I hope my calculations are right! hahaWell John I am really impressed the milage/km you get with your car if indeed your conversions are correct and I dont see why not because you seem pretty smart. in the states our fuel is going down the tubes as far as quality and price lately and my Kjet is suffering for this it only gets about 205 miles per 9 gallons of fuel and if yhe car sits for a 2 week spell it runs really bad with misfire under boost then I make a few adjustments to get it to run good throughout the range and then refuel with fresh gas and start over back and fourth ........so for me I believe its time for some electronic management...........oh and back to the fuel here 10% ethonal wich absorbs moisture easily and degrades fast(looses octane)
I'm getting 445km with a 32L fill. So what ever that works out to be?
Your right about fuel quality though.
I've found K-jet is very sensitive to not only different octane ratings, time left at a stand still, but also brands of fuel. ie. Mobil, BP, Shell, Caltex. (not sure in the US though sorry).
Its also alot more sensitive when you apply boost to it too. Thats why I decided on a 'safe' tune with conservative timing. It does nose over in the top of 3rd on a cold night (hot days its ok), but thats pushing over the speed limit & rarely used. As long as it has some tyre squeal in 2nd & a bit of poke in 3rd to sprint to 100km/h its ok for a daily.
Plus, as its a daily, its always getting a constant turnover of fresh fuel, so it doesn't have time to go off (turn stale).
I have often thought about switching to a standalone & have a list of all the parts required to do the conversion on the 8v, but as I don't race it anymore, I think its better just to leave it alone as a daily & save the efi for the next engine (built 20v big turbo setup).
Even with a 'safe' tune, it can still put a smile on your dial. But as with most things, its hard to let go of what it was like as a 12sec time bomb! haha.
Thats why I have my ute, even though I get more enjoyment out of driving the Golf on most occasions.
