very cool Russ.

Under ChumpCar rules would this not be illegal?

Everything has to be OEM to the original make/model vehicle you race. Parts need to be 100% stock

Yeah Rus, vid showing engine running on fumes is impressive.. .or was there a fault in the fuel gauge?

It would be wrong to assume that you need a 100% OEM vehicle to race in Chumps - you can make any modifications, it's just that you would use 'points' and the total number of points you can use before getting penalized is limited.

Also 24HofL is different from Chumps, crazy stuff is more welcomed in 24HofL. For example, check this car - http://forums.24hoursoflemons.com/viewt ... p?id=28587 - rumors are it's well above $15K, but it's epic thus it's OK.

which gauge? There are three clusters there.

Stock gauges does not work - Chrysler bus is still a TODO. BMW and Mazda clusters do not have fuel gauge hooked up

First v8!

Id love to see more on this.

Recently a friend picked up a new engine+trans for his race-car, our problem is that the ECU is probably set for maximum economy, while we're chasing ponies. Doing this on the slimmest budget ever a 'real' performance ECU is leagues out of the question (The cheapest is around 3-5x the price we paid for the engine+trans.

http://rusefi.com/ and http://rusefi.com/forum has more on all this.

If you are going to use an engine in it's stock configuration stock ECU would not be that bad. In order to be sure you are gaining something you are probably looking at a wideband sensor plus controller and maybe even some dyno time, which would probably cost some money.

A week ago this ECU has finally made it's debug at NJMP 24 hours of Lemons race!

Well, not much to report - the ECU has simply performed, hour after hour. The car had some minor mechanical issues but it took the checkered flag on this computer. Now that reliability is proven I need to add some cool features
