Hey does anyone else experience your throttle just become non responsive during hard turns? I've been pointing fingers at the VDC but I also have the 7speed...

Do 6speed owners have this issue as well? if not, I'm going to look into TCM programming... ha ha

 

If I have the VDC on and the Slip light comes on; throttle response is diminished.

 

Yeah its the VDC limiting the throttle. Try it with VDC off.

 

Nope...no problems whatsoever in turns (or any other time for that matter). I've got the 6MT if it matters.

 

100% VDC. That's part of its job.

 

yep happened to me once now i turn the thing off all the time.

 

It also has to do with the 7AT and issues it has gear-searching around the speed a lot of turns are taken at. You basically have this moment where you lose almost all torque.

Unless your VDC light is coming on, it's probably just the 7AT.

Yeah, I learned this lesson about a week after I got my first G in 2004. Heading towards the freeway, light about to turn, so I put the hammer down. Make the left turn, hard, and she lets loose a little... I figure... screw it, I'ma drift right through this turn... not.

Throttle response went to nothing and the car slowed itself until it got a grip again and then the throttle came back. I was bummed, but impressed.

I leave it on.

 

I've found that I can lessen the amount of lag by stomping the pedal almost to the floor, then easing it back to where I'd normally expect to have it.

For some reason this makes it avoid searching as much and just lock in on the gear it should. Which is another reason I feel like this could be fixed with ECU/TCM programming, yet I fail to understand why Infiniti fails to acknowledge it...

 

You have to differentiate between the lag from the auto searching for the right gear and the VDC keeping a driver from doing a 180 on an entrance ramp.

 

really? I can slam the throttle in a straight light and get like a half second lag until it takes off like a bat out of hell.

I've noticed that with the VDC off the drop is less... but definitely not gone... I wonder if GTM's TCU tune can address this... I'd be willing to spend the $600 to get this damn transmission to behave...

 

I've noticed a similar problem. In manual mode (VDC off), slow down for a hard right and drop the gear down to 2 while turning and push the gas. The car will go into limbo for what seems an eternity until it finally dumps into gear (no slip light because the car has no power at the time). I can almost replicate this at will. I took it to my local Infiniti service center and they had no issue replicating the problem after I took them for a ride and showed them. Unfortunately, there is no fix. They supposedly reported it to Infiniti but seeing as how I have the 5AT there won't be anything coming down the pipe for it.

It's similar to the gear hunting you run across when slamming the throttle, then get off it when it starts to downshift, then slamming the throttle again. Car can't make up its mind what gear to be in and it just thinks about it for a while.

 

my 7at seems to work fine no issues yet

 

IMO, If you know your car then the lag is irrelevant. It took a little getting used to, but after driving this car for 10 months I hardly even notice the lag because I'm pretty much in tune with the car now. I know exactly when the gears will up/down shift. And now that the car has 15k+ miles the gear hunting is pretty much gone. And no I've never gotten a transmission tsb done on my car.

 

exactly! j +1
