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.

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.

      All the best with it mate. Hopefully no dramas. I found quite a few issues when i pulled mine out eg fkt trans and engine mounts, throwout bearing, i had not been aware of, so 'any car maint' can be worthwhile it seems.

      I think it's the alternator, there's some cracked shit going on with the rectifier. But so far, seems to be fine again? No sparks, no weird arcing when the leads went on. I ran this past a mate, he said he had similar issues before and his auto sparky replaced the alternator. All I know is, car works, car not on fire lol.

      Brother-in-law's workshop. And I'll be doing. Family doesn't get priority over long running customer jobs. It wouldn't normally take so long to get to a task of mine, but there was a series of unfortunate events involving the dyno (blowing it up) that caused a serious backlog in the normal workload, that has toaken literally forever to get out from underneath. I can't do, or more to the point, choose not to do, jobs at home that require tools I don't have or would leave me without my daily if something goes wrong that thwarts me. Gearbox out on the floor with chassis stands is not palatable when I can use a hoist at the shop. But I've only had the box for a few weeks. It's the injectors and AFM that have been waiting on access to the dyno.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      Welp, I have been driving it around (a bit) and messing with idle and return to idle characteristics. This is all well and good until I discovered my starter motor... is nearly dead. This is unfortunately after I booked my exhaust and tune in. This is the new section of my exhaust, after losing my mind with vbands and clamps. Yes I now have 4 mufflers. The two middle ones are 5in body 3in pipe round straight through mufflers or incorrectly named 'resonators' whatever you want to call. How does it sound? Muffled.   Car runs richer now in low load. Is it restriction? Or lack of exhaust leaks. I also figured out a way to make the Analog Readout match the serial WB Readout. All of this requires a car to you know.. *start* to tune the maths, which was not ideal when I needed it to get to the exhaust shop and back. It started when cold. 30 mins after the car got home, it was time to get stuck into it. Unfortunately this thing has no identifying marks on it at all. I contacted Mal Wood and asked if he could send me a replacement and he asked me to remove it because they've changed starters with their kits a few times over the years. I asked other companies with LH LS starter conversions and they all use different starters unique to their kits. I did find CAE performance supply Mal Wood - But they are out of stock for this starter for the next 3 weeks. The tune is booked for Friday 30th. Here's hoping the local starter motor repair place (which interestingly has a 5 star review from Trent @ Chequered) can get this rebuilt/sorted out so I can get it on and put the car on the dyno. Here's hoping!
