14-1 (0.1)
15-1

geared at 4.96 and the car was really quick and temps were ok so thought I'd try a 13.5t class.

If I use the suggested settings of,

9-8
12-7
13-3
14-5
15-1

the car is slow so I need to use the settings from the 17.5t and have to gear it 5.93 to be competative.

so thought i'd just try a 10.5t with,

9-5
12-7
13-4
14-4
15-4

and it's sllloooowww ?

I always seem to have to use the 17.5t settings and gear it by temp but no mater what I geared it too it was barely any quicker than the 13.5t. I tried 6.5 all the way to 5.0 ad it never really made much difference until I advanced the motor timing but this only added 1 or 2 mph top end ???

What's some good settings for 13.5 and 10.5 speed passion motors do I need the motor timing up, down or leave it in the middle ?

I'm confused with it, any tips please the track is outdoors with a 45m straight, mostly fast flowing with only a few technical places.

Thanks.[/QUOTE

i use with 13.5 sp 3.0 motor on max timing

1-1
2-1
3-1
4-8
5-4
6-4
7-2
8-1
9-8
10-2
11-2
12-9
13-6
14-3
15-2
fdr 7.3 on a medium size track.
I must be gearing the wrong way ? the SP motor instructions give a guide of 4.8-6.0 ans also with the SP speedo pdf for 13.5t they say 5.5-6.0 mine does sound like it's still accelerating at the end of the straight.

Thanks.

Your RPM window for timing is much to narrow (#15 setting): Start 3000 & End 8800 This will cause the motor to feel sluggish (too much timing applied to fast) and generate excessive heat.

#2
The SC delay (#14 setting) of 0.1sec combined with your above timing settings is causing an excessive amount of timing being applied to the motor.

Your FDR of 5.73 would signal to me that you on a Big track. Have a look a few posts back for the setup I posted for 200ft track to get an idea of settings.

I would at least change your current #13 setting to 2 and #15 to 3. If it seems slow, don't be afraid to drop several teeth on the pinion. A zero delay SC setup typically needs a lot of RPM to go fast, and we typically will run it on short / med technical tracks as you get a lot of rip out of the corner with it.

How do you know what the end RPM is #15? I've never seen values applied to that setting, I didn't know that was the "end RPM" like on the Tekin.

If that is the case, what setting corresponds to a ~15,000 RPM end? I guess I am running a 6,000 RPM start and ~9,000 RPM end! That is no good...

I have an EXCEL calculator file built to allow me to input my ESC settings and show the RPM window. I'll post it later tonight when I get home from work.

You should receive a Purple Heart for your commendable work on the new SP software.

Hi,

Tried my SP 13.5t today with the GT2.0 and the 528 software. I used the 'instructions for the stock software' 7.0 fdr was very slow so tried the 6.5 well actually 6.44 and,

9-8
12-7
13-3
14-5
15-2

was pretty quick and temps were low. It says 'to get higher motor speed choose higher timing values' so I increased 9 (timing) and 12 (charger timing) is this correct ? it was faster on the straight and temps were still low.

I then increased 13 (timing start rpm) and 15 (charger timing punch) to give me more power in the short straights, is this correct as it didn't really seem to do anything ?

My temp on the motor got to a maximum of 60deg C, where do I go from here ? should I put the settings back to as they were and gear it up eg. 6.0 then check temp or keep increasing the settings on the speedo ?

Track is med/large with a 45m straight, and mostly fast flowing with a few small or slower technical bits.

Help confused and just seem to be going round in circles with my settings and gearing.

I just realized the same. Tried calling the SP number, but it doesn’t appear I have enough shipping time before leaving for the nats.

Is it acceptable to remove a section of case and clear tape over it or something? Anybody know where the led is located?

Jimmy, that is good stuff. you should be named humanitarian of the year. now the question is, for 17.5, what are your settings for a fairly large track with lots of grip?

thank you in advance,

rich

One assumes that the motor will continue to accelerate past the end point as this is just the point at which the last timing is applied, thus a motor could be pushed to 75000 RPM etc but the actual timing additions will end at the end point.

Also on fairly open tracks with a sweeper into the main straight most motors will already be hitting 12K RPM so is there any benefit to the additional heat produced by using lower start points as the Brushless motors have a lot of torque naturally and adding timing reduces torque for the gain in RPM's surely the higher start point will run cooler and use the motors natural 'grunt' prior to adding any timing.

Just for information purposes can someone at SP confirm this is correct.

thanks in advance.

Between the Tekin and SP I have run start RPM's ranging from 2,500 to 9,500 RPM and I must say they can pretty much all be made to work. They all just take different FDR's, motor timing, ESC settings, etc. There are a myriad of options that allow any one setting to work with a large range of values.

EDIT: I should add that this is in touring car, 2S, with 13.5's and 17.5's.

Just got this opened up. Looks awesome. I've got a couple questions. For #12 SC Punch, is that the value from the programming card, or the stage? For instance, Stage 7 is Value 8 on the programming card.

Also, how do you know which value corresponds with #15? The SP setup sheet says value 1 is Motor Hot - Max, and then it goes -1, -2, -3, etc. How does that correspond to your 200, 300, 400 values?

Thanks again for your hard work Jimmy.
