RSchip for KK

Looks good too.

But one thing I'm not sure.

Since I changed my tyres to MTs on 18" wheels, the dealership adjusted the ratio, type diameter to wheel rotation rate, to the maximum that the ECU would accept, and the speedometer still can't reflect the actual speed of the car, mileage and fuel efficiency are affected as well.

Actually speed is no big deal as GPS will give a pretty accurate reading.
The problem is since the ECU is getting inaccurate data input, it kinda delays the gear shift for the car, as the ECU thinks the car is travelling at a lower speed than the speed it believes the next gear should be using.

So my main doubts lays in if I put this chip on, will this issue get worse?

Yeah know what your saying. Mine reads under and the tcm thinks it's reading right. But my big issue is with the tcm itself. The NAG1 shift drops rpm too much. This the shift into next gear is quick but at too low revs for my liking.

Wish someone could sort that out.

I have a Steinbauer chip on my KK Diesel and after nearly 50,000 kms I have had no issues. It does not use any more diesel except when I give it a good squirt. When installed, both power and torque increased by approx. 20% as shown on the dyno readout. I have not got the paper copy now, but the torque was about 550nm. I tow a caravan regularly and just hope my vehicle will last many years as I can't find a replacement vehicle with similar power/torque. Not cheap though. I have one also on a Hyundai Accent diesel and from memory paid all up about $3000 for both units.
