Hi Mikie thankyou for the response and I apologise for taking so long.
We have what is known here as Super Unleaded rated at 97 RON which I think is equivilent to the US 93 octane and Shell offer a fuel called Optimax rated at 98.6 RON which is what I always run with.
Your right with the changes in RAM, hence why it resorts back to normal after a reset. There's definately too much timing, I can here det (with det cans) at around 5.5k but only ever in 4th gear, 5th is clean and I can't reach 5.5k in 6th on the road
I'm used to mapping with GUIs and have no experience with Hex editors so I'm a little apprehensive to attempt any changes just yet, I need to do some more research. Can you just confirm something for me, there's no way to see where you are on the map?? So I guess it's make the change, road test, log and analyse or am I missing something?
Where do I look to remove the fuel, presumably the low det fuel map leaving the high det as is in case I run into any problems? I also run an early GC8 Impreza that runs AFRs around 11.7 quite happily so there's no need for the way this one's set-up at present, I struggle to get 200 miles from a tank!
Thanks for you help, it is very much appreciated.
