mallory unilite
hey guys, have a 79 280zx n/a running msv2 3.57. not getting any rpm signal to the ms with a mallory unilite dizzy. have replaced the optical unit with a new e-spark. have a resistor in the signal line to 12v+. signal line is pin 24 using pin 36 to trigger a coil. confirmed 12v+ while craniking, have connected everything to the battery for diagnostic purposes temporarily. i am using tunerstudio as my software. ms was on a different 280zx with the same dizzy and it was running previously. any help is appreciated. have tried many different settings for ingnition but just can seem to get anything.

Re: mallory unilite
Could you post a copy of your MSQ? That would let us check your settings.
Re: mallory unilite
you know id love to, but havent figured out how to yet. i can do regular photos, but not files. if you have some instruction i can. actually matt i emailed you mine yesterday so you can post it if you would like.

hey does not having the purple fuel pump wire affect anything guys. i never used it as my pump is wired to the key. i had a dream last night. lol i was going to get around to it eventually, but i figured if it works then why worry about it. anybody else have any ideas????
Re: mallory unilite
When you say 'wired to the key' is this something you did? Most injection pumps are wired so they don't run continuously with 'the key'.shady280 wrote:hey does not having the purple fuel pump wire affect anything guys. i never used it as my pump is wired to the key. i had a dream last night. lol i was going to get around to it eventually, but i figured if it works then why worry about it. anybody else have any ideas????

Re: mallory unilite
my car has always been like that. there appears to be no mutialtion of the factory harness for the pump either. once i have this signal thing figured out, im gonna re-wire the pump to be triggered by ms, it really is safer, i do agree. right now the priority is to hear it run and this is stumping several people all over the country. does anyone have any ideas, not getting the traffic i was hoping for here. i wish i had an osiliscope.
Re: mallory unilite
to add some extra info, the stim board does work 100% it varies the rpm in tunerstudio, so its gotta be this dizzy or the wire itself, or the settings. would i be able to see the rpm signal even with the incorrect settings???? the trigger logger seems to come up empty handed.
Re: mallory unilite
Just to recap. You have a Unilite dizzy - but with a non standard trigger in it. I'm afraid I dunno what an e-spark is. Is it designed to drive a coil as the Unilite is? Or does it give a low voltage output designed to trigger an external amp?
However, at very low RPM, like cranking, you should see the signal switch from high to low with a DVM - one with an additional bargraph display would be best. Or even an LED and suitable series resistor.
If it is designed to drive a coil as the Unilite is, try rigging it up with one and see if you get a normal spark.
MS can be configured to get its tach signal from a coil LT, direct from a sensor, or anywhere between. But I'd first make sure there is an output from your sensor/amp.

Re: mallory unilite
yes e-spark is identical to the normal unilite module. in fact it is an upgrade as the standard module "broke down" too often. im going to get out there this weekend gain and start at the dizzy, i dont think its the wiring, thats just point a to point be. its just hard when your brain is fried and your stuck. ill report back once i get info
