Yaris ECU broken??!!!!!!

[Yaris Hilton]

GM put out some lousy Oldsmobiles and Cadillacs with a gasoline V8 converted to Diesel circa 1980. Failed on the market and the GM execs concluded Diesels just wouldn't work in America.

Don't forget the Caddy 4-6-8 engine of the same period!

Oh, I haven't forgotten it. Actually, the idea is sound, it was poorly implemented.

GM had a history of coming up with radical new ideas and putting them into production after limited testing. The buyers were the test drivers. If you bought a GM model in about the third year of production or later, it was probably a good car. Heaven help you if you were an early adopter.

Isn't the Dodge Viper engine an old truck unit that was diesel converted to petrol a long while ago?


... Diesel eill only catch on if there is a financial incentive, and with gad at $3-4 per gallon, there isn't one.

If I lived in the US, I would have a V8 for sure, no point not. Fuel in the UK id about $7-8 per gallon. Sucks.

Nope that was a gas V8 modded into a (gas) V10. Yeah here in the US we still run around in V8s. We buy from the Saudi's who then give our $$$$ to the tererorists. Everybodys happy!
I just paid $2.48 a gallon last week!

They made a gas V10 truck engine that had the same block but different heads, I think. Dodge's truck Diesel is a straight 6 Cummins.

So, I managed to get an ECU for this 1.0 MMT Yaris, but the only one I could find came with the gearbox too!

£350 all in - that's like $550, so not on the whole too bad.

The ECU I wanted was: 8953052090, but I got one with the code 8953052100

I think due to the right and left hand drive markets, but I am taking an educated guess that the ECU is the same.

Is it?

... well anyway, the gearbox is really cool - it has three servos on it, and I logically guess that one is to disengage the clutch, while the other is to up-change, and the third the to down-change.

It has a standard clutch plate, and no torque convertor, so I can only assume that it works like a sequential motorbike manual gearbox, but with ECU controlled servo-actuation.

And then I though - well you can get 1.0 motorbikes, so this is basically a 1.0 motorbike powered yaris... well kinda, sorta not.

I was really impressed with the overall quality of this MMT unit, and as a biker myself, it's a pretty interesting piece of kit....

only problem is that sequential boxes arent designed to carry large loads well, so those servo's do a heck of a lot of work... and they are only the size of a childs fist or something.

They want the gearbox sent to them as they are not sure that it isnt coded - but I can't think why it would be - its the compatibility with the engine ECU that I would be concerned with.

Anyway, I was only helping out with this issue because we have good parts and breakers in the UK, and Greece is seemingly devoid of anything here. But it's no different to sending stuff between coasts in the US...

The authorised Toyota dealer in Greece strangely still don't know the issue for sure, and they are willing to fit used parts - work that out, cos I cant!
