Hi SportsCarRacer


If I understand you corectly the GTxxyyV is the Dutycycle type and the GTBxxyyVK is the type where the ECU drives the DC servo Directly?



Is this the "povvo" type?


Thanks
Martin

Martin sent this actuator to us at Motec.

i've been able to figure it out!

It works on 300Hz (290 to 310Hz) and duty = position from 5% to 90%.
Pin 1 (round end) +12v
Pin 2 Ground
Pin 3 N/C
Pin 4 Signal
Pin 5 N/C

The signal pin has a pull up to 12v built in so just needs connecting directly to a switch to ground output.

Easy to operate with a dash or ECU. It would be interesting to see how well a VNT turbo works!

It just took him a single arvo



Thanks for the help Darren, Ill get a job for that VNT as soon as its back

I had help from SportsCar Racer! And i was about to give up, last attempt was just to throw a bunch of different frequencies at it,as i didn't know if it was CAN of freq control, or what the pin out was, so i was just lucky.
