How far are you from Missoula?

Gnarls.

Still kicking in the 90s here. You can go to walmart and get a window unit good for 500 sqft for $100

Gnarls.

About 3 hours, maybe 3 1/2 with a headwind.  Google says about 197 miles.  We are on the east side of the rockies though. Completely different culture than Missoula.

[H8PVMNT]

In fact it's better if you don't say the word Missoula here.    I found out the hard way because I used to live near Missoula.

Memorial Day Wkend,2015, 85' Xtracab 22RE 5spd 4:10s 33s stock exhaust manifold after market Cat, Hushpower Muff, I got 25mpg going from Hermosa to Bishop fully loaded for a weekend of Wheelin'. The best so far for me.

Even roadies get into debates about torque.  Kind of reminds me of all us guys on here and our cam and gearing discussions.  There is a legitimate possibility that a guy in good shape may have more torque than a tired 22r.

That's pretty good MPG.  I averaged between 19 and 20 with my 1985 22R, 5-speed, 33s, 4.10s.

What?

[Gnarly4X]

I had a bad dream last night.  I could not get all the connections, hoses, injector plugs back onto my engine after dropping it back into the engine bay!!

Since I did NOT label all the wires and tubes, I'm starting to have some anxiety about getting everything properly connected.   

Is there a way to verify all the connections to the sensors, injectors, hoses, etc, etc. ??

I know there are diagrams of vacuum hose connections?

I haven't done a ton of research yet.

Any help will be most appreciated.

Here Gnarls:

The color of the plastic plug does not matter... You will have two injector plugs with white/red and yellow wires - those two go to cyl#'s 1 and 3.
the other two plugs will have white and blur wires.. those two plugs go to injectors # 2 and 4.

Hey Gnarls...  Thank you for the info, I had some anal pucker thinking that I didn't label those 4 wires!

You're an awesome dude!

Gnarly, if you got the injector plugs mixed up it'd be fine. The 22re's are batch fire, meaning all 4 fire at the same time every time. But typically the front two are taped together and the back two are taped together. Also, have you pulled the wiring harness apart to solder all 4 injector grounds? Toyota crimped them together and it can cause problems if they fail, when they fail they typically take out two injectors. Or if it's far enough down the line all 4.

What a minute...  So all 4 injectors fire fuel at the same time? No wonder I only get 24 MPG!!!!

Holy Crapity!!!  Geezz.... how far into the wire harness do I need to look?

Gnarls.

[Mudder]

I wanna say not very far, maybe 2 feet or so. But it's hard for me to judge correctly since I had my whole harness out of the truck for repair and wrapping.

Yup, a 22re is batch fire. Which does suck in a way but these old ECU's aren't capable of much more.

Geezz.. I think I'd rather get beat with an ugly stick than have to get into my wire harness!!

Is there any add-on module that you could use to change them to individually fire? I saw something from LCE very i think it was for the plugs

You could in megasquirt. I wouldn't buy any stand alone from LCE. Megasquirt is typically half the price or more unless you buy their fully assembled PNP ECU.

[Gnarly4X]

MegaSquirt....... I don't think I have enough mega in my squirt to be messing with that!

Most of the wiring harness falls into place and has the connectors appropriate for the sensors/injectors.  The vacuum lines have a diagram on the inside of the hood or you can locate a factory manual for info.  I downloaded the pdf version for my 85' from the internet, but have the factory hard copy too.  If your hood doesn't have the sticker of the vac lines, you can order one from Toyota.   

[Slabzilla]

Hey Gnarls, you'll probably find a couple of connectors that don't go to anything under the intake, just look inside the plug and if it's dirty it's probably an unused one.  Just my ongoing experience.

Zippo ran a megasquirt on his 22R-ze (supercharged) it was pretty plug and play. He didn't have to do any tuning before starting it up. I think it canes pre programmed with a base map. You can of course reprogram them to you own perameters.

That what I meant with the megasquirt PNP. It's a fully assembled ECU that you can load a premade base map onto that'll go onto any wiring harness from a 22re from 85-91 UNLESS you have an automatic tranny.

[OTO Phil]

And it'll get rid of the all at once fuel injector system? Anyone seen a dyno result of power difference?

[Mudder]

Highly doubtful as the person who did the write up on installing megasquirt into his 22re kept it as batch fire. You'd have to figure out when the injectors fire during the timing cycle and program that in I believe. IMHO it isn't worth it, batch fire works just fine on these old engine. If you really want to make power do an engine swap.

Here's an article that talks about converting to sequential injection. http://www.yotatech.com/f116/22re-simultaneous-injection-explain-please-160477/index2.html
