it will work with series 1 auto stagea but from memory isnt the stagea plug and wiring different ? if so that would need to be sorted

antilag option is approx $100 so wont break the bank if needed

all factory sensors and triggers are supported

r34 auto and stagea sII auto are not supported at this stage and no firm eta

Finally got my R33 GTR tuned with a Vipec V88 and I have to say I am very pleased, 40kW gain over the standard computer. You can clearly see the correlation of cleaning up the AFM with the gain in power.

Full credit to Brett at Graham West Workshops. I can not recommend him enough, he is very thorough with his work and takes a no BS approach. Very knowledgable when it comes to tuning!

I can't wait to see what it is like to drive, pick it up tonight. But for now here is the dyno-graph:

hi,

not interested in power results. can you please let us know how it drives in terms of gearchange, cold start, warm start, fuel economy, how it drives with demister on, aircon on full ball and so on

Provided the tuner configured the temp correction. it shouldn't matter if its 0c or 50c

There's a thing of having temp correction to alter fuel, and as you get a hotter temp, most people put LESS fuel in, as there's less air.

The issue becomes, there's less temp difference on the radiator to extract heat from the engine, and the inlet charge is hotter, which means, you're more likely to detonate.

An AFR of 12.5, especially with a normal amount of timing, isn't something to sneeze at. It can shred an engine very quickly.

hi,

Sure, be happy to tell you however I have not had a chance to drive it very much as yet.

Gearchange: perhaps a bit smoother than before, no pops or splutters between gears especially downchanging. Drops back to idle between gears nicely doesn't even hesitate as soon as you engage the clutch and take your foot off the throttle.

Cold start: very quick to find idle, goes down in stages and once it is warm will sit at 750-800rpm. Flick the air-con on and within a couple of seconds its idling again smoothly. Same with dry steering, turning lights on, etc.

Warm start: have not done many will let you know.

Fuel economy: something I am interested to find out too, I will fill the tank up on the weekend and drive her "normally" until its empty.

Basically with any auxillary funtion on it is fine. You would not really notice the difference in that regard to the standard computer. Standard ecus are so well engineered (as car manufacturers have possibly millions of dollars to invest in R & D and engineering). For an aftermarket ecu to be better than standard is brilliant. So, knowing this I was aware of any differences between the standard ecu and the Vipec V88. I drove it to work today so I could try and find things that I didn't like and so far I havent but it is early days.

One thing I would like to say is that I would love to put someone in two different GTR's, one with AFMs and one using MAP. In terms of drivability you can argue the toss until you go blue in the face, there is no obvious difference. In terms of the things that you have mentioned Paul (ie. fuel economy etc) I am not so sure yet. This is my opinion, so those who kiss there AFMs goodnight before they go to bed don't get upset at what I just said.

Anyway, so far I am very happy, a lot of time went into the tuning as far as I know I am the first in SA to have a V88 on a R33 GTR. Will keep anyone who is interested up to date, if you want to get into more detail PM me.

Thanks for your concern. AFR is something Brett and I talked about a fair bit and yes, we went through the temeprature correction as well as insurance. I am perfectly happy with the AFR I can not see a real problem with it and I trust Brett's judgement considering his experience and knowledge.

So, thanks for caring about my car so much :starwars:

      Duncan's V37.......race car?

      By Duncan · Posted

      our good friends at nismo make a diff for it, I have one (and a spare housing to put the centre in) on the way. https://www.nismo.co.jp/products/web_catalogue/lsd/mechanical_lsd_v37.html AMS also make a helical one, but I prefer mechanical for track use in 2wd (I do run a quaife in the front, but not rear of the R32)

      R33 persistent issues. P/steering and lag/misfire

      By GTSBoy · Posted

      What are we supposed to be seeing in the photo of the steering angle sensor? The outer housing doesn't turn, right? All the action is on the inside. The real test here is whether or not your car has had the steering put back together by a butcher. When the steering is centred (and we're not caring about the wheel too much here, we're talking about the front wheels, parallel, facing front) then you should have an absolutely even number of turns from centre to left lock and centre to right lock. If there is any difference at all then perhaps the thing has been put back together wrongly, either the steering wheel put on one spline (or more!) off, and the alignment bodged to straighteb the wheel, or the opposite where something silly was done underneath and the wheel put back on crooked to compensate. Nut there isn't actually much evidence that you have such a problem anyway. It is something you can easily measure and test for to find out though. My money is still on the HICAS CU not driving the PS solenoid with the proper PWM signal required to lighten the load at lower speed. If it were me, I would be putting either a multimeter or oscilloscope onto the solenoid terminals and taking it for a drive, looking for the voltage to change. The PWM signal is 0v, 12V, 0V, 12v with ...obviously...modulated pulse width. You should see that as an average voltage somewhere between 0V and 12V, and it should vary with speed. An handheld oscilloscope would be the better tool for this, because they are definitely good enough but there's no telling if any cheap shit multimeter that people have lying around are good enough. You can also directly interfere with the solenoid. If you wire up a little voltage divider with variable resistor on it, and hook the PS solenoid direct to 12V through that, you can manually adjust the voltage to the solenoid and you should be able to make it go ligheter and heavier. If you cannot, then the problem is either the solenoid itself dead, or your description of the steering being "tight" (which I have just been assuming you mean "heavy") could be that you have a mechanical problem in the steering and there is heaps of resistance to movement.

      R33 persistent issues. P/steering and lag/misfire

      By MissMintyR33 · Posted

      Little update  I have shimmed the solenoid on the rack today following Keep it Reets video on YouTube. However my steering is still tight. I have this showing on Nisscan, my steering angle sensor was the closest to 0 degrees (I could get it to 0 degrees by small little tweaks, but the angle was way off centre? I can't figure this out for the life of me. I get no faults through Nisscan.

      The BES920 is like the Toyota Camrys of coffee machines. E61 group head is cool, however the time requirements for home use makes it less desirable. The Toyota Camry coffee machine runs twin boilers and also PID temp control, some say it produces coffees as good as an E61 group head machine.
