So how can i get rid of p0420 & p0430 codes

[06MonteSS]

you can't... would need to get a custom tune made for it in order to have the codes disabled....

which I could certainly do for you... but the issue may be that there are no template files yet for these G motor trucks, since they weren't supported, so diablo custom tuners like myself may have to wait until new template files are given to us that support and provide access to these G tune files... I will check with the guys tomorrow to find out if that's the case or not....

Cool i will wait for your feedback tomorrow
I downloaded my stock file in my computer and it's waiting for u

[06MonteSS]

were you able to select the 87 octane tune or Diablo Tune? or could you only do modify stock tune?

[qac]

I had two option diablo tune and modify stock tune
But i only tried the diablo tune

[06MonteSS]

nope, no custom tuning for the G trucks yet... have to wait for all new templates for the tuning software... so will be a while...

[qac]

ok

and i'm wandering does this update write other G motor truck ECM or only me

[bhulet]

So does this work for the G trucks or not?

[06MonteSS]

yes, it's for G trucks... but just be aware that your particular calibration ID may not be supported in it yet...

there are only a few supported calibration ID's in that update currently for G trucks... if yours is not supported when you go to tune your truck, it WILL allow your tool to read/save a copy of your original backup file, which you'll then need to post up there... and they'll add your calibration ID to a new update file if yours is not supported in that current update already...

[bhulet]

post up where? Sorry, may be a stupid question. I just expected to plug it in, and basically it do the rest.

[06MonteSS]

no, you need to manually update it with the test update file on the previous page

[bhulet]

Since we are pretty active at the moment here, Is there something available for the "g" trucks for the intune? I hope there will be an 87 octane tune (named ?) and the diablotune? Sorry for the misplacement of this ?

latest test version I posted is working with the G motors, we are making new tunes now.

As "luck" would have it my trinity was returned to me due to a crapped out pcm to start with for who I sold it to , but alas, the test tune posted doesnt work either for my 2012 just another failed cut

[06MonteSS]

did it save a copy of your original backup stock tune? you'd need to post that file up here so they can add support for your particular calibration ID of your G motor/ecm... this test update does not have ALL gm calibration ID's in it for G trucks... only has a few in it at this point... going to have to add additional calibration ID's to the update as they come across them.. which is why you'd need to post up your original backup stock tune file for them...
