PowerFC Map Tuning - Reliability?

Hey all,

When using a PowerFC, are you running a lot more of a risk of detonation because you no longer have the protection of the stock ecu - SAFC combo which will protect the car by pulling timing when it senses knocking?

Does the PowerFC still use the knock sensor to protect the engine to some degree??

When an experienced tuner tunes the PowerFC, can they really map out all of the ignition and fuel maps in a few hours on the dyno? Aren't they 3D with a sh1tload of different scenarios based on heaps of diff inputs?

Is it really possible to have it all mapped out with smooth and safe results on the road??

Don't get me wrong, I don't really know, but was just hoping to get some questions answered!!

thanks heaps :D

No. It uses the knock sensor to flash up the engine warning light on your dash, at a knock level which is higher than normal but should still be safe. Thus if it only just comes on due to a bad tune or bad batch of fuel, it shouldn't insta-kill your engine. (in theory)

Yes.

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.

      Yes they do. For some maybe. But for those used the most by abusers, ie Skylines, the numbers are known. The stock eyebrow height for R32/3 Skylines is about 365/375mm or thereabouts. The minimum such heights are recorded in adjacent columns in the database.

      Hmmm, interesting. Makes me wonder whether there is bias as well. It's the cheapest fuel, so it is used for all kinds of ill-maintained shitboxes which are bound to have issues regardless. Nicer cars tend to require higher octane rated fuel and can't use it anyway. FWIW, the official NSW E10 facts page is decent.
