Utec

[N16_VQ_SWAP]

hello

which wiring /terminals are important to install the Utec into a 5.5 maxima?

thanks

[Puppetmaster]

IIRC, it'll just be similar to the Emanage Ultimate... basic ones would be:

Injector signal (for all cylinders)
Ignition signal (for all cylinders)
MAF
TPS
Knock
Power (probably ECM power)
Ground (probably ECM ground)

I'm sure there are more.... I'll see if I can find a good thread.

And because the UTEC is set up for a 350Z/G35 type ECM harness, you'll need to do some remapping using the Z33 wiring diagrams.

PM SurraTT, I know he's worked on this before.

[Puppetmaster]

Okay, here you go:

UTEC is in..........

[N16_VQ_SWAP]

yes i read this post but what is with cam senor 1 +2 ?

Intake Temperatur? and the rest?

i have pm'd supra tt.. but he is not online......

thats my wiring




but not go

Is all correct ??? anything forget?

[N16_VQ_SWAP]

hello???

[SurraTT]

dude its a lot more complicated than that.


if u have a 02 max ECU u have to compare the max pinout to the 350 pinout and figure out what is what. obviously the wires arent in the same order/layout........


one of those measure twice and cut once deals here...



so do you have anything hooked up, or what are you doing??

is ALL you need is what wires to hook up?? if so then its just the basic tunning stuff,

ECU Pinout cheat-sheets (large images, 1000+px wide)

[SurraTT]

ok so i looked at the pic, and i see u put the max connector on the utec..



soo now ur trying to put the 350 plug on the engine harness????

if so. then it does not matter what wires the utec uses if all are going to it ne way


sooo umm did u hook the right utec wires into the max plug??????

[N16_VQ_SWAP]

noo the pic is old. i cut all.

and now i need only the the right pins to connect the utec. NOT fully plug and play! I need only the once wires.....

is the list correct?

which pins are important for the Utec?

[N16_VQ_SWAP]

hello

i have connect all important pins but whats with the pin 34 ? RPM.. need the Utec this?

thanks

The Z33 DE doesn't have an RPM output at the ECU, the UTEC uses other means to determine RPM.

[N16_VQ_SWAP]

Ok... but why dont start my car with the Utec? without runs good.....

Well have you checked why it's not starting? Fuel, spark?

What map are you on?

[N16_VQ_SWAP]

hello

i have connect all cable new, complete new wiring and i think its all correct connect....

spark, injectors Walbro pump runs before and not with the utec now....

I have install the 2.8 software on the Utec... map? i switch it on position 0, the utec use the original specification from max ecu or?

I dont can connect the utec with my laptop... i have windows vista installed and dont works... Windows vista dont have hyper terminal... which program can i use for perfect work/connection under windows vista?

do you have the utec in your car?

I ahve a 02 max engine with following mods:

- 350z complete intake manifold
- 350z injectors
- 350z thermostat
- iridium sparks
- 350z fidanza flywheel
- exedy stage 1 clutch


thanks for your help

[pmohr]

So no spark and no fuel now?

Have you triple checked all of your connections, and pinouts?

Just found out that with Vista, you have to make hyperterminal active. You might have to go into the control panel or windows settings and turn that feature on. I didn't think that it had it either, but my roommate found it. Probably want to google search that one.

[tonedef]

just by a cheap lap top with xp, or 98.......

[N16_VQ_SWAP]

no no fuel is going... spark i dont no.....

into the utec software download is hyper terminal 6.3 but i dont come into the utec main menu.. i think its dont connect to the utec.....

when i switch the utec of MAP 0, used the utec the original max configuration?

i have patched the new version ( 2.8) on the utec.... so the old maps of the utec its delete or??

S H I T utec i hate it now.... i will start my engine....

its run without utec! here is a movie from it....

Sounds like your pinouts are wrong. Remember you need to get a wiring diagram of the 350z ECU and one of the maxima and match up the pinouts. The way I did this was to make a chart with the things I needed IE what puppetmaster listed:

"Injector signal (for all cylinders)
Ignition signal (for all cylinders)
MAF
TPS
Knock
Power (probably ECM power)
Ground (probably ECM ground)"

then put a column for 350z pins and another for maxima pins, then write down which ones go to each. From there you can isolate the 350z pins/wires that are on the UTEC and connect those to the correct wires on the maxima harness/ECU.

[N16_VQ_SWAP]

i use this page for the correct connection

ECU Pinout cheat-sheets (large images, 1000+px wide)

i drive tomorrow to my garage and make pics for you..... iam sure my wiring is correct...

The 350z and max have the same cranks sensor?

its windows not combatible with the utec? i install hyper terminal 6.3 ( its into the 2.8d software package) put i dont open me the utec menu.....

i dont have a old pc or laptop with windows xp /98se......

and a other program for the utec?

when i connect the utec with the hyper terminal then i have a whit screen into the window....

[N16_VQ_SWAP]

i have a new pic



But the engine dont start ....... wiring its all checked and OK

whats wrong?

My OBD Tool tell me mistake 335 Crank posi sensor.... i have installed the 02max sensor... must i need the 350z now???

You mean P0335?

The Z33/A33B CKPS' are identical.

More than likely you damaged the CKPS wire, or tapped into it incorrectly.

[SurraTT]

if your getting crank pos sensor code. then check that pin, and the wire..



and my 02 max actually ran with out a crank pos one time. so idk if utec will allow that. but some how my car did. it just took 20 seconds or so of cranking.

Yep, they'll run just fine without a CKPS on there, but IME it'll take forever to start up (reverting to getting timing info from the CPS', my best guess), you'll have no tach, and it'll be down on a bit of power (disables CVTC and reduces engine power on purpose, I believe).

[N16_VQ_SWAP]

without ckps runs the engine? why my not? ok i check the wiring

again, but i think the wiring must be ok.......

S H I T VQ swap .....

hey SurraTT please come to my to germany and help me ;-)

i think the 350Z becomes the tach over canbus.....

[N16_VQ_SWAP]

hello

please look at my picture from utec... the TPS is at 72% is that OK ?? The engine is NOT running!!!

Its to high, or???

I have check the POWER and Mass from ign coil, injectors, Crank pos, cam posi MAF... its all ok.....

Have one of the Utec user here a pic from his utec? ( engine dont run! )

edit:

I have found a pic at the 2.8d download file




and here is my file



PLEASE LOOK AT TPS

[N16_VQ_SWAP]

hello

i have deinstall the Utec... now runs only my maxima ECU and the engine runs good....

So what is the problem??? Whats wrong?

thats all connected:

Injector signal (for all cylinders)
Ignition signal (for all cylinders)
MAF
TPS
Knock
Power (probably ECM power)
Ground (probably ECM ground)

But TPS, all TPS wiring or only TPS 1 signal ??

And MAF only signal or all from MAF ???

Is one guy here, it have
successfully run into max???

[SurraTT]

so whats the problem????



when the utec is in the motor dont run. ok


does it crank???

getting Fuel?

spark?




there is no "hook this up" and it will work just fine answer......

[N16_VQ_SWAP]

hello

yes when the UTEC is out, the engine runs..... Utec is in engine not run.....

Fuel OK

CKPOS is brocken,but the engine runs without Utec

spark all 6 signal connected

Can you tell me which pins exactly for the right connection?

SPARK:

Pin: 62 , 61 , 60 , 81 , 80 , 79


INJECTOR:

Pin: 23 , 22 , 21 , 42 , 41 , 40


KNOCK SENSOR:

Pin: 15


CKPOS:

Pin: 13


MAF:

Pin: 51

No Intake temp, ground or power?


TPS:

Pin: 50

Only TPS 1? whats are with TPS2, throttle actuator, throttle relay?


Ground:

Pin: 1 , 115 , 116


Power:

Pin: 109 , 119 , 120 , 121

And whats are with the rest?

IVT , cam posi 1 + 2 ?

Have you successfully connect the Utec into max and runs the car?

here a movie w/o Utec and the engine run

http://www.youtube.com/watch?v=bYOFBuVikcU

[SurraTT]

if you are hooking those wires up, it should def run

[N16_VQ_SWAP]

hmm... but it dont start.

I have download the base map and parameters from TurboXS
And install the 2.8d version....

must i modify any settings into the base map or is the base map so ok?

[Deckdout2]

Can you provide a picture or 2 of what exactly you have going on there? With the wires spliced from the UTEC and 1 of where it's actually connected to the ECU.

that dont matter, if the utec is on 0 which is stock ECU,

if the car dont start/run on map 0 then its a wiring problem

hello

i have the Utec new installed but the engine dont start with the utec.

PLEASE PLEASE help me!

Here are pics from all

[N16_VQ_SWAP]

more pics











whats the mistake?

[pmohr]

So again, why won't it start? Fuel? Spark? Have you checked anything?
