With the amount on Mines chips coming in on imported cars does anyone know how to access/read the map on the chip as Mines themselves see reluctant to give out any info.

yep

2 ways

1. If it's a standard type adaptor board then just pull the chips from the sockets (if socketed) and read them out, merge them (if an ODD/EVEN Split)and decode them

2. If it's what looks like a chip, but is infact plastic with smaller devices encapsulated underneath it. Then you need to read it out from the car diagnostics port using bespoke S/W. A standard EEPROM programmer wouldn't be able to read out the data as it would not recognise the device.

Forgive my ignorance but

1:what do you mean by 'read them out, merge them (if an ODD/EVEN Split)and decode them'

2:What is a bespoke S/W

What equipment would be needed to do the above solutions?

Thanks

Is anyone actually running an early (pre-96) wrx with a Mines Ecu?

To read them out is to basically hook the chip upto a reader and then just do a dump of the chips contents.
Sometimes there may be 2 chips, one which contains the even address and one which contains the odd address, so what you would do to read them is get the contents from one chip (this could have the even addresses on it) and then read the contents of the other chip (containing the odd addresses). Once you have this merge the 2 outputs to get the 1 file which should be the map.

I imagine bespoke S/W is software. This is just custom written software that understands what is being outputted from the ecu

I'm guessing if the mines chip is like number 2 i won't be able to read it as i will need the Mines software.

yep, pretty much so. May need special hardware as well (dong/cable etc)

Jay,

cheers for explaining........

The Software needs to send the correct commands to the ECU via a RS232-TTL level converter.
This reads each byte out individually via a very slow baud rate (transfer rate).
The end result is the ECU code which is the entire code not just the maps (although you can read out the maps on their own if you know their address locations).

I say send the ECU down and I would offer to do it, if I still had a Pre96 car to plug it into.
But I don't, so I can't

It can be done on the bench with a suitable loom though !!

Check whats in the ECU first and maybe put up a piccie.

Cheers guys haven't seen the ecu yet (i do know it does work ok as it had a power run last weekend as was fine).
I may resurrect this thread when i get a more info.I've got a 93 wrx (ecu is in a 95 wrx) so is it possible for you to check in a day Scott it won't be for a couple of months but it would be nice to keep my options open if i do decide to use it.

Thanks again guys

Mine blew up with the mines. make sure it's mapped for uk fuel. in mine, it was a soldered in chip to the main board with J1 cut, so hard to pull out and re write, unless you had the loom
