Fuel Consumption

[STI65]

I have an 06 Polo GTI which I have had for 3 years and it has done 69,000 kms. About 1.5 years ago I got a trial tune which lasted for 6 hours of driving time so I could decide if I wanted to buy the tune or not. I didn't. Since then the car has been running at about 12L/100km which is quite high. Although I do use the A/C when driving but I am not sinking the boot in at all. How much would it cost for VW to do a re-set of my computer or is it worth just taking it to my mechanic (if he can re-flash the computer)? or is there any other suggestions? Thanks.

I think when you get these trials they flash the ecu and it reverts back to the tuners version of the stock tune, not what you had previously.

I would think that unless you got a backup of your original tune then you're not going to get it back.

I don't believe so, I believe it switches to a stock-like tune.

I'd get CC, well priced and more power

Just what noone said, go with a tune, it'll probably be cheaper than having VW revert you back to stock

Tune it! I get around 11 ish in town sinking the boot and 7 ish highway with GIAC (I'm sure the others are much the same)..

I ran mine with std tune on and it was awful to drive. Maybe being in the game I am spoilt with the amount of tuned cars I drive. My Phase 2 would sub 6 at 100 on the highway and even with the billet turbo and mods it gets down to low 6s going to work.

550-600 out of a tank.

Phase 1 tunes would all be pretty similar.

It would be worth a scan first though before condemning software. Happy to look at it for you.

I am in Narangba. Happy laps tomorrow might be a convenient time?

What is a GIAC phase 1 worth compared to other tunes?

[philthy]

My GIAC tune was about $900 4 or 5 ish years ago..

Usual disclaimer: Stage 1 tunes are pretty similar. If you want to do more stuff in the future, think about what support and customisation you can get. If I was looking these days I'd get in touch with Gavin (h100vw) or Jimmy (Jmac). They're local, enthusiasts and will sort you out with a good deal.

550-600 out of a tank? Mine is always around 12L/100kms as well and I do have a bit of a heavy foot but I see 380kms a tank max and it's still on a standard tune lol
