The throttle body is different as is the distributer but everything else is the same..

When I was using the stock 5.7 cal I ran a performer cam, with 202 heads and cyclone ar headers with dual exhaust.. Had to turn up the idle to about 700 but it ran fine after that.. Also a PLUG for Steve at TTS: He sells a package you might want.. Don't have his number but check the archives..

Stoney" Date: Sun, 6 Jul 1997 10:34:46 -0700 (PDT) Subject: Electromotive tec 2 unit fs Hi all, I've got a tec 2 unit for sale. It is from a Ducati FI project; one I never succeeded with because of problems unrelated to the TEC unit. It is a custom unit set up for a 90 degree V2 or 4.I have the super blend software that allows one to blend in tps and map values for smoother off idle performance. Anybody have a project that could use this?

It uses a map sensor and a pickup from the -ve of the coil to control only the fuel. It has 6 pots that set the on time for the injectors over the rev range. I want to put a MSD ignition module in but I think that this will cause the efi ecm to freak out? Am I right in thinking this?

They do act a little snooty at times but you have to just understand how to deal with that type of person. Comes from being an engineer in a Union plant. I learn a lot of finess there.

The system is demonstrably effetective, however, making the most attractive vehicle for auto theft reliant on the measure of control retained by the operator changes the nature of the crime from an anonymous theft to a confrontational robbery. If they want your wheels, and the only way to get them is to poke you in the eye with a '45, guess what's going to get poked. Me, I'd give up the keys. I will provide work arounds for the anti-theft stuff if asked, but don't expect to be able to rip off a car with it. A) Anyone stupid enough to try to boost a equipped car is unlikely to know what a work-around is, and (B) it takes too long, and (C) if you're a car thief, go get it from a dealership, they are about as dumb as you are.
