Wastegate Actuator Adjustment

I'm trying to set the voltage for the IS20 style wastegate actuator on a DTR6054 turbo, on the bench, and even with the rod jammed in as far as it will go into the actuator, and not even hooked up to the wastegate, the highest voltage I can get is around 3.0v. When the rod is attached to the WG, I can only read about 2.8v when forcing the WG closed, regardless of the length of the actuator rod.

I'm using a USB power supply and a cut USB cable to supply the 5v, following the method shown in this video: https://www.youtube.com/watch?v=41mRzf5HZpQ&t=183s

Interwebs says it should be up to 3.5.

Is this going to be a problem, or will it clear up when actually installed on the car and try to do the adaptation?

Or is my WG actuator faulty?

TIA

get an is38 wastegate actuator, I never could get the is20 one to work correctly on the DTR

I found bench setting the WG to be a waste of time. I think it has something to do with the USB power supply used, sometimes it works, sometimes it doesn't. I though I had it benched at 3.6v only to find out it was waaaay off after installed in the car. The only reliable way to do it is if its connected to the car.

Hello, I am working on debugging p2563. IS12 turbo. Started a month ago on cold start. Now that I've tried my hand at adjusting voltage, I'm struggling to adjust things and I'm bouncing between reads of approx 3.0 or 4.5.

Can't seem to move it much in between.

Can anyone comment on the sensitivity of the adjustment rod? Can it go from 3.0 to 4.5 with just a half turn?

the cooper gate dosent work like the mahle. fire it up and let it set idle, shouldnt a take but a few secs. gate will be fully shut. note voltage. turn motor off, adjust rod to target 3.6v the necessary turns to do so. ignore voltage when motor is off it wont register correctly. fire it up again and check voltage. lather rinse repeat. be careful the DP gets hot fast, dont burn your arm.

Thank you will try more this week.

Tried again today. Improvised some insulation around the actuator rod and the downpipe using pot holders. Worked for awhile but eventually heat made touching anything difficult. I'm trying to do this from under the car.

Haven't been able to get voltage in the range. I find that doing the process on cold start, the vibration on the rod is so much that gripping and rotating is difficult. Once the idle slows down and levels off, the vibration is reduced, but by then, everything is piping hot and difficult.

Is strong vibration of the actuator rod on startup normal? Anyone do anything special in terms of idle, before attempting to adjust?

Want to confirm, turning the rod so that it threads further into the flapper arm increases / decreases voltage?
