Another fuel injection question

[SST55]

Na$car doesn't allow computers. FI requires a computer to read info from various sensors and then regulates the fuel delivery by using that info.

I can't think of a system that doesn't use a computer or electric fuel pump, which is another no-no, except for the early mechanical Rochester units on Vette's in the 50's.

So computers and electric pumps,,how long before someone finds a way to hide traction control?

About 60% of door cars run this setup nwadays.

It's actually very simple. Belt driven fuel pump, a throttle body, and a pill (see: jet). The only thing about it, is that like a nitro car, you shut the engine off with the fuel lever, not the ignition. If you cut ignition, it can start dieseling, because if the pump is rotating, it's still dumping fuel in the engine.

In most cases, the Rons system is alchohol, which contains it's own oxygen. So the engine will actually keep running/semi-dieseling even with the throttle blades completely closed. Thus, fuel flow is only way to shut the engine off.

They'll have to make it wi-fi. NASCAR knows the tale-tale signs of the TC units. However, many of our local modifieds have run TC even though it's illegal. I've seen a couple of sites that sell the units.

NASCAR will just make teams use a standard, NASCAR supplied (with a SMALL markup!) ECU to control the fuel injection. This is pretty standard operating procedure across the other racing series.

Or it will be random issue, mounted on the same plate as the coils and MSD boxes.

I'm assuming ECU because of the need to replace the restrictor plate.

Now that would be a good point. Have slightly smaller opening times with a 5mm (3/16") smaller throttle body. Less fuel and less air, and still keeping stoich.
