My efi project

[sunnbobb]

well, he was right

[JBz]

With just the simple off and on cold start valve that I hope to use with the microsquirt which diagram would I be looking to use or none of them. A little premature but want to store it away for when the time comes?????????? Thanks jb

Picked up this pump brand new for less than $15.00 shipped. I don't have any idea what it originaly was made fo a air filter gizmo and other things I was thinking of just adding a sock strainer and canister filter like my bmwr1100rtp and getting away from the factory gl1200 ltd canister filter. But anyway its small enough that I make be able to alter my factory fuel sender top and hangit off it or If necessary make a new bung. Id like to keep my original sending unit I also have a external pump but at 90 psi and rather large. I guess this midget pump be ok 37gph 40 psi. It says for fuel injection only and came with a 40psi regulator jb

40psi should work ok. Injectors are rated at 43.5 and a lower pressure could alter the spray pattern, but it shouldnt make a huge difference.

As for the idle valve it would just be for the on/off settings. Im not using one so maybe socrace can chime in, but looking at tunerstudio you would just set the temp that it would be open until. As well as hysteresis which gives sort of a buffer around that setting so as it fluctuates a few degrees either side it wont open and close rapidly until solidly above.

I had some of this stuff roughed out earlier but had had to change things around to put this off-on start valve as the microsquirt wont handle a stepper.I had to have clearance for the water temp housing but got it roughed out where everything clears. I could have used the original press in nipples that were on the intakes but had a senior moment and pulled them out and tapped and plugged them with 1/8 npt plugs. Soon afterwards I realized what I had done. Thankfully I had some one touch push in air fittings that were 1/8 npt and a manifold that I could modify. The blue thing in the picture. Reading in the microsquirt thing I saw something I missed. They recommend a relay for the on-off valve. I plumbed the valve in reverse but I cant see where that should make a difference. I wanted a coldstart on mine. Yes it gets cold here. I hope it gets enough air for about 15-1800 rpm idle...........jb

Hey JBz, looks good to me, but what the heck do I know at this point in time. I will be trying the Jenvey manual air bypass methods fist, but if that does not work out well, I will go with something very close to what you are using. I also live in a place were cold starts are common, time will tell.

Sorry I have not had time to go out to SDS this week, an old sick dog and taking the wife in for a possible torn eye cornea, ate up the last two days.

Cheers

Not a problem Steve. Take care of Home first. Weve been fighting the bug. Jeannette got I bad me just a tad. Finally got to picknpull today before the next storm supposedly on Thursday and got some connectors for the injectors. I think I got a good deal on 4 new injectors motorcraft 195500-1280 ford probe 1989 but found out they take an oddball plug I think s696 not a ev1 type and at $20 plus a piece for connector picknpull was the place 6 dollars for 4 of them .Im quite a ways off but to study the tunerstudio I found out you got to have Your microsquirt talking to your computer so ill work on the wiring. My machine shop is too cold to work on the tank. My ultrasonic cleaner out there had a big layer of ice in it Take Care........JB

You can create a new project without connecting to Microsquirt. Just make sure you select the correct firmware version as menu options can change. You can flip through all the menus and get used to the overall feel of the program.

Hi JB,
How did I miss seeing your project til now? Anyway, I would say you're on the right path.
That fuel pump should work well, at the stated flow rate it should use around 3 amps, versus 6 amps for small car types.
One way to run the fuel return line is to replace the petcock with two fuel nipples, one reserve and other main fuel. Connect return to reserve and run main fuel to pump. No more reserve this way, but easy way to connect the return line.
The on/off iac is what megasquirt megamanual recommends. Your previous ford iac unit has to have a 160 cycle signal to work, just connecting it to a battery won't do it. Megasquirt can run either one fine, once you program it.
Will be watching progress from now on!

Slowly getting back to it. Had to put some steering brakes on the crawler and fix some hydraulic leaks and some other important things first. But anyway before going brain dead I did some exploration on the Engine itself as I didn't have a lot of history. I welded a new motor mount on it . The water pump is obviously wore out and I could tell it had been running on tap water. I better take the heads off and check things out. The water jackets looked like a hot water heater heating element and the bottom of the heater. Full of crud and calcium from running on tap water. My guess looking at the bores it had a slow head gasket leak and the po just kept on filling it with water. #2 looks a little iffy but Ill go with it. Looks like the oil had never been changed.The rockers are and cam are a little rough. The hydrauilics are coming out and Ill be machining the stock 1200 heads for solid lifters. Im hoping ill be able to polish the cams or take them down the road to Erson and get their 2 cents. The 1200 FI engines take their own cams. That's where its at of today January 28 2014...........jb

Some pictures. A tank I had cut years ago to do a Powerholic mod has become the donor tank for now. Picture of the coolant sensor. Decided against the GM coils for now and hopefully this Kiss ignition setup will work.. Dyna 3ohm coils and 1100 ignitors and suppression wires to keep the brain calm. Reworked the 1200 heads for mechanical lifters. Freshened them up and new head gaskets. This engine maybe marginal.. filthy oil , a lot of crud in the water jackets and appeared to have run with a bad head gasket for a while. It what I got for this test project for now......... Still got a long ways to go.........JB

[joedrum]

I sure would like to get a look at the reworked 1200 heads jbz ... been using those metal tools again

[JBz]

Basicaly I just plugged the 1200 oil passage where it used to go into the hydraulic lifters. There by the screen between the head and hydraulic lifters. Then I drilled a new hole that matched where the gl100 gl1100 oil comes into their rocker arms. Actually I drilled the hole First so I could see that I joined the passage. I used 1000 1100 rocker assemblies and bolts.The only thing is the cam seal metal covers wont cover all the plastic cap on the left rear and the right front timing belt inner cover has less holding surface. I had to go with the 1000 or 1100 valve covers as the 1200 wont fit any longer but the valve covers don't stick out as far as the stock 1200s. As far as the chrome octopus looking thing by the intake manifolds goes I just cut the fittings off and pressed in some steel and welded them up and popped them back in.I could have opted for 1000 or 1100 heads with bigger intake valves but decided to go this route......... The 12000 hydraulic heads are fine but they really need timely oil changes and over reved Ive seen them break rocker arms. Of course that can happen on anything.... but should be able to rev better ..... 10 pages on how to repair and shim the hydraulic tappets isn't my thing and these didn't look good at all and ate the lobes on the camshaft. I found another set of cams and polished the lobes and followers.....jb

[joedrum]

thanks jbz I will log this as doable now for consideration ... I actually have a setup to consider this on

[JBz]

still working on things. This takes better computer skills than I have. Trying to catch on. Lots of new lingo to me . You would think that firmware would be a hard belly in a bikini. No its a program. Im going a different route that might make it easier for me. A 36minus 1 wheel I machined .. might look crooked due to camera angle..jb
