has anyone used any standalone engine management system (ecu) for our land cruisers? there probably aren't any "PLUG AND PLAY" standalones for our car.

i'm in the quest of trying to get better gas mileage and possibly turboing the truck too. just seeing what possibilities have been done and are out there!

i had a 93 toyota supra that i modified pretty heavily. i had an AEM engine management standalone, new fuel system (aftermarket 1000cc injectors, fuel lines and rail, dual pumps etc.) aftermarket turbo etc.

the supra is really easy to extract an insane amount of power from. and with the EMS (aem ecu) we were able to tune it really well (even with the aftermarket injectors), almost as good as a factory running car! i was able to get 26 mpg on the highway off boost out of a 750 HP car (on boost)

i know factory gas mileage for the supra is like 18/24 or something. it's pretty amazing to be able to get slightly better mileage on cruise with even big aftermarket injectors and fuel system.

this gets me curious as to whether or not i can do the same with the landcruiser. alter timing and play with fuel consumption etc.
all under carefully inspected tuning of course. (wideband and knock sensors- BTW do our cars 93 cruisers come with any knock sensors?)
i use it to daily drive and i LOVE this vehicle!! only thing killin me is obviously the gas prices and mileage...
so hopefully after i save a bit and can purchase all of these things, i can start the experiement.

would love to hear back from anyone else though!
 
Dunno, I keep tossing around the use of a Megasquirt II EMS but a little $$$ and a whole buncha work for something that is still working is kinda hard to do. (though I have told myself I WILL do it if my AFM goes bad)
 
Well you could have a not-so-crappy MAP sensor if you did mega squirt and then add a DIS 6...then a turbo.
 
i'm not sure about these trucks, but there are plenty of EMS standalones out there (tec 3, aem, motec, etc etc) and most of them will need their own custom wiring harness to splice into the factory sensors.

i know the aem you would eliminate the AFM all together and run on map sensors (any type you want- aem, GM, etc).

it's almost worth it, if you were contemplating on going turbo anyway because you'd need that amount of tuning.
 
Dont know of any plug and play..

It would be posible to make an adapter cable cut off plug from a junked toyota and gently put the pins from the 80's connector in it...

Hey you would know does the ECU connector on the supra look anything like the 80's If it is the same but wired differently you could just move the pins around the 80 series plug all but the MAP or MAF that you are replacing the AFM with of course..

FWIW Based on what I tried on a turbo car.. Had stock MAF.. Restricted power a bit.. Went MAP.. Power up but fuel economy when not on it not great and part throttle issues. Went with a big GM MAF meter left the MAP hooked up for AEM EMS boost control then added a wideband and ran it closed loop. Worked awesome.
 
Well I'd like to see this. A thread like this comes up every now and then and somebody inevitable states it's easy this way or that but I've yet to see it done.

And Kirk is running a chevy engine and I really don't see how that applies to our 1FZ-FE.

Also, I thought the 93 Supra's were running a MAF sensor and not the VAF the 93 LC has. If so they are totally different animals and expecting similar results between the two would be optimistic to say the least.

No need to freak Rick...

I was just saying that someone has attempted to modify the stock engine/tranny control systems and has had good luck with it. Kirk's LT-1 is still mated to the 442 as well as the stock full-time xfer case, so there is still applicability, regardless of the engine in the bay at the time.

Not freaking at all but lets stay on topic. We're talking about a stand alone ECU for the engine. Kirk's work doesn't apply.

In the past when this topic comes up there is great confidence in the beginning and then suddenly the thread dies. How about that guy in Asia building the SS manifold and using some sort of elaborate ECU. Posting almost daily and then nothing. I'm thinking he wasn't all that successful.

OK, I'm a skeptic, but show me a thread were someone has followed through on a stand alone ECU for our engine.

My take on this is people get over confident in a product's ability from experience of others as well as their own on other platforms and don't realize the task at hand. Safari had great success in AU with a Unichip but when it was installed on our trucks it over heated and burned the ECU out.

Tuning Haus has a 93 and if he can get a stand alone or piggy back to work on his truck it will be great as those trucks tend to run lean when boosted. But I don't think that solution will translate to the 95+ trucks.
