Thanks piggy.


Ive been battling with a fluctuating fuel map for sometime now and id finnaly had enough of it, some days it was perfect other days rich as arseholes. After various datalogs and late nights studding the data and chats with guy at omex we finnally think we have sussed it! Turns out lambda feedback was on somehow causing the fuel map to rely on the wideband sensor. :/ Turned it off and noticeably i knew id have to rescale the map. I did a few hours out on the road on my own slowly adjusting things stopping in layby after layby finding various different roads to suit the load points i was looking for.




Left is old right is new

As you can see its progressively changed and now is much more stable and reliable. I dont believe theres any more to gain from my ignition table in fact ive had to take some power out from the bottom end and going from my plugs it seems on par. Im due to go out with a friend on the weekend with it and let him drive it while i perfect it alittle more while in the passenger seat. I do believe the map is trying to tell me my injectors are running out of puff and where the charger peaks, Im no way an expert in this but have been shown and taugh abit thanks to sandy and will be getting him to check over it once finished.
