skirkland1980 Posted June 12, 2013 Share Posted June 12, 2013 I'm trying to eliminate my spark blowout with an MSD 6A box. Can megasquirt send a proper signal to fire the MSD box? It appears that the new MSD boxes are now digital. I found these instructions http://www.megamanual.com/ms2/msd6a.htm So I just connect the white wire from the MSD box to pin 36 of the DB37? Is that it? Will I still have control over ignition timimg? Thanks Quote Link to comment Share on other sites More sharing options...
Matt Cramer Posted June 13, 2013 Share Posted June 13, 2013 How is your MegaSquirt currently set up for spark output? It should be OK to control timing through the MSD box, but in some cases may need hardware mods. Quote Link to comment Share on other sites More sharing options...
skirkland1980 Posted June 14, 2013 Author Share Posted June 14, 2013 I'm using D14 to a 330 ohm resistor to the bip373 to a single coil. I guess I will have to change dwell in the ini file. Is that tricky? Also I already ordered the custom trigger disk for the L28ET that you sell. Can I still use it with a single coil? Will it make any difference? I will not be using wasted spark at this time. Thanks Quote Link to comment Share on other sites More sharing options...
Matt Cramer Posted June 14, 2013 Share Posted June 14, 2013 That should be fine. With Extra code, which you seem to be running, you do not need to change the INI file. Just set the dwell to fixed duty, 50%. Our trigger disc will work fine with a single coil and give more accuracy than the MS2 supports with the stock distributor.

skirkland1980 Posted June 17, 2013 Author Share Posted June 17, 2013 Alright, Thanks. I just finished the install yesterday and wow was it easy! The car fired right up. As soon I my transmission swap is done I will update with further results. Quote Link to comment Share on other sites More sharing options...
