DIY Powervalve mod

[rdstars]

Here is a quick outline and photos on how to mod your Powervalve Controller.

Now I take no responsibility if you break yours, it goes belly up or even if your a complete "Div" Mine works so this is how I did mine:

Tools needed:

Soldering Iron ( and solder )
Scalpel
8 way Dill switch

My board was dipped from factory to prevent water ingress ( I would guess there all like that ) so the area you need to work on you need to cut and peal the coating away.

Next you need to cut eight tracks, these are behind the where the pins are soldered on the right side of this photo, sharp scalpel, score a few times and you should be able to lift the track away.



Next scrape away the thick part of the board at where the bottom of the switch is to be soldered.



Next solder the switch in place, job done. Sorry I could not do a full step by step with photos but I did mine over a year ago but hopefully this should help. I will try and find the dip switch settings and post them up.

Some more photos:

Cannot find the dip switch settings ( dam things going missing on my pc ) Sure someone can pop them up.

Thanks to Fotis for this info.

There are 16 pins under the circuit board on one side of the IC and each group of four pins sets different settings depending which one you are grounding.
The first group of four pins (from the left) controls the type of the engine(1-cylinder or 2) and the servo movement. I am not 100% sure what else it controls but those two are confirmed.
The second group controls the opening RPM with the following values:
1 2 3 4.......3600
- 2 3 4........3900
- - 3 4.........4320
- 2 - 4.........4860
1 - - 4.........5100
- - - 4..........5400
1 2 3 -........5640
- 2 3 -.........5880
- - 3 -..........6420
1 2 - -.........6540
1 - 3 -.........6720
- 2 - -..........6840
1 - - -..........7140

A number means that the pin is grounded otherwise is open.

The next group controls the ending valve movement:

1 2 3 4.........6690
- 2 3 4.........6870
1 - 3 4.........7260
- - 3 4.........7380
- 2 - 4.........7740
1 - - 4.........8100
- - - 4.........8400
1 2 3 -.........8680
- 2 3 -.........8880
- - 3 -.........9260
1 2 - -.........9660
1 - 3 -.........9860
- 2 - -........10050
1 - - -........10350

Finally the last group controls the speed of the servo and again the angle of the servo motor.

I found out these values using an oscilloscope

By soldering a DIP switch there you can control everything without soldering the pins.

Fookin hell mate,clever stuff. I am impressed. Totally baffled,but impressed.

Mine had the full 12 fitted by the greek bloke.



Worked well.

Obviously you would not use a knackered one. Obvious answer really ;D

The Greek bloke says he will do it if it's knackered look on eBay , i just put one on my 31k well worth doing and noticeable throughout all gears thanks midlifcrisisrd best money I ever spent
