 1UZ: who can wire up stock ECUs
|
Mon, 12 May 2003 03:21

okay, i am getting to the stage of wiring the 1UZ up.
we know NOTHING about wiring so am prob gonna get someone to do it so they can make neat fuse/relay boxes and stuff...that's the main thing i want done.
(some of these questions may sound stupid but i've NEVER done anything like this before..  )
1. if i were to get the loom made, would they do the wiring for all the lights and guages as well?? and if so do i need to get all the lights and gauges put in before i get the loom made up??
2. who can change/make the loom to run the standard two ECUs (it is a Crown 1uz using stock gearbox)?? i've rang up a few places and they say they can't do it...it is too complicated and they say go aftermarket.
3. how much will it cost me roughly to a) get my loom altered and made neat. or b) get a new loom made up.
i don't wanna go aftermarket coz that will like add another $3000 to the project and i can't afford that atm! 
btw - here's a list of stuff i am NOT using as it's a waste of weight! 
* traction control
* ABS
* cruise control
* A/C
* power steering
the car will only have what's needed! 
so yeah, i need to know the answers to Qs 1 and 2 mainly.
thnx!

Check the latest zoom magazine(has a 360kW supra on the front cover) there's a reference in there to a company in Qland(i think) that is doing looms for the standard ECU's.

will check it out.
i should also add that i am in Melb, so preferably some1 in the eastern suburbs of Melb would be best.
and yes, the fuses/relays must be done neatly.
the car isn't a top show car but it does go in some car shows (this isn't to say it's a full show car, i will drive it heaps).
but it does have to look nice, i have this thing about clean engine bays!

We do alot of this sort of work and to wire up an to wire it up by spicing the existing harness into your new engine harness and removing all the unrequired bits in a neat and professional job would cost you anywhere from $1500 - $3000 There is alot of hours involed to do it neatly and look good.

hmmm...sideshow i MIGHT be interested.
although i don't see how it'd work out cheap as you'd need to pay to get down here and back and of course i'd have to cover that  ..??
i was hoping that to alter the loom to run the stock ECUs would be cheap, but it isn't looking so.
i really am considering going aftermarket now...had a few places recommend the Wolf 3D version 4 for $1400 for that plus the wiring/tune cost.
if it costs just as much to alter the loom to fit the stock ECUs than it would to get a whole new loom made for an aftermarket ECU i will prob go aftermarket as it ain't worth paying the same money..
the only thing...one place has said that i'd need 8 new injector plugs and 2 new igniters...
do i need new ones, OR can the Wolf run off the standard ones and he is just bullsh*ting??

well i can do the job cheaper than the place in qld and that includes my trip down there
but if u want to go aftermarket ecu im not to sure if the std ignitors work
i know theres a lexus v8 with a haltech gettin built so i could find info on that or u could ring haltech for info
but an aftermarket ignitor (bosch) costs about 250 bucks so u need 2 of them
best bet is to ring some ecu makers
wolf ems haltech
and see what u need to hook it up to the v8
no use buyin the ecu then findin u need all this extra stuff to get it runnin
just ring afew places and see how u go
good luck with it

How can you afford to charge less than $1500(that was my bottom end figure)?? After airfairs, parts, accomodation cost, etc, there won't be much left in it for you.
Just curious do you quote jobs or go by hourly rate? If hourly what is your hourly charge?

I'm running Delco on mine. Like Sideshow says, you've gotta add up all the extras.
I'm running the standard injectors/leads/coils/injector plugs. Different ignition modules though ($200 each).

For that kind of money, you should be tempted to at least TRY yourself. So long as you haven't hacked the original loom to pieces, there's only actually a few wires that need to be connected, provided you use good quality fittings, tape, loom tube etc., it shouldn't be too hard to get a fairly decent looking job - or are you trying to go completely hidden wiring? That's a pain But there's still no real need to buy an aftermarket ECU - the worst you'd have to do is hack up the original wiring totally, and start again. So long as you have all the engine parts and both ECU's, there's nothing too hard about it...

Cost me $150 for computer & wiring harness & ALL sensors! But that blew out to $3,500 for the computer with wiring/tuning. And thats still not the best wiring!
The wiring I could clean up myself though. Actually if I've got some time tonight I might have a look.

yeah i'm thinking that Mr.Shin.
most places have said that they'd want to make up a new one...now this looks like it's gonna cost $1000 minimum.
so i'm thinking if they're gonna just make a new one anyway, then i'm definately gonna have a shot with the old one myself!! coz if i stuff up the loom then whichever place i chose won't need it anyway!
and for a $1000, i'd be happy if it took me a month of weekends to do it myself!!

That's it, you can't hurry these things Main thing is to think (and draw) through everything before you do it, so you can get all the wires you need going to the right place in one shot, so it's tidy. Wiring is like turbo manifolds - if you pay someone to do it you're looking at $1000+, if you do it yourself you're looking at, say, $100+time+burnt fingers

i have over 6 to 7 yrs experience in toyotas
i have done many 4a series enignes and after awhile u get to know the wires
1uz are same
theres nothin to complicated bout them i think
ive never done one but i cant be harder than a late model 1jzte
which i did in a cressida
i usually knock a car of in a day if all goes right and if the engine is goin into an easy car like an old car its piss easy to hook up relays n stuff
hard part is the automatic so im not to sure there but if the
wiring of the front cut is there then hteres not too much probs
i make my own diagrams when i do a new job if i have time
so newxt time its easier
like today i did a 1jzgte in an early 2 door soarer which originally had a 7m in 7 hrs and that included hookin up the power/economy switch and overdrive tooo
airfare is only 200 bucks
i read the article in zoom about 1500 to wire up a 1uz
i cant justify that price but i have not done one b4 so i dont know how long it would take me but if it takes me longer then my loss
im not tryin to rip people off
a usually day of 7 hrs work at a mechanics at say 70 bucks an hr if yr car was gettin worked on is about 500 bucks
so how long does it take u to do the wiring
if someone sent me a loom i could do it in my spare time so i wouldnt loose much
but when i go onsite to the job i like to finish the job in a day
but anyway im not here to compete against other people
im tryin to start my own business and tell people what i can do
only way to learn is to do more jobs

fastj,
If you can follow a wiring diagram and solder two wires together you can do it yourself.
Which engine/ECUs do you have? I will probably have the correct wiring diagrams.
Is it Soarer, Celsior, Crown, Crown Royal Saloon or Crown Majectic? They are all different so you need to know which one you have.

biased99,
Thanks for the backup.
fastj,
like I wrote, if you know how to solder two wires together, and can follow a wiring diagram (not very difficult) you can do it yourself. I have the wiring (which I made myself due to only having crap japanese diagrams that were unreadable) for Crown ECUs and can probably answer all of your questions. You will have no problems getting all the ancillary equipment that sideshow mentioned running (eg neutral start switch, reverse lights, alternator, AC, temp, oil). Toyotas are pretty much all the same so you can get this wiring from other diagrams.
Usually I recommend that people remove the temp sensors for their instruments from the original engine and plum them into the 1uzfe somehow (mechanics is always easier than electronics) so that your instruments will still read OK. You don't have this problem because you are starting from the ground up and I guess will use aftermarket guages. I have a Ford Fairlane with a digital dash so this wasn't really a valid (or prefered) option for me.
When I first did the car I had it running on the stock Crown ECUs but I moved to aftermarket so that I could accommodate changes later on and so I could use my tiptronic gear changer controller.

believe me, i WILL research this HEAPS before i actually do it.
starting to really look into now, getting some good options/help finally.
as for doing it myself, the thing is i don't quite understand fuses and relays just yet...
like there is the one big group of them in the engine compartment and then the OTHER big group of them inside the car!
the current loom loops around in a full circle (although i think this is only for lights and stuff but am not 100% sure) so that makes it hard.
see this site...scroll to the last pic to see what it looks like at the moment...you can see the engine fuse/relay box and also the bunch at the top middle (sort of) of the cabin fuses/relays.
http://home.iprimus.com.au/aaron83/emhc/clubcars/A aron/Aaron_01.htm
concerning gauges...i will most probably use aftermarket...not 100% yet. might use oringal gauges and then just get a monster tacho...gotta see what will suit it best..
