    The ECM is out of an automatic you need to have the dealer flash the manual engine programming. It is probably the anti stall acting up.    If not verify that it came from a late model truck

I talked with one of them earlier and I guess they are slammed right now. If you submitted a ticket they will get back to you ASAP.

Finally got a call back from smarty Adam got me going again and got me an update really nice guy to deal with and seemed to really know what he was doing and was quick about fixing my issues once I got in touch with him

So I put the smarty on my truck at first start it has a rough high idle for about 10 seconds then drops back to a normal idle but when it drops back down my tachometer stops working and the truck has hardly any power and it’s making throw a code for the crank sensor wth happened my truck is useless this way

If not verify that it came from a late model truck. There's several articles around the crank/can/FCM all 3 must read the same or else you'll get issues.

 

 

May I ask how it died? Do you have a noise isolator on the truck? Was the the alternator tested?

I dont think smarty does any tranny changes other tha apps values.

 

Maybe crank sensor is bad??.

 

I'm very curious about ECM updates. 

 

Immediately assuming updates would be loaded on to smarty and then loaded onto ecm ?

 

The smarty doesn't change anything in the transmission programming in terms of shifting. It changes how the PCM and ECM communicate via the torque management settings.  

 

With an automatic it charges how much sooner the fueling comes in thought the ECM. This is often felt through the shift points changing based on the TM#. 

 

The shifting in the valve body is done either thought hydraulics or the electronics via the lock up and governor pressure solenoid.  Neither of which is controlled by the smarty.

 

However on manual trucks it doesn't show up because your brain does the shifting, not a computer/tv cable.
