2004 Bonneville GXP....can we even tune them?

[GPGTP]

I don't see it under the supported vehicles. Is the simple answer "NO" we can't tune them?

[GPGTP]

I mean....nobody knows???

[Bill@HPTuners]

we'd need pics of the pcm to determine support.

[GPGTP]

I'm sorry I thought it was a straight forward thing, No?

2004 Pontiac Bonneville GXP.

[Bill@HPTuners]

I have no idea what pcm it has, it could be LS1, could be an early E40, could be some oddball northstar pcm(which is what I'm assuming it is which is not supported).

[GPGTP]

Are you are telling me that they came with several different PCM's for the 2004 year or that you just don't know what PCM came in them?

I wonder how I can find out.

It's an oddball Northstar PCM.

[Bill@HPTuners]

Yeah that one isnt' supported. E40, E38 & E67 all are. That one is none of those.

[GPGTP]

ok thanks guys. So does the 05 use a different one/ one we can tune?

[Bill@HPTuners]

Dunno, I'd need to see pics of the pcm, GM doesn't make that information easily attained.

[GPGTP]

I see, maybe someone can chime in.

[Bill@HPTuners]

Even if the 2005 uses a pcm we support, say E40, that doesn't mean it will be an easy swap into your vehicle and would likely be more hassle than its worth.

[GPGTP]

Oh.....no I was just asking about the 05 for future reference. I know a guy that has an 04 that wants me to tune his car.

This is coming from a guy who just found out his tuner will work for Fords. I thought they were completely different tuners, not just the credits.

P07 vs E67 (I think it was taken some time ago)

Any support for these yet?
