hey guys, im sure many of you at some point in time modified the stock wiring so here is my conditionned question
when I bought my car, none of the dash lights worked, half the fuse box is missing, and the fuse box has fuses which dont do anything, now I am not that bad with circuitry and I tried my best with dash lights, could not get it to work, so than I just directly wired my cluster lights
i am wondering what I can get disconnect without allowing the ecu to go into a lockout mode (safe running), for example, my speed limiter/rev limiter controls involve interruption of multiple sensors on the transmission, when I shut down those circuitry does it make the ecu change timing into the lockout mode ? i also plan on mechanically advance my ignition timing, and if i disconnect the sensor to my distributor, would that once again go into the lockout mode and change the fuel map ? eccs is pretty complicated, i would like to be able to prevent the ecu from changing things on its own (i read this in the manual, it adjusts according to how you drive), i want it to always stay the same no matter what i do, i dont care if it wastes gas or whatever, i just need this done so my poweband stays constant, can someone help me out with this ? ka24e made in 89
i also found this http://www.ka24development.com/ecu_codes.html
but i dont knwo if its even correct when i do the diagnostics hence i NEVER seen my engine check light on, and never seen my low gasoline or any of the lights working
To check diagnostics on the S13, you need to unbolt the ECU from its holder. Once it’s free, you can turn it until you see this little recessed screw on its side.
With a small screw driver (jewellers) turn that screw all the way to the right (clockwise) until you hear it click.
Then it will start flashing the LEDs at you.
They’ll come in sequence
1.1-2.2-3.3-4.4-5.5 and then start back at one
When you see both LEDS flash 3 times, quickly turn the screw all the way back to the left.
Don’t worry if you miss it, it will always repeat 1-5.
This will lock you into diagnostic mode 3.
After a pause, it will start flashing at you in a sequence. Have a pen ready to write it down.
Each flash of the LED’s represents a number. The green LED is the TENS, the RED is the ONES
So if the green light flashes once, and the red 4 times, it has a value of 14
so you write down code 14. Then it will give you the next, then the next. Keep writing them down until the codes start repeating.
I don’t have the codes handy, but I can post them up later if you need them.
thanks alot man, so it’ll flash one of the LEDs on the cluster even though theres no check engine light like the other site i posted said, alright, thanks
The LEDs aren’t on the cluster, they’re on the ECU itself. There’s a little inspection window (small oval slot like 1 x 0.5 cm) on the side of the ECU.
You have to undo the two 10mm bolts that hold the ECU into the footwell. When you do that, the ECU can hang freely from the harness and you can turn it to see the window.
This image shows the switch, and the window is to the left of it in this picture. Yours may be in a different spot on the case, but they ALL have them somewhere on the outside edge of the case.
see ? no check engine light!!!, how do i do ecu diagnostics than ?
