I posted photo's and a circuit diagram for a development memcal quite a while ago. Will have to try to find it. From memory, the extra chip was the knock filter. You can see extra resistors and capacitors on the board that are used to tune the filter, that are not included in a typical netres. Obvio...

Joining D9 and D10 enables the 'Peak and Hold' function of the driver for lower impedance TBI injectors.

Any left over buffing compound in the tin will high-flow the injectors too!

Plenty of Astron's had Bosch reluctor distributors that will work fine with the Camira module once you have locked the advance mechanism.

Do you see a corresponding spike on the B+ supply to the distributor sensors?

Idle can be difficult to setup on an engine dyno at times. Some of the Superflow water brake dyno's, depending on how they are plumbed (pressure fed as opposed to suction) can place significantly more load on the engine than normal idle situations would see. You could be chasing your tail trying to ...

Wrong ECU selected in WinALDL.
The data reported is not useful until this is corrected.

From the description, sounds like a dead ECU or ignition module.

TPS as load variable.
Great for big cam's and/or multiple throttle setups.

This document will give an idea of the complexity of the knock filter.

Must be making a mess of the pinion bearings if the crush tube is letting go!
