I think it's the twist in the driveshaft that caused a lot of problems, we have too much latency that can't be compensated for.

Did you discuss the issue with Motec?

I would think I could use the crank sensor and add a sensor at the trans input to calculate the diff...

Pun intended? I would think that range would vary too much to run a calc between the two, no?

I was just throwing it out there.

I have no idea since I've not set mine up either.

That's why I was asking.

We need to make Rod talk more... :-)

Oh I get it...

We just need him to give up his hard earned data....

We had one of the guys from motec at the track with us for a whole weekend, there may be a workaround, we have yet to find it, you can't mindread the drivers foot. We decided we need a better driveshaft for the best solution, I'm working on that...

You guys have left me behind in the dust. You're on your own from here on in. :-)

I don't really see how middle shaft twist would cause issues with a TC setup. It must be something with how the Motec algorithm is created.
In essense TC should work only by comparing wheel speeds between driven axle and non driven axle and adjust power delivery to get within a defined slip range.

In real life this will be extremely difficult to get done in a good smooth way with a high powered 4 cylinder turbo engine. For an 8 cyl N/A engine with DBW it should ve very easy though as you can just start cutting some of the cylinders alternatively to to reduce power smoothly. Very hard with turbo engine.

I've also been playing with a sophisticated TC setup (2 different manufacturers) and haven't been able to get it run smoothly. So I'm also running without.

With that said I haven't had the need in dry. To me it's a wet thing. Even with 750+ hp traction is good when you got the tires and the aero.

Which engine management are you using?

can't just do this with an ABS type system?

You've achieved the nicest side dump exhaust I've ever seen on one of these cars.

A lot easier to do it that way with a 911 suspension under it.
