fitted an safc2 recently and had some trouble with it, would like to wire in a switch so it can be turned off and return to the afm wiring going straight to ecu, without having to pull apart kick panel and wiring every time. Was thinking of an on-off-on toggle switch to divert the afm signal, have it run either straight to ecu or via the safc2 at the flick of a switch. Just wanted to know which would be the best way to do it for the safc side. Would I divert the signal before it goes to safc and have the return constantly spliced, or divert the return and have the ingoing signal constantly spliced? I'm thinking divert the return signal, so the signal altered by the safc doesn't actually do anything. But not that up with wiring so open to opinions and suggestions on the best way to do it?

agree it makes no sense

either use it and install it properly

or dont install it and dont use it

but if you realllllllly wanted to do that then you would use a pair of relays on a toggle switch

my a-lsd is setup like this

Get it tuned properly for your set up and leave it as is...

I see no reason why you would want to use it sometimes and then not

Anyway there is a function on it that lets you bypass the correction made(flatten it) and the reload it by holding down the button again on one of the screens......cant remember exactly which screen right now,, get the manual and read it up

ok - not that I should have to explain myself, but, I do alot of very short trips for work, driving around 45 secs here, 60 secs there, which is hard on the battery to get charged properly....and running things that draw extra current like elect boost controller and safc drain the battery even more. So would like to be able to turn them off for daily driving where I don't need more power, and just run them for when I am going for a "real" drive. That clear it up for everybody?? :banana: As said in the original post, I'm just after help and opinions on how to wire a divert for the afm signal, as the on/off part is easy enough to sort :P

that is the most random reason for turning off a device i have ever heard

when the cars running the safc would use bugger all voltage off the alternator

i found in my 33 i have amps that run direct to the battery

these are what kill a battery in an r33

      Unknown sound similar to BOV on positive boost with partial throttle RB26

      My thinking is that if the O2 sensor is shot then your entire above described experience is pure placebo.

      Steps to DIY sanding car back ready for respray....

      By silviaz · Posted

      Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.

      Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol

      remote oil cooler hose size, 8,10 or an12?

      By MBS206 · Posted

      -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.

      Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go.
