Help.

Here is the problem. I want a 2 stage boost controller from stock level of 7psi to 10psi, fully adjustable as i dont want to run 10 psi constantly. Now.. my question is if i tune the SAFC at 10psi of boost then when switching back to 7psi wouldnt the safc be tuned correctly afterwards?? would the SAFC makes any difference whether im running 7psi or 10 psi?

Cheers, and thanks .

the safc can swtich between 2 settings ( i know my safcii does) dunno about the safc. and i did a dyno run with 5psi difference and it didnt require me to change the safc settings, it was ok for 10psi and 15psi.

Original blue screen (not the very first one, but the one before last) S-AFC DOES NOT have the option for 2 complete sets of settings.

Its basically you tune for the high boost.. On lower boost setting, this will mean you'll generally be running richer, which is for most purposes acceptable. Its not efficient, but its the balance you have to accept.

Blue screen (yup, series 1 i guess you'd call it).. the one i have.

Basically I've run about 10-12psi high, and about 8psi low. It will run just as smoothly on the low setting, just less power and maybe uses a bit more fuel than if you didn't have a S-AFC at all.

yeaa thats what i want hippy. but pred was say the original blue screen doesnt have 2 stage settings which is safc series 1 right?

from what i know.. apexi release in total 3 different safc.

a black one (adjustable knobs) then safc series 1 (blue screen) and now safc series 2 (blue screen also)

if u are gonna have only 2-3 psi difference between your high and low boost settings, then if u tune the safc for your high setting its still gonna run preety much the same with the 2-3psi less. When i got my safc tuned years ago on high and then did a run on the dyno in high and low the a/f ratios were preety close for both settings.

Pushhead, I don't speak for everyone one, but in my experience I have never taken the car off High boost. I wouldn't bother spending the money on a duel stage boost controller. I would just buy a GFB single stage, set it at 12 pounds, the safc tuned And leave it at that. Why do you want to run low boost aswell?

    • The incentives are mostly the same, yes. Ethanol is cheap compared to the cost of doing 98-100 RON with crude oil alone. 87 to 93-94 AKI all with E10. In 2020 Canada mandated E10 as a part of their "renewable fuel standard" and is supposedly going to go to E15 in 2030. In California where there are only 8 refineries with two threatening to shut down next year it's been over 20 years now of E10 and 91 AKI maximum because there's just not enough refinery capacity or crude oil supply relative to the demand for premium unleaded fuel. And CARB's low carbon fuel standard means functionally none of the diesel available at the pump is made from crude oil anymore. It's almost all entirely 20% biodiesel blended with 80% renewable diesel (hydrotreated vegetable oil) now. The number of gasoline vehicles that support E15 or higher ethanol concentrations is surprisingly low, I can't imagine it being wise to play tricks like this without flex fuel sensors in most of the fleet.
    • It's almost certainly the same as the one next to it.

    • South Australia, which is hardly as far behind as the rest pf Oz makes out, and who is also not a paragon of progressiveness (read that as over-legislation) in the area of vehicle standards, has this to say on the subject: Adjustable coil-over suspension Aftermarket adjustable coil-over suspension components are suspension units that incorporate an external thread on the main body and corresponding threaded spring saddle that allows the vehicle's suspension height to be varied. If fitting aftermarket or coil-over suspension components you must submit an Application to modify a light motor vehicle form and a report from a light vehicle engineering signatory (LVES).
    • Hi all, Long time since I've posted here. Looking for some advice on what I can remove to further identify the cause of my issues.  I can move the passenger seat forward and back but the knob used to adjust the seat angle is pretty much free spinning, there's very little resistance.  Removing the side cover I can see that the chain is intact but the shaft for the adjustment spins without the gear attached to it moving.  What's my next step for disassembly here? Is this a common fault? Just being a little cautious as I didn't want to start removing bolts for a spring to fly out or something equally as stupid.  Cheers
    • Those above shitboxes, mediocre and above usually have a turbo strapped to them, hence the slightly higher octane is required.
