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.

    • I havent bought a manual cover for the dash yet and no cluster change, won't bother me too much, I just need to get that auto box gone, manual in! I miss my manual. 🤪. We started last weekend and managed to get the box out. Planning to start putting it in this weekend and then order a single piece tail. We were super careful to take time and not damage anything. It's my first time working under the car.  With my S15 mainly worked in the bay. This time, it was a headache because of three or four bolts only. They simply didnt want to leave thei homr and the one securing the tailshaft, another above the GB, and the one securing the lipstick was a shit. Mates mate, Davo caught fire 🤣, nearly opened his chest up with a grinder 🤦🏽‍♂️ and both mates nearly had a plate from the box land and slit their head open. Fun times. We all survived. Not the easiest working with limited access on jackstands. As I'm sure we can agree these are the memories which make us love our car. For all three of us, was an awesome weekend and Sunday 3.30am before tools down was a fantastic effort. I need to upload pics, but looks like it needs to be via Url now. We used to be able to just upload pics back in the day. It's been that long! 🤪 Im currently spraying rustoleum under body, not because it's rusted. It's super clean, but just so it's protected for the next 10 years. There was a few surface rust spots. Which pretty much wiped off with a 3M scourer.  Really impressed with how well the previous owner maintained it. Bank account went down so quick! Service, then GB - managed to get a spanking new 34 genuine box from Nissan. All the rest of the conversion parts from Kudos.  Went with a Nismo short shifter. New pedals and Exedy Clutch and FW. Ordered the Prp Rear Main Retainer kit which should arrive Friday and my first engine mod part just like I did with my S15 will be the Tomei Expreme Turbo Outlet. Already on order. It'll likely sleep next to me on a pillow during the coming months. 🥰 Last build was on my JET200GT profile and on SAU and Hardtuned I had documented the build. Planning to try to do that again. Brands feel scarce now. Wish we still had ARC and Apexi parts readily available. Exhaust - need some advice on this. I had an Apexi exhaust on the S15 and loved the tone. My mate had a HKS HP Silent on his 33 and suggested I go with that to avoid drone. I can't remember hearing an RB25DET running that so will likely need to wait for a meet or something to hear it.  Not after big power, just enjoy building it, and drivability with minimal negative attention.
    • Have a chat with Ben at Moore Performance or Jesse at JS Performance.
    • Thanks both. All good advice. Reminds me of drilling through stone wall for drainage pipe 😬 I'll let you know how I get on if I still have use of my hands afterwards 😅
    • Finally got shipping number for the intake and throttle body, shipped by UPS, so "should" be in my hands sometime next week, fingers fracking crossed
    • I'm so far behind in the jobs I have to do at both work and home (including car) that I have become immortal. There's simply no way that I can die now.
