Tachometer question
- Thread starter cooolkid
- Start date
Its not the ECU its the ignition system, coilpacks vs distributor...
You can swap a couple of resistors and make an NA tach work, or you can do what I did and swap in a turbo tach...
Minus the gauge cluster srews, the tach is held on by two screws and its all plug and play...

Then it probably wasn't a GTE tach to begin with... Check the resistors in it to see or measure it with a meter and compare tach readings. It should be a mile off even if it does move.
Anyway, here are the resistor values
bump from the dead.
Has anyone attempted this on a digital dash tach?
Swapping an awesomely built 7mge into a turbo shell with a factory digital dash and I need the tachometer to work to pass inspection.
Plus I love the digital dash to bits. It's like driving a s2k except better because it's a mk3 supra and not a honda.
I have disassembled the digital dash but I cannot find the R1~R9 chip that is pictured.
The digital dash has two large chips connected to the speedo/tach combined display and the R1~R9 resistors don't match up to the info provided (eg. R1 is neither 62k or 130k resistance).
Also R1~R9 are scattered across both chips.
Any help would be greatly appreciated!
If I can just figure out which resistors are for the tach it would be all I need.
(Unless they were directly under the digital display in which case I would set fire to said car.)

AH thanks for the tip. I'll have a search.
The 7mgte blew up, which gave me a great excuse to drop in a high compression built na motor. Maybe I'll return to boostlyf a few years down the track, but it'd probably be in another car/or another mk3 supra shell.
offtopic: Your supra has been quite an inspiration for mine. Honoured to have you reply to my post mate
