Long time lurker, first time poster.

I just acquired a truck from an auction and the former owner might even be part of this forum so if you recognize it, say hi! (or not.. it was repo'ed)

I am trying to figure which brand of turbo kit this truck has on it. It's not a CX racing or On3 from what I've been told so far. I does have an On3 turbo installed on it but On3 verified that the hot side piping is not theirs.
I haven't seen anything on the internet that matches it. The headers both output down towards the bellhousing and route back to an up-pipe on the passenger side.

Add-ons I've seen so far:

• Higher flow injectors with fuel rail spacer
• 4l80E trans
• Methanol injection system
• Wideband 02 sensor

It has been converted to speed density as the connector for the MAF has been hidden. I understand the entire cold side of the turbo is absent and will be replaced in the near future.

Also, I've been perusing the internet looking for a way to identify what type of programming has been flashed to the pcm. I do have a few OBD2 scanners but is there a PCM calibration ID that gives away whose product has been uploaded?

 

That looks like a custom job of some sorts. I've never see any kit made anything like that.

As far as the tune, you'll need someone with HP Tuners or EFILive to read it out (if it's not lock) to be able to know how it's setup. A regular scanner really won't tell you much.

 

Thanks! I was leaning towards it being custom but it has v-band clamp connections and decent fab work. The welds don't look like they were made with a welder from Harbor Freight!

I'll post up in another thread if someone in the Chicago burbs has a EFIlive tuner or HP unit I could borrow for a small fee. *read beer*

 

Can I clean slate this pcm and start over with the factory tune? Or can EFIlive overwrite everything even if it is locked\unknown tune?

 

Locked is gonna be very difficult to deal with. If it has an unlocked tune you can simply have it retuned.

 

The pics are not working

 

sir maybe u will find ur answer here :

unlockking a locked pcm who can do it
