I've got a video of whats happening to me I want to know is this problem from the tune or from the cam degreeing?



notice how the rpm reacts when I apply full throttle

 

I guess you need to explain a little better..........

 

When I go WOT see how the speedometer moves and how the RPM moves it moves fast then it slows then fast again then slows. notice at 5000 rpm how it stays there then it moves.

 

The tach starts to slow down as your speed increases because your aerodynamic loasess are increaseing exponentially. The rate at which your speedo increases also solows due to the same reason.

I dont see a problem there whatsoever.

Enjoy your truck.

so..is it like it bogging down?


everything in the vid looks normal to me

 

It is in the tune. Your ETC speed limit kicked in. It shut your throttle blade, then will report to send a command across the system bus to show vehicle overspeed on the dash and indicate a light.

 

Yes it bogs down.


And its not about the overspeed in the DIC

 

Who did your tuning?

 

I would do like jesse said and look through the tune.....

 

There is a setting that allows the ECM to be in control of the speed limit, OR another module. ON YOUR application it is set to OTHER module, so no matter what you set YOUR ECM values to it will still have a speed limit unless you turn it to be ECM in charge. I have tuned trucks with tvs2300 on them and a few with ecs supercharger kits where they have been all the way up to 162mph and it NEVER throws that light when you delete that other part. It is set to CUT THROTTLE not fuel or spark so that is why it is doing that.
