were selling for 1650

hoping to have the 1st few installed and tuned next week

i am hoping for the install THIS WEEK i have been waiting a week now and no contact about when it can be installed and tuned if it dont happen soon i will be wanting a refund.

a bit of communication would go a long way

according to my disto features on plug in are as per v44

so antilag is option

launch control is std

You mean you have to pay more for antilag?

WTF is this shit?

It's a piece of code, they should just f**king add it!

can someone confirm that antilag is an option? so you'd have to pay more for it? how much if so..

Just went and saw my tuner last night I am having a V88 installed on my R33 GTR.

So far has just tuned for idle and cold start and I am already impressed. Punch the throttle and it goes back to idle smoothly, sits on about 800rpm and sounds great. Software looks good too, really easy to understand.

A day or so on the dyno now and hopefully I will get it back. Excited!

Welcome to MOTEC

and in the blink of an eye the Autronic jumps lightyears ahead...

seriously though, paul can you confirm this?

also will they 'communicate' with the AIM dashes? like the haltech/autronic ecus do?

i might just ring mark in the morning

I've been running the Nissan plug-in ViPEC on my R32 GTR for a couple of weeks and couldn't be happier. I sold my PFC including datalogit and Nismo MAFs for a bit less than I paid for the ViPEC and my car runs much better.

I first installed my PFC on an OEM build and had absolutely no complaints. The car idled well, pulled hard, gave me all the control of fueling and ignition timing I needed. I added 264/265 x 9.7 mm cams and a set of GT2860R-5 turbos and everything was still great. Added HKS dumps, had some fairly extensive exhaust porting done and raised compression ratio to about 8.7:1 and couldn't get the PFC to control idle consistently. Part throttle shuffle was interfering with my life as well and could not be tuned out.

Slightly off topic rant. Skip unless you're interested in why MAP>MAF sometimes...

Root cause is that the MAF transfer function is nonlinear, and the PFC adds the raw voltages BEFORE it applies the transfer function. Oscillating airflow therefore appears to be oscillating load and the PFC changes fueling and spark accordingly. This feeds the shuffle and results in an unstable situation. If you could apply the transfer function to each MAF signal and THEN add them, the system wouldn't go unstable.

Back to the ViPEC... It uses the factory CAS without any drama. The tuning went very smoothly with autotune every 500 rpm on the dyno making short work of fueling tweaks. (Innovate wideband feeds an aux channel for great accuracy and response time) We only layered on one more dimension to manage the differing fuel needs for part throttle vs WOT at a given engine speed and boost level. The car pulls nicely from the basement right to redline.

The tune is pretty conservative running 10.5:1 at 17 psi in the higher rpm cells. More timing could be fed in as well, but the lack of knock control, or even indication of knock, makes me want to run conservatively until I get a handle on this. By the time you hear it from the driver's seat it's pretty bad... Don't want to go there.

Anyhow, here's what my setup looks like with the dyno numbers.

Cheers,

Dan

TURBO SETUP: twin GT2860R-5

MAP or MAF's: MAP

INTAKE SETUP: Apexi Power intake

INTERCOOLER: OEM

VALVETRAIN: JUN 264/264 9.7 mm lift - adjustable gears

HEAD WORK: Intake mildly ported and left rough, exhaust opened up about 15% and polished, combustion chamber polished

EXHAUST: HKS dumps, Tomei DP, 85 mm HKS Priest

BOOST LEVEL: 1.2 bar = 17 psi - Blitz Dual SBC Type R

ECU SETUP: ViPEC Speed Density

CLUTCH: ORC series 700 twin

COOLING: Greddy aluminum rad with electric fan

DYNO:

Note linear torque increase from a respectable 150 ft.lbs @ 2500 to a slingshot-like 325 ft.lbs @4300 rpm, relatively flat plateau to about 6500 rpm and only modest drop in torque up to 7500. This is without any cam timing tweaks and with everything pretty darn warm.

The car feels very alive on the road and willing to rev til you shift. :drive:

Nice conservative tune intended to let me have a ton of fun without making rebuilds my hobby.

Gary,

Which workshop is doing the tuning?

did they quote how much it cost to tune it?

Cheers

i dropped it off to Alistair @ Autoworxs this morning he is installing the ecu and loading base map then Lumpy is tuning it on Tenagah Motorsports dyno on monday morning :( yay no more afm's to worry about

will one of these fit an stagea s1 with auto? and where in melbourne would i get it tuned?

i've been trying to get a dealership as i have a few customers wanting them but melbourne is tied up with JPC and so far i have not recieved more information.... still waiting. ;)

    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
    • Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣
    • After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.
