#1, "Megasquirt stuff... Looks like I'm almost ready."
About a month ago when I was trying to get my car back on the road, I broke my old IAT sensor - the therads broke off in the manifold and the rest of the sensor was junk. Good thing I had a spare upper intake manifold around, because I couldn't get those threads out for the life of me.
So, I brought the disgruntled manifold and the GM IAT sensor to my local machine shop and they drilled and tapped my "old" manifold to fit the larger GM sensor. I like how it turned out. Looks totally stock!
There's the board. It's been broken for the past few weeks, so I found the time to debug it and discovered that I was powering the board along with 4 injectors off of the stimulator board, which has 2 tiny PCB traces for +12 and ground. If I designed it, I would have made it more like the flyback board with a power plane and a ground plane on oppisite sides of the PCB. Oh well. I fried one of the cheesy power traces while trying to pull enough current to drive 4 crappy old fuel injectors. Fixed. I'm now running the 022e4 code, I will start off with fuel only, then I will hook up the ignition system. I have no idea how stable this code is, it's a new release. Hell, I have no idea if this entire setup will work at all. I've never done this before. However, everything seems to work as it should on the stimulator, but we'll see how it works in the real world. Hopefully I'll get it done over the long weekend. Anyone have a VE map I can start off with? I have stock cams and will be using 780 cc/min injectors.

nice, I have an xtra plentium that I will be doing the same too. I already paid MrSlick for my MS. I have collected up all the sensors/ignition parts and the new injectors. More or less just waiting on the MS unit. Good job on that. These are the fuel injectors I got. Although when I tested the ohm load I came up with the same as my stockers.

Is that a Plentium 4?
I'm in your boat too. My harness and sensors should be in this week and I'm just waiting on Lee to get my MSnS here. (This week, right Lee?)

Although when I tested the ohm load I came up with the same as my stockers. Part Number 3105 Static Flow Rate (GAS): 86 lb/hr @ 43.5PSI (300kPa) = 903cc/min, 10.88g/s Static Flow Rate (Test Solvent): 83 lb/hr @ 43.5PSI (300kPa) Coil Resistance: 2.35 Ohms / Low Impedance / Low-Z (ECM driver modifications required)
I'm in a similar boat, I have paid Mr. Slick (28th of january) and am awaiting my unit. I have not purchased any sensors or anything, and will be running on my (mostly) stock car for testing before I install a turbo (which I am ordering today). Do you know of any lst of other hardware we need to run fuel + ignition, or a link to another post that mentions them? Mr. Slick said he was backordered a bit when I ordered, hopefully he's caught up soon .

Good stuff...I sold my 8 injector setup, and just paid Lee for the MS'n spark setup! This is going to be fun..The plan is to max out the S16g on pump gas
One more thing, where are you guys getting your injectors from?? I found "racetronix.com" where they had the Delphi 780's for like 57 bucks each... http://www.racetronix.com/17113742FM.html

From what I know, Lee runs NO flyback board with the low impedance injectors, and his has been doing just fine. BUT it would prob be best to use the flyback board, just for peace of mind I suppose..
So is that link I posted, where you guys got your injectors? Or where did you get them?

The flyback board is only necessary if you're using very low impedence injectors. The ones that Lee is using are around 4 Ohms. Anything less than that you'd probably want to use the flyback board.
