    arnt flying looms for an adaptronic like $65- $70?

    if so, consider buying one, pulling apart your current loom, and basically copy it?

    that way, you arnt chasing your tail, you already know the loom your duplicating is set up / wired correctly as it runs your engine... but if you do it properly, chances are you'll remove any wiring problems (if thats actually your problem)

    something to think about anyway.

    thats not a bad idea at all.... my loom is simple as and i got all the diagrams.... and i can make it neater :O

    u got me keen now

    ive pmd ant to see what he wants me to do about gettin the ecu to him for waranty or getten sent to adaptronic and being fixed... i just cant wait for it to be riliable like it used to be before this happened the first time

    thanks for that man

    A couple of theories why the ecu would die like you have described.
    The ocv must be drawing alot of current therefore possibly a short/earthing problem or the ocv itself. Too much current supplied can cause components to fail.
    Another possible theory is alot of 'back emf' (reverse voltage spike when ocv stopped) back to the ecu which the diodes is probably meant to stop.
    Apparently stock 4AG Blacktop ecu's are prone to blowing the vvt transistor due to current surges when the vvt is activated.

    I'm looking to use adaptronic in the future and am curious to know what is creating the problem before you go to another brand....

    well there are heaps and heaps of people in qld using adaptronics on 20vs therefore using switched vvti...and i have never ever heard a bad thing about them... its just mine... so it cant be the ecu itself causing this problem

    earthing is a good explaination, that or a short....

    think im gonna rewire it though just to make sure
