DIY: TACH INSTALLATION INSTRUCTIONS

[frownonfun]

hey so i have my tach installed but how can i be sure it is giving me the right reading? i hear people talk about hitting 2500rpms and up to like 5000rpms and this makes me wonder if something isn't hooked up right cause i am not getting anywhere near that on my tach. my engine sounds like it is going to explode at around 2600rpms so i really haven't gotten much higher than that. i just assumed 3000 was redline from the way it sounds when i rev that high.

any thoughts?

Has your Tach got pre set cycliders 2,4,6,8
if so set it too 2 and it will read properly.the yaris has twin coils
and you are only taking the reading from one of them.
