Dave-Yeti

Update on this one. I have now had the emissions roll back done and the engine remapped. Still not getting the economy I was looking for in the roll back I'd say it's possibly 5% better probably the remap. When going back to the mapper he said they have had some success with fuel filter changes and I'm going to try the throttle body clean see if that helps. Getting mid 40's around town with a bit of mixed roads.

Thanks @TR250man yes that's better than I'm getting and I'm trying quite hard to get the MPG going to contact some tuning companies to see if I can get the 'fix' reversed.

This is a great post just what I was looking for and believed to be the case. I’ve just checked and the E189 update has been done on my car. Was it easy to find a tuner to reverse the update?

Thanks I know but this is at relatively slow speeds I think it’s something else personally

Hello all, just got myself a Yeti 140, I’ve always loved the ‘alternative’ styling and my previous cat was a Seat Leon 150. Same engine but I was getting 60mpg in that but struggling to get much over 40mpg with the Yeti, has the 4x4 but don’t think it’s that. I think it’s the software (map). Has anyone ever has any success changing these to get decent mpg? Or perhaps any other tips, car drives well loads of torque etc many thanks.
