Motec M4-8 9502 006 EPS B2

Postby Doug-WG on Mon Apr 12, 2021 4:46 pm

Hi all, I have a very old Motec M4-8 Serial number 9502 006 EPS B2 that I have had for many years.
It is installed in a project car that I have been working on and off for the past 15 years, vehicle has a twin turbo V8

I also have a Motec IEX Ignition Expander Serial number 0623 EPS 0010 and 2 x M & W Inductive Ignition Modules

I am now back doing the wiring and obviously will need to program the Motec
Unit is in great condition but I have upgraded computers and laptops several times and now I have relized I no longer have the software files nor the serial cable

Does anyone have appropriate files and/or perhaps know where I can source a serial cable??

I also assume that the software will need to run on an older version of windows, please advise XP or whatever ?

Regards Doug

Looks like you want the M48 EMP software that you can download from latest releases:

https://www.motec.com.au/software/latestreleases/

It indicates it will run on Windows 7 32-bit and earlier. I know I've used it with a USB Serial adapter with M48s in the past.

To communicate with the M48 you will need to use a laptop with Windows 7 (32 bit) or earlier installed, and you will also need the PCI cable to connect the laptop to the M48. The part number for the PCI cable is 63003 for the 2m long cable, and 63004 for the 6m long cable. These can be ordered through an approved MoTeC Dealer.

Hi, and thanks for the responses, PLEASE NOTE however my unit is a very old Motec M4-8 Serial number 9502 006 EPS B2, not an M4 nor a M48, it was built I assume 2003-2004???

I have attached a pic for reference

Very happy if current M48 software works but I doubt it

Regards Doug

M4-8 & M48 are the same device.

You just need to download 6.2 M48 software connect to the ECU via the MoTeC PCI cable and it will tell you what version is in the ECU if there is a mismatch.

Cheers, really appreicated. I have asked MPC for a price on the cable, so once sorted will just need to finish off the wiring etc :) Regards Doug
