My 3.2SS The final Chapter - It runs
 

First, a link to previous posts on the build. I rebuilt the top-end due to head stud failure.

MegaSquirt ECU (MSII-V2.2)


A few weeks ago I was able to get the motor back in the car. Last week I finished wiring up the motor only to find that my Crane optical trigger was not working. Late Thursday night I sorted it out. (Read: A new one was delivered by FedEx Ground).

So I connect the ECU, disable the motor, pull the top plugs and spin the motor with the starter. I was getting about 1.2-1.3bar of pressure off the starter. Enabled the engine by connecting the ECU and installing the plugs.

I was not expecting the motor to start right away. The motor took half-a-turn and fired to life. I was a little freaked out and shut it down quickly. I am not sure why. 10 seconds later I fired it up again. Once it was running I stabilized the map and it was loping along at 2100 rpm to break in the cam. It was running a too rich to explain the loping. After my 25 min cam break-in I made some more changes to the EFI map.

Here is the result:

now I need to reset the AFR at idle, balance the throttle shafts and lean out the acceleration enrichment.

I am so stoked right now. I don't know if the high is from the unburned fuel vapors or natural euphoria.

Not a drop of oil anywhere that I can find.

Excellent: There is no better feeling, at our age!

Your brave setting up a video for the first crank!

Truth be told that was after I did the cam run-in.

CONGRATS, Jamie!

So, this will be out on the New Years Run and the Hill Country Rally.

Look forward to seeing it in person, excellent work.

See you soon.SmileWavy

Thanks guys. Yes, the plan is to have it on the road for the New Year's drive. I need lights, door panels and seats.

Bob, Are you headed down for the drive? We could find a location to meet off 281 if you want to come the back way.

Jamie

I just saw the e-mail so I have not yet had time to check schedules, but I will try to fit it in. Will let you know.

Woohoo!

Days like this are what it is all about!! I feel sorry for those who do not play the game.

Jamie,
Congratulations! i can't wait to share the road with you on the 3rd. I sure hope the weather holds...:rolleyes:

That is a really impressive project. I know you have untold sweat equity in that machine. You can be justly proud when your lap times pay the dividend for your work.
