I'm 99% sure those are NOT UCF11 drawings.

Attached are.

hmmm dunno myself...
...the guy who sent me the files was seemed sure of what he thought they were.
any idea what you think they are then?

those files youve posted are micheals? from here:
viewtopic.php?f=59&t=1264

(ps i love aftermarket ecus!)

Yeah, MWP's files (the excel spreadsheet it what I did to wire mine up).

MWP confirmed on lextreme that those originals ones weren't UCF1x

hmm ok, thanks for the tip-off

ill delete the model reference in the thread title until someone can come up with a definitive answer on what this diagram relates to

cheers

It may be a UCF20.

One giveaway that its not UCF1x is the Fuel Pump Controller. UCF1x's just run a FPR and Resistor.

But that big hexagonal shaped plug is in the UCF1x, so UCF20 is a possibility.

Same ECU plugs as a 1994.1 to 1995.5 UZZ30/UZZ31 Soarer - the limited run ECU model without the cold start injector

2nd Gen 1UZ's have 8 injector controllers too (I'm led to believe).

And thinking about it, UCF20's run a hotwire AFM

lucky for this unknown diagram, couldn't find a 34, 22, 16, 28 ECU pin out. My motor is supposed to be early celsior, has bits and pieces to agree with that.

ECU number on Toyodiy for UCF20 is 89661-50240

ECU number on my ECU is 89661-50170, which is one of the two numbers listed on Toyodiy for UCF1*, the other number being 89661-50102

The first images came from me, they even have my handwriting on them, haha.

They are UCF11 diagram, I got them from a toyota dealership, scanned them at work, and them put them on the net for everyone, they are 100% 1uz-fe engine diagram, it's for a Toyota Celcior (sp?) 1992. and yes, .. they are genuine.

sorry but cant help cracking up to find these here, marked as of dubious origin, .. really, really, funny.

lol... didnt say dubious, just reverted to 'unknown' due to debate on model type

still intersting ten, the differences in diagrams for the ucf11

hehe, dubious was an interfence taken :p

There are differences, in what I consider non-core design elements such as pin config, and routing of wires, and colour of them, the core system seems to fairly consistent.

One thing I noticed when working with the diagram is that the wire colours do not all match up, but the pin location, and final location (where ever the wire goes), does in fact match. It's as if they sometimes ran out of wire and just replaced it with a similar type but of a different colour. So for example a red coloured wire with a black stripe, might have a substitute wire which is green with a yellow stripe for no obvious reason.
