^^^^ I'm with not so stupid.

SAFC only does fuel maps (so to speak)

I belive the Chip allows for timing changes as well.

Speak to TOSHI from these forums.

Many people have used him with great results.

Very good pricing too.

PS: 16psi on rb25 turbo hey...

Starts taking bets on how long till it go kaBLAAAMOOO

trevvy: please forgive me for hijacking but u just posted what i was goin to post...

can anyone give any insight on a unichip compared to a safc II? both can be had at the same price (roughly). safc can only do fuel whilst unichip can do fuel and timing.. are they worth it ... i want roughly a 15+ kw gain ..

edit: i heard toshi also does a remap/daughterboard for r34? anyone have any experiences? i'm interested as i want to get it tuned by the top secret guy coming to australia mid May

reason why i'm not goin powerfc is due to my car being a tiptronic

apparently u can run more boost thru the rb25 turbo on the rb20 because it isnt flowing as much air to create the same boost, big thread on it i will find it tonite

thanx for the prompt replies

Trev

I still wouldn't push it past 1 bar.

1bar on the track would be pushing it though.

I know of a R32 RB25 turbo pushing 14psi that made 190rwkw. :cheers:

For a street car, go with the chip.

There is not much that cant be altered.

eg.

LEVEL 1: speed cut change/eliminate, rev limit change, boost cut change/eliminate.

LEVEL 2: fuel map adjustment, ignition map adjustment.

LEVEL 3: rpm scale adjustment, load scale adjustment (for higher boost levels).

LEVEL 4: injector size re-scaling, AFM re-sizing.

Its all do-able, if you can fit an eprom!

Yes, the injector latency (sometimes called void blast off time) can be adjusted.

This is part of the issue with the 550cc RX7 injectors, the other is they may not be exactly 550cc/min. Hence, the injector setup parameter may need to be further tweeked for 'best fit'. It may take a few trys but do-able.

Can the SAFC2 do the following:  

1. speed cut change/eliminate

2. rev limit change

3. boost cut change/eliminate.

4. And is it possible to have both the chip and safc2 on board?

Suggestions follow;

1. No

2. No

3. No such thing as "boost cut", there is protection from excessive airflow. AFM voltage benders such as SAFC, DFA. EManage etc can be tuned to lower the AFM voltage signal to the ECU. Hence it doesn't know about the excessive airflow.

4. Yes.

Hope that was of some help:cheers:

It feels like basically you guy's are saying the SAFC2 is useless, What kinda gains can be had with one does any one hare have some real experiance with them?

What gains/losses have been seen. Cause lets face it they are a much cheaper alternative to aftermarket EM.

( I know that aftermarket EM offers alot more control and tunability but 1500 to 2000 for supply fit and tune, Compared with 500ish you can see why there would be a market for it, ( If there are gains to be had.))

I have an SAFC2 in my car (series 1 R33) i got my timing and the SAFC2 tuned and only 1 psi boost increase resulted in 36KW at the wheels increase. But to get the SAFC2 running properly without fuel cutting they had to install a FCD.

Take a look at my dyno graph. Note the dyno graph is just to show the increase its not what my car is actually making at the moment. Cheers

    • Thanks for that, I'll check it all out. I can always do the brakes last anyway if its a problem.  The 16's are super cool, if they do fit I'll cruise around with them for a bit.  
    • Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.
    • OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup
    • I forgot about my shiny new plates!
    • Well, apparently they do fit, however this wont be a problem if not because the car will be stationary while i do the suspension work. I was just going to use the 16's to roll the old girl around if I needed to. I just need to get the E90 back on the road first. Yes! I'm a believer! 🙌 So, I contacted them because the site kinda sucks and I was really confused about what I'd need. They put together a package for me and because I was spraying all the seat surfaces and not doing spot fixes I decided not to send them a headrest to colour match, I just used their colour on file (and it was spot on).  I got some heavy duty cleaner, 1L of colour, a small bottle of dye hardener and a small bottle of the dye top coat. I also got a spray gun as I needed a larger nozzle than the gun I had and it was only $40 extra. From memory the total was ~$450 ish. Its not cheap but the result is awesome. They did add repair bits and pieces to the quote originally and the cost came down significantly when I said I didn't need any repair products. I did it over a weekend. The only issues I had were my own; I forgot to mix the hardener into the dye two coats but I had enough dye for 2 more coats with the hardener. I also just used up all the dye because why not and i rushed the last coat which gave me some runs. Thankfully the runs are under the headrests. The gun pattern wasn't great, very round and would have been better if it was a line. It made it a little tricky to get consistent coverage and I think having done the extra coats probably helped conceal any coverage issues. I contacted them again a few months later so I could get our X5 done (who the f**k thought white leather was a good idea for a family car?!) and they said they had some training to do in Sydney and I could get a reduced rate on the leather fix in the X5 if I let them demo their product on our car. So I agreed. When I took Bec in the E39 to pick it up, I showed them the job I'd done in my car and they were all (students included) really impressed. Note that they said the runs I created could be fixed easily at the time with a brush or an air compressor gun. So, now with the two cars done I can absolutely recommend Colourlock.  I'll take pics of both interiors and create a new thread.
