Today I'm goin' to change the oil and the track is right next to this garage so I'll test it there again. I also think that it might be the O2 sensor!
Results and video later today wink1.gif

Don't get complicated before you need to! If the car is slower on the same track under similar weather conditions after you change X then suspect X before you suspect Y!

I'll tell you the problem straight away. The final drive ratio is shorter on on the 1.8. So, that's why you are getting a flat spot in third gear.

How did we get from a cam shaft to a final drive ratio?

The 1.8 engine has a different response curve which is matched by it's gearing. By installing a rougher cam, you lose bottom end torque in the rpm range. That is why I mentioned gearing. The 2litre has a longer final drive ratio as it has a smoother cam and more torque down low.

So mrrock, what do u suggest? To put my 2.0 cam back or as lilo shark said to get 1.8 ecu? I think it's better to chip it than to put 1.8 ecu...
