    Re: Project dyno

    Widebands were available back in 2002....just very expensive. I still have my old FJO controller from back then, I think it cost me near 800...and that was with a more favourable exchange rate than today ! lol

    Although narrowbands could be used to give some info, but used with caution, I was using them to assist with tuning from the mid 90's.

    As for the dyno controls...I guess there should be more modern control options for them ? Either from Superflow or others ? I've seen guys build their own dyno's, and then sourced control software from other companies.
    So I'd guess it would be possible for this too...some time in the future if funds or the need arises..

    But as you say, it will work, it will give numbers...always gotta start somewhere.

    I thought I'd leave you to correct that.

    just in the same way that we used to tune engines by ear and looking at spark plugs, then came CO meters, and computerized rolling roads. although even there my first injected 2002 was mapped by dave walker, no such thing as O2 sensors at the rolling road, and the CO meter kept crapping out, we had never heard of meassuring EGT either, so it was mapped like you do timing he just added fuel until the power stopped going up! nowdays there practically nothing you cant log.

    the 901 is basically obsolete as various bits are unobtainable or no one knows how to fix them. its a bit like taking a 1990s computer running windows 95 down to PC world and asking them to fix it, your just got told "sorry mate its too old buy a new one."
    Well my hats off to you sir! I must admit I always admire you guys who can work these machines, it's like the old school tuners on rolling roads with carbs, it just an art, and a dying one at that.
    I'm actually going in reverse/old school myself and going back to carbs with a BDG, I tried TB and ECU and just think retro needs to be just that and keeping people in work to keep it going is a must IMO.
