Where would it go? 3.8L V6 Fox Body Mustang

Purely as an educational item, I'm interested in knowing this. The above motor is a tbi setup. They usually have no, or very few, canned efi tuning options available to them. Not talking specifically of the Ford, but more in general. Simply put, most people when modding these motors, would swap out to either a multi port setup, or maybe even go back to carb. AFAIK, seemingly the way to provide tunability to a tbi setup is to do something like a megasquirt, before doing which you'd need to reverse-engineer at very least the pulse widths the stock ECU is sending to those couple injectors.

I'm coming at this from Honda-land, and the dpfi setup on the D15 EF Civic. The Honda motor uses some sort of a staged tbi system, where it has a primary injector and a smaller secondary. So to figure out how to drive these would mean you'd have to figure out how/why/when each injector is used, for which I'd think you'd have to scope it.

I've since moved on to a Civic Si, but I still think about how tuning tbi would work from time to time.

That engine runs Ford EEC-IV and isn't a ton you can do with it, BUT, I did read somewhere that a company was making a plug and play megasquirt for the 5L EEC-IV application. I doubt that it'd help here but you never know.

In this particular case you can't swap to multiport EFI or a carb, like you would do if you weren't rules constrained. But for sure you could put a MS on it and tune it up, essentially it becomes an electronic carb much like the Holley carb conversions for muscle cars. And I suspect this engine would respond well and make great power.

WOW 2450 in ITB!!!! I'm in ITB with the 4cyl and i have to be at 2550

It would take a lot of work to make legal weight with a Fox body and it may not even be possible. Not every minimum weight listed for a car by SCCA is makeable.

I wouldn't worry about any V6s in ITB in the near future...
