I'm sure that this is probably a dumb question, but would a 85 bmw 535i do worse on fuel with a conforti chip in it (Assuming still driven economically)? Also if so how much worse do you guys think it would be? Thanks so much guys!
Staying in shape one pedal or step at a time.... mabye helping out the wallet also
I never liked the idea of "Best Guess Chips" for performance... but I am interested to see what people may have to say about these for Fuel Economy. Unfortunately I doubt this company designs and programs these with fuel efficiency in mind... usually the map is altered to add more fuel.
Depends on what all they did. If they left the cruise part of the maps alone(likely) then the improved efficiency up top could help fuel economy. Now, if they made it where it is even running rich at cruise then you'd definitely lose economy.
I emailed them asking about where in the map the real tuning is done and what they change more of, timing or fuel.
