the latest turbosmart FCD is a much better unit. it doesn't just clamp the signal. it clamps it at a set voltage, but allows you to keep the signal rising. you just bend the afm signal until it no longer hits r&r.

this will allow you to gain power even if you haven't hit r&r because it is leaning out the mixture. it works off a system just like a safc.

yeah as mad and the others have said just get an safc of similar device

make some more power in the rev range and avoid r&r at the same time.

magazines often leave out important facts or put down big power gains to little $5 devices, and not revealing the true gain of power.

OK so humor me then. When i did the tune on my computer, we actually had to add fuel at 4500 rpm, so now it hits boost cut, if i get rid of fuel through 4500 rpm with my safc II, it will remove the cut as the ecu thinks less air, correct. Dam it, if so i'm going to ritchen the map by increasing the fuel pressure and then back everything off in the SAFC II to get rid of R&R. Correct.

      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.
