I have the option of buying a Cooling Mist setup (not sure if it comes with any sort of controller) for my boosted N/A (FC) project. Does anyone have experience with an auxiliary injection setup run from the e6k? I'd rather not involve any other computers/controllers in my setup if I don't have to (as well as not knowing if it comes with one).

 

The E6K could be used to control an on/off solenoid. Or, if you use an output configured as boost control, you'd have a 3D mappable PWM output to run that solenoid or solid state relay driving the pump.

 

WUH?!

On an E6k? This is news to me... Exactly what output is this? Turbo wastegate? That thing is useless. The only info I found about it was "it doesn't work". And that's on every message board, user group, website whatever I searched. I tried it with a boost solenoid and it didn't do anything. It's the one thing I immediately gave up on with the E6k. That's saying a lot as I'm the dumbass that made the S4 TPS w/ mech OMP, BAC & IAC valve, and twin scroll work with it.

Anyway... it depends on the cooling mist kit that you have sourced. Some have a controller, some are a simple boost switch. Both are easy and not a big issue to "deal with".

 

The boost control output on the E6K outputs a PWM signal based on load v. rpm. Which is the same structure as what I've used to drive pumps with some of the newer ECUs. While I've never attempted to use an E6K for boost control, I've used an E6X and it worked just as well as any other open-loop control. The E6X is essentially the same hardware, so I have to assume it will work on the E6K. But you know what they say about assumptions...

All that said, I agree that if the kit you're purchasing comes with a controller, I'd probably use that first.

 

There's no controller that he can find, but it seems to be in the original packaging with no missing slots (indented foam) so I'll assume it doesn't or shouldn't come with one.

So... I may or may not be able to use the boost control PWM output for this. I know it has an output for an auxiliary pump, but I presume that's just essentially an on/off switch?

 

C. ludwig: You mentioned 3D map which totally threw me off.

My5ABaby: Go to the cooling mist site and buy the boost switch. Only $30. I'm sure you could even find one on ebay for cheaper.

Don't use the aux pump output, i thought about it myself and realized it only works based on RPM, not manifold pressure.

 

You could use an output setup as NOS or VTECH. These both have load and rpm based on/off points. Or, if you just want an on/off switch, set it up as boost control and simply input pulse widths of 0 or 100%.

 

Yeah, you're right. It's not 3D. Not sure what I was thinking.

 

Thanks for the info guys. It'll be on a stock turbo (for now) if I end up doing it so there's some flexibility ther.
