Last night after changing settings to 36-2+2 I got the Rally Neon started and running!
![Rock ON :rockon:](./images/smilies/headbang2.gif)
My setup is a BONE STOCK 2003 SXT SOHC MT - wired for standalone. Besides being a rally car - Build Log - viewtopic.php?t=57224
The plan is to get the wiring and settings dialed in with a "known good engine" before dropping in the "hot motor" with compression and cams.
We're going all motor instead of turbo so that we can continue to kick ass in the Group-2 class.

I'm using the stock harness so I can go back to the NGC PCM if need be.
I'm using all of the stock sensors! I'm surprised when I see threads from 2013 that ask about installing GM sensors.
I've got the coil pack setup for wasted spark as COP seemed like more of a hassle than a benefit.
Fuel is being run from the MS3X - goal is to get it full sequential, but I need a CAM signal before that will work.
Here is the 2GN NGC wiring guide that I made / have been working off of:

Here's the folder with my current settings and logs if you're interested: http://rallynotes.com/megasquirt/
Cam Signal Issues:
Checked with my scope and I have a good 5v CAM signal.
Never see cam signal on "Composite Log".
Where - besides ignition settings - do I have to specify the cam input as "MS3X Cam In"?
Will it only show up when I set the fuel to "full sequential"?
Here is my latest .msq - http://rallynotes.com/megasquirt/2013-1 ... .36.35.msq
IAC Issues:
As mentioned - using the stock 2 wire IAC. Certainly easy to power with 12V and connect to the PWM Idle, over the 4 wire 1GN model.
It only starts to open at like 80% and then is full open at 100% - what settings should I tweak here?
I noticed a pretty god awful squealing noise when set to default 1021Hz. I set it down to 500 and that went away, but I think with PWM it means it may run hotter. Any recommendations here?
By The Way:
This is a SymTech Labs MS3 - and although I was disappointed with their production and delivery expectations. I'm impressed with their build quality and setup. The computer came with a base map for my Neon and after selecting the correct settings - started up surprisingly well.
