Here is a good one....

I have heard from the grape vines that when you do a sr20 swap, there is a way on how to wire from the ecu so the rpm's work on the stock tach.

Has anyone else heard this and how would it be done?

Thanks everyone...

 

i'd imagine that you wire it the same way, all it is is a sensor.
I think.

Do a google search for "tach wiring"

 

mine works fine and its was done when i had the wireing harness done. its was a plug and play/drive setup

s13sr20 in 98 s14

 

I heard the Newer 240's work.

Its for a 1990 240, older tach with s13 engine

 

ah, my bad man...

it shoudl work still though because its an s13 to an s13. did you do the wiring yourself?

i do have a ecu pin out diagram if that would help

email me if you need it. ill send it to you right now

 

I thought s13 were from 1991 and up. I think the ca18 engines were in the 89-90 models, or I'm I wrong on that??

 

im not sure...but he motor and the car are still s13. you probably need to hook up the signal wire to it and see if it works

 

Thanks, I'll check into that...

 

89-93 were s13's (s13 is the chassis code, not engine)

89-90 had the SOHC KA24E
91-94 had the DOHC KA24DE

 

I'm thinking more in terms of engine and the japanese versions. I should not say s13.

sr20det for 91 and up and ca18turbos for 91 and down.

Is this right??
