ahh.. yes indeed.

Well, practically everyone knows that anyway...

No analog EFI on trucks either. only celicas.

TCCS first arrived on the 5M-GEU in the 1980 Celica XX (Japan only).

Its American debut was (I believe) in the 1982 Celica Supra (same as XX, but American market name).

 

one interesting '85 exclusive has nothing to do with the EFI system itself.

1985 was the only year you could get a 22R-E backed by a G52, since the G52 was used exclusively on solid axle trucks from late '83-85, replacing the L series gearboxes.

If you own Back To The Future Part III, or the Box Set, go to the scene where Needles pulls up next to Marty and Jennifer. Take a good close look at the shift knob as he puts it in neutral, moves side to side, then reverse. Also, what W56 makes a clunking sound like that when you put it in reverse? none that I know of.

You can clearly see that it's a G52 shift knob, not a W56.

 

No it is not a joke. I asked about the electronic fuel injection not the block or heads which I already know. So what is so unique about the EFI on the 85? Care to enlighten me?

 

its just the simple fact that you have the oldschool truck, with a solid axle.
The simplicity and strength/reliability of a solid axle, paired with EFI.
thats the basic thought process that began this thread.


OP correct me if im wrong

 

okay then... here it is.

In 1985, the TCCS Test Terminal began a phase-in to a new multipurpose connector known as TE1. Throughout the year, however, some models were equipped with the older connector, known simply as T. This T connector was not multipurpose and was only used for resetting ignition timing settings within the ECU. The new TE1 connector was relocated to the fender or bulkhead area, depending on configuration. The old T connector was located in various different places in different models. Since the VAST system was used on the 22R-E as well as the 4A-GE (as opposed to ESA), some FF applications existed as well as the more traditional FR configuration. Thus with a transverse engine, the TE1 connector was typically located on the bulkhead, and conversely located on the fender (intake side) for longitudinal configurations such as the 22R-E and 4A-GE in the AE86 Corolla/Sprinter Trueno/Levin.

In short, some '85 trucks and 4Runners ended up with the old T connector. The T connector is only found on '85 22R-E engines. From 1986 onward, all 22R-E engines used the TE1 style connector, which is mapped into several other sensors, allowing it to be used in a multipurpose fashion.

acronyms:

ESA: Electronic Spark Advance
VAST: Variable Advance Spark Timing
TCCS: Toyota Computer Controlled System

 

scuba, you're almost certainly exactly right about the original intent of this thread...

it was about the third or fourth post that somebody mentioned the '85 EFI system being unique, and I knew I'd read about it somewhere, and sure enough, Toyota Motor Sales U.S.A. has a "white paper" on it. It's only about five pages long altogether, and describes the difference between the ESA, VAST, and TDIS ignition systems. The only real difference I could pick out is the T versus TE1 connector patched into the ECU. You'll only find the T connector on '85 EFI engines.

And that is what makes the '85 EFI system unique.

 

lmao sorry I thought you meant what makes the 85 unique in the sense that it has a sfa and the 22re you should have mentioned what makes the 85 "engine" unique that would help get your question answered...

 

Blah blah blah

Hell, it was the last year of the straight axle and one of the first 22REs...a great combination for a trail rig.

And no, it is not rare, at least not in Alabama. I picked one up that was running last year for a grand...all it needed was new rear seals and some brake maintenance.

 

I mentioned EFI electronic fuel injection. Cannot get any clearer than that

Was the Celica XX not the 1G-GEU (hence the XX = 2000cc)

no mention of the 22re n there.

 

but the US market Supra...

22r engines were still in 4runners and trucks till 93. the first year to have EFI in 4runners and trucks were the '84 4runners. then '85 trucks. then '86 4runners and trucks came with IFS. rare = yes.

 

but were they 4runners in 84? or trekkers?

 

late '84 4runners. my friend has one. he got it for $2500 already lifted 5". with brand new 35" wrangler MTs.
