jim kelly's 1975 914 suby build, water pump housing and header interference ??? Options

[Chris H.]

Yeah the MS should work great. I just bought a Megasquirt 3 system. Should be here tomorrow (IMG:style_emoticons/default/chowtime.gif) . The 2.2 and 3.3 are easy to set up.

So Jim.... (IMG:style_emoticons/default/idea.gif) ...you gonna use all 4 of those 2.2's (IMG:style_emoticons/default/biggrin.gif) ? I need something for my Vanagon.

[jimkelly]

mine will be NA. baby steps for me.

i WAS thinking one engine at a time but who knows (IMG:style_emoticons/default/smile.gif)

i have one known good, one known bad, and two unknown condition, mostly for spare parts. pretty certain the one 5spd trans i have is good.

hopefully i will have some sort of update in the next month or so (IMG:style_emoticons/default/popcorn[1].gif)

got gm iat sensor, gm clt sensor, on order. plan to tap the pcv valve hole for the iat and tap the coolant manifold for the clt senor.

seems like aem uego is a decent buy and about $100 less than innovate lm2.

I have this one. I like it a lot, I have it plugged into my boost controller. Really easy to read and pretty bright.

[jimkelly]

pulled intake and coolant manifold off test engine. made blanking plate for the IACV and plate to mount vw coil. ordered some m6 bolts to mount it all.

i assume next to coolant sensor is a sensor for a coolant dummy light (one wire)?

what do you guys think about drilling and tapping the pcv bung in the manifold for the install of a iat sensor. or should i just add another bung for the iat and keep pcv valve in place?

There are 2 temp sensors. 2 wire for the ecu and 1 wire for the gauge.

You need the pvc valve.

Other note, I thought MS3 could be setup for different sensors. The benefit is the Subaru sensors already bolt in and fit the harness.

If you are not boosted then the iat can go anywhere. Most factory locations are the airbox after the filter.

[jimkelly]

my coworker suggested i put the iat sensor thru the iacv block off plate. sounds reasonable.

the nice thing about gm senors is they are cheap, like $15 $20 new each. iat and clt.

i'm not using subaru harness, just microsquirt harness to sensor pigtails.

[jimkelly]

as for pcv removal.

i have one breather on each head. shouldn't that suffice?

fwiw - the thread on subaru iat and clt sensors is M12-1.5

[jimkelly]

my latest confusion. seems coil does not line up with cylinder location on engine.

http://www.msextra.com/doc/pdf/html/Micros...are-3.4-62.html

ej22 clockwise starting front left, 1,3,4,2
coil 2,3,4,1

i thought banks mattered with batch spark?

i realize most won't understand my question, in fact i am not sure i understand it myself (IMG:style_emoticons/default/sad.gif)

[914forme]

You only have 17 possible combinations. (IMG:style_emoticons/default/confused24.gif)

Yes that is me being a smart arse.

And four of them will work, but we will make this easy as we can.

Spark plug 1 goes to coil plug 1

Spark Plug 3 goes to coil plug 2

Spark Plug 2 goes to Coil plug 3

Spark Plug 4 goes to coil plug 4



That solution makes the wires cross over each other. What a mess so this while logically more strain is easier on the eye.

So Spark plug 1 to coil plug 3

Spark Plug 2 to coil plug 1

Spark Plug 3 to Coil plug 4

Spark Plug 4 to coil plug 2



Much easier with coil on plug, or individual coils.

BTW, re-lable the coil to match your final working solution.

Hope that helps if I missed the question o the description, let me know I will modify my post not to steer anyone wrong.

[jimkelly]

stephen, very awesome, thank you! jim

[jimkelly]

i am being told that this is the firing order.

[914forme]

Mount the coil upside down. (IMG:style_emoticons/default/w00t.gif) (IMG:style_emoticons/default/confused24.gif)

If you make your pickup 180 degrees out it also has the same effect as mounting the coil upside down. (IMG:style_emoticons/default/screwy.gif)

Your now running with crazy, the key to the entire thing is pretty simple you want to fire on alternating coil packs. In a 6 cylinder you just add a third so coil pack 1, 2, 3, 1, ,2, 3.

V8
1,2,3,4,1,2,3,4

V10
1,2,3,4,5,1,2,3,4,5

V12
1,2,3,4,5,6,1,2,3,4,5,6 or 1,2,3,1,2,3

Dual plugs you just run multiple coil packs in redundancy.

1a&1b,2a&2b, you get the idea.

This is all wasted spark setups, once you go with sequential, things get so much easier (IMG:style_emoticons/default/av-943.gif) Then you have to figure out the logic to drive the coils in the order you want them to fire. I am now taking this beyond your question and sorry for that.

Maybe I should do a mini school on EFI logic, and wiring. We are getting into so many engine combinations it is not longer just a discussion type-IV, and -6 engines. Even -6s with twin plugs makes things just a tad worse. Luckily your Subaru 2.2 is about as basic of an EFI engine as you can get, so a MicroSquirt unit should be pretty simple. Being said we have not gotten into doing anything the EFI input sides.

Back off my mad ramblings the firing order of the engine 1-3-2-4.

In your drawing you have the order correctly as that is the firing order, but your cylinder numbers or as I called spark plug is not.

1 in your drawing is cylinder or spark plug number 1 hook it up to coil side 1/4
2 in your drawing is cylinder or spark plug number 3 hook it up to coil side 2/3
3 in your drawing is cylinder or spark plug number 2 hook it up to coil side 1/4
4 in your drawing is cylinder or spark plug number 4 hook it up to coil side 2/3

Makes it any clearer than the mud it is?

[jimkelly]

stephen

your last 4 lines are GOLD, pure gold : )
except for cylinder 2.

got my coil mounted
thanks

[914forme]

Fixed that is what I get for copy and pasting my work load (IMG:style_emoticons/default/biggrin.gif)

[jimkelly]

thanks - big help (IMG:style_emoticons/default/smile.gif)

[jimkelly]

trying to remove my trans tail cover to convert to 2wd. but roll pin came put but shifter piece won't come off, rusty. also does this piece normally have protrusions where the roll pin goes in. see last pic.

nevermind, answered my own question, there was more roll pin left, outter section.

might have to use cut wheel and angle grinder to remove this piece though (IMG:style_emoticons/default/dry.gif)

gonna try soaking with pb blaster first.

need to get a puller to remove 6/7 crank sprocket, so i can install 36-2-2-2 sprocket.

seems spark plug wires go like this.

[jimkelly]

guys, how to i order and make spark plug wires for subaru spark plugs and 1999 vw bug coil plugs?
