The RMP range looks a little low to me, especially on the start. If it were me I would start in the 3k-4k start and put the end RPM around 11k. From what I remember when I ran a sentry in my car for a couple months with 17.5 boosted, the motors never slowed down opast about 3k-4k at even the slowest points of our 80' straight carpet track. IIRC the ERPM typically topped out around16k.

I'd also drop the ramp to 2. Then if that lasts 8 minutes but you want to try your luck, try lowering your ERPM 500 rpm at a time. Another approach would be to leave your RPMs and just reduce the ramp to 2 and see how that does.

Just in general I find my power fades are usually brought on by over timing the motor.

Yeah...yeah...lol...I've been out of racing for last few years, but trust me I would rather be someones pit mechanic. Racing once a month when you have kids really kills the skill level. I will move to the GT class sooner or later. l just hate to buy another speedo now after spending money on the car I wanted. Our track runs a fixed gear ratio of 5.0, but I guess the Tekin is still too fast.

I went from 203 to 212, anyone notice that they had to gear down with 212? I felt like I lost a bunch of punch and/or torque. Just me?

I found the opposite. More punch with 212.

Ditto, if you had a decent 203/208 profile, it feels like there's a lot more rip with lower motor temperature with 212.

212 dual mode does not use the sensors for calculations. The start and end rpm are still in effect and allow the dual mode sensorless drive timing to slide timing around.

+1, and the throttle percentage thingy makes it even better.

My mistake - ignore my post. Thanks, Randy.

So the rpm ranges are still in effect in dial mode?

Being mainly an onroad guy that switched to off road just for the winter I have to say that my Tekin feels pretty nice. Running in 2wd open class with a 13.5 I was able to keep up with guys running a 8.5 with other speedo's What are they going to do when I actually get my lines down Just like on road every change made using the hotwire could be felt on the track. Mold the speedo to fit your driving style and track conditions. Might have been better off running my 17.5 to help in the infield.

Thank-you. That explains it why the truck is so responsive on the low end lately. I don't believe v203 used the start and stop points of the rpm settings in dual mode. Since I upgraded the truck to the v212 a couple of weeks ago, its been a completely different truck, but a blast to drive....I have a couple of 2nd place finishes, but no wins this fall season yet. Love this truck and the Tekin HP!
