Hello,

I am getting ready to order a Rogue A tune for my 86 951 and I am trying to decide if I want to do the DME conversion myself.

I found this very nice article:
http://www.the944.com/88_to_86.htm

However, I am a bit confused as if it is this simple.

It seems that I need to:

1) Add jumper
2) Add socket extension

Are there any other steps? It would seem that the new pins would be floating. Do I need to tie the top three pins (26,27,28) together to get voltage to the 28 pin DME? Are there other steps that need to be done?

I don't mind paying Josh to do it for me, but satisfaction comes from doing things myself. I just want to make sure I am doing things correctly.

Thanks for the advice.

What I got out of the write up is you're simply adding 4 new pins onto the motherboard which seems very simple, indeed.

Rogue_Ant

Yep, you need to add the 4pins to the DME EPROM socket. And the jumper located at B700.
And yes, 26, 27, 28 are all tied together.

Ok thanks Josh!

Where can I get the pins and jumper to do this myself? Radioshack?

Rogue_Ant

Chris, give me an email - I will send you the pins and jumper if you want to do the conversion.

ChrisLovin

Gee! I'm falling head over heels for this community. I knew before i started posting here how nice and helpful everyone was but i never really imagined such willingness. I can't wait to pay it forward someday.You have a pm Josh.

Got it - and returned.

Ask Joshua to be sure, but for the MAP sensor that comes with the M-Tune, there's a resistor that needs to be removed (or cut). I'm pretty sure that the A-Tune has the MAP as well.

As for the conversion, I found it to be very easy, but I did have some of the same question that you do. I don't know if I'm the best measure of it's difficulty though... I've had some experience with electronics.

Some basic soldering skills is all it takes. If you've ever fixed a cold solder joint on a broken piece of electronics then you can do this install.

ChrisLovin

I have never done that before, I'm sure I will have more questions when I receive the pins and jumper from Josh.

This is actually a pretty good tutorial... It's pretty thorough and easy to follow.


also, I know a lot of people are content with re-heating and re-using the solder that's already on the board, but I think it's a bit too risky. I would recommend picking up some solder wick and using it to remove the old solder at the points you'll be working with before adding the new components.

Here's a reasonably good video of how it's done:


and, lastly, if you're even sorta apprehensive of soldering on your DME ($$$), pick up a cheap generic circuit board like the one in the above video at Radio Shack or where ever and some resistors (which are very cheap) and practice soldering and de-soldering on that until you feel comfortable enough with it to commit.


If you have any questions or concerns or whatever, definitely ask before diving in. Soldering is really simple and easy once you know what you're doing, but it's definitely a skill that takes some learning. If you'd like, I'll PM you my phone # and you can call me.

See, Mom? I did something with my BSEE!

For what Joshua charges you for this, give it to him. Why waste the time when He has done many and you have done, none.

Hey Jos, how is married life. Car is in for paint now.
