The next step is gonna be getting this thing fired! And that is not far off now.
I am so close to lighting this beast off I can almost taste it! I had a horrible time getting the 24 tooth reluctor wheel getting its signal to the MegaSquirt. It took 6 days of messing with it to get it straightened out. But finally I got it working!!! By the way, these truck coils make a HOT spark! No I didn't get zapped, but watching those arcs across the plugs while I cranked the engine was quite impressive. My MegaSquirt II will definitely control both fuel and spark on this swap. I am pretty happy with that.
Here is the MSII and relay board mounted on the drivers floor, drivers seat has obviously been removed in this pic. The wiring on the left is temporary and will be removed and replaced with heavier gauge wire and neatened up considerably before she hits the road.
Under the hood things have come a long ways too. The fuel system is all plumbed in and looks awesome. I have powered up the fuel pump a whole bunch and it works awesome. The Bosch 044 is LOUD, but when the motor is running I doubt I will even be able to hear it. Exhaust manifolds are in place but will be coming back off to be sandblasted and painted with high temp paint before turbo mock up starts.
Here is a video I made for another forum I am documenting this build on. It explains a little bit about the MegaSquirt system and how it works.
Stay tuned. I am really close to hearing this thing bark!

It lives!!! She is alive! MS2 Controlling both fuel and spark on an LSx with nothing but the 24 tooth reluctor wheel for an ignition reference!
I won't be updating again until mid April. Uncle Sam has seen fit to send me to a tech school for a couple months and I am leaving shortly. But I did at least getting her running. It is obviously running pig rich in the video and it is so loud with open manifolds and in the garage that it just blows the mics away on both cameras. But it IS running at this point. I am pretty pleased.
Keep an eye out this spring for more of this thing!
Enjoy the vid and turn it up!

Go and read EVERYTHING at www.megamanual.com When you are done read it again, that will give you a really good understanding of what makes the MegaSquirt tick and should help you decide if the MS is for you or not.
Well I used this link as a rough guide to get going. http://www.msextra.com/doc/ms2extra/MS2-Extra_LS1.htm
That will get you in the ballpark of running a 24 tooth reluctor wheel LSx with an MS2. But the information there is a bit outdated and it took me a fair amount of tinkering to get this thing to light off. I had to change things around quite a bit to make it work, but as the video shows, it does work!

The base MS3 is $100 more than the MS2. The base MS3 still gives you batch fuel and waste spark, same as the MS2. To step up to individual injector control and individual coil control costs another $199. That brings the total for just the ECU to $577 as compared to $278 for the MS2. I couldn't see any reason to spent that much extra.
While there are a fair number of modifications that must be done to the MS2 to make it work on an LSx it literally is almost free over the cost of the basic MS2 kit. It is simply your time and a few pieces of scrap wire to make jumpers.
I won't say that the extra functionality of the MS3 isn't worth it, it is an AWESOME piece of hardware. But the MS2 is also an awesome piece of hardware and can be had for a lot less. Batch fuel and waste spark has been used, and continues to be used, to make incredible amounts of streetable horsepower.

Take a look at what it costs to run the MS3.

Finally an update!
This afternoon I did some work on the accessories.
I had swapped out the truck intake with an LS1 intake and was hopeful I could make the truck accessories work. This afternoon I decided to see if I could do it.
First I put the water pump on and the water neck for the radiator hose interfered with the throttle plate. A few whacks with the hammer and I rotated it enough to where it would work fine. But then I had to install the PS pump and alternator bracket.
When I tried to install it I found out immediately why folks say it won't work. Because it won't! Big time contact with the TPS sensor.
So I pulled it back off, yanked the idler puller and broke out the mighty sawzall.
A few minutes of surgery later I had something that just might work!
Dropped it back in place and voila, perfect fit.
I put the tensioner pulley on and with the help of blue painters tape figured out a new belt routing scheme. I am not sure if there is enough wrap on the crank pulley or PS pulley but at the very least it will get me going!
More to come but I am not too far off from a rip down the street. The next update should have some exhaust building goodness!
Stay tuned!!!!
