Title: Dedicated bench port so you can leave the ECU in the car and still bench flash Post by: ericpaulyoung on September 25, 2014, 11:51:56 AM I could not find any posts on this, but it may be an obvious thing that I am misunderstanding. If this is better posted in the newbe section, just let me know.
OK, so I am new to the bench flashing, and would like to make it quicker to flash the car then go for a drive. Is it possible for me to pull my ECU and solder a 12 pin connector to the pads used to BDM? Then just put a rubber gland seal on the wires coming out of the ECU plastic box so that water cannot get it. The plan would be to reinstall it in the car, and when I need to BDM, I would just disconnect the car battery so that the ECU is powered only by the CMD box, and I can just BDM the ECU sitting in the car as if it was sitting on a bench. epy Title: Re: Dedicated bench port so you can leave the ECU in the car and still bench flash Post by: smelly240 on October 02, 2014, 07:13:07 AM What kind of cable are u using for flashing through obd port? Or are you just bdm?

Would an emulator allow the same level of direct access to the chips? epy Title: Re: Dedicated bench port so you can leave the ECU in the car and still bench flash Post by: ericpaulyoung on October 18, 2014, 12:19:00 AM OK. Here is my first attempt. I must say that soldering on the circuit board is tougher than I expected and I lifted a couple of traces which made it a bitch to get it soldered back on. But in the end it works fine. I will do my other ECU the same way but with a longer lead. Now I just connect directly to the BDM100 without a rack or anything, and I can leave the little connector in the engine compartment and BDM flash without taking out the ECU anymore.
I just used some 10 wire flat cable with a 10 pin 2x5. :) (http://i1073.photobucket.com/albums/w381/ericpaulyoung/6D057E31-A613-4028-BDD7-E5CEB1EEC0C2_zps7cjut8rr.jpg) (http://s1073.photobucket.com/user/ericpaulyoung/media/6D057E31-A613-4028-BDD7-E5CEB1EEC0C2_zps7cjut8rr.jpg.html) Title: Re: Dedicated bench port so you can leave the ECU in the car and still bench flash Post by: ddillenger on October 18, 2014, 12:49:58 AM Next time I suggest soldering a header to the board. Then plug the cable into that. Much easier to deal with :)
As for lifting pads, lower your heat. Title: Re: Dedicated bench port so you can leave the ECU in the car and still bench flash Post by: 99pwr on October 18, 2014, 01:12:41 AM I do not suggest you to use long cables, you have electrical interferences and the car will not go well.

Good info. I was planning on having a long lead going into the cabin so I can just plug in from inside the car. But I will probably just go back to the idea of having a short pigtail in the ECU area. epy Title: Re: Dedicated bench port so you can leave the ECU in the car and still bench flash Post by: ericpaulyoung on October 18, 2014, 01:37:51 AM Here is the second ECU. It came out a lot better after my practice round on the first ECU. I just cut a slot in the case that I will silicone shut, and not I never have to pull the ECU again (hopefully).

I am really slow. I totally missed what you meant by emulator. I will go check it out. If you have a link to a good starting point, it would be great. Thanks EPY Title: Re: Dedicated bench port so you can leave the ECU in the car and still bench flash Post by: ddillenger on October 18, 2014, 02:14:38 PM I am really slow.

Thanks EPY When nye speaks, assume it's ME7 based :P There is no economical emulation for MED9. Title: Re: Dedicated bench port so you can leave the ECU in the car and still bench flash Post by: ericpaulyoung on October 18, 2014, 02:19:32 PM I guess my emulation will be driving the car and pulling over to BDM a change.

med9 can easily be flashed over obd, is quite stable, and if bad flashed, just reflash over obd again. Title: Re: Dedicated bench port so you can leave the ECU in the car and still bench flash Post by: ericpaulyoung on October 18, 2014, 02:40:57 PM Mostly just to try something new. But also because it is a lot faster. Flashing OBD by Maestro takes 15 minutes. BDN should be more like 1 or 2 minutes. That is a huge difference.
EPY Title: Re: Dedicated bench port so you can leave the ECU in the car and still bench flash Post by: ericpaulyoung on October 18, 2014, 02:43:14 PM Plus it should be more stable. What I mean us using clone OBD hardware is not always very consistent. But I don't read any issues with BDM100 under XP. So I should be better off this way.
EPY Title: Re: Dedicated bench port so you can leave the ECU in the car and still bench flash Post by: k0mpresd on October 18, 2014, 02:46:01 PM whatever makes you happy i guess.
Title: Re: Dedicated bench port so you can leave the ECU in the car and still bench flash Post by: ericpaulyoung on October 18, 2014, 02:58:51 PM Not really trying to be different just for fun, just trying to have a faster way to flash. I usually try a handful of variations and is I can cut reduce the time, why not? My question for you is, if you could reduce the time to flash from 15 minutes down to 2, and also make it so I do t have to buy more hardware, and also be more stable, then why wouldn't you? I am confused why anyone would see a faster, cheaper, more stable way to flash as a bad thing??

You should epoxy over where the wires are soldered to the BDM port if you haven't already. Much more resilient that way.
Title: Re: Dedicated bench port so you can leave the ECU in the car and still bench flash Post by: ericpaulyoung on October 18, 2014, 04:17:52 PM Good idea! I will throw some sealant over it.
Title: Re: Dedicated bench port so you can leave the ECU in the car and still bench flash Post by: ericpaulyoung on October 18, 2014, 06:34:04 PM Well I just checked it out and there is some bad news. The BDM ports do not work with the ECU harness plugged in. So you still have to crack open the ECU box and disconnect it before using BDM. I guess it makes sense, as the BDM ports were not designed to be used with the ECU installed. Interesting stuff.
epy Title: Re: Dedicated bench port so you can leave the ECU in the car and still bench flash Post by: ddillenger on October 18, 2014, 06:59:47 PM Consider scooping up an MPPS cable. They flash faster than Maestro at least.
Title: Re: Dedicated bench port so you can leave the ECU in the car and still bench flash Post by: k0mpresd on October 18, 2014, 07:36:29 PM i think we just went full circle here.
Title: Re: Dedicated bench port so you can leave the ECU in the car and still bench flash Post by: ericpaulyoung on October 18, 2014, 09:44:39 PM Yup, made a circle. Oh well, I had to at least try.
I bought a MPPS clone last year and it didn't work at all, so I kinda gave up on them. I guess I can go look for a higher quality clone. Do you have a recommendation? I am thinking about that guy in Europe, but he wants like $500 for his clone cable. Epy Title: Re: Dedicated bench port so you can leave the ECU in the car and still bench flash Post by: ericpaulyoung on October 19, 2014, 01:06:52 AM So I am trying to figure out if there is one or two wires that could be cut off that would allow the BDM to work while still connected to the rest of the harness. If so, I can just put a disconnect on those lines and flip it for when I want to do my in-car BDM flashing. I am thinking it would be one of the wires needed for bench flashing, but not sure. Any ideas?

Why don't you remove 12v and KL15 ( 12v ignition ) from BDM pad ?
Title: Re: Dedicated bench port so you can leave the ECU in the car and still bench flash Post by: Beaviz on August 16, 2017, 03:05:14 AM Did you ever get this to work? I am considering the same, since it would save me many hours waiting for the writing process doing MED9.
