Hi,
My father in laws place is under offer and I have to shift the red and black Panhard. Unfortunately for me, the carburettor and ignition system (distributor and coil) were transferred to Brian Osbourne's 24CT to fix his engine issues years ago, and these components are missing, so I had to find replacements. I struggled to find a Weber DCNF for the bespoke manifold I used on Brian's and my car, but eventually a 42 DCNF surfaced from my collection. Unfortunately the push set up on the accelerator meant I had to reverse the carburettor through 180º and bastardise a Weber throttle linkage from a DCOE and Ducati Paso to effect a satisfactory pedal action.

The next stage is to restore the ignition system, and swap out the burned out commodo multifunction column stalk switch.
All the best
Mike
Hi again,
like I said the next phase was to sort the ignition and swap the defective commodo.
All the wires are black in this car, unlike my yellow and white 17BT mule, so I had to sequentially swap these over one at a time. Interesting the screws are not metric but UNC 4-40.

Anyway all swapped over, no main beam at the moment, but all other functions are working now.
All the best

Hi again,
Next up on the car was the ignition system... unfortunately for the purists I wanted to go electronic and programmable. Before Brian passed in December 2022, I did successfully programme an ignition unit to transform the throttle response and drivability when the Weber DCNF was fitted, which produced a very strong vacuum signal that overpowered the OEM vacuum capsule.
Recreating this using 5V TTL Toyota wasted spark coil using the same ignition unit was going to involve more work, as I didn't have a camshaft timing wheel trigger wheel and sensor in this engine. I decided to resurrect a distributor based missing tooth trigger wheel I developed years ago, but still use the Czech programmable ignition system I fitted to Brian's car aka IMFsoft ECU MasterLite.
I've built a bench rig, and hooked it up to an oscilloscope, and had to convert the 12V dwell switching signal into 5V square wave that can trigger the Toyota ignition coil, through 8-16V without damaging anything. I'd already made a PCB and populated it years ago to convert the non-contact cam lobe signal into something that would drive the programmable ignition, but the output was too high a voltage... so another PCB, a resistor and a Zener diode to the rescue and bingo.

Next up, I had to make a coil support bracket that would be in the middle of the engine to keep the HT leads the same length, but the bulkiness of this Toyota coil made the fitting harder than the Renault coil I had used previously.
All the best
