hey
i've got a 99 hyundai excel and it didnt come with a tacho so i've been trying to get this tacho i bought to work for months now i've taken the car/tacho to heaps of auto stores/electrician to try get them to install it, most places dont no where to get the tacho signal and the 1 place evan said my ecu must be broken cause its not giving a reading on the tacho wire (the white one according to them). i've heard im meant to hook it up to brown/white wire coming out of the ecu, however theres about 2 brown/white wires coming out of the ecu, i tried hooking it up to either of them and it still didnt work. anyone have any idea where to get the stupid tacho reading from ???
noone espeacily hyundai no howto install it for me.

thanks smile.gif

 

If your Accent (Excel) is the 1.5 SOHC then you cen get the tach signal right from the ignition coil. Its a 3 pin connector right at the ignition coil pack, take the middle one and connect it to your aftermarket tachometer and set the tach to 8 cyl. because of the waste spark system Hyundai uses.

 

Okay, for your 99 excel/accent.

You have a distributorless ignition that uses a dual(waste) spark system. (it fires 2 cylinders together).

If you hook the tachometer up to the ignition spark signal coming FROM the ECU, and set it for a 8 cylinder engine, it will accurately read the pulses.

Because of the dual spark arrangment, it fires twice as often as a standard 4 cylinder, and thus an 8 cylinder setup will cut the signal in half...which will read correctly.

I'm fairly certian that your ECU in Oz is different that our ECU in North America, however, www.hmaservice.com may be of use to you.

There are some tuning shops that specialize in Hyundai's in Oz, however the only ones I know of are in the Sydney area or the Adelaide area. I don't know of any in Melbourne.

Maybe Xtreem or some of the other Australian members can point you in the right direction to a closer shop, or you can try to call and ask one of the tuning shops near Sydney or Adelaide. Hopefully they can help you.

i just tried connecting the tacho to the middle wire of these 2 connectors near the ignition, both of the middle wires made the tacho idle at like 400rpm on both 4 and 8 cylinder settings on the tacho, (one of the middle wires was green i thought maybe that was it. wasnt though.....)i remember once i tried something a while back and it was idling at about 800 but then it wouldnt go up correctly like 6500rpm was showing as about 4000 on the tacho. i tried all the tacho cylinder settings nothing changed the reading.
anyways anyone got any other idea's thanks alot smile.gif
