[DeTomaso] Fuel injection system and brakes question

[Kirby Schrader]

Konrad,

Getting into this late, but for brakes, I’m happy with three cars with Wilwoods.

When EFI comes up, I have lots of scars.
I started out with an old Haltech F9A on my Pantera in 2000.
It was an all throttle position system, sometimes called ‘Alpha N’, and still used a distributor.
The best part was the Weber manifold with the throttle bodies. Individual runners help a lot and that’s where the smoothing of the idle and extra midrange come from. I was learning and it took me awhile, but I got it set up very nicely and it ran great. My lumpy cam idle that I had with the 4bbl went away…
But I didn’t miss it.

The next system I did was for my GT40. It’s an IR system, too.
Mike Trusty recommended an Electromotive TEC3r. This is a system like Michael was talking about.
Crankshaft triggered and uses coils for each plug. Long story here with a defective wiring harness that had me thrashing for three months to find, but the system is running great. I can let the car sit for literally months and switch the key on, hit the start button and it starts. I don’t even have to get in the car an do anything to the throttle. On this setup, I don’t use the big GM style coils. I use an MSD DIS4 and fire, believe it or not, Suzuki motorcycles coils on each plug. This system is running with each injector fired individually. What they call staged injection.

I helped Don Franck install a similar system on his car and after something learning, he got it going just fine.

Then my Haltech bit the dust on the Pantera and I ended up putting an Electromotive TECGT system. It’s cheaper than the TEC3r, which is their current high end system, and won’t run a V8 using staged injection. I call it batch fire. It injects all injectors at the same time. No big deal, honestly.
I’ve switched back and forth on the GT40 and I can’t tell the difference…

I really like both systems. They are expensive, especially when you consider the throttle bodies and manifold.

If you go with a 4bbl type EFI, you will get some advantages for starting. You won’t have to rejet or rebuild your carburetor.
Depending on the intake manifold, it will idle the same.

Yes, as the Space City guys know, I’ve had issues that had me really pissed off, but once I got around some bad wiring, some bad coils (they were used off eBay, me trying to be cheap, and some tuning understanding, I love the systems and wouldn’t go back to a carburetor, much as Tom Upton razzes me about it.

Yes, the race car doesn’t have EFI. It’s a vintage racer. But it’s got the closest, next best thing! Webers!

So what do you want EFI to achieve for you?
What do you think it will do for you?
How much you willing to spend?

That will help you get better advice. 
By the way, lots of people like the FAST systems. The software is easy to use and is supposedly ‘self learning’.
On a stock motor, that would be a definite maybe with a wide band closed loop.
If it’s got a decent cam and heads, I’ll bet you money that the FAST will quickly tell you it can’t get there from here.
Just experience….

FWIW,
Kirby
