I asked about the ECU remap about the one provided by GM.IThere are a lot confusios going on this remap as some say newer one comes wit newer ecu settings.What I heard is its free too.
In somee other forum I have seen both people getting low fe and getting high fe(around 20kmpl!).
Our beat has petrol leakage (some rat works and the dealer say around 12k INR to repair it,will have a discussion on my ownership report) so cannot be sure of the fuel efficiency figures.
Do start an ownership report of the beat and I think this is PS variant.
OT: Did you post this car for sale in classifieds.
