help with tachometer - 240sx ka24de

[ric77]

Good day, I am writing from Panama
my English is not very good

Buy a 240sx 90 with KA24e and I made him swap a KA24DE, KA24DE was installed with his harness, but the ECU I use is the single cam(ka24e) and tachometer, the tachometer is coming mph digital.


all works fuel, temp, digital km, less rpm (tachometer) does not work
.

how to fix this the operation of the tachometer?
the ecu problem?
problem by not connecting to the rear plug?
power failure?
what color cable indicates to me the ecu rpm?

thanks

I don't think you will get tac working without dohc ecu and gauge. If it is a problem with wiring it is the yellow and red stripe wire going from ecu to dash harness. You will have to wire up the plug from the sohc to your dohc harness.

help with my problem, i need used tach.

one questions, whats ECU is best, the ka24e or ka24e?, i have both, but my ka24e ecu i have a chip with ebay chip to eliminate the speed limit, the KA24DE has a speed limit?

oh i have the chip with my ka24de also?
I ask this question, because maybe changing the ecu to the tach doch serve me and only I put the chip?

They use different tachs, you can swap the tach motors.
