Hello,

I have received the present all the way from Japan... :eek:

It is the direct plug in for my 1992 Land cruiser ECU wiring harness. I thought I would check here first with you guys.

My goal is to make a plug and play Mega Squirt system, and have the parts now. I'm ordering my board today to finish and test it.

Anyone else interested just follow this thread.

What I need first is to establish which OTHER year models this connector fits. I need guys to take pics of this list of ECU, (engine control unit, or computer) and stick it in this thread. Pics must be looking INTO the ECU LIKE THIS ONE....

I could look it up myself, but thought I'd just have it posted that way anyone could figure it out. Here goes.

Year: 1992 see attachment (let me know if I need a bigger picture)

edit; I will be selling this when I'm done as I am installing a GM V8 in mine in the next week or so.... I'm just doing this for everyone else, and this is what I do for a living.

This is from a 96 80 series (LX450). There are 4 ECM connectors, as best I can tell (from the Wiring Harness manual) the following should be the p/n for the connectors:

E4: 90980-11390
E5: 90980-11391
E6: 90980-11408
E7: 90980-11392

Got that plug here. ( see below) If you don't have emissions to worry about I'm almost positive that it will work fine, 1996 and up have to pass OBDII emissions. However, I found that I could build a box that with those part number connectors will allow me to make a plug and play piggy back using : PERFORMANCE MOTOR RESEARCH LTD : products, which for the turbo guys, would allow the changeover to speed density, have timing control, and still pass emissions via a factory ecu.

Nifty! Thanks for the part numbers. I wonder if I could get a dealer to order them? (willingly)

No problem. :)

As you know, each plug will have a 5 digit number on it somewhere. That is the last five digit number of a ten digit part number.

First five numbers will be: 90980-xxxxx (x's being the number on the connector).
 
Howdy! Will it do any good for us S/C guys? John

And I say this as politically correct as possible... heck yes it will...

You can even go about 100--120% larger on injector size. Drop in a Walbro fuel pump and wire the pump for full time 12volts, if it has a two stage set up.

The MAP ECU2, actually can also drive two additional injectors as well as other stuff.
 
This is turning out to be good!!!!!!!!

I'm not so sure about that, beno. Note that the connector Wayneosan is talking about is the connector that solders onto the PC board of the ECU and not the harness connectors. It certainly would not be considered a field repair for a tech to open up the ECU and replace that connector; hence I'm skeptical if you can get it through Toyota. I'm impressed that Wayeosan has the contacts needed to even get samples sent to him.

My bad. I think you are right Dr. Ferrin. I can't find anything for the above.

Note that most 1995's and later FZJ80's came with A343F transmissions, which is an electronically controlled transmission. You gonna program the Megasquirt to do that too? The ECU's in those model 80's has a second PC board piggybacked on the first for running the transmission solenoids.
 
That's number two on my list. Being that I know for a fact now that I can get the correct "header receptacle" for the board, I am confident that most people will be able to get away with a plug and play piggy back. I can also get the plugs that fit the receptacle, not from Toyota.

That's great if in fact it does have an external controlled computer for the transmission because I might be able to make that work with a stand alone. This is the very next line down on my to do list.
:popcorn:

anticipation is killing me.
 
I'm in for a plug and play solution for a 96. I've got a MAPECU2 in my 4runner and it works well.

Any chance you'd be doing anything like a FI fueling augmentation kit like Gadget does for the taco/4runner crowd?

That's exactly what I was thinking, but at both shops I work at, the LC's are not their focus, so I'll probably just do this on my own. We have a dyno at one shop, and various AWD dyno's in the area, so getting base maps and testing done will not be a problem. I'm going to "try" to have the MS2 PNP for the 92 Land Cruiser ready for the next North Texas meet in a couple of weeks.

Yes, URD is a well talked about distributor for MAPECU products, by the owner of MAP ECU.

I did install a MAPECU2 on a twin turbo Lexus ISF and it worked great. Also installing one in a week or so on a 1UZ Lexus IS300 swap. Those weren't plug and play, but they needed it as the ISF made like 550/500 and the IS300 is supercharged with a built motor, probably with similar numbers.
 
Well well well... seems here like we got ourselves a trouble maker....

Built the PNP set up from the B&G micro squirt.

I got everything to work including the MAF, on the truck. I can tune via map/maf combined calculations!! WOOT!!!!! Actually, I lied. I have to build a small chip that will drive the factory idle air motor. BUT IT WILL HAPPEN!!!!

I need to scope and set the trigger offset and I'm pretty sure that means I have a plug and play COMPUTER!!!

Been talking to the guy from DIYAutoTune.com Megasquirt Kits / Assembled Engine Management Systems, Wideband o2 Sensor Systems and tuning products and if there's some interest he'll do a board and box set up for us. Go poke around the site and check it out. That header receptacle actually fits lots of other cars, so it wouldn't totally be for us, but hey I'd feel special.

There's even blue tooth logging? I think? That's a new one even for me, so I'll have to dig into that some. That would kick butt, well, at least it would be cool.
Just need to get one on the dyno to get some results. I almost guarantee there's more power in there, as well as slightly better mileage. Not to mention, when you install a turbo or supercharger, you'll have complete control.
 
Since this box is for pre OBDII, no. Mine is a 1992 truck. Otherwise, it will pass sniffers and all other inspections assuming the engine is calibrated properly. I have to buy some credits from Toyota for the scanning software to help tune my Supra, so when I do that I will have access to ALL years of Service Manuals and EWD's and I will do a year by year comparison to find out exactly what years this will plug into. The DIY Autotune PNP 76PIN Nippondenso connector fits later model ones according to the other pic up top, but I'd need to see what else it's got to be wired up. Those would be OBDII cars and only guys that don't have to worry about emissions would benefit from having an aftermarket ECU. Like I was saying elsewhere, the MAPECU2 would be the perfect alternative for aftermarket control whilst still having to pass OBDII emissions. Fuel, timing, addl injectors and about 4 leaps and bound more sophisticated than any other piggy back. I'm pretty sure I've used them all at one point in time. I've seen a lot that's for sure.

Of course, if you wanted fancy, here's a pic of the wiring harness I built for a Bonneville Land Speed Ferrari. You don't want to know how much that cost.

Pro 18 M&W box

and lots of other goodies.

Did anyone ask jgwinc if his emange controlled the trans? I think he is the first and only person to run a standalone. I think he would be a good person to get info from.
 
Not a fan of Emanage.

I'll try to finish this project this weekend.

I've got about 40 hours in research, and about 8 hours building the Mega Squirt itself. I'm done with the research. I'm done with the building for now. I'd like to expand on it some though. I might set it up so that the fuel pressure VSV output can be used as a boost control solenoid and much much more.

I have bigger fish to fry this week, so I won't get to it until the weekend.

Just trying to do this so anyone on here can follow lead. I'll post up docs as soon as I test. Who knows, maybe it will be a fuel injection sticky... :clap:
