Why would you ever want to activate the WOT switch by hand when your foot can do it when you go WOT?

For example, if a track has 3 straights (two short ones and a long one), but the controller will overheat after one or two laps, I might want to only activate the ESC through the long straight to prevent it from overheating so I can go through all ~10 laps still using the drag reduction feature and ESC-on-command before the session ends.

Think he is trying to control how much he uses it.

There is no problem hitting the WOT switch by hand when already WOT. The thing that is bad for the system is to "arm" the device when the WOT switch is already engaged.

Remember this system isn't really meant for heavy track duty, yes it can work with moderation but that is the key.

Thanks for the clarification. That's what I thought; just wanted to be sure it was the arming while WOT that was bad.

Yup. The way I see it, I really enjoy learning and pushing the car on the track with its stock characteristics. But if I already have the ESC installed, nothing wrong with taking advantage of the drag reduction and also the occasional boost while on the straight.

Just waiting for @shiv@vishnu to reply and let me know if a twin on the ESC tune while not using ESC really makes less power than on the stage 1 tune.

without boost it will make less, completely disarmed.

When drag reduction is available it manages to stay mostly above the stage 1 power level but it does in pulses. Refer to post 5 of the first page to see the difference between stock, ESC off and drag reduction

1. Back to the cooling mods, @Sojhinn @nlowell how well are your air ducts doing keeping the controller cool?



2. What seems the be the biggest cause of the controller overheating? Usage of the ESC itself, hot air trapped in the engine bay, something else?



3. Would directing air onto the controller be enough to keep it cool?



I want to figure a way to prolong the controller from overheating as much as possible. Extend the limits of the ESC per say.



4. If I reroute the WOT switch to some place where I can activate by hand, @fenton, do you know if there are any potential negative effects from clicking on the switch while I'm already WOT? (another way to think of it - activating super pursuit mode to activate the WOT switch while I'm already WOT)



5. @shiv@vishnu How does the tune on the ECU know when the ESC is activated and producing boost. Would it be smart enough to tell that I'm WOT without boost vs. WOT with boost (scenario on question 4)?



6. I think I remember you saying the performance of the OTS ESC tune is not as optimal as a stage 1 tune when I'm not using boost, is that correct?

Hey Tm,

I have seen improvements with my cooling mod. The ultimate test will be this Saturday when nlowell tracks his car.

But for the cost of the tube and how easy it is to route the cool air to the esc... Just do it. In my humble opinion it helps.

I think this is the dyno you're referring to:


Run 002: Stock tune
Run 046: ESC tune & armed with DR
Run 047: ESC tune & unarmed

^ is my labeling correct?

So the dyno was of DR all the way to redline without activating the throttle switch?

That is correct

TM,

Ask Rob to ship your ESC with Super Pursuit Mode. This allows you to operate @ WOT with just DR engaged.

[Sojhinn]

Ok seriously. San Diego county is fricking on fire. Sorry off topic.

I already have the ESC, but I will ask Rob for instructions on doing it myself. I'm thinking about buying the auto version of the center console switches and wire this "super pursuit mode" to either the extra sport or snow switch for a cleaner look.

Damn, I just saw the news. Stay safe out there.

You need some water and less sunshine!

Yeah no doubt about that. Shall I do some tests on how the esc handles soot and ash?

To truly test that, you'll need to remove your air filter.
