Is anyone able to point me to an explanation on an EE level of how the Delco operates in lhm (with the programming of the resnet in the memcal ) electrically please?
Yes, I understand it kicks in when the MCU is dead...
And yes I understand 'its the resnet'
Thanks.

Re: how LHM EXACTLY works ?
I think your looking for more detail but i think the resisors work with a basic analog timing circuit to open the injectors for a certain time per reference signal. Spark timing isnt running so static 10 degrees is provided by the ignition module. This gives fuel and spark to make it run, but thats about it. Ultra basic. Limp home, only.
