skirkland1980 Posted January 3, 2013 Share Posted January 3, 2013 Running ms 2 v 3.57 on 1983 280zx L28E. It has the stock vr distributor with a single coil. Has low impedance 440cc injectors (2.0 ohms each). All ms grounds to the battery negative, sensors ground to the intake manifold. I have a toggle switch to the battery to power ms. Everything is fused and relayed. I'm not having much problem anymore with the box getting hot and the engine misfiring that I've noticed. The main problem I'm concerned with now is ms isn't following the spark table. IGN is soldered to pin 7 of the 40 pin dip socket to a 330 ohm resistor to the bip373.

Matt Cramer Posted January 3, 2013 Share Posted January 3, 2013 This could be a case of firmware corruption; try reloading the firmware with the latest version, and making a new tune from scratch. Quote Link to comment Share on other sites More sharing options...

skirkland1980 Posted January 4, 2013 Author Share Posted January 4, 2013 I have good news and bad news. I drove the car to work this morning from Stockbridge to Macon(65 miles). The car ran good, no more overheated bip373. The bad news is, I reflashed to 3.2.4 and retuned and the ignition map still has no effect.

motomanmike Posted January 5, 2013 Share Posted January 5, 2013 Does base timing match MS with the trigger wizard using a timing light? Quote Link to comment Share on other sites More sharing options...
skirkland1980 Posted January 5, 2013 Author Share Posted January 5, 2013 I set it fixed timing, and try to adjust with the trigger wizard. The timing will adjust but not to what I'm trying to set it to. It jumps to either 0* or 30*. Then I set it to use table and the timing won't move when I rev the engine.

motomanmike Posted January 5, 2013 Share Posted January 5, 2013 The timing light jumps around from 0 to 30 during this or does it stay pretty consistent? Quote Link to comment Share on other sites More sharing options...
skirkland1980 Posted January 6, 2013 Author Share Posted January 6, 2013 The timing stays steady after I try to change it with trigger wizard. When I adjust with the wizard I get 0* or 30*. Quote Link to comment Share on other sites More sharing options...
motomanmike Posted January 7, 2013 Share Posted January 7, 2013 The timing stays steady after I try to change it with trigger wizard. When I adjust with the wizard I get 0* or 30*. Confusing post to me. For clarification to the guys, when you set trigger wizard to 30, does your timing light stay at 30? And when you set trigger wizard to 0 your timing light stays at 0.

skirkland1980 Posted January 7, 2013 Author Share Posted January 7, 2013 Yes. Timing is very steady. I welded all of the advance mechanisms in the distributor. Quote Link to comment Share on other sites More sharing options...

motomanmike Posted January 9, 2013 Share Posted January 9, 2013 Is it possibly your rotor button has slipped or does the NA car use a pop style rotor button like an older Z? Just brainstorming. . Quote Link to comment Share on other sites More sharing options...
skirkland1980 Posted January 9, 2013 Author Share Posted January 9, 2013 I don't think it's possible to have slipped. It slides on...IIRC... the turbo dizzy has a screw in the rotor. Quote Link to comment Share on other sites More sharing options...
motomanmike Posted January 9, 2013 Share Posted January 9, 2013 (edited) Do you have any data logs you can post since the reflash? Edited January 9, 2013 by motomanmike Quote Link to comment Share on other sites More sharing options...
skirkland1980 Posted January 10, 2013 Author Share Posted January 10, 2013 No. I can get one. It runs pretty bad now. Matt said I should make a new tune from scratch and see if I have the problem with the stim. Quote Link to comment Share on other sites More sharing options...
skirkland1980 Posted January 15, 2013 Author Share Posted January 15, 2013 Matt figured out my problem. My trigger angle was in a bad area. I set it to 60* and fine tuned the timing by adjusting the distributor and it's working perfectly. Thanks Quote Link to comment Share on other sites More sharing options...
