Remapping an ECU cannot be done on the fly as claimed on the Thorton chip tuning website. This performance map can then be programmed into the factory ECU with the help of an OBD II scanner. Lamda or oxygen sensors are also present in the exhaust system to check for the oxygen percentage in the exhaust gases, tuners use this data and design a performance map from scratch. A performance map contains data that is used by the engine control unit to determine the fuel injection quantity according to engine load. A close inspection of the Thorton chip tuning device reveals that it does not have the ability to flash or remap any performance map in the engine control unit.Īltering a performance map in an engine requires special equipment and trained personnel. It is just a fake product available online that claims to add 40 additional horsepower to the standard engine output after driving for 125 miles. No, Thorton chip tuning cannot enhance the performance of your car and improve its mileage.

There are a lot of good tune options at reasonable prices and well worth it for something that has actual R&D on the actual car it's going on.This blog will answer the following questions: does Thorton chip tuning work? What are the different performance chips sold by Thorton chip tuning? ECU remap, piggyback ECU or performance chip which one should you get? Does Thorton chip tuning work? Stay far away from that thing though for sure. I don't even like those because the car is not getting good data and you are basically relying on the o2 sensors to determine your fueling. It isn't writing anything to the ECU and isn't manipulating signals via a tune box, I'm guessing it just lights up and that's it.Įven the other tuning boxes out there need to connect to the vehicle sensors to manipulate the data. I'm not even sure what it would do through the OBD port, may not even do anything lol. Generic statements about functionality that clearly just copy and paste the manufacturer name in there. However, I've not read anything yet that suggests anyone having a bad experience.Personally I wouldn't touch that thing with a 10 ft pole. Seems too good to be true for a performance tune gaining HP, Torque and throttle response for only $100 and just plug and play.
