Just installed my mallory VI CD unit and car runs fine with the box out of the loop, when we hook it up it backfires through the exhaust. Anyone else have a problem with this when hooking up an aftermarket ignition box? Talked to mallory tech and we both the from the increased spark and the bundled passenger side wires to get it through the pulleys is causing the spark to jump between wires. Any comments are very welcome...Thanks

 

My passenger side wires are bundled too and I dont have that problem with my Hyfire.

 

The coil was apparently bad and spark was coming out of it. Replacing tonight. The #8 plug wire was arcin but I think it might be because of the coil. Will find out soon and post back.

 

Update: Dad went and bought some POS coil and the car ran like poop even without the box on, switched back to the stock coil and insulated it with some electrical tape and it stopped arching. Car still ran bad with box on. Flipped the master arm switch which had the high speed retard attached to it and the car purred like a kitten. Apparently 12 volts have to be applied to the high speed retard at all times. Feeling purdy good right now

 

where did you mount your box? do you have any pics? i cannot get mine (model 685) to fit next to the K&N.

for the high speed retard, if you have 12 volts running to it, isn't it retarding your timing to the set degree?? the violet wire for the window switch, is it supposed to be a ground? i am a little confused on all this.

 

We spliced the wires, extended them, and ran the box to the glove compartment. Your thinking is logical on the HSR that when 12 volts are applied to it then it should be affecting the timing, Right now I just run with the master switch on since the solenoids are not installed. The retard is set on .1 so it wouldn't be that noticeable. Have to rewire it soon, though. The violet wire is not supposed to be a ground to my knowledge, might have to look at my diagram again though.

 

that is exactly where i am planning on putting mine, in the glove box. i could not think of anywhere else to put it. i got some extra wire today so i can do it.

 

I put mine in the glovebox also...easy to get to .

The violet wire is for the window function which supplies a ground path for your nitrous activation when your in the rpm window you set...very simple to wire into the microswitch.

As for the high speed retard.....mine is active all the time because I went strait to a 12v source.....Ive been meaning to rewire it to the nitrous master and see how it works out but havnt tried it yet. I belive it should work ...just wonder if it will remember its setting when the nitrous is turned off and then back on. Maybe Ill try it this weekend.

Make sure you have a real good chassis ground and that all wire is the same gauge as the harness it is used with.

 

You may need a better than stock coil.....Im running a Crane Blaster coil .

 

yeah, the wire i am using is the same gauge, and i have an accel coil. i don't see why the retard would forget where it is set, since it is programmed into the box itself, which has a constant power

 

gb95zconv, what do you put your HSR on whenever you're not running the juice? .1? Thanks.

 

Mine is at 2* all the time because you never know when you need to go

S.C. is right though....it should work fine off your nitious system master switch....we'll see this weekend.

 

I think you'll find that in theory and reasoning, this sounds right. But it doesn't work. This is how my box was wired and it ran like total sh*t (Backfired through exhaust, etc) but was still driveable. We flipped the master switch which had the HSR attached to it and it ran just as normal as anything. So unless you want to go around with the master switch armed all the time it won't work. Who knows, though, maybe you'll find a way we didn't think of. Either way, keep me updated man. Laters.

 

It well get hot in the glovebox. I don't know about Mallory, but MSD is quite clear that mounting in the glovebox is not to be done and voids the warrenty. These units have large heat sinks, and need air flow to cool. I have mine (MSD D6) mounted on the front of the left fenderwell just below the fuse box.

 

the mallory won't fit in the front well there below the fuse box. i just drove fro a few minutes and mine was hot in the glovebox. i don't think it should cause too much of a problem, though.
