Title says it all.
Living in Europe corresponds to high gas prices, so i was wondering if an ECU remapping might save some money in the long term. Also… are there any negative impacts on the engine or other parts that should be put in consideration?
my 2017 chevy spark dumps fuel down the intake when engine braking down a hill. i presume they do that to keep the catalytic converter warm.
if your car does that, what you may be able to do is wire in a manual kill switch for the injectors.
