Hi,

Just quick q. Does the power fc save settings so when battery is disconnected do any settings get lost? Also does blitz boost controller lose any settings? Anyone know how to recalibrate etc if needs it?

I am pretty sure it saves them but just making sure.

I am pretty sure it saves too. I have had the battery disconnected for a week while my car was having a manifold fitted, also while the car was in a paint shop for 2 weeks and the settings remained.

To reset, you need to go to the etc menu, there is a reset ecu function, just go into it, select next, then turn the ign off and on again and you are back to base map.

if you have a look a the apexi-usa site (http://www.apexi-usa.com/electronics.asp) they have a downloadable pdf of the manual for the hand controller. It is for the RX-7 but most functions are the same for R33

The Apexi electronic gear all use static RAM, so your data is safe unless you force it to reset, or zap it or something.

I would keep a backup copy of all settings anyway, just in case someone accidentally resets it, or you alter so many settings that you can't remember how to put it back to where it was if needed.

Yes, probably NVRAM ;) The stuff that needs no battery anyway. It wouldn't be an EPROM, because these can only be programmed so many times before you can't write to them anymore. If they were EPROMs I'm sure we'd have heard of more reports of failed units due to exceeding their programming limit. On top of that, EPROM burners are expensive. To have one in every unit wouldn't be cost-effective.

The reason I think it's SRAM or NVRAM or whatever is because I've had a look inside my S-AFC and there was no onboard battery. There's no reason why their other gadgets would be any different. Also, if it did use an onboard battery like computer motherboards, I'm sure we would have heard of more settings lost (as if it were an EPROM) as the battery went flat in a couple of years.

      Help Understand GTT Boost Setup

      I have always resisted the urge to go silly. 8" wide wheels and street friendly spring rates? Check. (Let's not talk about the steadily increasing spread of spherical joints across my suspension!!) Stock turbo, run at 12 psi? Check. Lasted for ?10 years before it died. Highflow put on rather than seizing the opportunity to go G45. You don't need 300 rwkW, let alone the more massive numbers that seem to be essential these days, to have a car that is already way too powerful and fast for a streeter. ~250rwkW is fine. I've never exceeded 200, although I will sneak up above it if and when I manage to get my finger out and do what needs to be done to use the highflow's capacity. You don't need $10k worth of CF bits glued onto the outside. You don't need razor sharp ankle cutting front splitters. You don't need the car to be 2" off the ground. You don't need flawless paint, mirror finished wheels, brand new indicator lenses, etc etc. All these things just make the car impractical and will cause you pain when they get damaged, which is inevitable for a street car. A few nice additions are good. Good seats are good. A nice stereo is good. A/C is good! (46° on the road yesterday and my A/C is degassed again. Was moderately traumatic driving home!) The main reason I stick with a mildly modified old Skyline is that I have had it for  >25 years, the mods are the rolling result of 25 years of things dying and being upgraded opportunistically, coupled with a few "just 'coz" ones. And I hate modern almost all cars. If I was a young buck starting out now.... I wouldn't bother. Cars have a few years left where there is any possibility of interest or fun. Thereafter there will be no such thing allowed or possible. Any time, money and effort spent now on a project would just be a waste.

      Wont start unless i have the pedal to the floor

      Let's be wary though, if cranking is so far off, what else isn't set right? Are the dead times set right, voltage compensation etc?   It definitely sounds like it's cranking fuel issues, and holding flat to the floor is shutting them down, but I'm with Duncan that if nothing was changed in the ECU at all, and then this started, I'd be more thinking a leaking injector.   Do as Duncan said, drop the oil and make sure it's not full of fuel.

      Yeah if the goal is to drive something then modifying a car is a bad idea.
