Finished 2nd to a Prelude with a 2.2 VTEC. Beat me by 9 hp. He had I/E I had I/E/Pulley.

Does anyone know how to defeat our traction control. I had some horrible 1/4 runs on the dyno due to the 2nd cams not engaging in 1st gear. I had to short shift it at 6700rpms to 2nd gear which puts me way out of the VVTLi range. The computer thought I was spinning first gear since I got through first so fast on the dyno. Anyone defeated this yet?

Got 149 on a portable Mustang Dyno. The operator said they are usually about 15% off what standard dynos that you find in a shop. So that would put me in at about 172-173 at the wheels on a standard unit. The Lude got a 158 for his best run.

Traction control limits us to the first cam in first gear if the ECu thinks we are spinning the tires which it thought I was doing since I went through first gear so fast. It completely screwed up my attempt at 1st place in the 1/4 mile competition.

I wanted it to go to the second cam at 6k but it wouldn't do it. The rollers on the dyno didn't provide enough resistance making the ECU think I was spinning through first. Thus I would have been able to keep in lift by powershifting 2nd and got a more realistic 1/4 time. Wasn't a big deal but would be nice to know if I get on one of these at another show.

That's for a normal dyno horsepower run. They had a program setup for 1/4 mile runs where you go from a dead stop and rip through the gears.
