Lotus carlton ECU?

[Dave Evans]

Hi all

Can anyone help Identify this ECU, I believe it to be a GM-P4,
it's fitted to the Lotus Carlton in the UK and the Lotus Omega in
Europe, the number's on /in the unit are as follows:


OUTSIDE:
SERV. NO. 01228331        AWSX
867519  M011201519
16157519

BAR CODE THINGY
*867519M0XXXXXXXX*  /* XXX appears to be part of Vin Number*/

INSIDE:
Once the lid is off, the number 309033100260285 is printed on some kind
of shield inside the box.

The EPROM is held in a blue lidded carrier, and has DELCO AXSH 2423
printed on a label over its UV window. In the carrier is the 28 pin
EPROM, a thick film circuit of some kind (marked 1070033), and 2 IC's.
One is a 16 pin device with the number 16154201 printed on it, and the
other is a 14 pin device with the number 16150031 on it. all the devices
do straight to a 33*2 (i.e.  66 total) IDC type connector, which
connects to the motherboard.

The EPROM appears to be a National 27C256B



Also does anyone have a copy of the EPROM in the cartridge used by the
TECH1 for this car?
