05 P59 dbw os change

[Boostedforlife]

So read some where that I can't change the os of the p59 with out changing the tac and pedal.

1. Is this true?
2. If yes does anyone have a p59 with the iac drive, or can someone explain what I would need to do to go to the boosted custom os?

Not against going dbw and thought I grabbed a hdw and sn that had a iac driver but the list I looked at must of been wrong. It's an 05 pcm.

As far as I know the model year OS is tied to the model/year Tac module/pedal.

So if you have 2004 OS you need 2004 tac +pedal.

Tac-Pcm communcations is done on the Aldl line so hardware of pcm shouldn`t matter.

Thanks guys for the info.

I'm not afraid to wire in the pedal. No big deal there just know it will be run the boosted os 7603. So I'm not sure how to find the the right tac for this os
Guess I could cruise ebay for the hardware numbers gampy listed. But then again when I don't know I like to learn. I'll put the os off this pcm to start and go from there. I know this one was pulled from a 05 suburban.

What year is the 7603 os? 2004?

I think over on Gearhead I've seen it in a few years 2003 and 04. But could be wrong. Was on the p01 before so never paid much attention.

Edit: guessing it's an 04 os. Hoping it was a 04 pcm I'll find out tomorrow morning. Will make it easier

12587603 is from 2004, my records show it was never on that Hardware, nor was it used on a 05 Suburban ... They could be wrong!

Thanks gampy yeah my research came up with that as well. And good to know sbout the hardware number guess I'll be looking for a new pcm or a 04 tac/pedal.

[Gampy]

That hardware was used in 2005 and 2006 according to my records.

[Boostedforlife]

So just to clarify I need a 04 tac that was on a 7603 os to make the dbw to work or get a pcm with the iac driver(probably the easier of the two)

[Gampy]

Asking the wrong person ... I dislike fly by wire!

I prefer the instantaneous operation of a mechanical connection.

So, I would go DBC.

[Boostedforlife]

Lol me too. But it's bugging me that I don't so I'm trying to learn

Side note all my searching only has given me a year range of 03-05 no real way to tell the difference from year to year.
