It doesn't matter how you remap the 4 pot Jtd, it still sounds like a bag of spanners, that's why I couldn't wait to get shot of mine when the 210 became available
And the helpful comment of the year award goes to.......
Anyway, the 1.9jtdm responds well to a remap. But, be aware that the extra torque/bhp may damage the transmission if not treated correctly.
If you stamp on the go pedal from the get go, let the clutch slip under acceleration, and generally act like a loon, you will shred the clutch, fly wheel and even the gearbox.
If you make sure the clutch is fully engaged before letting fly, all is usually fine. Mine had been mapped at approx 60K and the original clutch lasted until 96K, so pretty good considering the extra power.
Third gear in mine is pretty much like the third on my Saab 9-5 Aero, and that was quick!
First and second are pretty much gutless, but as soon as you find third, fourth and up the torque and power really impresses.
I'm averaging the same in the 159 as I was in the GT with the same (but unmapped) engine, so the extra weight of the 159 has been balanced out.
If done well by a decent company then it is a win/win for me.
I'm sure the 2.4 is a great engine with loads of power, a decent sound (for a tractor engined car) and has two exhausts! But if I could afford to run a 2.4 I could also afford to run a petrol car.
The 1.9 is all about the economy, its a compromise of an engine. A remap makes it bearable!
