I finally decided to buy an ECU for my Pinz, first to monitor its advance and exhaust gas,
then when everything is stable i will drive the advance with it instead of my distributor,
maybe one day upgrade to EFI but that's not sure yet,
I bought this gear from
https://www.diyautotune.com/product/ms3 ... w-harness/
MS3Pro Mini Standalone Engine Management System w/ Harness
Crankshaft / Camshaft Position Sensor - Hall Effect tab mount
Innovate LC-2 Digital Wideband Controller with Sensor - 38770
GM IAT Sensor with open element & pigtail
GM Closed Element CLT/Oil Temperature Sensor with Pigtail
I still need to order the smart coil module:

I installed it today and connected it to my laptop,
the only data i have for now is Manifold Air Pressure, as can be seen in below video,
I will install a trigger wheel on the crankshaft pulley, wideband O2 sensor and temp sensor.
I intended to buy the Speeduino initially but it was either out of stock or the shop did not reply to my mails,
Carl at diyautotune was pretty good to reply to my questions,

Installed the O2 sensor and the 36/1 toothed wheel this long week-end
With the O2 sensor, already saw that my idle fuel mixture was too rich, so adjusted the carbs live with the O2 sensor, no more guessing for me.

Yes good question,
On the green circle below.
Right on top of that pipe, 12 o'clock,
Had to be at least 60cm away from engine exit.
And this way I measure the combustion of both carbs.
Had to remove the exhaust between the engine and the heat exchanger to weld the bung, a bit of a pain.
