Hello!

I have ’07 G35x sedan. I had issues with the cold engine start, so I went to my local dealer here, in Ukraine and he
found it to be ITB07-045a

This ITB is suitable for me, I had ECM part number: 23710-JK69A_V36_VQ35HR_4WD_AT_ACC
and I had to change it to ECM 23710-JK69C_V36_VQ35HR_4WD_AT_ACC. (Rev. A -> Rev. C).

My dealer found, that Rev. D is available for my car and upgraded my ECM to it.

But now, my throttle sensitivity seems to be very low with this Rev. D and I want it back to be high!

I found ITB08-017a that applies to “throttle sensitivity” and makes it lower and can be applied to
Rev. A, B, C – but it is not written, that it is Rev. D.

So the questions are:

1) Does Rev. D “fix” this “high throttle sensitivity” and Rev. C does not?
2) If my dealer will reprogramm my ECM to Rev. C, will I be happy?
