    Tuning factory ECU

    Sorry if this is in the wrong section but I was wondering if the factory ECU can be programmed/remapped without any interceptors or stuff. I know the Nissan ECU's are generally tamper proof but I'm pretty sure there was a bloke in Aus who had cracked the CA18 ECU. Just wondering if there was anyone who has cracked the SR20 one.

    Cheers

    Yes and no. Yes it can be remapped, but it requires a replacement chip. I don't know what's available over in Oz, but there's a guy in the SXOC who specialises in S14/S14a/S15 chips - either pre-mapped or he can do a custom mapping.

    The biggest problem in the UK was the NATS2 alarm on the Euro S14a. The alarm and immobiliser are incorporated into the ECU and makes it NEARLY impossible to remap without immobilising theh engine. Jez worked it out though

    Yes. There's a specialist in melbourne, australia who can tune the stock ecu. NIZPRO is the company's name.

    You're missing the point. Programming the ECU direct is much more precise. A chip upgrade is also half the price.

    You can't map it yourself though.

    If I chip it for $980NZ then wouldn't I be better off saving another couple of hundred and get an Apexi PFC?

    If you want a custom mapping, it usually costs me about ?70. That's 2-3 hours on-road mapping, not on a dyno.

    well, PFC+Controller was like 1500+ 2 years ago and with tuning almost 2000NZD\


    now, PFC+Controller = 1100~1300AUD and you get it tuned probably cost you 500+ for a good tuner like Croydon

    but the stock computer has EVERYTHING going into it. it takes into account everything and i think it's got a finer resolution.
