TRNW-2: OBDSTAR 706 Cloning

[Fred Whitaker]

  Thanks for the replies guys.  I will order one tomorrow.  I will then have even more messes to get into LOL.
 Fact is though I have needed something like this for quite a while!

We have the dc706 as well. My experience mirrors Dan’s. I ran the provided connection hardware for a while, recently bought the big set of tcm connectors they sell.

While you brought this topic up, I'd also recommend looking at PCMFlash.  I got my setup going here about two years ago and have been adding some support recently.

PCMFlash fills some gaps in the DC706 coverage.   My experience has been with RE5 / RE7 clone support and some oddball Hyundai PCMs (which control the trans in some models).

I had a old Hyundai Azera (Toyota Avalon clone lol) which had Delphi MT38 PCM with some strange complaints.  Came in with a intermittent Line pressure solenoid code, but then momentary EFI shutdown at times.  Very difficult to duplicate.  New and refurbed PCMs were outside the customer's budget, like $2k just for the box.  Used PCMs were dirt cheap, but can't be used conventionally due to immobilizer hardware present.  PCMFlash saved the day here and was able to do a direct clone of the old PCM and write over a used PCM.  Worked great and fixed the concern for a fraction of the cost.

PCMFlash is a software solution requiring a Windows laptop, supported J2534 passthrough, and the usual bench toolings.  He's got good support across a lot of modules and responds to questions quickly.

I'd not recommend PCMFlash as a first tool, but you're going to find one solution will not do it all.

  I have been leaning on the shop owner pretty hard to get one of these for cloning. Friday he pulled out his credit card and said "order one". I backed up so I could look at the different options. I figure on getting one with the MP001 programmer. From what I read it's the latest and greatest attachment. I know at least a couple folks on here have one. Just thought I would ask if anyone regrets buying one or any advice.
 TIA...... Fred
