write-up for socketing an ECU

[definitiveno]

I want to order my dsmlink already but haven't found any detailed description of how to socket my ecu. Has any one done a write up on this yet? Searching didn't get very far, sorry.......


I work for a video surveilance company and my boss being a master with electronics will be there for any help if I need it. I trust we could get it done without instruction but I'd rather know for sure we are doing every thing correctly.



Thanks,
defno.

If he is a master with electronics and soildering boards etc, it should be a "no brainer" for him. Look on www.vfaq.com I think there is something linking the TMO website.

Yes, when every one goes home he will sit for hours behind his big magnafine glass sodering circuits for his searver centers.


I didn't find any thing for ecu socketing on VFAQ, was it under electronics?


Sorry if I missed it......

A VFAQ is not needed, you either know how to do this or you shouldn't be doing it. The important information isn't going to come across in a VFAQ so we'd be looking at something like, Here's a picture of the ECU. Remove this chip, Install this socket, hope it works.

If your not experenced in desoldering and don't have a anti-static temp controlled iron the odds are your going to burn a few traces off the PCB possibly ruining a $200-$300 ECU when you could have spent $30-$50 to have it done correctly. The solder pads and circuit traces on a 2G ECU are easy to destroy if you use a little too much heat.

Your Boss should be able to identify the EPROM on sight and know how to desolder it. Just make sure you get a machine pin socket, not some cheap radio shack socket if you want the EPROM to stay in the socket over time.

I need to get my ECU socketed.

Weres the best/cheapest place to get it done?

steve, it sounds like you think it's about not wanting to spend 30 - 50 bucks, it's the 4 days of ground shipping there, the two days it takes for them to socket, the sunday that they dont do shipping on and the four days ground shipping return. I guess the other alternative is to pay 1oo bucks for next day shipping there and back and still only be down 3-4 days at best. I am not aware of any shops that do socketing/porting in the So cal area to have it done professionally so...... looks like i'll buy the boss a six pack and only be down for a couple hours.

I understand the time issue and I apologise for pulling the soapbox out in your thread.
The point is whoever you choose to socket your ECU shouldn't need a VFAQ on how to do it and having one would just tempt people to get in way over their heads.

I'll be happy to answer any questions your boss might have. Just email me.

Steve's right - either you know what to do or you don't. It's pretty straightforward if you know anything about electronics.

I see, thank you for the offer.


I think i only have a few basic questions to ask before we get started. I simply don't know where on the ecu the chip is located......once i have the unit out of the car will it be exposed or underneath some paneling......is there any thing different about the new one (ie....wires hanging out for the lap top) ........ I guess I will just get the ecu out and go from there but it would be nice if i had some basic idea of how it works before i get neck deep into the project. I appreciate your concearns as well, the only reason i have considered this is because my boss is very educated and experienced with electronics, iods, resistors, capacitors............

I will ask him if he has a anti-static temp controlled gun and wont consider having him do this without all the proper tools. Being uneducated in this department I was going to depend on the write-up to explain what exactly it was i needed him to do. I will E-mail ya if we get stuck, thanks again steve.

Sorry to hijack your thread.........


I need to send my ECU off to get socketed were can I send it to have this done?

I hear this guy does really good work.

 

[steve]

Dave Mertz of DSMlink does great work as does Jose Estrada @ Jester Tuning, and Andre Santos @ PINA Motorsports. I can't comment on the other guy

The EPROM is the rectangular chip in the upper left corner with the EB23 label. The chip below it is the CPU.

You must be logged in to view this image or video.

Is there any thing different about the new one (ie....wires hanging out for the lap top)

Nope, nothing external to make you aware that it's different. The 2G DSMlink uses the OBD II connector with a special interface module that converts to serial so your PC or Palm can talk to the new software. It also continues to talk OBD II for when you have to go into the shop or for emmisions testing

I will ask him if he has a anti-static temp controlled gun

Soldering iron, soldering guns are higher wattage tools not suited for most electronic repair. I only use mine to unsolder the screws holding the heatsinks on 1G ECUs and for splicing wiring harneses and such. Places that do a lot of board rework will have expensive hot air rework tools and specialized vacuum desoldering equipment.
