Thanks. I would really like to have this driveable before the end of summer. Assuming no major setbacks, I think its possible.

How do you get the belt out?

The bracket has a split in the base.

Here's a question for the hive. 

Had a bit of spare time yesterday so i figured I'd hook up the starter power and crank it to make sure I was getting oil pressure. 

Charged the battery and hooked up cables to my Focus for a little extra juice. A reasonable amount of cranking later, and I'm showing nothing on the gauge. Pulled the oil filter and she is bone dry. 

Cranking with plugs out and no electronics connected other than body fuse box. 

Any thoughts? I was going to pre-fill the oil filter tube and give it another go this evening.

Thanks

We have oil pressure! primed up the filter port, turned it over with some extra oomph and it filled up the filter.

On to wiring!

Thanks

Update. Wiring is complete and MS1 modified for EDIS.

Unfortunately, I am running into some issues trying to flash MSextra code to the MS1 2.2 w/ BG code. I've followed the guide on DIYautotune and it just won't update. I was able to confirm the USB adapter works and Tunerstudio does indeed show IAT, CLT. TPS, etc. data. So the ECU is functioning on the existing BG code. Below is an image of what happens when I try to flash the new firmware.

The boot jumper is installed when I try this. Also tried without, same result. I realize this is antiquated hardware and software, so finding a solution might be a challenge.

I understand Matt Cramer hangs around GRM quite often, so hopefully he will see this and offer some advice.

Thanks

He doesn't grep MegaSquirt so you may need to bug him directly, or start a new thread.  Paul_VR6 is also very knowledgeable in the MS systems.

 

That said, I have a 1.01 unit (may have got it from Paul actually) and one of its features is that the chip does not have a bootloader, so its firmware cannot be reflashed via cable.  Depending on how old your MS1 processor is, this may be the case for you, too.

I did an endrun by just buying a new processor, which had a bootloader.

In reply to Pete. (l33t FS) :

Thanks Pete! Perhaps I'll reach out directly but I hate to bug him. This chip does have the bootloader location, so I would have to assume it functions. Will continue to research a solution. Tried an older version of the firmware and it required a 16 bit operating system, which I do not currently have. I wonder if there would be a problem using a USB adapter to load firmware. Kinda unlkely in my mind since TS connects just fine.

Update: Fooled around with com ports and battery charge and was able to load up the correct firmware.

Additional update: 

The car has spark, but no fuel it seems. Starts briefly on a spray of ether. This is great because the ignition was the more in depth portion of the build.

Fuel pump works, rail is getting fuel. Going to check the injectors to see if they are functioning. Could be an ms setting I messed up, not super knowledgable about tuning. Something I'll be learning as I go.

Thanks

Been quite a while since the last update with the firmware debacle. After messing with different ports and charging the battery up, I was finally able to get Extra firmware uploaded. What followed was a poorly running car that took weeks to diagnose.

Turns out there was a mounting ear that was keeping my intake manifold from sitting flat on the adapter, causing a large vacuum leak. This was mended, several other adjustments were made, and she idles pretty well and revs freely now.

Still some work to do, various leaks to mend, but I am super stoked it runs.

Water pump replaced last night and it appears to be leak free. Existing unit was leaking out of the weep hole, I assume the seals degraded from sitting. 

Should be able to test the cooling system for further leaks later on this week.

Driveshaft components have been ordered so I can get moving on that.

There does appear to be an oil leak at the rear/ps of the oil pan. Not sure where that is coming from, something to address once a few other items are completed.

Cooling fan and shroud installed. Definitely moves a ton of air. Idle is tuned pretty well for not having an iac. Last item is a driveshaft and I can start some actual tuning.

Various parts of the build bother me, but I'll prob address them next year. Itd be nice to drive it here and there and enjoy it a bit.
