Disable the anti stall feature on an 06 6 spd.

[DBoyd]

How do I disable the anti stall feature on an 06? It is the feature that automatically adds fuel when the engine is pulled down too far.

Thanks.

You can't.

Why would you want to disable it?

 

[Motorhead]

That is what diesels do. The fuel injection when at idle or just above wants to keep the RPM setting it is set at. I have tried to pull a full sized truck tractor at IDLE forward and forgot to release the air brakes. It over powered the brakes and moved forward... . AT IDLE.

I'll double down on that one. You are the first person I have heard of that apparently dislikes like the "No throttle launch/take-off".

 

[Regcabguy]

I first noticed it when new. I had it in 2nd,foot off the throttle and it speeded up to prevent bogging/stalling.

Go drive a 6-litre with a stick and you'll really appreciate this feature.

 

[DBoyd]

Thanks for the replies.

I figure it is another intrusion on driving the truck. I especially don't like it when slowing down for a railroad crossing and it decides we need to speed up. Wish it was like my 97 with no computers and 22 mpg.

clutch anyone?

Umm, the fix for that is push the pedal on the left in.

Seriously, if you are in gear and letting the rpms drop so far the truck is speeding up you have operator issues not computer issues. That is needlessly abusing the clutch, transmission, and engine.

Might want to rethink the driving style that is causing you concern.

I hate being the parrot on the shoulder that repeats everything, but both of these are the answer.

Alright, I'm moving along about 25 on a city street in third, I come to a crossing and I want to slow down to 20 or less and the danged thing won't allow it. So I have to clutch and downshift to second which is way too low????? Cmon folks, why don't I have to do that in the 97 with the 5 speed? About the same rear gears and all. Just more crap to put up with. Shoot, the 77 Chevy half ton with 4 speed is more driver friendly than the 06 with the robot on the fuel pedal.

You gotta be lugging engine down to 1000rpm to make this happen or your TPS is getting a little sketchy on the low side.



Don't have this issue with sig truck.

 

[DBoyd]

In looking at your sig truck, it has the NV5600 and my 06 has the Getrag(?). I wonder if the ratios are just enought different to cause the problem. And surely one could pull the engine down below 1000 on a temp basis with out harm. I had a 99 with the NV5600 and really enjoyed the setup. And hopefully the TPS isn't going bad with 8500 miles on the 06.

 

[cerberusiam]

Ratio differences between the NV and MB are neglible in most of the forward gears. What isn't neglible is hammering the DMF like that. Comparing what a 97 mechanical engine does to an electronic controlled one is not going work. The 12V's would let you do stuff that wasn't good but they were under powered enough they didn't hurt things. There are a lot of reasons why NOT to lug these engines down under 1500 rpms or so and not expect the ECU to try to recover.



If you want to slow down, clutch the truck and let it roll thru then engage again, problem solved. Trying to walk the brakes to slow it down when the rpms drop under 100 is just gonna activate an over ride. You just need to learn to drive around it.

It is very hard on the clutch to have it engaged like that.
Keep RPM above 1500 to smooth out the pulses.
If you continue you risk ripping the center out of the clutch.

It is also hard on the transmission gears AND bearings and bearing bores in the case. It chatters them.

 

[BGlidewell]

Whenever I drive a manual, the left foot almost always follows quickly behind the right. This is something I learned to do intuitively. If I can anticipate a prolonged clutch engagement sometimes it gets slipped into neutral to save the thrust washer and the bygod rod. I've seen others drive without clutching lugging the engine down and that always seemed weird to me.
