I just found this thread guys trying to work out why my PET 2100 DXR tach is not working well. Im the same as the guy above. My tach is not reading properly. Most runs where Im at 7100 rpm is reads 2340 or some low number. 1 run out of about 6 gave me a true 7180 on my 07 GP1200. Same prob with my SXR 1200 most runs read real low RPM and wont go higher than 3000.1 time it gave me a true 7500. And I have it set to 23:46 correctly. anyone else had this issue and found a solution??. Tried it on cyl 1,2 and 3. Never on all 3 at once.
It always gave accurate readings on my 2 stroke 2 cyl race engines, just not the 3 cyl
