I'm getting one of these for xmas and was just wondering if it is difficult to install myself or am i better off getting someone proffesional to help me. As i'm getting married soon i can't really afford to workshop it so if its easy I would like to do it myself.

Thanx alot guys and girls.

edit:/ P.S i know i could search guys but im at work and the computers at my work bite balls. Sorry for SAFC thread 2 gazzillion.

yo paul.. i just installed mine myself too.. Quite easy, theres a tutorial on here, but i noticed that the wiring colors on the R33 GTST ecu loom is totally different to the tutorial, other than that, pretty easy tho. I too can give you a hand if you want as im just around the corner in warnbro. I wouldnt bother paying for someone to do it. It took me about 30-45mins maybe to install, and im not exactly an auto electrician

how do you guys go with setting it up to get the right a/f ratios

p.s. has anyone had a go at fitting there own fmic, just got one and interested in having a look at someones car close up to see what is involved, i am in warnbro

Pal.. i'm in warnbro too. I fitted my own FMIC and SAFC2, more than happy to give you a few pointers. I got a Hybrid R33 GTST kit off ebay, and found it was pretty easy to install, but a few tricky bits that the instructions didnt tell you.

PS. you can come round and check out mine anytime, im just near the last drop. Ive just PM'd you my mobile number if you want to get in touch

As you can see by dyno graph a/f ratios seem pretty constant black line is final tune, just got it done at hyperdrive, took em about 45mins on the dyno to tune safc2. Very happy with their work

Get hold of an AFR meter somehow and only make small changes.

As an SAFC is only a signal bender for the MAF taking out fuel is done by making the ECU think its under less load,the ECU then delivers the fuel needed for that load,BUT it also delivers the timing for that lesser load meaning more timing.When im tuning SAFCs and have to make large changes I plug our Scan tool into the ECU and monitor the delivered timing often having to leave a richer than ideal AFR but that is the safest method.

  • 2 weeks later...

that included me fabricating all the pipework (made from 304 grade 2 1/2" stainless steel) and getting a friend to weld it up, im quite sure it has increased my horsepower. done a 180 degee turn on outlet of intercooler and plumbed back into existing piping (same as psiker's) had to cut alot of the front bar out and move a few things around in front of the radiator. happy with the outcome. have to get it dyno'ed again now. do you think the safc2 will need to be tuned again? and do i need to reset the computer?

    • Kinkstah, no, coilovers aren't illegal, especially as a bolt straight in. The illegal part will be if they're altering suspension geometry beyond factory limits, or the ride height is not legal.   Sounds like the blue slipper just didn't want to deal with any later possibility of mods appearing on the car.
    • The problem has always been that coilovers are able to be adjusted, almost at any time, to be too low. Most people who ever get/got defected for/with coilovers were actually afoul of the minimum ride height rule. So the interpretation by cops/inspectors was always that it is pointless to allow numpty to raise his coilovers and get the car inspected/cleared, then just drop them back down again as soon as they get around the corner from the inspection station.  This led to the interpretation that they were illegal unless rendered such that they can't be adjusted (ie, collars welded to the body, that sort of thing). That may or may not have ever actually been the official line, but I'm pretty sure it's not considered to be a solution these days. Coilovers themselves fall under clause 3.2 b of that manual, because they are an "installation of a variable ride height system" and they don't fit the exclusions in that clause (which point to air springs and other pneumatic adjusters). So, as per previous statements, they require engineering cert to be legal on the road. Once you have such cert, provided you do not adjust them outside the height range covered by the cert, you are OK. Without, you have an unroadworthy vehicle.
    • Here E10 is the cheapest fuel. And general advice is to not use it unless you hate your car. From what I remember it clogs up stuff in the fuel system or injectors?  With US/Canada being E10 across the board, does that mean that all fuel there is terrible?
    • Sorry, are coilovers ACTUALLY ILLEGAL in NSW? They aren't in Vic, as long as they retain 70% of stock travel and the car is above 100mm off the ground. Does NSW actually have a law making coilovers actually illegal? RWC/Blue Slip/Engineering people not knowing the actual f**king laws boils my blood. Demand them to point to the documentation that states a coilover is illegal. (it may exist in NSW ) Edit: I checked. They aren't. https://www.nsw.gov.au/sites/default/files/2021-02/RMS-infosheet-light-vehicle-modifications-manual-suspension-and-ride-height.pdf
