The OEM sensor is a POS. Obviously working with who I work with, I naturally run the upgraded sensor. To give you some feedback as to why the upgraded sensor is offered, we need to go back a bit to last year.
Three, high level professional racers we sponsor were having issues with the bike detecting shifts in the upper RPMs and upper gears. Once I thawed out locally, I was able to backup their claims as well as adding in my own experiences where some of the more tricky areas of the track I was on where I would have to get from 5th/6th down to 1st the sensor and finding out the sensor could not keep up on the auto blip. So we tried a new, upgraded sensor, sent those prototype kits out to them for testing and it worked leaps better. Things went into mass production and I started stocking them stateside. I then put one on my bike, way better responsiveness and functions 10x better. Absolutely no comparison. This is also without any adjustments to times/etc.
Now when it comes to the kill time, if you're using WRT, don't look at the 200 as "200 msec". That is just the base value the ECU operates at. There is no scalar values in the software so until we do the scaling manually and can differentiate between what the timing difference is between say 200 and 199 is, then you'll have to play with the adjustments. Additionally, as Chiffee noted, the way the ECU works the values are OPPOSITE of what you would think; you need to INCREASE the value to DECREASE the kill time. This is all going to change in the race package that is being worked on now. So when that comes out before race season, you will have a more robust and proper race tools adjustments instead of the raw ECU values you have now in the software. You will have upshift kill times in msec per gear, by RPM and by TPS, upshift sensitivity adjustment, upshift delay, minimum RPM activation. In addition to that you'll have enhancements and additions to the current auto blipper software. Configurable launch control and adjustable pit limiter will also be going in. This is all in addition to the wheelie, corner management and TC stuff being added.
