Bd Rad ????????

[Warpig]

Anyone else have this problem: From a dead stop I nail it. 1st gear no problem, 2nd gear no problem until I hit max rpm and defuel. It is a hesitation for a split, I mean split second. 3rd gear no problem cause rpm's are higher. I think I may need a BD RAD or something that eleminates max rpm defueling. What are your thoughts for those that know what I'm talking about. I should mention that I have 410's in the rear.

Can't you change your de-fuel with the FMS???

[Warpig]

Yes, EGT defuel only. I have that set to unlimited or off. This is a RPM problem in 2nd gear. Remind me on Friday if we both make it to Derby (by the way what happened last Fri?) and I'll give ya a spin.

Ughhh, things at home...

What are you hitting for RPM's? I can kinda get the same thing your explaining around 3200...

That's a good question because I need to watch the road under the circumstances if ya know what I mean. I am hitting the redline on the tach when I glance at it. I just want more, so the truck does not stumble under WOT in 2nd gear. I imagine it is not very good for the tranny also. It's gotta kill a good second or so in the 1/4 mile too. I think the BD RAD addresses this issue for those of us with torque mangement. I would be interested in other options.

Maybe I need to adjust shift points??????

Hey Jim, this is a serious thread!!!!!! :duh:

[Jim]

I was serious, but back on topic!!

[Jim]

anyway BD has a forum you can ask questions on, http://bd-power.com/forum/index.php?s= somehow I think there opinion on a product may be slighted though

[John DiMartino]

Mines never done that,neither has my Dad's 01.Did it always do this or just start?What is your fuel press when its doing it,also RPM when ti does it.The defueling problem is primarliy below 15 mph,your 2-3 shift,even with 4.10s should be at 45+mph,shouldn't be an issue by then.

Hey Tim,
I dont know if you've considered this or if this would help any.... But what about an ADD(Anti Defueling Device) from haisley machine? :dunno:

correct me if im wrong but i thought smarty did away with torque managment?!???

[Warpig]

SMARTY is suppose to help with torque management and raise the rpm defuel point. My truck did the 2nd gear defuel the last time you and Eli were in my truck. It's not easy looking at the tach when you are slamming 2nd gear and the truck is sideways. I'll get to the bottom of this soon.

Stop trying to Piss-Off the Duramax guys... :exactly:

Tim,


Could it just be your Converter UNLOCKING @ WOT?

I know that when I switch off my Smart controller it will do the same. When it is switched on I have the gain turned up to max so the converter CANNOT NO WAY NO HOW UH UH Unlock @ WOT.


(Just a thinkin')

That could be Tim, it happens for a millisecond (if there is such a word). I spoke to a friend of mine today who has an 01 that does the same thing. He uses a BD RAD when he is playin, and all is well. I think I just hit the rpm defuel limit in second gear. I need a smart controller anyways, so I will start with that. Oh, and while I got ya here: YOUR FORUMS MODERATOR IS STIRRING THE POT!!!!!!!

:falldownlaugh: :smilielol: Aww For Chrissake At least SOMEONE is gettig some work done 'round here LOL. Once we figure out the Kid's routine I'll be back to help stirr it up too :idea: don't ya worry :exactly:

[Warpig]

Well, I just want ya to know that I have Todd watching my back :poke: Us blue guys gotta stick together. Glad things are looking good with Ashlyn!!!!

[TORQUE THIS]

I've seen black pigs, but a blue pig :dunno:

Porkchop... I just figured you were giving the "other" guys a hard time again... Geez, lighten up... :wtf2:

[Warpig]

I am nutural :smilielol: Matter of fact, I just may trade my dodge in for a new chebby :exactly: :umno: But anyways Mark, you threw me for a loop because that happened last fall, and I've been playin nice with the chebby guys. Lighten up?? I am light, I just make you think I'm pissed off. Why do you think TMTT calls me MR. Cranky Pants?? :exactly:

[TORQUE THIS]

OK, enough of this BS... back on topic... :popc1:

Is your FMS set on kill when this is happening?

Does it do it on other settings? FMS or Smarty??

[Warpig]

No, no and no, it happens whenever I mash it WOT for a good distance. Funny thing: I posted my prob. on the BD Forum asking about the RAD. The RAD is only for 1st and 2nd gear anti defueling. A guy at BD responded saying torque management should not be an issue in 2nd gear. What I'm saying is that I hit the rpm limit in 2nd gear (i believe) a quick defuel, then back, then a quick shift to 3rd.

How about some 3.73s instead of tow truck gears? :falldownlaugh: :stirthepot:

Ya, I suppose you want to trade out of the goodness of your heart :smilielol:

[Aweik02]

Ive got 3.55s...theres no way i can let you cruise at 150 in OD. And me be wide open at 75 in 6th.

[Warpig]

:dunno::dunno: I dunno what u r saying?????

[John DiMartino]

I can get 114 mph out of my truck with 4.10 and 285 tires.It did 111 mph and change in the 1/4 mi.
Autos have .69 OD ratio,the 6 speed have a .73 or so.doesnt sound like a big difference,but it is. I run about 2000RPM at 70 mph with my 4.10's,my buddies 6 speed 3.55 run 1950 RPM at 70 mph, not a big difference.
