    Hi guy's, can somebody tell me what i'm doing wrong? I have had 2 goes at making the tacho booster with no luck. When i measure the tacho input wire it start with a voltage of around .6v at idle and goes upto to over 3v with a good rev. but when i measure the output of the tacho booster it starts at roughly 12v and goes down in voltage with revs. Help!!!

    I made the external style one, but made 2. 1 with all parts listed by whitzl. The second with all parts in this diagram http://img366.imageshack.us/f/coilnegemulator4ly.gif/.
    I cant decide weather i just order one from sideshow or try making the individual coil & diode set up etc. Yeah those pics would really help right now!

    My mate has a 4AGZE in his AE86 sprinter using stock ECU and DLI. He's asked me to help him get his stock AE86 tacho working and I believe he'll need one of these boosters since his tacho is after a large pulse that the stock ignition setup would provide.

    If I make or buy one of these, do I wire it up between the ECU's tacho output and the dash tacho, or do I need to get the signal from one or both of the DLI coils?

    i brought a ready made MSD one for just under $60USD+post and im less then impressed by it. its loud as fuck and annoys the shit out of me. might have to relocate it to the engine bay or to the boot then it can join its humming american walbro friend and they can sing together.

    that's some pretty huge markup from MSD.
    Costs under $10 to make one yourself.

    Does this solve the problem with AE86 tach and standalone ECU's ?
    I have VEMS, it outputs +5 or +12V, not sure but certainly not enough for stock tacho.

    Thanks
