Which ECU for the 18R-GEU? 2S-E, 5M-E, 22R-E?
|

Due to the relative ease of getting my hands on a 2S-E or 5M-E computer compared even to an old school 22R-E (from RT-142), i want to know if anyone has experience with using any of the other old analog EFI computers with an 18R-GEU?
I know either Blaze or BlackRA28 is using a 2S-E ECU, although i don't know how sucessful that has been. Im also interested in what AFM i should use. Looking at the 22R-E, 2S-E and 5M-E AFM's they all look freaking huge, so im assuming the 18R-GEU AFM was of the same ilk?
Any help, suggestions, pics, ideas, WHATEVER.. please post.
P.S. Eventually i will go all out with a DECENT computer.. for now im broke. So cheap is good

im using a 22R-E AFM with an 18RGeu ECU.
My beliefs are that any of those old schooler AFM's are the same unit (well.. 22r-e, 5m-e, 18r-ge) and i think these computers should be able to run it with some fiddling around. but dont take my words.. it all starts to become a pain when you are mixing and matching bits etc..
try and find as much standard gear from the motor of the computer u are going to run for it as well as finding the 18Rgeu standard gear, cos some parts are fairly-compatable and it could be worth trying alternates.

From my findings there a three different air flow meters produced by nippon denso for toyota. The 2tg one is smaller and possible different out put the 3teu, 3tgteu, 18rgeu, 22re, 2se and 5me all use the same size and out put from what I have found. These Air flow meters that I have mentioned also are the same size as many bosch meters and have the same out put and pin out. Nippon denso at this stage where licenced to produce these from Bosch, take a look they are identical to there bosch conter parts.
I would use a complete setup from the one car, try and get a 4 cylinder, less hassel in the wiring, try and get one with the 02 sensor if you are using unleaded fuels only as the 02 sensor will die quickly on leaded fuel.
The nippon denso gear used on other JAP cars such as mazda and nissan is not compatible, different AFM signal due to resistors use I think they go from 1.5-6 Volts toyta go from around 1.5-8volts and the pin out is different.
2se is easy to find, but all should work with a little tuninging.

I started out trying to get my 18rgu with efi going on a 2SE ECU. it didn't go so I eventually found an 18rgeu ECU still didn't go. I found that I have to get a different coil and ignitor to get injector pulse. I first was using a coil and ignitor from a 21re, then I ended up using an old 5me one that had a ballist resistor on it. I think it was the was I wired it up without the resistor that caused the problems.
So it cut this long story short I am quite sure that the 2se would have worked fine. I know that the AFM did because that is what I was using before I put on the 18rgeu AFM. worked fine but had the Idle mixture screw pre set from factory, unable to tune that yourself.
The 18rgeu ECU I have doesn't have a self diagnostics ability. and is different to those I have seen diagrams for. So in this case the 2se would be preffered. the long and short of it is the 2se is a 2Lt 4 cylinder engine, should have roughly the same fuel requirements as the 18rgeu and that is all these ECU handle. If I didn't have mine all working I'd properly test it for you. but as you should know my engine it shat so I have other things to worry about. give it a go.

Wouldn't the 5ME ECU have a sad cos its not running 6 cylinders?

2se AFM not having idle adjustment ( if you can call it that )? I have used 2se AFM and Mine had the screw adjustment. Pop the black cap onto of the AFM and look down into there is a screw with a Alan key to adjust bypass air.
By all accounts I think 2se would be the best.
I thought the 22re dizzy was a bolt in but if not try this.
As far as modifing the dizzy I have done it twice. I used a tone wheel off a toyota dizzy if you go around the wreckers and look at these sitting on dizzys find one that will fit nicely on the points shaft you currently have (ie the right inside diameter). These will pop of most dizzys with a big screw driver and lever it off. Grind down the shaft of your points dizzy where the cam lobes that the points follower sits on so your new tone wheel slips over.
Now you need to find a dizzy with the magnetic pick ups that will bolt into your dizzy like points almost(similar base plate and adjustment) early toyota ones do the job nicely. Bolt this down onto the plate where the points bolt on. Keep in mind you want full movement of the plate for vacume. With this bolted on line every thing up so the tone wheel is in line with the magnetic pick up when a plug is firing.
I then tack welded the tone wheel into this position and adjusted the pickup. And your done.
I was able to do this to a escort dizzy for about $5. The escort dizzy was fairly small so you should be able to fit it in. I did have to take a little out of the dizzy alloy wall to help the fitment though.
By the way when you bolt on the pick up you should allow some adjustment for the gap between the pick up and the tone wheel about 2mm.

Drilling out the little metal plug in the AFM is a common mod with MA61 Supra's. I expect it's much the same deal with a Camry AFM - there is a screw under there, you just have to get at it!

well then for the megre price of just over $100, i think i'll grab myself a 2S-E ECu and AFM... and while i'm at it ill grab the 5M-E ignitor and coil.
Thanks millions for your help guys

yes yes cam, im coming around tomorrow night. And i'll be grabbing all that gear off you. 
i'm also bidding on a bosch fuel pump from an Audi 2.2l turbo or porsche 928 (same on both) and the surge tank will come in around a week or two (after i do some measurements).
ECU and AFM - when i feel like it. Heck i may even splurge on an 18R-GEU AFM..... but i doubt it.
P.S. SSS autmotive suck - $250 for 18rgeu ECU, $100 for 18rgeu AFM

FWIW I still have a 5M-E ECU lying around somewhere. It's your if you want it. I may have a AFM as well, I'll have to check.

if you use the 2s ecu and loom can you use the 18rg electronic dizzy with the 2s loom? and will the 2s loom hook up to all sencors on the 18rg? i wil be going from twin carb to injection using an aftermarket efi manifold and what impendence injector cycle does the 2s ecu use?

Hey Celicaboy. I have 2 ECU for the 2SE and an AFM for it if you want. You can have them in exchange for some help with my engine??

Ist basically the same analog system that all early toyotas used. same type of plugs and all. Not sure what you mean about the 18rg dizzy. as all the ECU needs is a signal from the negative side of the coil(I am using the same wire out as the tacho) to give injector pulse. The ECU is Fuel only, early analog ECU's only controled the fuel, spark is still old teck.

I've only seen 2S-E's in early Camry's. You'll find 2S-C's (ie the carby model) in SA63 Celica's and ST141 Corona's.

I think you'll find it is multi-point. It's not sequential, but that's a different thing. Multi-point means there's one injector per cylinder, as opposed to single-point where there's one big fat injector in the throttle body (like old Magna's).

You are exactly right Norbie. I got confused. Mutli point does mean seperate injectors for each cylinder. I know the early EFI Camira's also have a single point injection system too.

Just remember, buy the right AFM for the right computer. The MA61 5M-E engine but the computer and AFM is different in the Cressida.
If i have stated anything wrong, i am happy to retract the statement.
Cheers.
