Its time for 3.5 or 3.6 rear gearing !!!
Dave..quick question. Anyone else who has some insight I'd appreciate your input.
I didn't read the whole thread so maybe this was covered. Ever since my 6MT conversion was done, my CC has not worked. I was under the impression this is because the 5AT TCU is gone. But now it leads me to believe it's because I stuck with the 3.3 gears and with all the manual parts now (drive shaft for one) would this cause my cruise control to fail? Anyone have any insight on this?

I looked over the FSM and it doesn't appear the CC has anything to do with the TCM. The CC appears to be controlled by the ECM's "ASCD vehicle speed control" via the throttle body. There are LOTS of systems monitored which can kill CC operation if something is out of spec. The thing that caught my attention was this note:
When any of following conditions exist, cruise operation will be canceled:
Clutch pedal is depressed or gear position is changed to the neutral position (M/T models)
Clutch pedal is depressed or gear position is changed to the neutral position (M/T models)
OCG35, my claim that you'll loose CC with the 3.7 gear was based off of what I read as posted in post #116 of this thread https://g35driver.com/forums/drivetr...al-swap-3.html. Apparently his CC started working again 1.5 months later. During my policing of every thread on G35Driver.com, I must have missed his update that the CC mysteriously started working again. I'll try and do a better job next time.
The reality is there is a possibility that you'll CC entirely or use of CC in certain situations when doing gear swaps on these cars. There's no rhyme or reason to it. Some people have lost of the use of it with 3.5 swap and a simple search of "cruise control" and "loose" will get you to that conclusion very quickly. Obviously the OP is willing to take the risk. I did too because I wanted the VLSD and deeper gearing for my auto-x stuff. People should just be aware that there are potential downsides to this modification.
BTW, there's nothing wrong with debating with someone and I enjoy it, but you seem to totally lack any tact. You just come out guns a blaze, looking for some sort of e-fight. You could approach things in a more civilized manner and say "Hey, I disagree with you and here's some information to back up my claim" rather than getting so defensive right from the start. It's been a long time since I've gotten into a worthless debate with you and I'm not going to start down that path again. People don't want to read that crap.

how is this post "guns a blazin'"? :

Let's be clear here - I made a simple statement of fact. One persona in particular wanted to contradict the "fact", however was unsuccessful. None of that has anything to do with you. My post to you was as benign as one could be. BTW, how could you continue to make such claim as fact based off of one post (in the link you provided)???
At the time, 245x35x19 all around. The tires only threw the speedo off by 1-2 mph since the rear stockers were 245x40x19. I've confirmed on many occasions roughly a 10mph inaccuracy in the reading when actual speed is 80mph. I've noticed that everyone else in here that has changed their FD has the 03-04 models, which is probably why my experience is different from theirs.

^Does the car "think" it's in neutral (AT) ? If so, that could be what's keeping it from setting... though I haven't tried to set my cruise in neutral, and even if I did, an 06 may act completely differently anyway.

Also, have you plugged in to the OBD so you can watch sensor values live?
No, I have not used an OBD scanner.
^Yes. Or vice versa (throwing it in neutral then setting the cruise)
I do need to go test it.
But you see the point I'm getting at right? If the cruise will not set with an automatic in neutral, and the 6MT swapped car thinks it's in neutral, then that's a problem.

My speedo is also off with my 3.7 swap by about the same as herrschaft's. The fastest I've tried setting the cc was 90 mph and it still worked, though I'm not sure what mph I was actually doing, lol.
^Hmmmm... also an 06+ coupe :/ I wonder....
Well, if your speedometer got off by the same percentage as the difference between the two ratios, then it must read off the vss instead of wss.
That would be another good use for the circuit I was thinking about building.
Man I need a test dummy!

listen im gunna just go with the 3.5 i dont hear of any prob with thoes. I have one more question for you guys, Does the 3.5 or 3.7 FD do anything to your tranny and if so what do i have to do to fix it dont want to loose my tranny for 7% acceleration.!!
^Not 7% acceleration. 7% higher revs vs 3.3 given same speed/same gear.
Transmission should be fine. Actually it's working less with a 3.7... in theory... of course a little "pep" will make you want to push it harder

Wait im confused now. 7% higher revs.. Please list the pros and cons of this thing i was so ready to purchase the 3.7 good thing i didnt ..!!!
