jacob80 Posted March 24, 2009 Share Posted March 24, 2009 Hey guys, so take a look at the diagram below and this one Is there a reason the top diagram incorporates a "GM HEI" triggering module while the second does not? Is the HEI 4-pin unit necessary for the install with the '83 280zx turbo distrubutor?? Additonally, we are using Megasquirt 1 with PCD 3.0 board and will be controlling fuel and spark with MSnS-E Quote Link to comment Share on other sites More sharing options...
jacob80 Posted March 24, 2009 Author Share Posted March 24, 2009 Ok just did a little reading and can I just go completely by this guide: http://www.diyautotune.com/tech_articles/how_to_megasquirt_your_280zx_turbo.htm Quote Link to comment Share on other sites More sharing options...
mobythevan Posted March 24, 2009 Share Posted March 24, 2009 The first picture you show is from my install guide which is made for v2.2 pcb so you can disregard it if you are using v3 pcb. Here is a link where I talked through the same issues that concern you: http://forums.hybridz.org/showthread.php?t=145679 So, depending on the stuffing options of your v3 pcb you can decide what works best. The link you posted for the install writeup at diyautotune should work great for you. Quote Link to comment Share on other sites More sharing options...
jacob80 Posted March 25, 2009 Author Share Posted March 25, 2009 I have a brand new blaster 2 coil, will this work fine with the DIYAutoTune write up? Also, what kind of connection is made where the wires "t" off for the pull up resistors? And from my understanding, if you're using the IGBT on your board, you dont have to use the GM HEI correct?

Matt Cramer Posted March 25, 2009 Share Posted March 25, 2009 The IGBT (or Bosch transistor, which technically isn't an IGBT) eliminates the need for a HEI module. There are several types of Blaster 2s; if you have one that can be used with a stock type ignition it should work. The ones that are supposed to only work with a CDI box are probably not ideal. To answer the "what kind of connection?" It doesn't much matter if it's crimped or soldered, just don't use wire nuts. Quote Link to comment Share on other sites More sharing options...
jacob80 Posted March 25, 2009 Author Share Posted March 25, 2009 Well how do I know which Blaster 2 coil I have? I believe we bought it at Advance Auto as a generic part. We also have an Accel coil which we were using in our 240z with stock electronics. Quote Link to comment Share on other sites More sharing options...
mobythevan Posted March 25, 2009 Share Posted March 25, 2009 Does it have a part number on it? Quote Link to comment Share on other sites More sharing options...
jacob80 Posted April 4, 2009 Author Share Posted April 4, 2009 Yes, it is the MSD Blaster 2 PN 8202, I have retrieved the manual and the link is below: http://www.msdpower.com/download/8202.pdf In the beginning section of the manual, a note reads as follows: "This Blaster Coil Kit is intended to be used with an MSD Ignition. If installing on a stock, points style ignition system, a 0.8 ohm ballast resistor or resistor wiring MUST be installed. MSD offers this Ballast Resistor as PN 8214 or the Blaster Coil Kits, PN 8200 and 8203 are equipped with one." How will we set up the "resistor wiring" with this coil? Should we just follow this diagram if we're using the relay board?: Quote Link to comment Share on other sites More sharing options...
