Buzo's Accord & Megasquirt II EFI controller

New bracket, I don't think Lost would hire me in his shop, but this one is adjustable in the 3 axes.

Did you use any screws or anything else (besides press fitting) to keep the trigger ring in? I would be somewhat concerned about it working loose over time due to vibration.

---

I drilled the 3 holes precisely to add some screws to keep the ring in place. Pass thru holes in the pulley, built some thread, some thread locker in the screws and there's no place for the ring to go (I hope)

And thanks for your compliments! I'm still amazed how well everything fitted this time.

Ingenious indeed! And what I said on the MS forum about your pulley is incorrect. You DO have the standard Accord pulley. It was just hard to tell from the pictures you posted there.

I saved the best pictures for this forum :cheers:

Just finished building the PCB for the coil drivers... I guess I still have some time to give them a try today...

I see you discovered T-slot extrusions. Aren't they great? You can do all sorts of cool things with those.

Oh yeah, that's plenty good. It won't take much really to keep it in.

The fact that the Ford pulley fits right in the Accord pulley is pretty amazing. I should still have one around somewhere. I need to dig it out and do some experimenting.

Using those extruded aluminum pieces is like playing with legos :) you can build almost anything.

I found the information for the Hall sensor I'm using.
It comes in the Dodge RAM 3500 since 2005.
Just searched at Autozone and it's pretty cheap, Part Number: SU13238 $14.99

Where do you get those extrusions? Those are pretty sweet. Hardware store? They have special hardware for them?

it is available in industrial suppliers like Festo, Swagelock, Grainger, etc. I have a local distributor I knew from a previous job, so it was easy for me to get what I used in my install. Or for small pieces, your local machine shop may have some material left from a recent job.

I love threads like these!!! Keep up the badass work, man!!! :thumbup:

And don't forget ebay.

http://stores.ebay.com/8020-Inc-Gara...id=p4340.l2563

8020 is sort of the recognized leader in T-slot extrusion systems. They have an extensive catalog of parts for building things.

Coil on plug's finally installed & working.
Pictures when I clean the wiring a little bit. Right now everything is just tie wrapped.

I found to small issues, one of them is the hose of the power steering which is forcing the new coil to be bent like 15 degrees, Its not a problem since these coils are flexible. But it looks weird.

The second one is the plug#4. It is not tightened all the way in. Of course I knew this before, but now it became more evident. When I got the car the plug was installed in a weird angle, so I removed it and try it in the correct angle but it gets too hard to re-install it. I don't apply more force because I don't want to damage the head's thread. Any advise to solve this one?

Thanks! and thanks to the people that have helped with comments and guidance. It looks like the work under the hood in my car is pretty much done at this time, so we'll see if I can do a decent tune.

never tried it myself. There some cheaper versions you can find but that is the basic design.

I will certainly get one of these. Thanks for the info!

That's a pretty slick idea. Hopefully the threads are not too damaged already. Seems to be a fairly common problem with aluminum heads.

I like your thinking about the trigger wheel!

I had found those a while ago,

http://www.autosportlabs.net/Trigger_Wheel_Designs

I have even seen someone installing a 72-2 trigger wheel in the distributor and using vr sensors from a Rx-7...

My project has been completed.

After solving some issues not related to Megasquirt, but to my little knowledge of tuning, the car is working great now. Fires up at the first try and warms up by itself. Also the automatic Idle speed control is great for an automatic car like mine.

Here is a couple of views of the TBI and the new set up with coil on plugs. And dizzy finally removed!

Special thanks to Cygnus, I'm using your timing table with no modification other than the Idle w/shift area, since I assume your car is standard you don't need to get slightly advanced in that part of the table.

The final touch. I changed the buzzer that is installed there to another place under the glove box and put the Megasquirt where I can see the LEDs :flash: while I drive.

Isn't it nice to be rid of the distributor?

That's right, the auto timing curves are a bit different. I'm not sure how exactly though. I guess just tune it so that it idles the best. Usually that happens when the MAP is the lowest at a given RPM.

Great job!!

Oh yes, it was the best part. I always had a pretty big oil leak through the dist. but never looked for replacing the oring. No more worries about caps, rotors and wires.

You are the MAN!!! Nice work!

Congrats man! Great job!

Thank you guys! I am really enjoying the car and how powerful it feels. Megasquirt is a great product!

PS. My wife is asking me if I'm sure I'm not going to work in the car today haha.

I have to say that yours is the best execution of electronic timing control I've seen on this board. I especially like the pencil coils. I've always wanted them, but assumed they were impossible on these cars. Kudos again.

that is a sweet set up...its nice to be tuned
