primordial how simple is it to do an ecu reset??

thanks

This is how I reset the ECU on my Subaru. I image the same will work. Its not the proper way to do it, but its by far the simplest. Its the simplest because I don't remember the other way.

How to reset the ECU, battery dance styles.

NOTE: Do this on a "cold" engine. Leave it sit overnight and do it in the morning.

1. Disconnect the negative battery terminal cable for 45-60 minutes.

2. Reconnect the negative battery terminal cable.

3. Turn off all your accessories.

4. Start the car, but DO NOT touch the throttle at all.

5. Let the car idle for 10-15 minutes, or until the car is at normal operating temperature. Again, do not touch the throttle.

6. Turn the ignition key to the "OFF" position. That's it.

take the battery off and leave off for 24hrs

but sounds like you have an electric short some where. might be best to take it to an auto electrician

Yeah as Mitch said - your best bet is to contact an auto electrician.

There's almost no way the ECU can decide to start the car itself... its an electrical circuit that is most likely shorting somewhere and starting the car... Just thinking though, how could the car possibly have run the starter motor for the specific amount of time needed to start the car? If it was properly shorted it would have grinded the starter motor into oblivion when the car started and the starter kept going..

Very odd problem! :P

Well it sounds like you're onto it now anyway. Get it removed. It's probably more of a security risk than a help.

whatever you do, do not cut the handbrake wire, unless you know how to remove that alarm, and get the car sorted. ( cutting the wire will disable the car and you won't be able to start it. had this on my old car took me ages to find)

if not take it to an auto electrician, or call a Mobile alarm guy and they should be able to take it out.

    • Learned a bit @PranK To add a twist to this take, I've done some further investigation and turns out I don't know if I even have coilovers. I have Mugen Showa on all corners, which appear to be struts / springs online. Someone may be able to correct me if I'm wrong. 
    • Well, i've been told it's going to be in Poland around october - november. It should set off by the end of this month. Waiting for it to arrive is the easy part, searching for the right car, wake up in the middle of the night to see the photos and decide whether to bid or not - that was difficult
    • Thanks mate, i'll keep that in mind. Not sure though if the black carpet will fit grey interior. I'd prefer original Stagea set but if i fail to find one in another few weeks, i will probably come back to you. p.s. - is this original, licensed Nismo product?
    • I'm a strong believer that old sports cars should be reserved as weekend cars and owned by mechanically inclined people. The risk-reward ratio is only acceptable under those conditions.
