Ok guys time to take a chill pill. If this 'problem' was anybody's it was JetCat's! You would all do well to remember how much support you receive from Dave even when you have not purchased from him. He went into bat on your behalf and may well not do so next time.

My take on this (for what it's worth). JetCat mapped the ECU for all climates and altitudes to keep it simple. Your new faster accel times will no doubt surge the engine in Johannesburg on a summer's day. Sure an ECU could be made that adjusts for conditions on the day but you would not be able to afford it! If you set the 120/160SX engines to 'fast' they are on the point of surging in this country in summer - just listen to the popping and banging. One reason why mine are all set to normal! In the end it's just physics. Instant accel times do not happen in jet engines.
