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!

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

VEHICLE: 1989 GT-R

ENGINE: RB26DETT, 88mm bore, CR=8.7:1

MILEAGE: 127xxx Kms

OIL/WATER PUMP: Nismo/OEM

OILING SYSTEM: Tomei Orifice, Tomei pan baffle, Greddy oil cooler and filter relocation

INJECTORS: 600cc Nismo

FUEL SYSTEM: Bosche 044 in-tank

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.

HP: 390

TQ: 330

      Never ending fuel pump drama

      By Murray_Calavera · Posted

      So last night pulling away from the lights, I lost power for about 1 second. Bit weird, but I kept driving... 5 minutes later the pump completely dies. When I tried to start the car, the pump won't even prime.  I left the car for about an hour, tried to start it and it all appeared fine. Pump primed, car started, got the fuel pressure I should have.... Start driving home, 5 minutes later it dies again. I'm stuck in a shit spot this time going up hill with a car right behind me, so I just let the car continue to turn over while praying to the fuel pump gods. After about 2 minutes of turning the engine over, the fuel pump came back to life and I got home (only about another 5 min away).  So I've been digging around online, it seems like the 525 fuel pumps really don't like to be run at 100% all the time. I've found quite a few examples online of people killing their Walbro 525 pumps within about a year of usage when they are run without PWM.  So, my pump is an Aeroflow 525 (AF49-1057) and I've been running it at 100% without PWM. I'm thinking the Aeroflow 525 didn't like being run at 100% and has burnt itself up.  I really am sick of dealing with fuel pump issues, my current thoughts are -  1. Use a Walbro 450 and run it without PWM. It seems like these pumps hold up pretty well to being run at 100% all the time. I only make about 350kw and can't see me making any more power any time soon so this is probably a fine option.  2. Get a Walbro 525, run it with PWM. I know doing this will annoy me as I feel like with only 350kw, its extra expense that I don't "need" and I'll be thinking the whole time while setting it up that I should have gone with option 1. I know I'll be happy with this option when its setup and running, its only the initial setup frustration and cost as an issue.  3. Get a Walbro BKS1001 brushless pump. This is the fu*k it I'm already going PWM, might as well go full retard. This option just seems better in every way, with the only downside being cost. But I don't know much about this pump so I could be wrong.  Happy to get everyone's thoughts before I go digging around in the fuel tank again.

      Doing it this weekend. For sure this time. Thank you forum gods.  And im running map sensor now with the haltech. Still have the AFMs attached to the mushroom dome shaped air filter things

      Like loud exhausts? You could be a psychopath.

      By GTSBoy · Posted

      Actually, it is probably pretty legit. I mean, it's still woke feminazi bullshit academia, but you would have to agree that it is very likely that there would be a correlation between wanting a loud exhaust and scoring at the unpleasant end of the scales for dark triad personality traits. The fact that they found it didn't correlate with narcissism and only with psychopathy and sadism definitely shows that the loud exhaust thing is more of a "f**k you" than a "look at me", and I reckon that rings pretty close to most of the dickheads who take it to the extreme. Remember, this is correlation with tendency to be closer to one end of a personality trait scale than the other end. Of course someone who is at the literal opposite end of the psychopathy scale is going to be so considerate of others that they wouldn't even think about wanting to upset anyone with a loud exhaust. So the finding isn't that "you are a psychopath". Just that you score more towards that end of the scale than someone who doesn't like loud exhausts (on average, not necessarily even for specific individuals).

      Blitz ER34 at some point hopefully, should be allowed in Gr3 if they do.

      Blue Smoke from exhaust, RB25DE+T

      By MBS206 · Posted

      Stock R33 boost control, with the exhaust, and FMIC done, will boost creep. There is no tuning around it if it is the factory boost solenoid.   If it has an aftermarket electronic boost controller, the settings/mapping can be altered in it.   Oil could be anything as mentioned, however did it ever do it before you did the turbo swap? How much and how often did you drive the car before the swap?   I'm hinging on too much oil supply, or it's not draining properly.   To check, pull the air outlet off the turbo. Is it full of oil? Drop the exhaust at the turbo, does it appears to be oiled/coked? Now pull turbo and check the exhaust manifold, does it appears oiled and coked the same way?   Secondly, the PCV could even be stuffed / not functioning properly and will cause blowing of blue smoke.
