Just reading some old posts, and I am wondering what size of track are you running on? How long is your straight, and is the infield technical or smooth flowing?

Our track is 30m * 12m, with a pretty technical infield. I run a considerably different rollout then you do. 78-82mm, with 20 endbell timing (novak 17.5), and 29 dynamic (everything on Max) with the 1S HW. I still feel like i am not in the cars sweet spot yet, the other cars are faster on the in field and the straight!

You seem to be the only person to continually dredge up the same question.
Either buy another brand that does log the info you desire , or use a separate logging device.
Whining about your wishes on here is clearly getting you nowhere, perhaps spam emailing HW would achieve more ??? ( Though probably not )
It seems most other users are after software that makes their car go faster, rather than bench racing with telemetry.......

Merry Christmas to you & remember to stress less

I ran the car up and down the street with the 5.5t and the speedy became quite hot with no heatsink or fan

If you are having some ESC heat issues, try sanding the top of the ESC down with some 400 Wet/Dry (dry), and working your way upto 1200 or so. The Top of the ESC should have a mirror like finish. DO the same to the heat sink, then use thermal epoxy to attach the two together. Use the smallest amount of epoxy possible.

Oh, and i am pretty sure this will void any warranty, but it will reduce your temps. (its an old overclockers trick.)

I was not using an ESC heatsink or fan.... Im sure even with the supplied tape and heatsink it would have been fine...

I lent my 120a to a friend and have not seen him since... he lives around 2 hrs away! I just want something temporary so i can use it again in 12th with no heatsink in the future.

Our track is approx.: 35m * 14m
My rollout is 57-60, and some even drive a lower rollout
But don't forget I drive 13.5T and not 17.5.

Here you have Jilles driving the track, some time ago.

If you want to compare, my fastest laptimes are 10.2 - 10.3

The software will not be 100% new it will be improvements like a linear effect from coming off turbo not so agrressive etc .If we went 100% then we would have alot of testing and alot of teething issues so every 8 weeks we will have some improvements for your guys to download as it is easier to make improvements to what weve got and easier testing one feature at a time then 200 features .

soon we will have the first update available.

I wish we could but the 120 amp needs twice as many mosfets and they will not fit into such a small package as the xtreme stock.

Maybe in the future when mosfets become smaller and more powerful then yes we could .

Help!

my extreme stock is going into fail-safe mode when its plugged into the receiver, or when the car comes to a sharp halt on the track.

If I turn the car on with the receiver lead unplugged, the lights on the ESC come on and the esc fan powers up. If I then plug the lead into the receiver, the power to the fan shuts off and a orange/red solid light comes on and there is no response. However, if I "carefully" slide the receiver plug in - the ESC works correctly and the fan does not stop and I ahve power. However if the car then takes a knock or a sharp movement, the ESC looses all power again and goes into the mode above and will not work until I unplug it.

What could this be?

Check if you still have a working steering servo, when this happens, if not it is certainly the receiver....

Yes i agree with you m7H its either a loose esc wire to the receiver or a damaged receiver .The solid lights on is a loss of signal
