upgraded the spring in my revision G to a 20% stiffer spring which gave good results, holds closed better and with much faster action, anyone else done this
-
Can you say a bit more? Any analysis to back it up (I guess VCDS logs of specified and actual before and after)? Any drawbacks?
I have just fitted a new G to mine but didn’t know that updating the spring was something that people do.

I've heard of this being toyed with, would be cool to see any logging results that back up an improvement if possible to capture.

It isn't something people do wholesale, but rather something R-Tech tried once or twice. Possibly an experiment brought on by the fact GFB use a stronger (than oem) spring in their DV+ kit.

i dont have access to logging equiptment but thinking of investing in ultrgauge, i had a problem last year with a revision g not hold at wof from 3rd gear on, could hear the whistle past 4000 rpm, it was purely experimental, and tryed numerous different springs and landed on one that was around 20% thicker, that stopped the whistle and car pulled harder from 4000 rpm, it ws rtech that gave me the idea but i dont think they ever put it into production but i could be wrong, im not sure if i had a faulty g or if just wasnt holding all the boost at stage 2 level, but it definately worked for me, seemed similar to the uprated bypass valve for the old cooper s, shut quicker and must have been sealing better from my test.

What spring/where you get it from? I've got a couple spare rev g's in the shed that I wouldn't mind experimentinting on different springs with in future and doing some back to back logs to compare when I get time.

Interesting. To be honest I'd imagine that the Rev G can hold big boost, so Stage 2 would probably be OK. My G replaced an old C that was actually totally fine.
Let us know how you get on. VCDS worth having if you are considering it. Actually let me rephrase that... VCDS is hideously overpriced for the experience you get, but it appears to be the only way of getting the functionality.

i cant remember if it amazon or ebay tbh, but luckily i have quite a few left so if you want one i am happy to send you 1 in a letter if you want think i got 10 in a pack, i am aware that the g is supposed to work ok but i have seen quite a few post from people who didnt have a torn diaphram and still had it leaking and getting the same whistle i got under wot, thats why i tried different ones, some of them were too stiff so had to work my way down different diameters until i got one that worked okay

Wait until you've witnessed the VCDS Mobile experience :doh:
When it comes to VAG cars, Ross-tech have something unique - the ability to translate all of the proprietary PIDS, and by far the best controller interrogation/manipulation out there. It's the closest thing to full dealer level diagnostics. If that's what you want, then it's extremely cheap. If you just want a casual code check/clear fault codes etc, it's not for you.
You think VCDS is bad, stay away from BMW INPA, and Mercedes VeDIS. VCDS is user friendly GUI-tastic compared to those.
The rest of the world sticks to OBD2 standard PIDs which every cheap arse scanner on the market can decode. The Germans? Of course not. Until Ross-Tech came along, scanning VAG cars was dealer only, costing £100 a time. Again, VCDS isn't looking so hideously expensive now is it?

My point was that the experience was poor for the price. Totally see the value in the functionality! :smiley:
It just looks like a business that isn't looking far enough ahead. If there is anybody else that can translate the PIDs and create a usable app then the whole Ross Tech business will get blown out of the water. I get the impression OBDEleven has come a long way in recent years and for me, it was a borderline case whether to go for that or VCDS.
Sorry OP for going off topic! :doh:

I know where you're coming from. As much as I like VCDS for what it can do, I find Ross-Tech as a company to be completely apathetic.
The basic GUI hasn't changed in decades, VCDS Mobile is complete bug ridden joke and the threat of competition (OBD11 being their closest rival) doesn't appear to phase them at all. They're not interested in innovation. They're a typical American "if it's not broken, don't fix it" company. We all know how that panned out for Toys R Us and Blockbuster don't we :grin:
Anyway, hopefully OBD11 will get better and better over time and become a viable alternative.
