There was a bloke in Sydney doing it for a while. But I've sent him a few emails/PM's and hasn't bothered to reply.

I've heard that the biggest hurdle is working out the programming for it, as using the R32 ECU on the R33 uses a different K factor in the programming.

Don't ask me what this means cause it's way over my head. But it's not as simple as loading the factory R33 maps into the R32 ECU. There's other things that need to be modified in the programming to make it work.

Sadly it's not a straight forward process :)

nissan ECUs dont only have maps but have constants for different things like automatic, manual loading and many other things which no one really knows (yet)

currently someone i know is writing a software simulator to work out what everything does on an R31 ECU

K constant is for base injector pulsewidth and would of course be different between R32/R33 ECUs

Thank you Jay95R33. Hi GTST.

I can program chip for R33. It's like a min's ECU. Call one time chip.

If you change your mods I can make another chip.

But we have to import the chip from Japan each time, GTST where can I buy HITACH chip ?

I will get five chip at the end of this month from Japan and I will be able to sell programed chip. Price $350

If some one is interested, please send me PM.

I can get a daughterboard from Japan.

It's making only one company.

Cost about $300 - 350 (only daughterboard )and shipping , tax, install, chip tune.

Sounds good this^^^ one! Nothing like a little homegrown ingenuity...

but like i said before.

you wont get it right first time. You'll neeed to have 2-3 shots on a dyno to get a good tune and that (wil the throw away chip) will cost a fair amount of $$$.

But if you can get daughterboards (like mine) then that's a whole different case.

Yeah, the website was playing up last night, looked like it came through three times.

The R32 has gone to finance my wedding. I really miss that car.

The R33 is a result of finding the extra funds once all the planning and preparations were done.

I wanted my R32 back but it was to no avail.

Let's just say the honeymoon will be cut short but i don't mind.

I was so depressed without a Skyline.

    • The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.
    • When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.
    • Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.
    • This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.
    • Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
