I think, problem with cpu connection or cpu suply.

[CPT]

Use 12V external power suply for your unit.
Dont forget about cpt pin9 - connect to gnd in your unit

Hi

Power is fine direct on capasitor in PCB for for 3.3v supply from external PSU.
Also Pin 9 is at gound at same capasitor and CPT unit has it external supply so should be very fine.

I wounder if could be noice related or related to lenght af my wires.

[pnj]

Have dobble cheked wires, made then shorter still best I get is this wrong ID
Can it be unsupported ID you think ?

[CPT]

Really dont know how can I help you.
Programmer have support this cpu. ID Code correct.
I think you have problem with connection or power suplay
If you need , I can check your cpt programmer in my company office.
Delivery details you can find on my shop.
Please send programmer and add some info on paper about problem.
