Hey all,

With a couple mods on my Stag, I'm thinking I could be doing better fuel economy/power if I did some fuel tuning. Originally I was thinking a Nistune, but looking into it, I think this is probably a little premature. Honestly, not going to upgrade much more mechanically for a while - current have a catback, K&N drop in air filter, BOV, EBC. it's gonna be a while before I look at FMIC/turbo/injectors/fuel pump. That lot would need a Nistune, in my opinion, but for now I'd like to run a good clean setup at around 10/12psi.

Have done some searching and reading and it seems like some folks are using SAFC for fuel maps. But I'm wondering how people actually tune their maps? Doing it DIY on the road? On a dyno? Using a datalogger? Laptop connection? Really interested, as I can see units on ebay for under $250 but keen to know what the best course would be for tuning it. I've read about folks pulling up to -35% off the top end of the map but I'd be concerned to hit a knock at that level, without seeing an AFR data log.

 

Cheers

I've had a safc neo, it was ok and made about a 1-2second difference to my 0-100 time. 

 

A safc doesn't compare to an actual tune. An actual tune is a lot safer, while the driveability, fuel savings and power are far beyond what a safc can do.

 

Post a pic of your car mate! Nice to see another stagea owner around :cheers: 

Because I had an auto I had an SAFC in my S1. But I also had an SITC (for timing) a Jaycar boost controller and an HKS speed control defeater so that I could exceed (on the track) the 180km speed limit of the stock ecu. Obviously this all cost more than a Nistune but that was not an option for the S1. I also paid for a tune which you need in any case.

 

If you have a S2 Neo engine getting a Nistune is a no-brainer. It will do much more  than a SAFC for not much more money and the SITC is getting really hard to find. You should be prepared to pay for a tune in any case so the Nistune is incomparably better.

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
