Did manage to granny it there with the injectors, ran rich as and was fouled to shit by the time I arrived, old spark plugs were stuffed anyway.

Just a warning on the ceffy computers, the tuner actually had to get the developer of the Nistune in to try and sort it out, apparently the ceffy/laurel computer has a slower processor than the 32 and also for some reason will not hold AFRs as consistently, I traded mine in for a manual 32 gtst computer.

Also if anyone has a 32 computer with a black (instead of blue) sticker these have a faster processor again (usually only found in the 1993s).

Currently making 197 rwkw @ ~17 psi but injectors are playing up a bit.

Is there anything wrong with running a Laurel computer?

yes the are crap, we wont nistune the A31 and C33 ecu's... we replace them with r32 ecus (plug str8 in)

All the c33 and a31 ecu require a type 1 board not the type 2 nistune board that the r32 ecus take. The r32 ecu are farmore modern and take to tuning fa better.

i have a C33 myself.

Actually these computers are virtually identical to the HCR32 ECU. Problem is that the A31/C33 ECUs dont have consult capabilitiy which was the main difference (so the normal lines for consult RX/TX/CLK dont exist on these)

Type 1 board 'USB consult' was adapted these ECUs but tuners reported AFR inconsistencies with A31s so we have dropped using the board with those ECUs in the meantime until I investigate further. I suspect some of the extra code added is clobbering the ECUs internal variables so I need to go through that ECU patch firmware again and try and workout whats going on. Would be good to get those going since I have a stack of A31 ecus here and they potentially could support RB25

      RB26 block, rb26 head

      Block bump. $400. As above cyl 6 needs bore or sleeve.

      I would think making the argument that the travel is limited by a spring flexing against a spring perch as "the same method". Later on in the document they do state that the spring can't bind on full bump travel and cannot come loose in full rebound travel as well. (which is all very sensible). The laws are actually pretty sensible and reasonable. It's just that the people who enforce and check them don't actually read them or know them accurately. "Oh, coilovers? Instant fail mate. Don't even need to look at it." - Guy who will be instantly reported by me. There is probably merit to people who do get defected for height also get defected for the suspension in that state that allows it. I did never consider the people who are complaining about coilovers being picked on are also running around at 50mm off the floor.

      Ethanol Content Sensor - Always at 11%?

      I think given SAU's knowledge of E85 we can strongly conclude that 10% ethanol in almost any situation is entirely fine. Almost all of the myths against E85 were overblown, let alone E10.

      From your link See bold text, is this referring to damper settings, if so that may a issue for "some" inspectors, I cannot see aftermarket coilovers having the evidence that "must be available that its functional performance is equivalent to the original" Maybe just remove the adjustment knows and hope for the best???? Meh 5.2 Suspension travel In all instances, modifications to a vehicle’s suspension must ensure the integrity of the system and not compromise the ride quality. At least two thirds of the original suspension travel should be maintained in both directions (rebound (i.e. extension) and bump (i.e. compression)), and rebound must be limited by the same method used by the vehicle manufacturer or if this is not practicable due to the nature of the modification, an equivalent method. If an alternative method is used, evidence must be available that its functional performance is equivalent to the original.

      They actually don't - They adhere to VSB14 rules just like Victoria. The rules are against CABIN adjustable height, and it quite clearly states that the height has to be within parameters. I asked the VASS engineer to confirm this when I got my car engineered and they refused to engineer the coilovers because they didn't meet the requirements for requiring engineering. (mine are height adjustable.) People "Not wanting to bother" with "Actually reading/knowing/adhering to the rules" should result in fines and immediately losing the ability to issue blue slips and/or RWC's in Vic.
