2016 E4 High Voltage Conversion in SD

Clear view can change most of the parameters… call me newbie but I can’t find how to put it in Operational again using just the clearview.
It should have that option, I refuse to think that they let you change throttle, voltage, contactor and plenty of things and they don’t have an option to put it in Operational mode.

What is the best way to get a free license? I didn’t see anything when I searched borg warner. I did make it to the Sevcon site but didn’t see it there.
I’m interested in purchasing or renting the dongle.
I did see a place to purchase the program from Kit Elec Shop - All the equipment for your electric vehicle projects in France for 30.00 bucks or so but they couldn’t take my credit card at 1 in the morning. I’ll keep looking or maybe find some direction from the guys here.

(If I made him buy it back I would have to go buy one of Grants cars.)

I got my license from kit elec shop, worked out great!

Did you need to buy their dongle? No I guess not. :slight_smile:
Will they do that for anyone, or only with purchase?

Cluster Wiring,

Green and Yellow should be CAN.

Wondering what are the other ones?
The service manual I have doesn’t show the pinout,

Sorry for the off topic

Anyone, they’ll e-mail you instructions when you purchase. Nah, no dongle needed, a really nice guy let us borrow their dongle :slight_smile:

Actually mine does. I had it marked when repairing Mike’s.

1 and 2 are can bus.
3 and 4 are +12 3 being switched RD and DB
5 is common BN

Knocking on some wood here… but I think I might have my car dialed in.

I got the maintenance port CANBUS cable built so I can monitor the car live and download/upload off the bench. Both @MaxAtMaxMarine and @djgabriel2004 sent me their DCF files (thank you BTW), decided to use @djgabriel2004 since we’re both e4s. I changed the contactor settings per @MaxAtMaxMarine and the battery configs to match my smaller 20s.

Out of the garage, I actually moved backwards on the errors and was getting random faults at 50% throttle and all the time at 100%. I then monitored the throttle start and end voltage so I could put actual numbers into the DCF. That cleared my 50% throttle errors. I’d still get an error at full throttle. -

22:28:51. Node 1 fault set (0x4883, SRO Fault, data 0x00 0x00 0x00). CANopen Error Code: 0x1000
Potential Cause: FS1 (foot switch / throttle) active for user configurable delay (0x2914,2) without a direction selected.
Suggested Action: Deselect FS1 (foot switch / throttle) and select direction first

I then changed - End Throttle Voltage from 4.25 to 4.3 and that seemed to solve my problem. I punch it from slow to fast, fast to fast, no error. The caveat to that is I haven’t tested it extensively, just a couple laps around the block.

So much for this thread being a “How-to”. maybe when I do @smspring 2016, it will be straightforward :wink:

I have to head out of town tomorrow for the week. I’ll do more driving over next weekend and report back.

Minimum of 10% above actual throttle voltage. Will fault if it ever spikes above setting in dcf.
Higher is safer, you can always look at throttle value to see if you get full throttle =1.
I need to look at my files to see if speed is limited by throttle setting. it seems a good idea with hills.
Do we all have the same sw in controllers? 706 I think

Hi
what do i need to connect to a Gem 2017 ?
can i use my very old sevcon tcl85 progg
anyone have a picture of dongle and cable to use ?
thanks

All newer Polaris vehicles have a can bus programming port.
Uses a Delphi 150 series plug.
You need Polaris wrench to make changes or monitor.
Can also connect to the controller over the can bus, but there is nothing in the controller affecting speed. Afaik . All that is in the vcm. The vcm sends a request for torque, so it may be possible to crank up the maximum torque available. I don’t know of any hacks. I found it easier to swap the controller with one that is easily programmed.

Two the pins access the can bus and any can device can communicate.


ok thanks
i have 2 can device to try with
do you think i can monitor throttle and FoR switch with sevcon software or only with Wrench soft ?

Same for the start voltage? Should I be 90% of the lowest observed?

Will check when I get back home tomorrow.

Depends on your skills. I know that I cannot.

No, afaik the start voltages can be set much lower. Which should reduce the dead band in the pedal.

You must keep the 2:1 ratio (or actual throttle volt ratio) on both ends so that the “value” of both track the same.

.5v to 2v = 0 to 1 value
1v to 4v = 0 to 1 value

Do you guys think I should put a heat sink on the controller?
I was hitting the pedal hard. I wanted to push some limits :joy:
(No errors)

Not sure what’s the max heat it can tolerate but Driving the same way but with 4 persons in Florida might overheat it… what do you guys think?

This battery is amazing!!!

I’m going that route. What version dongle worked with that software?

Nice display :slight_smile: How fast did you get it going?

Max I’ve seen was 47mph but it was a curvy road and scared me. Based on the specs it should be In the 60’s

WOW. I was scared when I got mine to 40. The suspension is so soft on the new ones and with less wait hitting corners at 40 reminds me of my 4X4 days. It really sways to one side or the other. I just need to drive mine more to get used to it.
