DIY: TACH INSTALLATION INSTRUCTIONS - Toyota Yaris Forums

frownonfun · 02-11-2009, 09:39 PM

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?
