Sorry. I've just downed a Henny&Coke on an empty stomach, explaining the intricate technicalities, pros and cons of changing final drive ratio might not be the best idea right now (evidenced by the fact that this post would be completely illegible, were it not for Firefox spell check )

Perhaps someone with a slightly lower BAC would care to chime in?

 

HAHAHAHAHAHAHA i like Henny & Cranberry !!

 

Please Some one explain the pros&cons of having a 3.5 Fd over the 3.3

 

I'll have to try that! ............ I have no cranberry juice.........





.........another Henny&Coke it is!

 

Make Sure the G Sedan is Parked...Please ii Dont want to See a Wrecked Thread from you!!!!!!!!!!!

 

come on man, you gotta at least do SOME of your own research

 

LOL i have but im just a lil confused thats all..!!

Don't worry dude. I don't drink and drive. I drive dangerously enough sober

^+1. You just gotta do a little digging:

 

^ well then read some more!

ouch!!!!!!!!!!!!!!

 

I think that may be what the problem is. The clutch pedal does not have to be depressed in order for the car to start. I will need to talk to them and see exactly what they did. I think the car thinks it is in N so maybe that is what the problem is. I will go talk to them and hopefully get it back working.

 

Nice theory Dave. And good luck Canadian! Hope that cures it. And it would give a bit more insight into how the CC works

 

Thanks! I'll report back once I talk to them about it. It will be a while, maybe a week or two. I really hope it works so I can take advantage of UpRev's MAP switching.

 

you overlooked the last item in the "input/output signal chart" (see attached)... also, for those that have had problems - as I mentioned earlier, there's isnt anything definitive (that I had read) to unequivocally confirm the gears are what caused cc issues - fd may have caused cc issues, but also could have been other issues (as indicated in attached pdf).

As for Canadian's problem... it could be confusion with clutch/neutral - but also a consideration that his ECM is designed to read signal from TCM... since has has no TCM any longer, that could be the issue (as he initially speculated).

 

Back a long time ago when we discussed this issue I read in the FSM that the TCM speed sensor compares with wheel sensor. If they are off more than a given amount then it disables the CC. This information is in that long thread that has been posted in here already.

The reason that CC works for OCG35 and some other people is because of the TCM changes in 2004.5. People that are 2003-2004 have the issues that 2004.5+ people should not.

There obviously are other factors that can disable CC but function should remain given TIRE SIZE is similar to stock up to ~80-84 MPH with the 3.5 FD and ~75-78 with the 3.69 FD.

When i first installed the 3.5 I could hold up to 85 MPH with the CC. As my tires are wearing down and in need of replacement now, I can only hold CC around 82-83 MPH.
