even though the S1 shares the same engine as the R33 models the ecu has a plug the same style as the R34/S2 ecu's. also to that, of the S1 ecu's there were 3 variations used, i think some of the guys have just plugged in R34 PowerFC's without a problem, while one of the year models is a pain to replace, the ecu's pinout is a fair bit different to the others. if your after some better info you could ask SAU members GoldZilla or Duncan. both have S1's and have had experience in upgrading/replacing the ecu's.

did you do a GTS4 stag engine conversion chris?

yep mine has a Auto C34 4wd RB25 in it. auto box long gone - grey plug on the ECU harness. need to get it working on that harness first then I will consider 'fiddling' with it.)

I've got a Z32 ecu with nistune and adapter harness for an S1 Stagea that I wont be using if anyone is interested

I've also got an R32 ecu ready to be nistuned with adapter harness for S1 Stagea

Do you have photo for adapter harness?

Who made it?

You guys might find this info useful! (only 3 ecu's on c34 stageas', RB25, RB25Neo, RB26) *S1 RB25 = pita!

Stagea ECU diagrams

Z32 uses a different ecu to the s1 stagea, as does the R32 & R33 GTST (all similar to RB26DETT, single afm is the difference) , the R34 RB25DE & Y33 RB25DET Gloria uses the same ecu as the s1 RB25DET stagea (fyi: the 98-00 VH41DE uses a very similar ecu)!

Worthy of noting is that the neo pinouts are very similar to the s1 ecu!

There is no nistune for s1 ecu!!!

ok cool info

what do u all think or know about ems 4860 ecu?

i am looking at that ecu or a greddy emanage ultimate. what would u think would be easier

4860, you would have to batch fire injection and ignition as it only has 4 drivers of each, not really a big deal. the 6860 would be better as it has 6 of each. why are you interested in EMS? i'm not bagging them out, they just aren't the most popular ecu in the RB world.

Probably should ask first if you have a manual conversion done? if its still auto you should definitely go the emanage route, you could try and piggy back any aftermarket ecu but the emanage is the best fit for the job.

yer i know all about that so annoying lol.

a workshop hear in Perth is trying to get me to buy a heltec platinum 2000 there ok ecus but its like 1850 for just the ecu.

u can get greddy emanage for half that

    • You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways. 
    • So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik
    • Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
