Hi Everyone, sorry for the repost, but my previous thread had an issue that wasn't showing the body or allowing replies.
I just got back from a race weekend and decided to have a look at the data collected by my AIM logger. One thing I saw that was kind of interesting was that my TPS never showed higher than 80 percent open. I looked at my grip position sensor and saw several occasions where the grip position was 100 percent open for several seconds, but the TPS only showed 80 percent.
One of my racer buddies suggested it might be an issue with the ECU not being programmed for my Dunlop tires. I went back and analyzed my front vs rear wheel speed and found there's about a 10-15mph delta between front and rear at high speeds. I believe this is due to the shorter profile of the Dunlops compared to the Pirelli's. Could this be messing with the DTC and TPS and causing this issue? Or, is this not even an issue and just expected behavior of the TPS system?
My race mode settings were EBC: 2, ABS: 2, DTC: 3, ENG: 195Hi
There was no DTC intervention during the times I was WFO and the TPS was flatlined at 80 percent so that makes me think it might not be related.
Here are some pics of the output from my data logger:
DTC, TPS, and Grip Position:
Front Wheel Speed, Rear Wheel Speed, TPS, and Grip Position:
Looking back, the TPS was never aligning with Grip position regardless of percent open the grip was.
One final note is I'm also using TuneBoy tune with the linear torque map applied. I know that's going to make the grip and tps not necessarily align, but it shouldn't keep the TPS from going to 100%.
Thoughts?
