924S Hesitation on Track

[txhokie4life]

Got a 924S track car.

I'm getting hesitations at about 5200 RPM in third gear.

If I fight through the hesitations and get about 5400 RPM or so -- it smooths back out and pulls strong to redline.

Doesn't matter whether its a right or left hand turn exit.

The track I was on I don't know that I was able to get to 5200 in 4th gear and if I did -- I was busy trying to keep the car on the track

so didn't specifically notice :-)

We've got an issue of not being able to goto 3rd to 2nd (another item to work on but I think I know what that is),

so I haven't "checked" 2nd gear at 5200 rpm. I suspect same result.

Got a race coming up in a couple weeks -- would like to figure this one out before hand.

BTW, just replaced the battery -- I was getting power drop outs before that -- they appear to be gone

just left with some hesitations.

thanks for you help,

Mike

Check the out put of the crankshaft engine speed sensor when hot at high RPM using a lab scope or if they are original unit just replace them.
