I recently installed a CR190 / gtd1449vz turbo on my 2016 TDI wagon.
How can I adjust the charge pressure actuator? I have a vcds hooked up and it shows the voltage at 8 instead of the desired 3.6. The actuator has no threads or obvious way to adjust it.
The car isn't making much boost until 3000 rpm and only is making a max of 18 psi of boost at 4000 rpm. I have a Kerma stage 1+ tune on the car and also tried it with the stock tune, which had the same problem. I dynoed the car and it is making less power befor 3500 rpms and a bit more from 3500-4000 rpm.

On the drive home tonight I pushed the car pretty hard, it’s quicker than with the stock turbo at high revs maybe the turbo vanes are stuck at the setting for high rpm? It’s a new turbo, a hybrid cr190 56mm from Xman. I’ll triple check the vacuum lines tomorrow. Has anybody had a new turbo with sticky vanes before? From the dyno runs we did after the install it made 20hp more above 4000 rpm but 20 less at 2500 rpm. I logged a couple of 3rd gear pulls and the boost peaked at 4200 rpm, way later than it did before and the boost climb was very linear, before it shot up quickly before 3000 rpm.

I would resist pushing the car too much until you get a proper tune for your hardware. I'm running Kerma 1+ also, love it. I emailed them about support for the Xman hybrid as Kerma offers the CR190 themselves (along with required tune). Understandably, I was told that's what they support. Makes sense from their perspective and from customer perspective in most cases I imagine, keeps everybody's expectations in line. I think you're going to need a custom tune to fully support your turbo but at minimum I would try to get a standard CR190 tune flashed before giving it the beans.

OP, so you're saying you have GTD14 series turbo with 56 mm compressor wheel? That silly C/T matching will never work properly. You might have some other issues as well but that's the root cause.

Actuator adjustment is done by loosening the three screws that hold the actuator to the bracket (the holes are slotted to allow adjustment). With the ignition on and VCDS looking at turbine actuator voltage, you slide the actuator unit up or down until the voltage is what you need. I've heard really good things about the CR190 with 56mm wheel from Xman, I don't think that's an issue.

Thanks!

That worked. I tried it once before but was too stupid to figure out that the voltage shown on my OBDeleven vcds was as a percentage of 100 so 27.77 is 3.6. I also replaced all the stock hose clamps with t clamps which fixed a boost leak, the car is now much happier. After the holidays I hope to get a correct tune for it.

Sweet... looking forward to impressions on how it feels and serving what it does on the dyno if you get back on it, especially once it's tuned.

I assume you're not running stock emissions equipment? Have to keep mine in Cali so I kinda ruled out the hybrid worried I'd be leaving too much on the table without something less restrictive. My understanding about the standard CR190 is the primary benefit (compared to the 1+ tune I'm running now) is felt at high RPM, not sure it would be worth it for me. I'm jealous though, enjoy it.

I live in Mexico City which has strict emissions testing so I kept the emissions intact, the tdi cars sold in Mexico have the ad blue disconnected.

Now that the car is running right I’m happy with the turbo even before i get a new tune. Mexico City is 7500 feet high and my commute goes over a 10,000 ft pass on a steep and twisty road. The stock turbo’s boost was done by 3000 rpm at the high altitude, the new turbo is pulling well to 4200 rpm which doubled the usable rpm range, to me a very noticeable change also I was hitting too high exhaust gas temperatures on the steep, long mountain pass. With the added rpm range the car is more fun to drive? To me it’s worth it because I drive often at high speed 80-110 mph up steep hills so every rpm extra lets me pass all the slow buses quicker and safer. If I lived in Kansas and was most concerned about 0-60 I don’t think it would be worth it.

Love the cr190, was trying to find the largest to fit on there with stock factory equip, this seems like the one. I too have heard great things about xman, don't know how to get one from him tho, and cannot find examples of a gtd1449vk - only the vz.
gottuned.com has a gtd1449vz with garrett internals and a 7+7 blade which I'm prob going for. If I had to worry about emissions then kerma is the route, but wrapping rawek's cold air intake, neuspeed's turbo discharge (if it'll fit:rolleyes:) and a straight is what I'm working on. cr150 passat.
Had a mkvii jetta cvca with the cr190 3" to muffler making 181whp and 310wtq dynoed, then put Bank's 3" cat-back on and welded the connection for a true 3" through. Didn't dyno but would have boost creep and flywheel shudder while merging onto highway (dsg). Manual mode helped minimize that.
I'm trying to get that 78mph to 113mph boost sprint back. To die for, used to flex roll bar on mountain passes up in washington state/ 73mph on 35mph corners, dry, full confidence.
I normally drive with no ac, which caused the glowplug light to come on and cut my throttle (overboost); running the ac minimized this occurrence from 8/10 times to 3/10. Malone stage 3.
I found as well that I would turn my 507 5w-30 spec oil to smoke, caused oil light on dash, pull over and uncap = white cloud on side of highway for 10 minutes. Liquimoly 5w-30 or even better 5w-40 (doesn't burn off nearly as quick) became my go to 505 spec. Also, while enjoying my foot into mine (all else stock internally) I found I would go through a 1/8th inch of coolant in 6-9k miles. This is based off of sea level, high humidity, 90 degree average day temp outside. (florida).
Sorry for the rant, rare to see others with anything done on the cr150 cvca.

My Golf and jtree's GSW are CRUA but it's still rare to see discussion about CR150 power mods, outside of adjat84th.

jtree... cool to hear it's that noticeable even with full emissions equipment. With your driving speeds, at elevation, combined with the hills you can better use the CR190/hybrid. I drive slow and everything is flat, haha. Besides the time I was intentionally pushing the car about a month after going 1+ I've never bumped the EGT limiter. My typical driving never has me in that situation.

It would be fun to feel the car pull through 4k+ but probably not worth it before doing/finishing mods that I will use everyday. I'll continue to live through you guys.

I was able to load on a stage 3 tune from Kerma last night and the difference is dramatic, it feels total different from the stage 1+ tune. I will take it to the dyno after l get a DSG tune in a couple of weeks Without a DSG tune the ECU cuts power often unless you roll on to the throttle slowly. It's now much too easy to spin the wheels in 1st or 2nd and the traction control light even flashes in third. It feels a lot like my previous Golf R below 5000 rpm except with more torque and less traction. I'm probably going to add a LSD and then stop messing with this car and start building up my new track/rally toy, a Renault Clio 182 that will also get a turbo:D

The good thing is, with the hot uphill sprints in your daily commute, the DPF should never need any regen; it will do it all by itself! :cool:
Please report EGT on those runs. MkVII have watercooled exhaust manifolds IIRC, so I have little worry. I am switching to Evans waterless coolant in my ride.

Nice, did Kerma send you their CR190 tune? I've been driving my car with the stock tune flashed for the past month (trying to pin down an intermittent glow plug cel that started popping after I installed the digital dash, seems to be a software issue though, not tune related). I can't wait to feel the transformation between stock and 1+ again... your car sounds like a blast to drive. I'm manual so down the line when I upgrade the turbo I'll need to do a clutch at the same time or very shortly after.
