correct, there is no switchpoint if you don'T tick "highspeed timing with switchpoint"

so the switchpoint rpm is functionless -> smoother feeling

switchpoint should be left at 10k though as that's where it should be if sensors would break during a race to be able to continue sensorless

you need to update the speedo yourself but that takes about 1 minute ...

how do you define "telemetry doesn't work"

the motortemp function ofcourse only works if the motor's got a tempsensor in it

all new GM / Graupner motors do have one

Hi Martin!

There is option to get "external" wire with temp sensor from GM?

Sometimes we can't use GM engines because of event rules.



Regards!
m.

ps: whish you good luck at Warsaw/ETS

Thanks for your reply Martin,

My battery reading is between 0.5 and 0.7v - perhaps I am missing something.

I use new style GM motors only, 97305, 97290, perhaps the sensor is faulty

Scrub the last post, all good now..

Tried a bigger track today (100ft straight) with the new software. The dependent timing and powerbandless delivery is a true masterstoke..the car is very, very quick everywhere but controllable in the infield.

Throttle feels incredibly direct. A bit of a shock at first. Needs a bit of adjusting to..

It seemed slow at first because its so smooth..until I realised I was even faster than the SXX stock spec drivers down the straight. Oh dear. Temps were amazing, 63 deg C. No heatsink.

0.5 seconds off my fastest lap from last week..and I haven't really started to play with the gearing, rotor, etc.

I love my 7.2 (still do) but this thing is the next level. Seriously impressed.

Nice to hear that.

Which Fixedtiming value did you use?

BTW, I recommend to use 90 or 100A amplimiter. You won't loose too much punch in the infield but the motor just stays cooler.
And 4kc frequency. Same effect.

Gearing doesn't really matter.

Tried it indoors.

Went from 6.0 to 4.5 and there was nearly no difference. 4.5 was fast in the first 2laps, then the magnet fades and you are no faster than with 6.0, but 6.0 was much nicer to drive as it is more consistant and as you also mentioned more precise on throttle.

I guess Outdoors, 5.0 - 4.0 will be the range to use

I Raced tonight at my local track (16x30metres),

I Ran Martins recommendations (pretty much Mode 9 std) and WOW

!!!!!Serious Horsepower!!!!!

I tested with and without the switching point and I have to agree with Martin thats its seriously smoother without a switch point!!

I wasn't matched on the main-straight and it looked like a full blown modified haha.

Temperatures were about 65 - 70 degrees so about right.

I really question the need for modified motors indoor now

Gearing was 6.3 with the speed passion 10.5

Hi Martin,
I can't read telemetry data either.

Could you please review if my reading data sequence is correct:
- motor test run (motor #97303);
- switch off esc by on/off switch
- unplug power;
- connect usb link to pc;
- run software, fix port;
- receive data;
- plug esc to usb link;
- and I must press reset on the usb link to start data receiving.

After all data are received I have wrong telemetry data. There is not max rpm, amps, also battery voltage is around 0,2V

Could you please advice?

Thanks,

Robert

For 10.5 motor 12.3mm magnet 97290, indoors

I found that no timing or very little on the bottom end was best with FW7.2 and gearing at 6.44 (a good balance of punch and no fade)

so with FW11.1 I used 0 powercurve and fixed timing 25, amplimit 130. This worked well for the whole 5 minutes

Next week will try 97305 big magnet. I always preferred the feeling this motor has but have had problems with fading. It needs to be geared tall, it likes 5.3 - 5.9, 5.45 was fantastic but it was fading quickly. I had amplimit 250, now I understand this was not the correct way.

I might try 5.45 gearing and experiment with the amplimit to keep the motor fresh.

I guess the gearing is less important because of the dependent timing but if the motor is in the sweet spot the feeling is better..

You need to press the little button on the USB adapter, after pressing the Program button in the software and while the bar is going across the screen . It then should load the firmware.

Then it's really really fast
Just ran outdoors for the first time and the car was very fast!
Advanced the fixed timing to 24, geared to around 5.5 and motor temps on can of 50 deg.

I have to do more testing with gearing, but a solid start

Thanks for all the tips Martin!

when you clicked "receive data" just plug the usb wire into the speedo, no need to push the button on the wire !

I found 5.4 - 5.8 to be the sweet spot of the 13.5 gm motor so I'd say 6.0 would be about right for a 10.5
forget everything you know by now about timing and how it works the motor. The new firmware is 100% different
I'd use a regular 12.5mm magnet

24 is about right, but 5,5 is totally undergeared (13.5 i guess?) as that's what I use indoors!

try 4.5, then it will be much faster

Thanks Martin,

I'm using 6.44 with 97290 12.3mm BRCA

So I should try 6.0 with 97305 12.5mm, yes?
