    Default [TAS] ULTRA DIRECT IGNITION SYSTEM (CDI for UDI)

    NOW LOCATED IN MELBOURNE EASTERN SUBURBS

    Bought this and never got to try it, went straight to aftermarket
    The CDI unit looks a bit rough, but was pulled as a working ignition from a ae86 jap import car with a Blacktop 20v before i got it.
    It is a batchfiring/waste-spark setup, firing in cylinder pairs. its got:

    Ultra CDI Ignition section loom and plugs, one plug to main engine harness, 4 wires, igt,igf,+12,- (im pretty sure, there's definitely only 4 wires to the plug so I assume these are something like that)
    FSD unit (fire sequence determination..)
    ULTRA CDi unit - looks like CRAP, main reason i went straight to aftermarket. will probably need to be tested before installing, someone opened it before i did and cut away insulating silicone, case is cracked but the card is intact and all fine, no black burnt bits, its definitely been tested in some way previously, so its either busted or working. I have no idea never tried it, can't test it.
    Individual ULTRA coils and great leads
    20v Blacktop 4age stock ECU M/T
    Hall effect sensor and bracket attaching to exhaust cam pulley.. theres some info here: 3rd photo down is the same looking setup as this one.
    Good cheap solution for dizzy-less ignition DLi for rwd ae101, ae111 etc or even for 16v for crazy spark

    Cheers

    $250

    - you can buy yourself another new aftermarket cdi (MSD?) for 200 bucks
    if worried about the Ultra's condition. Sorry guys I have no idea if the cdi works or not I don't know how to test it cause its 450volts apparently, don't want to play around in there.
    Its been priced accordingly, still a cheap legal alternative to aftermarket.
