Whats the difference between a MTM tcu chip and a tcu remap besides the obvious one's a solder in chip and the other is software? Can the MTM software not be flashed to the standard tcu? Are there any benefits that one has over the other?
I'm only asking as i'm nearly ready for a remap but my current tcu has been flashed by DNA tuning by the previous owner so you can drive at 30mph in 5th. Originally the previous owner had the ecu flashed too but that went horribly wrong (checksum error) before i bought the car so now has a new standard ecu.
Does having the tcu allowing 5th gear at 30mph not put more strain on the torque convertor / gearbox trying to lug around 2 tons at low revs?
