“PCB installed with no trouble, just had to relieve the inner radius a bit. I misunderstood how the switch works! Using your instructions, I found it works perfectly- thank you.”.”

“I received the parts yesterday, today had to buy a cutter for M2 thread, but the exchange of the print was quite easy to do. I just returne from a testdrive and the engine is running much smoother now. The pickup from idle speed is much better now. Thanks for your work on making this alternative print available !!!! My dad will be happy with this modification.”

“Hi Guido just back from a short testdrive with the new PCB installed, and there is a difference. The car feels more responsive when giving more gas/ rev. and also more stabil when idling. So overall it feels positive.”

“Hallo Guido, II had a hard time finding a M2 tap easily. I also had some anxiety about tapping such a fine thread in a thin metal. I found a piece of salder that had a slightly larger OD than hole ID. I worked it through till slightly higher than the PCB and then melted it top and bottom. I checked all the specs and when I installed it….what a difference…I actually have a smooth idle! Thanks for your help and those exquisite instructions.”
