Looking for input on the BD antidefueling module

[Huff N Puff]

Here is my understanding of how the defueling module adds power. The engine PCM actually has a defueling program,that protects the trans by simultanuosly defueling at shift points. The module by passes this protection. Will I grenade the trans bypassing this program. BD advertises it is actually better for the trans. Some claims have been . 5sec dropped from 1\4mile times using this module. Looking for any input from folks using the BD antidefueling module. Merv

Huff N Puff,



What the Race Anti-Defueler or RAD is designed to do is to prevent the torque management system from defueling the truck on the 1-2 shift. If your transmission is built to be able to take the kind of hp your truck is putting out then the transmission isnt going to be an issue. The computer doesnt like to see 15-20psi of boost and no speed through the vehicle speed sensor. It thinks that something is wrong. The only time that this would happen is in a drag racing type setting. Meaning you are powerbraking the truck, building boost before you launch. Then when you launch the truck it falls on its face before it will shift into second and take off again. That is what the RAD will prevent. It also takes the top end speed limiter out. If you arent racing your truck or launching it really hard, you most likely wont gain anything from it. If you have any questions feel free to give me a call.

Merv,



I have the box on my truck. I haven't heard of any gains of 1/2 second, but my truck did gain almost . 2 from the box.



The box doesn't actually add any power to your truck, it just allows you to use the power your already making, by not allowing the truck to defuel in 1st or 2nd gear.



Maybe I am wrong, but I don't rememebr your truck having the defuleing problem, unless you have you gotten it since you went to twins. I believe that the majority of the trucks that have this are the 2001. 5's. The last time I saw you run at MIR, I didn't see it defuel.

When your truck is doing what the RAD fixes you will definately know it. You are going to see you tach jumping around almost a couple of hundred rpm before you launch. Then when you launch the truck it will fall on its face before it shifts 1-2.
