Hello, is there any device, program or tools that can datalog 350z? especially knock count/sum...
any input would be appreciated. thanks.

1) UTI,
2) MPS,
3) UCC,
4) Cipher,
5) Consult II,
6) Utec data dump.

 

wow...thanks for the post.
i will start search from the top of the list.

sorry for the newbie questions about z's.
own evo and new to 350z...
thanks.

 

just a quick question.

anything on the list that does not need some sort of piggyback/standalone unit connected to the car?

for ex, on evo, all you need it OBDII cable(tatrix cable) with logger program(ranges from free to 20bucks...) to datalog.

will appreciate all you inputs.

 

Cipher can't detect knock, fyi. But it's still great

 

Comment on Red and the rest I'm not sure.

 

UCC also needs UTEC...

Cipher and Consult II read the factory ECU.

 

so cipher does not log knock, it comes down to consultII.
other programs looks great but requires UTEC...darn it...

do you guys know if FCON IS has any datalogging capabilities? i know it displays but when you are in WOT, you can't look timing, af and knock at the same time.

 

Not a cheap solution if you are only looking for knock logging, but Haltech Platinum has advanced knock pickup and has no problem data logging it along with the other engine functions. It can be triggered at WOT, upon a set boost level, rpm, etc.

 

why pay more if you can use Utec and have a laptop attached to do some logging. MPS and UTI cost only $20-$30 anyways if you want a GUI interface.

 

well, planning to get FCON IS for engine management for APS single turbo kit.

so, haltech has "Dual Closed Loop 02 Control", what does that mean?

there is alot of limitation with 350z engie management since i live oversea and there aren't many tuners here. I am kinda familiar with evo tunning with ECUFlash and good datalogger(like EvoScan which can datalog almost everything from 2byte vs calculated ECU load to knocksums).

so, haltech is complete stand alone, correct? so that means you have tune from begining with cold start, idle, different elevations/temps etc.

does closed loop o2 control make these tunnings easier??

 

It means it can use AFR feedback to target a certain value at various loads.

Haltech still uses stock ECU for drive by wire (throttle) control. So idle is still controlled by stock ECU - need reflash to adjust that, still. Cold start, temp compensation, etc is all controllable via Haltech.

Closed loop does make tuning easier because it "learns" (tweaks) on its own to find the right target.

 

1)so Haltech is NOT like AEM EMS unit where stock ECU is replaced by their own unit, correct? does that mean you still get to keep stock ECU's safety features?

2)what's the load like when you go with single turbo kit in 350z, trying to boost about 8lbs. does stock ECU have enough load column for this amount of power? I had to rescale my ECU load column in lancer evo way above when i went with meth injection(19 lbs stock boost to 29lbs meth/water boost). which brings another question...is piggyback system, like FCON IS good enough in this situation? since i don't have any datalog of 350z stock vs single turbo, i can't quote anything but, what if you hit way above your highest ECU load colum with single turbo? what does piggyback gonna do???

thanks all for the input...

 

I'm not familiar with Haltech but standalone EMS has its own map for Fuel, Ignition so it won't be using the ECU. I have a Utec and on boost/load Utec act as a Standalone and takes control of the FUEL and Ignition using its own Table. Hope this help.

 

The Haltech Platinum is a pnp standalone fuel, ignition and cam timing controller. The factory ecu is left in place just like you say to keep some factory functions such as safety, dbw, traction, gauges, etc.

The factory ecu meters air from the MAF, not load (in psi). Once this is maxed out, you need a MAP sensor in the system. The Haltech comes with a built in map sensor that reads up to 22psi of boost, or you can use an external map sensor up to 60psi.

 

hmm...very interesting. so, haltech still keeps ECU..
1)may i then ask what's the difference between UTEC(used to be famous about 2 yrs ago in lancer evo's) and haltech?

2)if stock 350z ECU reads MAF frequencies, then when and how do you know you actually 'max out'? at least in evo's, ECU load is not direct relation to the boost but somewhat very related. actual calcuations involve injection pulse width(IPW), AFMAP, and battery voltage and bunch of numbers.
so when you 'max out', you use MAP(manifold absolute pressure) sensor but i though most(at least GM map or AEM or zeitronix) map sensor has 3 wires(power, ground and 0-5v output) and how can you tune the car with MAP sensor???
3)then i assume you can get rid of MAF once you start using MAP sensor, correct?

sorry for so many questions...i will search again about haltech...

appreciate for the replies...

 

do a search on the utec - many threads on it. UTEC is standalone but only at load. It also has limited load points (like 12). Haltech has 32 and is standalone ALL the time.

do a search on the uprev Osiris solution to understand why the MAF is maxed out. The UTEC manual I think also points this out. You can download that from the turboxs website.

 

The MAF operates on voltage, so it is easy to tell when it maxes it out (which is not that high of hp, I don't remember off hand though).

With the Haltech you can delete the MAF from the car entirely, and it has complete control of fuel, ignition, and cam timing at all times through maps up to 32x32 resolution each. The UTEC shares fuel and ignition with the stock ecu, and has (from memory) 10 load points. Also, UTEC has no control of cam timing. The UTEC can be tuned to make WOT power, but to get the car to drive like stock (transitioning in/out of boost) is more difficult. Not to mention the user interface differences... Haltech uses USB connectivity with new windows software, compared to having to telnet into a dos-based utec.

If you have any more questions feel free to give me a ring Monday at 888-465-7373 and I would be happy to answer them.

 

You cant compare Haltech, Motec, Vpro to Utec since Utec is not a full stand alone and it cost much less!!! Utec is a piggy back when not on load and it runs on the ECU (I think it still uses your UTEC Column 0 for fueling but not Ignition). Utec only takes full control of Timing and Fuel on load/boost. InjectedPerf is right about the drivability of utec going in/out of boost, and it can really be frustrating after awhile.
