Quick question about the optional driver box for the V44 , does it have peak and hold drivers for four injectors in it or is it just a resistor box to limit current if you use low impedance injectors ?

It would be nice if the V44 was available with the 10a peak and hold drivers , can they be a special order that way ?

I can't get into their forum or I'd ask there .

Cheers Adrian .

one little quibble I have with this ecu is the fact you cant select between low/high impedance injectors as you can with many of the other higher end ecu's

are there any explanations for this?

you can with the v88...its only the plug-in boards that have this feature missing.

a solution may be on the cards for this issue

Cool I will look forward to hearing more but for now I'm just going to use a resistor pack.

oh ok good to know!

With the vipec plug in, does it use the V44 boardin your standard casing? also will it support standard GTR injectors, because from what i read, it has some problems with low and high impedance using resistors. because if my afm are buggered im seriously considerign getting on of these, but only if itll run with a stock car once tuned.

Yes, yes, no and yes.

This ecu has been given the honour of being named the "Best ECU" in the latest "Best of the best" High Performance Imports magazine.

The real engine management "leckies" would know for sure but my research leads me to believe that the peak and hold circuitry is different to the saturated system .

PH injectors I believe tend to be low resistance high current ones where saturated ones tend to be high resistance low current .

I've been told the quick dirty method of running high current injectors in a saturated system is to splice in the resistors but you don't have the peak and drop current to snap open and hold the pintle pin like a PH system does .

I did actually speak to Ray Hall and his response is that the V44 is aimed at a price sensitive market segment and I gather to be price competitive had to sacrifice the peak and hold injector drivers and go with the more common trend towards saturated injectors .

Please do NOT make the blind assumption that I'm saying the product is cheap and nasty , the trouble is that so many buy everything on price and if it was made in Xxxxx and sold for $4.99 lots'd buy it .

Something I did read in Honda circles is that someone out there is making good reliable 1000cc saturated injectors and apparently they at times work allegedly better than existing PH ones .

My problem was that getting "affordable" hose barb/tail saturated injectors is not too easy where PH or high current ones are easy and cheap . No good for a wire in V44 though .

My answer could be to use Mazda Rotary turbo O ring injectors and machine shallow rings into them for the short length of rubber fuel hose to bite into under the clamp .

If I could buy a V44 with PH drivers/circuitry I'd do that so Guilt - spill the beans .

He can't "spill the beans" but lets just say the Vi-PEC is evolving. This has been deemed necessary to completely separate the product from another one similar. A lot of the Vi-PEC intellectual property will cease to exist on the similar item. The Vi-PEC brand will be regarded as a world leader in ecu technology and needs its own identity to achieve this. I am of the belief that a lot of features are being held back until the evolution is complete.

I already think i may have said too much...enough for now.

Maybe i should wait for it to evolve and then pick it up with all the gucci stuff.

the chipset will be no different...its just a firmware upgrade and new tuning software if you have already have a Vi-PEC.

The whisper is the new tuning software is the ducks nuts.

I really should STFU...lol

You can call it want you want but the vipec engineers are still the same bunch of engineers that work at Link electro systems NZ. Its funny you call it "Vi-PEC intellectual property" but then there was nothing wrong with giving Link an sm4 plus someone elses "intellectual property" data and telling them to pull it apart and do better.

This does mean the worlds leading ecu will still be made and designed by link in NZ with a few wants put into it by vipec. Do you think Link would want their ecu disadvantaged over the vipec "version" This would take a good sum of money to pass into links hand as remember its them doing the building and designing with wants from vipec. Vipec cant and doesn't make ecus !

Also remember there are ecu's out there that make Link g4/vipec ecu's look very very simple and always will, a vipec will never be the "best" or have the best best technology compared to the likes of pectel or life racing ect...

    • Morning all, I have an RB25DET Neo that's in need of a rebuild. Will need new pistons etc due to detonation damage. Would anyone be able to recommend a shop in Southeast Queensland who I could bring my long motor to for a rebuild? Just want someone who knows RBs and whos built a bunch of them before. TLDR - recommended engine shops for RB rebuild.
    • Gday Thought it was about time I started a build thread! As expected this project has snowballed into a huge financial liability, but unless you’re strong willed and responsible, it’s not a surprise. Background -  My first turbo car was an R32 GTS-4, got my full license and then totalled my Au Falcon a week later, so while trying to sell my RMZ450 dirtbike to buy another car a bloke offered to swap the R32 which at the time I felt like I was ripped off but looking back and seeing prices of those now ($40kish) it was a good deal, I didn’t know enough about these cars to appreciate what I had so sold it before the RB20 blew up. Between here and there, out of 12 cars I’ve owned the note worthy ones are a V8 Lexus SC400 (soarer), a couple of XR6 Turbos and my beloved S15 which I had for about 3 years, picked it up for $12500, repairable write off but she was fine, gun metal grey/pewter and bone stock/unmolested until I got my hands on it. Ended up spending about the value of the car and 280kw, 2 demerit points by the time I got defected and sold it for $14500 (also $40kish in today’s market, rip) Fast forward to the present day, I’m in a much better position financially and daily an MQ Triton (great cars, pipe down Ranger Bois), I cruised marketplace and car sales for a few months looking for another R32, the best deal I could find was an absolute rust bucket half finished project for $12000, until this R33 popped up in Port Macquarie for $18k - unregistered and barely running but decent shape, kept an eye on it for a few weeks and the price steadily dropped, $16k then $15k then $14k, that was the point where I was like shit someone’s gonna snatch this up! It was owned by a young bloke who had big plans but him and his missus just had a baby so smartest move financially for them but big gain for me. So 2 days later I’m towing a car trailer to pick this thing up. Roughly 2 weeks and $3500 later I’m cruising around Newcastle in my beat up R33 all smiles and dose noises! It only needed some basic shit to get it going, coil packs and air flow meter, electrical stuff and all fluids changed, 158k kms and running pretty good, nice smooth engine after oil and coolant flush - when I say coolant I mean it had been filled up with tap water, every gallery and heater element was filled with rust, 8-9 flushes later and still had brown liquid coming out but she’ll be right. The car was painted R34 Bayside Blue at some point but whether it was a cheap job or just not looked after is anyone’s guess, clear coat flaking like sausage roll.  Was rethinking my choices and contemplating life, had it up for sale for $22k - still cheaper than any registered R33 but got little interest, next minute I had an opportunity at work - 6 months overseas for good money, so that was a no brainer, fast forward again and here we are with a 50% finished project. Current Mods - 200ish KW according to butt dyno Was tuned with Apexi PowerFC EBC (old school Greddy Profec)  Stock turbo (more shaft play than a Tinder date gone right) 3inch turbo back Varex muffler  Aftermarket injectors of mystery size, Power FC showed 36% duty cycle at full boost so not behd good size Someone had good intentions but stuck with the stock R33 MAF so we had misfires at 6000rpm due to the MAF hitting 5.2V So far I’ve redone the entire interior with carpet form Car Mats Direct, new Seats and steering wheel from Autotechnica, also sound system by Autobarn (mainly Kicker) Also MCA pro comfort coil overs - Hands down best purchase yet, worlds of improvement over the tired 30yrold shocks Goals - 450kw/600hp on flex tune New paint job - Midnight Purple 2 Engine is at the shop getting rebuilt with forged rods a pistons, new valves and springs, ATI Harmonic balancer, Aeroflow 7.5L sump, rear head drain and oil restrictors as per oil control thread* and cam covers modded for larger breathers, other stuff I can’t recall of the top of my head Parts purchased and to be installed once the engine is done -  Engine loom from Wiring Specialties including these options: Haltech Nexus S3 R35 Coil pack conversion  PRP Dual Trigger kit Fan controller  Other Parts -  262 Kelford Cams Turbo - Hypergear ATR43SS3-ProS with T51R mod (whistly boi) 6 boost manifold (high mount) 50mm Turbosmart Pro gate (plumbed back for legal reasons) HKS Super Turbo Exhaust with High Flow Cat Custom 3.5inch dump and front pipe 1500cc Bosch injectors  Fuel Pump walbro 525 Haltech MAP and IAT sensors Haltech Flex Sensor Fenix Radiator with dual thermo fans LS1 Alternator Kit Oil Filter Relocation from EFI solutions and Cooling pro oil cooler Many other things sitting in my garage waiting for that engine to come back. Progress pics to follow -  
    • Losses have to be less with DC coupling. Provided the battery inverter has decent MPP tracking ability - which really shouldn't be a problem. It's not 2005 any more.
    • Hi, Will the R33 GTR rear brake backing plates fit a GTST? I'm struggling to find GTST ones but can find new GTR ones.   Thanks.
    • I also got the same floor mats for a bit of extra bazzaz haha
