Never realized how much stuff i actually needed for this project till now.

Main harness



Ecu Pigtail(1998 GLE)


Junk Ecu (1997)(Thanks to DJ42o96maX) The freaking post office lady put this in my freaking mail box and guess what i cant get the damn thing out!! I had to go to work today and of course the lady gets here pretty much right after i leave to go to work so i will have to wait till tommorow to get the damn ecu! Its funny but its not at the same time.

The following are some links and diagrams i found useful for this project

LMAO....

BTW Nice Packaging.

 

And my free laptop from my brother just got her 2 days ago



500mhz 64MB Ram 11gig hd cant complain though it was free!!!Obviously this has one function and one function only EMANAGE!!!!!!!

I know the ecu harnesses are optional but it will hopefully make for a easier install

I will be taking apart my junk ecu tommorrow night and soldering it all up and will take pics of the process

 

lol yeah i thought i could squeeze it through if i took off the packing didnt work lol

 

damn i wish i had a pigtail.... i have a feeling i will be on my back for a few hours very soon

What kind of connection are you gonna use lock? I'm just using two DB-25 pin connectors.... I already wired the Emanage harness but have yet to start the ECU

 

Um no way. But i may be trading the s/c for a 2001 ae.

 

But to get back sorta on topic...


I have a EU sitting in my closet along with an 00VI....maybe I should put them in...

anyone want to make a plug and play adapter for me?

 

Holy $hit. I am too drunk to edit this thread now, but when I get to work in the morning, if you toolbags have not cleaned up your own posts, I WILL, and there will be bans served hot and juicy to go on the side.

Any $hit-talking after my post gets an immediate ban.

 

I would love to actually. Just supply the harness, and ECU adapters and maybe a little cash and Id love to. I want to do it for mine, so I might as well get one down and itll make my life easier! Pm me man.

Still here lock(op)? Keep us updated.

 

haha wtf.^

You know now that i think about it, it's probably a really good idea to use the pigtail from an ECU cuz it took me like 2 hours to do the EU harness sitting at my desk....

anyone got one for a 97GLE auto

 

so you guys are pulling the female end of the connector (out of the ecu) and just using it like that? lets see more pics! Thats a crap load of soldering huh.

 

I talked to bigpulve, and I am going to make a plug and play harness for him for the EU. If I do well at it, I might do some more if anyone is interested. Basically, you will plug one end into your ECU, one end into the ECU wire plug and the other into the EU.

 

Lmfao. wow i didnt think my eu install would cause that much of a controversy. 3 freaking pages wow!!! well 1st of all lets see the extended rev limiter itself is well worth it appose to lets say jwt. how much does a jwt even go for now??

All my life i have been messing with computers. I pretty much switched my hobby from computers to my maxima. So naturally why wouldnt i want pretty much full control off my ecu?? Its in my nature. and i get a laptop in my car. how sweet.

I contiplated getting a apexi and it just didnt appeal to me. i really want to rev to 7k so that was out of the picture. smt-6 im not to fimillar with and there isnt a good write up on it like dandymaxs.

I took apart the ecu right when i got back from work today. i will post pics later on in the night

 

very cool. i'm looking forward to it. Im going to get one of these eventually and definitely would prefer to do it this way rather than splicing into my already tortured harness.

 

ok, i'll bite, if bigpulves turns out good and the car starts i'll be your next customer.

 

man ol man. well i realized one thing tonight. that i really suck at soldering. i have probley done like 15 wires in two hours. Defently not a walk in the park. I had to redo 3 pins though cause the place i was suppose to solder at totally snapped off pretty much into the plastic. so i had to fix it. some before and after pics





Pretty much i used the heat of the soldering gun to melt and pulled the pin out then i put the pin back in to recessed it back a little bit so there was something to solder onto. that alone took me like 45 mins. But i think i messed up my tip of the gun by doing that cause now its all messed up and demented looking. I know the pics are not the greatest but i think i got it acrossed WHEN YOU DISSASEMBLE THE ECU DONT ROCK IT BACK AND FORTH TO GET IT LOOSE!!!!! Dumb mistake on my behalf!!

 

soldering gun


Think i am going to call it a night and get a new gun tommorrow and go back at it

i finally read though this whole freaking thread. Man alot of edits. Would of been intresting to see the **** talking


Coremanx you are defently intitled to your own opinion. If you dont think a EU is worth the time or money unless boosted then thats cool. But to me its obviously worth it and no one is going to change my opinion. and whos to say next tax season i might just get a t3/t4 doubtfull but i would defently would love to.

Granted a window switch for my nitrous is realtivly cheap. I will use the EU instead. and will be able to monitor my car under spray which is a safety and not blowing my engine up thing. I think of it as a insurance policy on my engine if anything.

But in all honesty i could get the best mod out there that gives me 100hp gain or what ever. That wouldnt be the only reason why i bought the mod. I love a challenge and to learn the EU is a challenge and yes i will defently learn. Knowledge you cannot buy. But you can pass it along and help others down the road. It is what this whole forum is based off of. So in reality im not just Paying 600-700 dollars for just EU but accomplishment after a big project is priceless.


Just one last thing before i call it a morning\night. You should run that opinon past dandymax that would be intresting.

 

Is that a Radio Shack soldering gun? What's the wattage on that thing? Ideally you'd want somewhere around 15-30W when working with the ECU, so as not to burn the damn thing up.

Then again, you're working with a junk one (I presume) so it wouldn't matter that much.

 

its a wal-mart 5 dollar brand. i bought it to solder up the injectors from my 00vi swap. its a 30 watt. im going to go to radio shack and look around to get some ideas to make the solder job easier. defently going to get some aligator clips for a 3rd hand. i should of done that in the first place... what the hell was i thinking?

 

Thanks to those who edited their posts and reported this thread.

You guys can disagree on whether this is a good/worthwhile mod, but try to keep it clean.

Just don't let it get out of control today, as I will most likely be drinking again tonight, plus my Mountaineers are on ESPN, so I won't be on the org tonight.

 

I have removed the ecu header connector off of ecus from the A32, A33 and A34 chassis series and there is no need to use a soldering iron.

Less than five minutes with a small set of side cutters and you are done

 

You have fun sir...

No chance of me burning down my car....

Lock. Looks like its coming along well....

 

Lock, it's cool, we all make mistakes. Put it this way, it could be worse...you could be doing all that wiring inside the passenger's footwell of your car

 

Are you "tinning your wires" before you try to solder them to the pins?

Quite often, I will place a small glob of solder onto the pin. You then place the tinned wire on top and apply heat to the wire until the solder on the pin and the tinned wire solder flow together. You want your connections to be smooth and shiny. Dull, grey ones are referred to as "cold" and will break easily.

Do not apply too much heat or the solder will wick up under the wire insulation and make the wire prone to breaking.

It goes alot faster if you approach it in assembly line fashion.

1. Cut all your wires to the correct length
2. Strip the ends off of all your wires. A wire stripper with a length gauge really speeds up this process.
3. Tin all your wires.
4. Cut all your heat shrink to the correct length
5. Slide heat shrink back on all the wires far enough so that they do not "see" any heat from the soldering.
4. Clean pins and apply a glob of solder to each one that is needed.
5. Solder wire to pin. Do one entire row at a time.
6. Before starting next row, apply heat to shrink tubing.

 

Hmm.. the EU is not worth it for N/A....

Let's see, at minimum you get:

-extended redline
-15-20whp gain with timing and A/F tuning
-Air/fuel auto tune (ie closed loop tuning operation)
-2-step launch limiter for the track
-flat shift (ie power shift) limiter
-very good datalogger including WBO2 input
-ability to control all kinds of relays, devices such as fans, variable intake switchovers etc
-ability to compensate for different injectors, larger MAF's, even remove the MAF altogether and run speed-density

-Net result of all of the above, depending on mods on the car, can easily be half a second off the 1/4 mile time and a couple of MPH in trap speed, probably more if you didn't have VI control before.

And all of this for about $500 used or $600 new. Nah that's not worth it at all.

 

well thats that for all trash talkers, back that

 

 

+1

This is an interesting project. I'll be following it.

 

I said no $hit-talking. See you Monday.

 

And let the truth be told!!!!!

Anyways I am blessed with 4 young boys(yes all mine) this weekend so i dont know if ill be able to get anything done. i might if i can be a insomniac which i pretty much am as you can tell when i post. But i went to radio shack and got myself a new soldering gun.

http://www.radioshack.com/product/in...entPage=search

The clip that came with it is actually pretty nice it has quite the grip when i use it. so im sure it will be useful

 

dont forget, you can buy JUST the tips too. they screw right in.

I'll be following this thread!

 

no i know. i dont think i will need other ones but who knows it might help me out. i dont have real steady hands. Ive smoked for 10years so my hands are kinda shaky not to the point where it would prevent me from soldering but it is still affecting my soldering. Its funny cause i am real big into electronics. i have been since i was a young child. i was ripping apart my old 386 computer back when i was like 10 or 11. but i just never got into soldering that much. now i wish i would have

 

I hear ya, well that's unfortunate. Those little tiny connectors on the back of the ecu connector look sketchy to me. I get real paranoid about wires coming loose or touching in a little area like that. I'm curious to see pics of after you've connected the wires to that part.

 

There is nothing "sketchy" about it.

That ecu header connector is the same one that patch harness manufacturers like Autosport use.

Here are a couple that I am working on as part of a current project.
The one on the left is a Z33 and the other is an A33.

 

wow that looks really clean. i was just going to cake on that liquid tape stuff after i soldered it all up but i think i will be getting some srink wrap

 

pretty cool it just didnt look like there was alot to solder onto there.

 

you talking about mine or engs's?

 

I toatally snapped off the pin off the back side of the ecu to where it was flush with the plastic part that is why i had to push the pin back out. I just was to damn impaitent about it so when i couldnt get to the bottom pins i just started rocking away(dont ask)

well i did about a hours worth of soldering tonight using the method you discribed to me and it seem to be much easier that way i almost have half of the ecu done. hopefully if im not toatally worn out by tommorrow night i will finish.

 

I am very interested to hear your thoughts on switching from a Mass Air Flow setup to Speed Density

 

yeah i was talking about the back of the pins i the pictures you showed me. it looks like at most you'd get a 1/8" overlap of the wire onto the pin.
