Mine didn't get any worse.
I think different fuels(same octane rating)
seem to make a diff to my consumption though?

 

The flashing of the car was very easy ! Because there is a holiday in USA today, I have too wait until tuesday !

I give you a update when I have get my files tomorrow !

 

I have got my files ! Again very esay too install ! And the car is alive and angry. I read of 1.0 bar !

I am very happy with FVD ! Really good product !

 

I know someone will chime in here and call BS on this, but I routinely get 21.5-22mpg with the FVD Stg4 setup. As I recall, my previous average mileage was roughly 18mpg with a REVO tune, exhaust and DV's.

 

I contacted FVD to see if I could use my existing durametric cable. They stated it was not the same.Thought I could save some money ;(

 

Another tuner (Revo tuning ) claims that some client will see a improvment in fuel efficiency.
But after I have reflash the car the fuel efficiency is not good at all ! I use 1,55 liter / 10 km. And that is when I drive the car as economical as I can ( and thats just borring !!! )

Is this normal ? Is the car running too rich ?

 

thats not good, most guys are saying they think they are getting better mpg since the flash.. maybe its a FVD thing?

 

how do you choose which ecu flash to go with????

 

sandvik contact FVD thats not normal

 

I bought my GT2 with a REVO flash and it typically got 15-16mpg as an average, both on the OBC and as actually calculated by me.

I have since switched to FVD and my mileage has increased to 21-22 average, also on OBC and as actually measured by me.

Same driving style and type of driving with both different setups. FWIW, the FVD is now also using a 5bar FPR, which IMO should get WORSE mileage.
