Numerous problems after 65mm and tune
Alright, so let me start off by saying this:
Ive done what searching that i could, and while i did find similar problems, none of which are exact. Ive looked with key words and at this point, even if its been discussed somewhere that i havent found yet, I’m just gonna make this post. So yesterday I finally had the 65mm pulley and tune (both supplied by Vano V-Tech) and I ran into a few issues. First thing first: if I roll into a 20mph, and hit it, then I get the BAS/ESP light to come on and its limp till stop. Similar issues shown in this thread: https://www.crossfireforum.org/forum...elerating.html Ive cleaned off the sensor and, while i havent tested it, I can still feel an issue. Which leads me to my second issue: sometimes the sc takes a minute to engage. Almost like lag. And you can feel it kick in cause the rpms shoot up and the car bucks. Other times it feels like its not even there. Im stumped on all of this. Especially since none of this started happening until AFTER the pulley and tune. Car is drivable for now, but issues are issues nonetheless. So any insight is helpful (update): further investigation has lead to a possible lead involving a shot i/c pump. Ordering the Bosch one now. Will report back |
Re: Numerous problems after 65mm and tune
I doubt it is the pulley so it is probably the tune. Only thing you can do is put it back to stock and see if you still have the issues.

Re: Numerous problems after 65mm and tune
Im assuming its the tune too. But as of a few moments ago, i have no power under acceleration now. Like the sc isnt even there. Currently checking the pulley to make sure its right. And if anything ill re-flash the tune to see if maybe i messed something up

Flash back to stock and report your findings. |
Re: Numerous problems after 65mm and tune
I too have only lost power when the Intercooler pump stopped working. Just last week I installed a Eurocharger 65mm pulley and tune. Zero issues, except now I'll have to start a separate savings account to buy new rear tires. This thing now rips!

Re: Numerous problems after 65mm and tune
Thats my suspect is the I/C pump. The bosch 10 is apparently already in it. They guy before me said he put it in back in the low 30k range. The car is sitting at 106k now so its still possible

Re: Numerous problems after 65mm and tune
I also have that "Pump Always On" wiring mod, and one time I lost power again, so I checked that. The spade connector in the fuse box had worked it's way loose. Just something else to check if you have this.

Re: Numerous problems after 65mm and tune
Well i got some test wires so I’ll be test the pump to see how it is. And then more than likely doing the “always on”
mod for it too just to help |
Re: Numerous problems after 65mm and tune
Ok so at a glance the pump seems to be fine, haven’t thoroughly tested it yet. But we did a current test on the throttle body and throttle position sensor to make sure that those were working. While the sensor (thankfully) was fine, the throttle body failed to give any resistance back as per the specs provided in the instructions. So replacing that and see if that fixes everything.

Re: Numerous problems after 65mm and tune
So i (Hopefully) found the issue which seems to be at the root of it all. The gap on the pulley is roughly 3.5mm, which is waaay to big. And the old washer from the stock pulley was used instead of the new one.

Re: Numerous problems after 65mm and tune
So now that it is working how do you like the set up. I already have the pulley on, but not sure about the tune,

Re: Numerous problems after 65mm and tune
Yes 1000%
Inconveniently my IC pump went bad a week ago so I'm replacing that, and I’m still dealing with the limp issue, however I think I have those figured out. BUT I have confirmed it is not pulley or tune related. I also got the V2 TCU tune from Vanos as well. The car is a rocket when it all comes together and I love it |
Re: Numerous problems after 65mm and tune
Thanks, I guess I need to get the ECU and TCU tune. I just heard there were some issues with it but you are the second person telling me they like it and it made a difference. So I guess I go for it.
