I have no memory of the first post about the capicitors, even though I replied to it lol. I'll pull my ECU apart next week and have a look if I have the same issue. Might be alright if I just have to replace some capacitors. Just have to find somewhere to buy them. I basically only have Jaycar locally to buy these sort of things from.

You can buy single components on line from RS Components or Farnell. That's a silly extreme - you'd not buy singles, you'd buy a few of each that you need at least. But the point is you can buy small quantities of good quality components from those sort of vendors on-line easily enough.

Yeah that would be the plan.

Turboedsloth: Do you know what sort of capacitors, and how mant farad they were etc. Also how many I would need in a worse case scenario? chances are I'll order 10 or so anyway to make it worthwhile but I'd like to order now so that they will be waiting for me when I get home next wednesday

So I ended up getting a second hand HICAS ECU and slotting it in. SO far its been O.K, but I've only done a little bit of testing yesterday but didn't play up once.

Opened my old one up and all the capacitors look fine. None of them look burnt or have exploded so yeah bit strange. Was going to put a meter on them but can't be bothered if the new one has fixed it. Maybe one day I will look at the one that came out of my car and re-pairing it, but dont think I will bother really lol

Will keep this updated as i go, but hopefully its all good now. I seem to have a series 2 HICAS ECU in the car now. was one part number higher then the one that came out, but so far no problems.

Caps don't have to be too obviously damaged (ie burnt). If the top is bulgy that's a good sign. You can't actually just test them with a meter either. You have to have an ESR tester (Equivalent Series Resistance) to find out if they're still in tolerance. Bit of a pain in the arse.

Yeah thats why I'm probably not going to bother testing. Meter only shows a problem some of the time so no real point. I'll just keep running the new one and hopefully it goes alright. $50 fix can't really complain. Have another solenoid for the rack lined up anyway so may chuck that in anyway or keep it as a spare

Thanks to the guys who pointed towards capacitors and it being an actual HICAS ECU problem. I would have messed around with the other end of things if not for that so thanks for saving me the trouble :thumbsup:

      RB25 S2 Idles but doesn't want to rev

      By Trilbyte · Posted

      No intention of driving the car the way it's set up now, just wanting to make sure I haven't made any mistakes along the way so that the tune can go smoothly, I don't want to waste anyone's time with stupid issues. And of course I intend to get it towed to the dyno in a completed state 😅 I have the base fuel pressure with the vacuum disconnected set at about 40psi, which I believe is at least relatively close to stock fuel pressure, maybe I'll have a fiddle with the reg and see what happens. For all I know I could be wasting my time with this and I should just plumb it in and see what the tuner reckons. I just find it a bit strange that it seems to be under so much load just free revving, but maybe that's just a result of the turbo slowing down the exhaust gasses and making a restriction in the flow, with no boost to compensate.

      The boy just hit up google translate and it worked a treat, he said step one was "please urinate with precision and elegance", he then sent me the correct translation  I get some new loctite for the small fixtures tomorrow and get some "dort" going after that 🤣

      Right, so is the fuel pressure the same as it was previously? If not, well, it's not going to work well. I can understand the theory I assume you are going for, which is: "Run it N/A, and if I have the original AFM, and same amount of fuel and intake air as previously, the fact there's a turbo in my exhaust should still make it run" Which it... might? Provided you don't actually change how much air or fuel is going into the car.. or getting out. But if you have changed that, all bets are off. What is the purpose to even have the car run this way? To get it to a tuner? And if the goal is to limp it to a tuner, you're still going to what - plumb up a whole intercooler system and new intake in the parking lot out front before your tune......?

      Haha yea it's a bit of a weird setup at the moment, just wanted to make sure I sorted out any headaches before dyno day. At the moment I've changed the exhaust manifold, turbo and downpipe, 460lph fuel pump and rising rate reg as well as the previously mentioned headstuds and gasket. The nistune was already mapped for the car as it was and drove around for a few months no worries. The plan is to run flex fuel hence the big pump, which I've wired direct to the battery through a relay to avoid voltage issues.

      Um. Was the ECU the same as the one previously there? I know R33's needed R32 GTST ECU's or other tomfoolery to run Nistune. This is such a wild setup. Most people would plumb in the turbo then not drive the car (i.e tow it to a tuner). What's actually changed since it last ran?
