Sorry guys I have to step in here.............

we have tested at length over here (with an actually quite good driver(not me lol))

Irgo you will never be able to test the RPM of the motor without a machine to actually measure RPM's now we went old school and pulled out the old Shinwa motor dresser (antique) gave the dresser its' own power supply and tested up the motors, boost DOES step in where it is supposed to do but there are other parameters to take into consideration....namely GEARING we use 13.5T HW motors and gear them on the car at a FDR of between 7 and 7.5:1 on largeish indoor tracks, the boost needs to come in early (1000) and the ramp to be between 500 and 650, this gives masses of punch in the technical parts and then the turbo is useful for what is actually required (that bit 1/2 way down the straight).

Anyway back to the dresser.........we ran tests with no Boost (Justock) and recorded the results, very smooth rev band obviously ramping quite slowly..... we then ran some runs with varying levels of boost UPTO 30 degrees with no Turbo, so as not to blow the sensor board on the motor. We ran differing Start points and from what our antique dial was telling us (with digital timer) was that there was a noticable difference in the 'quickness' of the accelleration in the motor dependent on the start point for example at 10k RPM start motor was linear and similar in performance to the Justock settings (about 1/3 throttle) ( Unloaded) we heard the familiar 'tinking' noise as the timing switched in and the reading was about 10,200RPM (allowing for variance in the meter this is acceptable) same experiment run with the start point at 5000 same occurance but the reading was around 4900. this seems to point to the Boost start point being fairly correct (this was on my original well used XS ESC BTW)

We tried to do readings for the ramping of the boost but couldn't measure acurately enough without some really high end equipment which I am hoping to get hold of the use of from my Universities Electrical Engineering Department ( Actually hoping to get one of the Undergrads to do the tests for me)

But so far the results we have had seem to point to the Boost entry number being fairly accurate so far.......

BUT !!!!

Ran the same tests with same equipment on my old EXRUN 120 SD and we were unable to get the numbers to match was fluctuating quite badly, not sure if this is down to the age of my ESC or whether the uprated FETS in the newer ESC's really do make a difference with the massive boosts we are putting through them....but thats a game for another day.

back to gearing......... When we add timing ALL we are doing is trading Torque for Revs, so guys you need to make most use of those revs and gear it much higher than the 6's etc of the 518 FW closer to 7/7.5 etc just watch the temps as the motor can't be let over rev itself because that will generate heat just as badly as over gearing it.

To Irgo, I have the feeling this is just another method to get your own way with an RPM logger the SP guys have made it clear to you as have HW guys it isn't gonna happen in the near future as there isn't really a need for it as every race, nay every lap is different in a race meeting so the log will not help unless you are running exactly the same lines each lap etc, I doubt Spashett in his heyday even managed THAT feat
