Mike
nadam se da se neces naljutiti ukoliko se upletem i odgovorim na ovih par misljenja koja si dao. Ovo je obicno iskrivljavanje istine. (resnice)
Frekvencije knocka nisu odabrane slucajno niti palac-oko metodom. To su najcesce frekvencije koje koriste knock senzori koji imaju flat response, kao npr Bosch ili Delphi. Tu je i LP na niske frekvencije. Da se ne bi tu natjecali cija mama bolje kuha, nema tog motora koji se ne moze pinpointati u bilo kojem svojem rezimu i bez obzira na tvoje misljenje, filtrirati knock i vise nego uspjesno. Vipec nije elektronika iz perine šupe, vec visokoprofesionalni komad opreme, sto svatko tko zna citati izedju redova,, moze lako vidjeti izmeðu tvojih rijeci. Naime, ne bi se ti toliko trudio, da se nisi i sam zapitao i zabrinuo
To da je sistem precej i out of date, mozes samo sanjati. TI ces morati dokazati ono sto TI ovdje govoris, a to je totalna neistina. V88 itekako savrseno odraðuje posao, i samim time se SKN Slo ne boji dati GARANCIJU na motor. Da li je tako s tobom, ne znam, i niti me ne zanima.
MikeLima je napisal/-a:Lambda... Ne morem se nic rect, ker ne uspem najti ne nastavitev, ne tabel ne nic razen nekaj vnaprejsnih nastavitev in precej siromasno nastavljiv closed loop. Se bom se potrudil... Mislim da vec kot dveh senzorjev ne uspe podpret ne tako ne drugace.
Ne znam kaj ti tu smeta, ali cinjenica je da za razliku od Moteca, koji je siromasan ulazima i izlazima, V88ima dovoljno ulaza da koristi i 9 lambda sondi na svojim analognim ulazima od 0-5V. Pogledaj i sam i dokazi da sam u krivu.
Sto se tice closed loopa....radi savrseno. Morat ces dokazati da je LOS, kao sto kazes, ili siromasan. Mozda nema neke fancy stvarcice, ali mu niti ne trebaju. Drzi lambda=1 ili AFR 14.7:1 kako god zelis i u bilo kojim uvjetima, pa prema tome, NEMA MINUSA. Simple as that. Radi. Simple as that. Bio bogat ili siromasan..
MikeLima je napisal/-a:Se mi prav zdi, da je stevilo tabel omejeno na 12? Da je kalibracijskih tabel samo 6?
Tabele za gorivo in vzig so malo majcene (22x20), za kak bolj zahteven motor.
Nikjer nicesar o CAN-busu, ali pa ne znam najti.
Broj tablica nije omejeno na 12. Dapaèe, ima ih 18. I to 18 GP On/Off i 18 PWM. Mislim da je to i vise nego dosta.
Tabele za gorivo i vzig? Mislim da tu kucas na kriva vrata. Pretvaras ovo u feature war, a ovo je predstavljanje elektronike. Serijski ECU ima 8*8 pa radi savrseno i vozi aute 20 godina bez kvara. Nema tog motora koji se sa 8x10 tablicom ne moze savrseno napraviti. A kamoli sa 22x20?!
:D:D Krivi ti je argument, jer svi znamo da ne treba staviti breakpointe svaki okretaj, vec je dovoljno i svakih 500. A i 1000 u puno slucajeva. Pogledaj si ovaj filmic, koji je napravio Ben Strader na Autronicu (a Vipec je barem 10puta sofisticiraniji), pa onda pricaj marketinske price da je 22x20 premalo?!
http://www.youtube.com/watch?v=vZQvB0KD5NA
Pametnome dosta, a smatram da si ti upravo medju njima.
Sto se tice CAN protokola, koristi se upravo Motecov protokol. To je implementirano odavno i V88 i V44 bez problema koriste Motecov ADL i ostale djidje..
MikeLima je napisal/-a:Na splosno je vtis da se trudijo. Vsec mi je, da ima 4M spomina. Sicer ne vem koliko cesa gre v ta spomin, koliko je kompresiran zapis. Sampling je max 50Hz. No, vsaj 100Hz bi bilo fino.
Do 10.12.2009 (PRI SHow Orlando, Florida) Vipec bi trebao imati sampling od 500Hz. Trenutacno je na 50Hz, jer se radi kompletno novi 64bitni software, koji ce imati jako puno novih stvari. S obzirom da su svi zauzeti na tom poslu, jer se 10.12. opasno blizi, za ocekivati je da ce se neki featuri pojaviti iza nove godine..
MikeLima je napisal/-a: Ce smem primerjati, bi rekel da je V88 tam nekje kot Motecov M48 ceprav ta ze zmore furat dva injektorja sekvencno na valj in se kaj. Sem pricakoval podobno ceno, pa mislim, da je ViPEC malo drazji. Ampak z M800 ga pa ne gre tlacit skupaj.
Ako ja smijem primjetiti, V88 je jaci i i sposobniji od Moteca M880. Pogotovo za cijenu koju nudi.
Evo jedne tablice koju sam napravio, a podaci su izvuceni iskljucivo sa stranica proizvoðaèa, da ne bi bilo zabune.
To moze svatko provjeriti na http://www.motec.com.au/aboutecu/ecucomparison/
Tako da usporedjivati V88 sa bilo cim OSIM M880 je smijesno.
Dapace, i to je vise nego smijesno, jer molim te da javno napises cijenu moteca M880, sa SVIM DODATNIM UKLJUCENIM OPCIJAMA koje ima V88.
Znaci , da ne bi bilo zabune, molim te cijenu M880 sa sljedecim opcijama ukljucenim:
Lambda wideband kontroler (da radi dulje od 6 sati koliko radi bez OPTIONS doplate), sa 8 lambda sondi
Logging (da radi sa 4Mb i da radi isto kao lambda)
DBW potpuno funkcionalan
Anti Lag, Launch Control i Traction Control potpuno funkcionalni
Da rade sve 4 odmiène
Da radi sekvencijalno 8 tuljava (a ne 6, kao na M880 BEZ OPTIONS)
Da ima 10 digitalnih ulaza
Da ima 10 analognih ulaza
Da ima 10 auxilary izlaza.
Hvala i citamo se.
I BTW, ako se pitas tko sam ja, ja sam onaj koji je Cicerov Seat Leon i Beetle od Zdenka Robide popravljao nakon RSR-a (nakon sto je eksplodirao motor od R32 u beetlu i nakon sto Leon nije mogao raditi kako treba). Ti auti voze i dan danas.
Mozes pogledati o ovdje, ja imam stranke koje nije strah niti sramota staviti svoje aute na net.
Pogledaj i sam:

I onaj tvoj evo nema 700ks ma koliko ti trubis o tome. To je Norris Design motor sa GT35 turbom, a taj turbo ne moze napuhati vise od PRAVIH 600ks!!!! Sa trkacim benzinom i samim cudom, taj motor moze dati 650-670ks, uz bozju pomoc.
Zato ne spominji 700+ks, jer bi bio prvi u svijetu

EVO 8 V88 SUCCESS
Postby APE » Wed Sep 09, 2009 11:40 am
Race car / Street car V88 EVO 8
Having tuned this or similarly modified same models, I cannot express just how impressive the result is with the Vipec. We have never enjoyed such success with factory ecu, Motec, power fc or other brands already known to you. The car has a stroker crank to 2.3L, HKS 272 cams, adjustable gears, 4 large injectors, high volume in tank pump with external 044 pump, large throttle body & other considerations that all make these cars a little cranky re start, idle and compensation for loads. To say it runs as refined as factory would be an insult to the way it functions. It starts equally well, IDLES BETTER with and without air conditioning and yes this IS WITH THE CAMS ETC. It drives superbly linear from idle and you simply cannot perceive where it leaves idle settings. Furthermore it will drive seamlessly in 1st gear from idle to 2k rpm at virtually no load such as would be done in carparks or road works. Range throttle up and down in these ranges and it simply and smoothly responds without shunting or hunting at all. Add air conditioning at idle and you HAVE TO watch the software to confirm it engages and disengages. Yes it is THAT GOOD. Now stand on it for the conservative 336kw atw and feel it rocket away on the track circuit sounding clean and solid in the process. Fuel economy not monitored yet but should be impressive looking at the stability of mixture control. Knock correction PER CYLINDER works superbly and is relatively easy to set up and tunes so this offers further peace of mind re changes in fuel or other things after the car is released to the client. Flick the switch and antilag is ready and waiting. Hold the clutch and stand on the throttle for launch control that simply works just like everything else Vipec controls. For those who have been doing these cars with similar modifications using other computers, SUCKS TO BE YOU. Our policy from now in such a vehicle is simply, no Vipec, no tune. Take it away or sell your substandard ecu so we can do the job to the best potential possible.

V88 tuning progress
Postby APE » Fri Jul 25, 2008 9:35 am
For those interested;
Mapping R33 GTR with V88 and TFE adaptor harness.
The install was relatively quick and simple with the TFE breakout harness.
Running through the menus and configuration for everything was a breeze.
Right click on anything and click on what's this? Takes you straight to the menu item relevant to the task. (We all knew this of course, just thought I would add it)
TEST MODES
Test the ignition, injection, idle control, air cond clutch, tacho etc without even starting the engine. Great way to confirm wiring integrity.
TRIGGERS
Setting up triggers was simple. Just click on the Nissan opt & RB26 and all sets up for you.
Then go monitor triggers whilst cranking the engine until trigger is learned. (Software views the large window cyl reference and counts to crank 360 deg trigger to show how many appeared during the large window opening)
Quick adjust of fuel master and it ran very well.
IDLE
This is simply brilliant. Set the desired idle speed, then run through the set up in open loop to calibrate duty cycle for the base idle and idle up modes for power steer, air conditioning etc. Also set up the start up step duty cycle.
Now set the min max clamp values and turn it to closed loop for perfect idle with or without any loads. Turn loads on AND off without flaring or hunting issues. Set load rpm same as base rpm and see if you can see the tacho change when you switch them on and off. It really is that good.
Start the car no throttle and watch the tacho stability post start. Seems they really have this sorted well.
I will offer update on dyno mapping throttle/manifold sometime next week.

Cold start and associated calibrations allowed brilliant control and stability (Really cold mornings here this week, down near zero)
Throttle manifold mapping.
Removed air intake hose from throttle body and mapped the entire fuel table from throttle position as a normally aspirated engine.
QUICK TUNE
Use of auto and manual modes did not take long to work out and the auto mode is really quick / really accurate. No complaints at all. Use the tune ahead or tune down for whatever you require at the time or just cell by cell as we do with the A brand. Use the manual version, which should be labeled "semi auto" Just manually accept the tune when the value aligns with target rather than letting the computer decide it has met the target.. Choice is yours but all work well.
Fitted intake hose and applied the 4d fuel table to offer manifold pressure correction to the throttle mapped table.
Made more power with less boost and mapping found an easy 266kw from factory 204kw.
This system is so seamless that it is just a joke.
Expect to spend a little time in the menus to get used to the different layout and requirement of ignition on but it is all worth the result. Fantastic repeatable stability of all functions.
Knock control
Monitor knock during mapping as you normally would with detonation head set but this also allows you to monitor logged knock levels and calibrate the table during tuning so the final result can offer ignition reduction if levels exceed your programmed values. Not just look at them or flash a light for you but actually correct them.
(Great bit of safety for those clients who muck with fuels or simply different atmospheres where you may not have perfect correction values programmed?)
Will let you know more when we do other things with this car but so far exceptionally impressed with the product and looking forward to the next one.

No stress Ray
Final results of this vehicle are so refined it is clearly the best result we have achieved on any GTR.
For those who have used other ecu models, you really need to try this to see just how suited it is.
Power is easy on most computers and this is no exception but the exception is the repeatability, the stability and refinement. It can be cold started and immediately driven with absolute linear result on every feature. Really impressed with the result. Power repeats to the kw every run. Knock log and protection is superb. Closed loop control, individual fuel trims etc. just work without ANY fuss at all.

I jedan post od istog tunera ( Brett), na cinjenicu da je za upload mape na Vipec u to doba trebalo 40tak sekundi (danas je to 10sec)

Long upload times?
I must say that it is the A brand that spoiled us with this and we must not forget the others that are no better or actually worse in the upload times or other operational annoyances.
Try the Motec M800 that will stall or run very rough when you highlight and change a larger group of cells, or that will not allow percentage changes or that has a PID idle control that will take you between 1/2 a day to 2 days to make NEAR FACTORY but never as good as factory, let alone Vipec refinement!!!
That is just some of the stuff we forget we are dealing with when using the V series so be patient as I am sure all will be sweet in time.
Try opening the software twice and comparing files this way. It is really effective but not possible on many other brands.
Try waiting for the Wolf ecu to load etc.
Try making changes on Nisstune then having to send them each time rather than actually having a result.
Try mapping Ford factory ecu where the laptop does not even connect to the car. (Thousands of maps with no tracer or any input at all unless you use their separate logger and interpret the data into each relevant map that may not actually be correctly labeled or actually work.) Try waiting the 3.5 minutes to flash this data to a box so you can then wait another 3.5 minutes to flash from the box to the car. Imagine how much time can be lost chasing an idle issue when each step takes this flash time + your laptop time?
Not saying many things could not be improved but it is really a small pennence to pay in the short term.
I have not found 1 perfect computer after market (Or factory) but this certainly comes closer to it than most.
Pogledaj si sto kaze o motecu, a ja osobno imam 4 auta na motec i svki put kad online selim mapu, sve se strese i crkne. CRKNE.
Kad ce vipec biti na trzistu toliko godina kao Motec....onda cemo se ponovo razgovarati o featurima.
Da ne bi bilo zabune, ja Motec smatram jednim od najboljih, ali ipak Pectel SQ6 je za 5 kopalja bolji za manje novaca.
V88 itekako mozes usporediti sa M880, a da ne kazem price-wise.
I za kraj da dodam, misljenja koja cijenim nisu misljenja forumasa koji su napravili 1 ili 2 auta od 150ks, vec od ljudi koji svojim radom na tuningu zaradjuju svakodnevno za kruh, poput gore spomenutog Bretta iz APE, ili Johna Reeda (btw, jedan od najjacih Motec tunera u USA, Red R Racing). Koliko vidim tebi ne nedostaje iskustva, ali kako nijedan TVOJ automobil koji si napravio nisam vidio, ne mogu te uzeti za ozbiljno. Ipak, sve nase motore sastavljamo sami, dajemo garanciju, mapiramo na nasim valjcima i cestama, te popravljamo za drugim tunerima svakodnevno. Nismo bez gresaka, kao niti itko drugi, ali zato je tu garancija, 24h podrška za sve stranke (slovenske, hrvatske, srpske, bih), te za nas NEMA radnog vremena od 8h. Mislim da to dovoljno govori o našoj ozbiljnosti kao i o našim proizvodima.
