Greddy profec A solonoid wanted

just did a quick search as I was wondering if it was a stepper motor as opposed to a solenoid.
It appears that it is, which would explain the extra wires ;)
Then I'm certainly interested how the unit keeps record of the current position of the stepper motor. It certainly is a different approach then most other boost controllers :D .

Running mine at .8 the difference between factory .8 with the hi/lo bypass is done is like night and day :) brings the power in harder and smoother I found, overboost protection, hi/lo function, something else I can't remember lol and my favourite, the OTB or OverTakeBoost button :cool: I had it set to .8 and normal was .6
You can adjust the time off OTB up to 30 seconds too, this is why I love these wee units

I'm already wanting this piece of kit inside my car now:D Also have 2 greddy somewhat handy turbo timers one with a few lights and one which looks like a Christmas tree.

I can't find the manual however so if you have one and are able to share it I would defiantly appreciate it.

It seem like I do not have the permission to download it.

edit:
Got it from the greddy site, but dam it is hard to read:D

works like a charm now

The unit doesn't need to know the position of the stepper motor, just needs to know whether to open or close to control the boost.
It may self calibrate it's range on power up or something, but I doubt it.

Nice one, what does that mean then lol :D
Instead of a solenoid valve which is either open or closed, a stepper motor is used to open a valve in small controllable steps. It can do far finer adjustments that a solenoid could achieve.
It's just more complicated and expensive.

Cheers bud, that would explain why it's so smooth compared to the HDI solenoid controller I had before :)

Im on the profec b electronic boost controller. Great bit of kit on the more common valve used. Some good things happening here dutchie.
