Half on the temp guage is fairly miss-leading.

Any one with a PFC will know that half is from ~72degree's right up until a shade over 100degree's. Only once over 100degree's will it start creeping up. :)

100% agree with you Joel. The factory temp gauge gives you three basic indications - at that's about it:

The engine (coolant) is starting to get up to normal operating temperature,

The engine is AT normal temp',

The engine is overheating.

An aftermarket ECU and handset display allows much more accurate monitoring of 'real time' coolant temp's.

While we're talking about coolant and radiators - yesterday evening I bought a new 53mm aluminium radiator from Tarek at Racespec. It was $575. (RRP $750)

See here - http://www.racespec.com.au/shop_detail.php...d39c82c9167ad0b

These radiators are made in the USA using the exact same end tank design as factory, all the same style fittings (temp sensor etc), TIG welded and run twin 26mm cores (26 x 2 = 52mm but they call them 53mm?)

Just the thing for summer... and ready for the Nationals - even if it ends up being 48'c again :)

Yeah true - although I'm guessing it's only a matter of time till cheap and nasty alloy radiators hit the market... shortly followed by cheap decent quality alloy radiators.

    • HFM BM57 has a "bad" knee point, IIRC. It's not the same thing as the later R chassis MC.
    • The ATTESSA is functionally identical to R34; there were a bunch of JDM models that continued ATTESSA including Fuga/Q70, Skyline/Q50, Cima etc as an option. All with Auto only and I think mostly for snow regions. AFAIK there were no AWD VR30DDTT sold in Australia - it is on my to do list to check regs for racing a LHD car in Targa/ATR/AASA/CAMS events because if I can get the auto to work it would be interesting to run a 4wd car The Ecuteck TCM tuning is the same model as their ECU tuning, they already have it for R35 and Dose's favourite, BMW. You buy "points" to allow your computer to be tuned, buy either a bluetooth (phone app) or bluetooth+USB+Key (phone and PC) dongle, and pay for a tune that will be locked to your tuner ( ). You can also access the tuning software yourself but 1. it is mega expensive and 2. these computers have a billion parameters that intersect, so how could you ever spend enough time on it to get a decent result.
    • Or, is it a case of what it is like owning an R series Skyline? NFI what the previous owner has done or fiddled with... Ha ha ha After reading through this thread, I went on a bit of a research about the Q50/Q60. Now I'm quite intrigued by them! Is the AWD in them more like a WRX where it's always AWD, or is it more like the ATTESSA in the GTRs? By the sound of this TCU tuning, this sounds like a case of someone has made some real software for it, and you just need the right piece of hardware, and then you license that specific vehicle/TCU. Or is this a case of the software will be really expensive so only a few tuners have it, and you still have to pay a license per vehicle?
    • By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol
    • No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
