to be honest every product needs a gimmic to market (the autotune is no gimmic) and with the vipec they have chosen to that particular feature to speruke.

fair enough. i would have a vipec board in the GTR now but the tune last thursday didn't go ahead because boards weren't available.

so the QT doesn't really save much time at all?

the demand for V44 Skyline plug-in boards has been overwhelming...so much so that the manufacturer has been unable to keep up. More should come available very soon.

Scooby if tuning was based on the time it took then Haltech ecu's would cost $2000 to tune...lol

lol, yeah i see your point.

if a tuner tuned a car according to QT only then chances are the car will blow up. There is more to tuning then just doing the cruise fuel maps

you have to realise that there is alot more to a tune then just fuel ratio's.... if a noob plugs in a vipec and loads up auto tune and tunes the car it probly wont work, the guy from UE said to me, the tuning part on the dyno is the easiest part, its only 20% of the tune, the rest of the tune is setup.

If the tuner gets the setup wrong then your screwed

i do realise that there is a lot of work in proper set up tuning, and expected QT to be an adjunct only, but the Vipec literature is bold and unambiguous. maybe it needs to be changed slightly so expectations aren't raised. my question was just cost vs benefit ie if it's really such a great time-saving measure why Vipec does tuning still cost the same. i understand from what you guys are saying that QT is good, but probably doesn't save that much time, so it makes sense that it's not going to change the cost of tuning all that much.

thanks for clarifying

Yep I agree with the Haltechs - at least the early ones .

I was never comfortable with how they had the software - gauge pressure instead of absolute and their innitial resistance to sequential injection . The early ones possibly were short on processing power and the loom sockets limited in pins and wires .

I don't know if they stayed with the bar graph interface but that was hard to stomach too .

I played with an E6 an F9 and them an Autronic SMC which software interface wise was much much better - once I learnt to set the charge temp estimation table properly .

The major limitations I found to be manifold pressure sensing because setting air temp corrections was so critical and if it's wrong the tune can be a bit eratic .

The only people that ever convinced me that MAP could be ok were the fellas at Allen Engineering (Malalla in those days) but they parked a MAF sensor in front of the engines air intake when they tuned their Autronics and logged everything .

That way they knew how much air was going in and its density in one simple 0-5v signal .

So for me EMSs have to be able to run from mass air sensors which at the moment means a Power FC .

Truth be know the best Skyline computer could be the standard one with something better than flash memory so it could be tuned in real time and saved like in a PFC or other aftermarket computer .

The ViPec does look very interesting and I hope in future ways can be found to make knock sensing systems fast and accurate enough to prevent engine damage .

Need the mass air software , cheers A .

the new firmware update has AFM options for you mass air lovers...was up on the site but has been taken down temporarily.

Nistune does that. However, by the time you buy Z32s or similar, and a boost controller, you're at the price of a Vipec board anyway.

STOP PRESS: we are currently looking into developing a simple dash style interface similar to the Power FC Commander unit. Should satisfy all the boy racers out there...will have all engine parameters (hopefully including knock level) complete with warning lights and shift lights.

Stay tuned!!

call me a boy racer then.... i still like to be able to keep an eye on the knock water temp etc... its a handy lil thing

I think the Boy Racer statement is crap.

My power FC hand controller has saved my engine from overheating to the point of destroying itself at least 4 times or so that i can remember.

The coolant temp sensor on the dash only moves to the H when the temp gets to 110deg, it does not even work if the water leaks out of the car, so it only works when there is coolant / water in the system.

So yeah the ECU temp sensor is a better sensor and it still works when the coolant leaks out of the system, so yeah when my power fc temp was reading 99deg (last time i caught it the thing got that hot) my dash gauge did not move from running temp.

Pulled over worked out the issue, got the car home filling it up every 4 minutes of driving and replaced the radiator and its still going strong, if you have spent 6k on a forged motor then being carefull about engine temps are a must. imo

Hey dont get all upset ya thin skinned fu(kers...im a boy racer too :down:

the only thing i used to display was coolant temp....displaying knock was something that never worried me as my car was well tuned and i used sealed drum fuel when racing and any dangerous knock is shown by the 'check engine' light.

i think for the price of the hand controller a peak hold temp gauge would have been better as my h/c was more used during tuning than anything else.

Anthony you must admit a lot of guys want the hand controller fixed to their dash to impress people...and wouldn't have a clue how to properly use it (ive come across plenty of these guys)

Hand controllers get the chicks hey ??

Hey guys,

what are these vipec ecu's like compared to something like fcon pro? put the limitations aside with the fcon's "access to tuning software problem" and tell me what you think!

tho i guess this question would be hard to answer since not many people have looked at the fcon from a tuning point of view but surely someone would know :down:

Cheers.

???????????????? no body?

ohhhh yeah mate.. the chicks were like, omg show me your knock readings honey

thats some funny sh1t ^

good thing it doesn't display egt's...they would have been high!

    • Actually, that's not entirely true. It's also the same motor in the 1st gen Nissan Cube but they're rare as hen's teeth.  
    • Yeah it is always worth testing and balancing actuators out of the box, just set the pressure regulator on a compressor very low (eg 5 psi) and increase it slowly to see when they both move.....unfortunately while you may be able to adjust the length of the actuator rod to minimise any difference, the actual pressure they move from is not adjustable so you need a well matched pair. And yes, the VCAM is probably contributing; the earlier in the rev range they come on boost and the slower the revs build (I think your demo was in 5th), the more you notice it.  Driving at WOT through 1st, 2nd, 3rd etc you will probably never hear it as any shuffling starts and is over super quickly
    • oh they were with that motor, you need to remove the engine to change the spark plugs (don't have to, but it does make it easier)
    • I certainly fall into the annoyed camp, but glad to hear that if it's happening at low boost then I'm not likely going to blow a turbo and end up with metal shards in my oil. Just feels like it prevents me from really driving it without hesitation and "peak" performance. Wonder if it's the VCAM, it did an impressive job of shifting the torque curve and faster spool, but maybe now it's "too fast" and there's too much air for how open the throttle is.  Based on some other threads, will also do some reading on synchronizing the actuators. They are the default actuators that come on the Garrett's and I would think they would be set the same coming from the factory, but if the turbos don't actually work exactly the same way at the same time as previously mentioned, it would be worth making sure the actuators are actuating together properly
    • I went down this rabbit hole before, ended up sourcing a motor from the UK (I'm in Japan) which also didn't function correctly. With the original motor, I disassembled it and reassembled it and it works somewhat, sometimes. What I could deduce from all my screwing around is that there is calibration of the gears on the inside of the motor and two ramps on the main gear which activate switches that operate the motor and move the sunroof either to retract into the roof or tilt. Where I got stuck was that, it seemed in my case that one or both of the switches that are activated by the ramp on the gear did not always activate and thus the motor did not move, causing it to sometimes not retract or tilt (apologies, I've forgotten which way it didn't work.).  Of course this part is discontinued at Nissan now, it's the same part in the S15 but no other models. I also contacted the manufacturer of the component for schematics - forgot the name, they're based in Gifu - but they declined to share the information due to being bound by an NDA, sadly. Looking through my pictures now, it seems I last had a crack at this in 2022. See, I so kindly wrote "open" and "close" next to the switches. If you figure it out, please do tell me. Those little switches, with the red buttons may need to be replaced.
