Where are you getting the manual to read what the codes are? I am hoping to have a tuner in the next few weeks, and would like to know how to read them. Also To go back to the factory tune do you just unhook the battery and reload the factory tune. And does this then clear any evidence that a custom tune was in the computer? Sorry for hijacking the thread I just did not want to start another.

most of the codes will say what is is on the diablo hand held tuner.
some up have to look up online. you dont have to re-set the battery
it just makes sure the computer does not remember the code.

Everything fine, not tune related. Idle rpm was too low!

Hopefully your SCT will have a manual with the codes in it, my Diablo did, along with all the datalogging parameters and what they are.

Actually the Powertrain Control / Emissions Diagonsis Manual says P2122 is the Accelerator Pedal Position (APP) Sensor Circuit 1 Low Input code. So I assume the APP sensor is on the accelerator pedal itself , as opposed to the TP sensor being on the throttle body :scratch: ...
Got my info from the Diablosport website.

Now that I am home (takes a sip of a cold beer) I can eloborate more.

It turns out that the tune had the idle rpm set a little low, and on the downstroke of the rpms they fell too low and threw the code.

Reloaded tune, set idle rpm back up a little and good as new. Thank you all for you suggestions and help.

Well, don't get too "elaborated" and try to drive j/k




Good to see your back in the saddle again and that it was just a
minor adjustment.

Ah, you finally took the right approach. When all else fails, have a beer. If that doesn't work, have another. Eventually you will no longer have the problem, or remember what it was to begin with

Last night after the issue I sucked down some serious wine, and I was wondering why does this always happen to me.
