed it down to having the maps tuned via a Tectom program, and this.

Now for my questions.
With the ROM editor programs, what can be edited? Fuel and timing, knock sensor and rev limit? How easy is this software to use? Could it be tuned by someone who is an expert at tuning, but has not used this program? What would I have to do to have the computer ready to be tuned? Send my ECU to Calum and have a lappy?

Basically what it boils down to is that the tuner wants $750 Canadian (roughly 600US) to add the tectom chip to the stock computer, plus $200 per hour to tune. I realize that I'm going to have to pay for tuning either way, but would this be a cost effective and somewhat simple to use alternative to the tectom option?
