Hey

I've been searching for a while now and keep coming up with the same old descriptions and specifications

I just want to know what the main differences are between SAFC1 and SAFC2.

I presume the SAFC2 has more load points and obviously looks different so the SAFC1.

Can someone post up some specifications..

Would you say the SAFC1 is now outdated and best to go SAFC2? I am having trouble finding one at a reasonable price and have bought an SAFC1 now.. but not sure if i should use it or what.

I mean, if there is a major different between V1 and V2, then yeah, but if its the same shit then I will just use SAFC1.

I am also referring to the blue screen SAFC, not the ancient dial version :pirate:

Don't know how much of that makes sense, I'm pretty tired, hungry and out of it, lonnnng day today..

Thanks in advance,

Abu

Basically the SAFCII has a knock sensor and the extra load points and a scroll wheel instead of 4 buttons. In the end they will get the same result - dunno how much the few extra correction points make to real world performance as the safc creates a smooth curve between points. The monitor mode may be different as well but essentially the same. I just bought the number II cos i wanted one brand new with manual etc - and for the knock but i dunno how accurate the knock readings are anyways.

safc1 has 8 correction points that can be adjusted in 500rpm increments. thats about all it does.

safc2 has 12 correction points that can be adjusted in 200 rpm increments and has the ability to run 2 maps (usually 1 tuned, and the other standard) and it has the ability to minitor knock.

safc NEO has 16 correction points, VTEC controller built in (i.e. VAFC built in) as well as all the features the safc2 has but has a colour display that kind've turns me on.

That is the answer I was looking for.

So 2 maps, 1 standard. So pretty much you can switch the SAFC2 off and you will be running off standard ECU.

SAFC NEO with the 16 points is another advantage, as well as the SAFC2 features..

Although I am just looking for something basic to do the job, so SAFC2 would be good, because I would like to have 2 maps, standard boost and high boost would work?

Time to weigh up prices and see whats available!

Thanks for your help man, much appreciated.

Neo also has no knock sensor.

the knock sensor on my safc2 was a life saver. i turned timing over a bit too much, i saw it hit 99 then started to hear a little pinging AFTER.

i set it to flash if it went over 40 knock, otherwise i would've have known and blown my motor to bits..... again.

OK so I got me an SAFCII but the whole thing is in Japanese, as it would be lol

Anyone have a English manual for one of these by any chance?

Thats the DIY I found on doing the installation so I will be following that.

Also just want to know how to set it up to run stock fuel map until I up the boost and can take it to a dyno to get it tuned?

Thanks,

Abu

in one of the menus there will be an option to "initialise". that will delete all data that has been input into the unit.

i recommend doing that and starting from scratch.

OR you can scroll through and find "file select" or something like that. this will allow you to choose between the 2 data files by going to the column which says "ON OFF" and pushing the joystick up or down to select.

this is all off the top of my head so follow it only as a general guide.

You can have it all prepared/installed as in have it clipped, femal/male plugs attatched and then plugged back into the original position. All powered up and running too.

Then when ready to tune, just unplug that 1 wire and re-route the signal to go thru the SAFC unit.

If you use the plugs supplied, no further soldering will be required to make the signal go thru the unit or back to the original position.

It'll make sense when you are doing it, I'm crap at decribing it at 5am.

Are you saying plug the male and female plugs that go into the AFM into them selves?

Once you install the safc it will just run the stock fuel map because no correction has been applied to the load points. You can have it fully installed and driving around and all it will do is display values such as throttle, air flow, knock etc. If you install a brand new safc it is fine to drive around with it untill it gets tuned because it hasn't changed anything. Otherwise if it is used just check that in the 'settings' onder 'high throttle' and 'low throttle' everything is on zero correction and you will be sweet to drive. Don't have to worry about disconnecting it etc. :)

      Out here E90s are the cheapest way into a sporty-ish car because everyone knows just how expensive the repairs can get. 8-10k USD for an automatic 335i.

      Noted. Have noticed BMW are more 'high maintenance' for sure. They've attracted my attention as I think the used car prices seem reasonable vs other options, and the extra quality overall vs a commodore / camry / corolla or similar of the same vintage is appealing, especially the interior, and they are more on the sporty side whereas the others mentioned can be more cruising or economical A-to-B only.

      Haha yeah I know, this is SAU after all, why are we talking about BMW's of all things!? I hear you on the 'don't have to worry about it' side of things. Having been fortunate enough to be have been able to buy a brand new motorbike or two...never really enjoyed them as much as I'd have liked as you worry so much about where you park it, will it get scratched, stolen, attempted theft, knocked over, etc...and yes dirty. Older less valuable bikes you can just go where you want and park it wherever and not really worry that much in comparison. And who cares if it gets dirty! Never owned a V8, and have had my eyes on VE / VF commodores for years but with their prices climbing so high, the M3 has come into focus more as prices are much closer than I've ever seen...is it a potential contender now?...of course need to factor in the S65 'maintenance' especially and like you said general M car 'tax'. One can dream anyway. But more on the reality front - did read the whole 330i thread as well and was a great read too, both threads enlightening as I've never even driven one of these cars! I do recall 330i didn't seem to have the same amount of issues for almost the same car (turbos and related differences notwithstanding)...perhaps down to getting it earlier in it's life so looked after better than the 335i? Perhaps so as your 130i has been good and quite similar, so finding a car that's been looked after well is the especially-crucial-BMW-first-step.

      Nice. Dont worry about the time of not running. My current skyline hasn't run since I bought it. About 8 years ago.

      It's also worth noting that I am heavily and unconditionally biased. I've had a lot of cars including some GTRs a fair while ago. I love my BMW's now a lot. They make no sense a lot of the time and the guys on here remind me regularly that I could get something else that does what I want better and cheaper. If you're going to take on an older BMW it's definitely a commitment. If you bail on it early you'll lose money and also the ability for it to put a smile on your face. Stick with it and it just gets better.  f**k I should get into advertising.
