I forgot to keep you informed, but last year, I installed r34 coils, a do luck r34 harness, so I removed the amplifier, and changed the socket on the motor side. it works perfectly.
I remind you that my goal was simply to make it more reliable because I had micro cutouts, so my main goal was to remove the capricious element: the amplifier.
And also, I have a non-programmable mine’s ECU. if I had a link or haltech, I would have taken r35 or r8 coils.
