Unitronic Chipped

[DubSteve]

If the tuners were prepared to submit their product for controlled, independent testing, ie same dyno, cars, conditions etc, then we'd a better insight into what claims were real and what weren't. Maybe we should contact Choice magazine and get them to do it

Hahaha however I think that is the only way to tell what is fact and fiction overwise these kind of discussions will be going on for quite some time to come.

it has been done hasnt it? at the dyno day.. same dyno, same day, same cars different chips

No

Im talking about stock cars with different flashes, cars running the same setups everything, thats how it can be done, I think we just need to have people put there car up as test ginny pigs and I'm quite happy to do it but there are only 2 that I know of that do the mk3

For a thread that started on Unitronic, its escellated into the other brands.
I wonder what sort of lifespan you can get out of components using this type?
At least the stage 1 Revo, GIAC and APR or whatever are well inside the limitations of turbos ect.as has been proven.
Just my 2 cents worth!!

Oh, and Steve, if stock cars are to be tested, ?I will put my money on Marcos Ambroses thanks!!!

Marcos Ambrose has a VW?

However you do make a very valid point there Andrew with its limitanions and etc, however looking at the vortex and the people that do the BT kits and use Autronic you think that they would have taken into consideration these factors.

That's what I thought about the Dyno day in Brisbane a while ago. But then figures were all over the place due to a dyno operator that didn't care and he just wanted to get cars up and running as quick as possible.

When we did the Polo dyno day with only 6 cars and a dyno operator that made sure all tyre pressures were identical, all cars were tied down the same and with intake temp monitoring etc all figure came out within 1kw of what was expected the whole day.

Every car we had was APR tuned (due to it being the only option in Brisbane - REVO is out at Toowoomba). It would have been interesting to see the same day done with 2 of each tune only (APR, REVO, GIAC, CC, APR, REVO, GIAC, CC).

I remember decades ago reading US VW mags telling you how to get 1000HP out of beetle motors. They didnt say they would only last for 20 seconds on the dynos! The point was, they got 1000hp out of them!!!, not actual figures mate, just an example!
Maybe the guys doing the mods on Vortex dont expect the turbos to last 100,000 kms?

Neuspeed for the win...

Ebay powerchip FTW !

Not Unitronic related I know, but tuning industry related nonetheless..

Can anyone confirm whether stage 1 Revo tunes (ATF) are getting claimed/matching outputs ATW? They claim 195kw and 408nm for Golf GTI and 158kw 322nm for Polo GTI (although Polo dyno is for a Golf 1.8T)

The first dyno sheet I posted in this series is basically the stock REVO Stage 1, with 123.8KwATW. I'll let someone else do the maths to convert it to a flywheel equivalent. It would not be far off REVO's claim, IMO.

Hahaha thats the last thing that people want to see here lol.

That's almost exactly what the APR tune got on the dyno day we just had. But they claim 152kw. What do you mean by stock REVO stage 1? Do you mean a 100 tune with 100 fuel? or a 98 tune with fuel you can buy in Australia still?

[GT3]

According to my calculations (123.8kw atw = 166bhp atw, FWD cars you add 10 bhp to the wheel figure then divide result by 0.9) ..so 123.8kw atw = 154kw atf.

That also means that Revo stage 1 Golf GTIs would need to do 169kw atw to match their claims of 195kw atf...

Isn't it just a 20% drivetrain loss? Which is about the same answer, just heaps easier.

More like 9%-15% drivetrain loss. 20%-25% if on automatic tranny
