msd input/output setup

Postby puredreamz83 » Thu Apr 26, 2007 4:48 pm

this might be a dumb question but my msd box is hooked up to the aux output.

what setting should this be on, ignition bypass ...

Why on earth do you have it hooked up to the Aux. Out?

What application is this on?

because thats the way the tech support at msd told me to hook it because the msd box has 3 main wires. heavy red positive. heavy black ground, and a thin red wire to 12v source such as ignition key or switch.

They gave me a wiring layout that they said to hook up to the haltech aux output ( i handed them a wiring diagram of the E6X wiring diagram, maybe just cause it was beside the ignition outputs.

Everytime i talk to someone who said they've talked to MSD techs i get a headache, those guys dont know their ass from their coffee mug, if you would've asked us first we would've told you that the if your only using 1 coil, connect the Haltech's Ign1 output (light green wire) to the MSD's white wire like its always been done since the dawn of time.

And the thin red wire on the MSD, goes to 12V switched power, meaning a wire that has power when the Ignition Switch is on the On position as well as onthe Start position.

ok i m running 4 coils i ve got that all wired up but right now as it stands the thin red is connected to that aux out.

Is that causing a problem...

i m not getting an rpm signal could that be a problem or is that something else.

What MSD unit is this? DIS 2, DIS 4?

Of course thats your problem, that wire goes to 12v switched power!

The MSD isnt working because its not powering up. Wire the thin red wire on the MSD to a 12v switched source that has power while cranking, use the same spot you connected the Haltech's gray wire.

dis 4

Postby puredreamz83 » Sat Apr 28, 2007 6:15 pm

Its a dis 4 digital plus.

Isnt that aux output under the ignition outputs a 12v switched.

Dont u even have the option of running 0-5v or 0-12v under the input/output setup.

Which gray wire are u talking about.

Listen, the Aux. Out isnt meant to be used as an activator that way, this is why i suggest you use the same location you used for the gray wire, and if you dont know what the gray wire is im starting to doubt your qualifications to install your haltech and you should take it to a professional.

The gray wire, as indicated on the documentation you should read if you havent, activates the Haltech when power is applied to it, much like a car Amp would require the radio to feed a 12v signal to turn it on. If you dont connect this gray wire to 12v switched when you turn the key the haltech (and consequently the MSD) wont power up.

Now do you understand?

Also, what ECU are you fooling around with?

so this could be a syptom of a no rpm reading

Of course its never going to fire if there's no rpm reading, the haltech doesnt know the engine is spining. Fix that, and connect the msd the way i indicated.

yes sir i ll let u know what happens.

One more question before i do that could it be that the crank wires arent shielded cause alot of users mention the sensitivity of the e6x unit with ignition noise. BUt would this really cause no rpm reading !

ignition noise is caused from the electricity passing through the ignition system (plug wires, etc.). if you don't have spark, you can't get ignition noise. so no, ignition noise cannot be the cause of your 0 RPM reading.

well i ve got rpm, spark and fuel. But car still wont start.

i think it might be the base that someone gave me and the cold start settings.

Computers telling me the intake temp is -40 and the coolant temp is 32 is that a normal reading ???

application corrado with 1.8t motor using the 1.8t green coolant temp sensor for those who are familiar.

Where in the world are you? what are your current ambient/temperature/altitude conditions? if the air temp reading is -40 your sensor is not connected right, or one of the pins on has come loose, either way -40 means opened circuit on the temp sensors, unless you really are at -40 degrees of air temp, like in the arctic maybe?
