Help with ECM plz!

[harp00n]

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 hefound 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 toRev. 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?

hello first you have to explain yourself a little bit more. or maybe its just me since i have no idea what you are asking for. and second you might more correct answers positing in the right correct section of the forums, under engine and drivetrain.

Not sure what you speak of... but have your dealer do the adjustments and see how you like it.

It costs me about 70$ to change my ECM, as it's USA-market car so my local dealer orders ECMs from the USA (and I have to wait 5 days).

If you work as Infiniti technician, can you ask somebody at your work about my problem (lower throttle sensitivity) - maybe car's electrician? So the main question is - if I buy this Rev. C ECM, will it give me back this "slightly increased throttle sensitivity"?

Today I came to my dealer and he said he can order and upload the older Rev. C of the ECM to my car, but he doesn’t know if it helps.

So, the question is – will this Rev. C (23710-JK69C) help me to get my “increased throttle sensitivity” back? Or was it already fixed in Rev. B, Rev. C, so only Rev. A had it? I don’t want to waste 70$ for nothing.

Well, my car adopted for my "spirited" driving, and maybe I am adopted too I think, for the winter (and it's REALLY cold and snowy here) it would be better to use "less sensitive" throttle.

But, at spring, I want to come back to this question so I gather information about differences between Rev. C and Rev. D of the ECM!
