just bought one off of a friend for $100. just wondering, is each click + or - 1 psi?

also, how hard would it be to get the spring in the actuator adjusted so it runs minimum only a few psi? and then have the higher stage set at 10? be a bit better for fuel economy? thanks

No it's not 1psi - they "vary" at best. I believe its a full turn for a PSI if memory is correct.

But they are a shocking boost controller (a turbotech valve for $30 is better as an example).

Fuel economy is controlled by the right foot mate, not how much boost you are running.

I can get 550km/s to a tank with 270-280rwkw @ 17psi or so. RB25 and RB26, both returning about the same.

So clearly showing right foot and driving style play far more of a factor.

when you make it 5psi or whatever, you end up putting your foot to the floor to go anywhere meaning you end up sucking more juice or just leave it on "hi" all the time making this whole "dual stage" nonsense silly in your average street application.

      S1 Autech 260RS Wiring Diagrams

      By ARB26 · Posted

      Newbie here, proud owner of an Autech 260RS. I'm on the hunt for wiring diagrams specific to the 260RS, particularly S1. I've ran my eyes through R33, R34 Diagrams, there are some similarities, however continue to find incorrect wire colours and pins on connectors in the 33,34 diagrams.   I was hoping someone could point me in the right direction? I'd be happy to pay for the originals in Japanese. I can translate them, at least they would be accurate.   Any help please would be greatly appreciated, never heard an RB26DETT before let alone driven one, and I've got a spaghetti monster of goodness to sort out.   Cheers Benny

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻
