Sc400 Tach issue 2jzgte swaped..
#18
quick question, my tach is off also after my GTE swap into a SC400. obviously the mod wont work, but i do notice that the tach is not always off 1k rpm. my idle is pretty close to being right. at 3k rpm on my AEM it shows 4100 rpm on my tach, and at 5k rpm on the AEM it shows 6500 rpm on my tach. has anyone else not had a linear rpm error on their tach?

by chance do you know which model you boughtfrom dakota digital and how it was hooked up? im thinking of pickin one up so im not freaking out everytime im at WOT. having no idea what the RPM is worries me... and im getting tired of having to carry my laptop all the time to see what the rpms are....

Have you considered that your tach may not be working correctly.....i.e the motor may be going bad
Ever since I did the swap my MPH gauge stopped working....I have tried multiple things but at this point im looking into custom speedhut gauge set....
F the factory cluster.....they are garbage

The 1UZ give the tach signal as if the car were a 4 cylinder. MK3 guys can get around this by using a tach driver from an 86-89 Celica for their swap.
Not so much for the SC400 though. You will need to source the aforementioned tach adapter.
