  1. The Car idles and runs fairly smooth after it has warmed up. It is running a little rich according to the wideband (LC-1). 11-12 afr at idle. I've been doing a lot of reading and still have a lot to learn. I am somewhat familiar with fuel and ignition tables. This is the motor that was on pinks. It has been through a couple of people and cars before this one. I am trying to decide if I should buy a newer version of megasquirt. If this megasquirt is wired up correct and working, I will probably keep it for now. When installing MSnS on v2.2 to control ignition, the fast idle terminal is hooked to the GM HEI module, and the relay needs to be jumped? I will check and see if anything on the relay board is hooked to X12 or X11. I cant find anything that says X11 needs to be jumped to D17 for the L28et. Thanks Ben
  2. I recently bought a 280z with a 83 zx turbo swap. The car is running but not too well. It has a megasquirt 1 v2.2 ecu. I found the <a href="http://www.diyautotune.com/tech_articles/how_to_megasquirt_your_280zx_turbo.htm">How to MegaSquirt your 280zx Turbo</a> webpage. But the information is for version 3 not 2.2. From there I found <a href="http://forums.hybridz.org/topic/23244-megasquirtnspark-mssmsns-installation-guide/">MegaSquirt'nSpark MSS/MSnS installation guide</a> which is for version 2.2 . I've read through most of it and have a few questions. Looking at my board, XG1 & XG2 are jumped. Diode D8 has been removed and jumped. Which was covered in the installation guide. But X11 is jumped to one side of D17 (Injector LED), then a resistor jumps from there to R23. I've attached an image of my board below. Also X11 is jumped to X12 with solder. Im not sure if this was accidental or not. Also, the first relay on the relay board has been jumped. Is this the fast idle relay? The car has 460cc RX7 injectors and the orignal zx turbo distributor and trigger wheel. Any help is appreciated. Thanks Ben
