what do you guys think about this?..... im inclined to try it when i go turbo in a few months.... what kind of adjustability does this unit have compared to an safc?

[crzycav86]

It seems to have way more adjustability.. and the price is less than half of a used safc2.

If my hacked maf fails.. I'm definitely investing in one of those.

Thanks for the link

Bump for more discussion. I'm very interested...crazy you need to go buy one and figure it out then let us know...heh.

[crzycav86]

Don't you have any faith in my hacked maf?

Yeah.. when things turn sour, I'll get one. Don't worry about that.

..BUMP!!!1

I don't understand how you would know what load you need to be adjusting. Say you did a run and recorded it with the datalog on a wideband. You need to adjust a/f at certain rpms, but how do you know what voltage it is at a certain rpm. Unless your logger could record MAF voltages along with the a/f I don't see how it could be easy to tune. It would be pretty hard to adjust it in realtime unless your car was extremely slow. So what would be an easy way to tune it? Maybe I'm missing something.

I think they said they sold a hand held digital monitor for realtime tuning.

doesn't a safc have configuration settings for different sized injectors and maf/map sensors? If so i'd definitely say it's the better choice. personally, i think the 2 line display of this new product would make adjusting hard. not to mention it doesnt display anything other than a fuel (correct me if i'm wrong but the safcI/II can display 4 parameters at a time). from what i can see, the only advantage this has over an afc hack is resolution which btw, i think its overkill. 128*127 in nuts. that could take a while to tune. not even the priciest standalones have that kind of resolution.

I guess you didn't take a look at the price tag. You can get one for less than $100 shipped from australia. That's its main advantage, IMO. It does the same thing as the safc for a whole lot less.

I see what you mean. But I think what most people do is guess and test. They do a test. Then "guess" where to adjust fuel based on their datalog or whatnot.. and then test again... and guess.. etc.

Could that paralle connector be used to connect to a laptop? it would be alot easyier to tune and look at patterns.

[DRIFTEADOR]

actually i believe $61.56 + 46.16 comes out to a little over $100 . thats for a diy kit that you have to solder/assemble yourself. if you have the tools and knowledge all you have to lose it time, otherwise, the tools required to solder it will cost a little more (a $10 radio shack solder iron will not work) and if you mess something up by, for example, soldering at too high of a temperature you'll need extra parts. I couldn't find the price of the built kits for comparison, but a used safc I sells for about $150. and like i said, with the autospeed, if you later upgrade to bigger injectors or a different mafs you'll need to retune as there are no conversions.

s-afc display (notice the graph mode, a lot easier than looking at single entries in a specific rpm points at a time):can display rpm, throttle, air flow and correction %.

autospeed's:

you need separate tuning hardware for either, but an advantage of the safc is that your local import shop is more likely to tune it for you.

[crzycav86]

Oh. I missed that last sentence: "Kit requires handheld controller".

I guess you've got a point.. but I haven't seen a used safc2 for $150 bucks either.

[erollinc]

even if their fuel controller is no good check out all their other **** .... like boost controllers turbo timers alrmas they ahve a ton of stuff for super cheap ill probly get somethin from them eventually

[DRIFTEADOR]

agreed. wd, couldn't that universal voltage switch work as a triggering device for your injection kits?

how about a "sponsored" kit for the idea

[Warped]

[37]-KC5386: Hand Controller for Digital Adjusters 59.95 [37]-KC5385: Digital Fuel Adjuster 79.95

Subtotal: $139.90 United States Total Freight: $34.71

Prices are in Australian Dollars Order Total: $174.61

In us dollars thats only $134.67

seems like one hell of a deal to me, go buy an hour of dyno time and start tuning, or get a wideband and tune all day

LMAO...If I ever sell any kits, they will come complete.
