OK, I have been searching and can't figure this out, possibly because I am electronically challenged. I want to get a SAFC II o tune the AFR. I belive I need a wideband O2 sensor. Basically, my question is, what exactly will I need to use a SAFC II?

If the wideband is needed, does it have to be an entire kit like the Zeitronix one, with the WBO2 Sensor, and display and all that, or can it just be something like this wideband O2 with just a gauge? I'm sure this has been discussed before but I have looked at a lot of SAFC threads and can't quite find the answer to my exact question. Thanks

 

Do you have the RRM piggy? unless you know how to work with SAFC i would recommend that over the SAFC or the new WORKS flash, something proven. I had it, and pretry much it was useless, my friend had it in his talon and new how to use it, but he didint know what was up with it in my car, it didint seem to work at all, but it looked prety!
got the turbo couple of months after that so i just threw it in my closet

anyways... just my dollar and some change

 

that zeitronix unit is very nice, should make tuning an afc super easy. Get the ZT2 unit w/ WB02, EGT, boost, lambda, plus full datalogging capabilities. You'd be set. I use it and love it!

 

The one thing that Silens is right about is that it might be difficult to use, until you take the time to research into it and figure out how to use it. There are some advantages over the Flash and the Piggy, and those are that you have a highly customized tune just for your car. People say you can't tune at light throttle, but according to my wideband right now, you wouldn't want to. When you're not flooring it, you're hitting a 14.5-14.8 a/f/r, which is perfect for gas, and I wouldn't change anything about that.

For the S-AFC people are using either Apexi's or the Greddy E-manage. You need a wideband and a guage, but you need something that's compatiable with a datalogger. I've heard you might be able to just use a laptop and plug it into the unit, but I'm not sure. You want to be able to record you're A/F/R's at certain rpms unless you can remember everything, although I'm sure it wouldn't be too dangerous if you were to see in 4th gear what kind of air/fuel ratios you were getting and then make slight adjustments and try again. You CAN tune with just the S-AFC and a wideband and a guage, but it would be nice to have either a video or a chart that showed what you're air fuels were while you gunned it so you don't have to tune 100 rpms at a time.

 

According to the pros that know how to tune the SAFC, all you really need are the following: a pocket logger ($125), a boost guage, and an EFT guage. The wideband is nice, but totally necessary.

 

i would say safcII and the zeitronix kit would work very well. i've run safcII's on cars before and they're pretty easy to tune with. no personal experience with zeitronix but i know a few people using it and they say it's a very good wideband kit

 

Basically all i want to do is tune the fuel levels at higher rpms. I keep hearing that the lancer from the factory puts in too much fuel at higher rpms, meaning that if you were to lower that, you would get more power and a lot better gas mileage. So thats really all i want to do. Later on if I go turbo or just more bolt on parts, i'd get a better tuning device like RRMs or emanage. I had the RRM one for a while and wasnt satisfied with the small gain in pull for $500. Then decided I didnt want to mess with the software either, and sold the Piggyback. Also, what about the wideband link in the first post, can that be connected to a gauge for the AFR? Also, I found this Zeitronix kit on ebay: Here. Is that a good deal, or would it be better just to get RRMs zeitronix kit?

 

thats a nice find, much cheaper than what i payed for the same unit

 

Zeitronix with the laptop hookup is the only way to fly. If you can get it cheaper that retial, the ngo for it. I can see what's going on during testing AND I can save the logs for later viewing. The little screen won't let you do that. I don't see the need for a pocketlogger once you have the Zeitronix- I only use my Auterra pocketlogger for clearing the CEL from a bad O2 sensor heater wire and ocasionally checking air and coolant temps. guesstimating with the stock narrow O2 sensors is not even a close approximation for using a TRUE wideband. Rhyzin and I tried for over a year to make our pocketloggers give us the info we wanted using the lambda values. Once I stopped being cheap and got the whole 5v range, I had my car tuned right where I wanted it in one day of tuning.
The eManage, once installed correctly and when using a cable that works is easy to fiddle with. I recommend you spend the dough on the officialy GReddy cable as I used two clones that changed the numbers on the eManage screen but had no effect on AFR.

"Pig rich" is the term that's generally thrown around when discussing the AFR of the stock ECU. Mine would dip into the 9:1 AFR range. 12.7 is optimal for driving (power, fuel consumption and safety of the internals) while the ECUs setting of 14.7:1 is really optimal for cruising. Boe recalled a couple NA engines that had melted pistons on 13:1 AFRs.

good luck. There's lots of information running around here, too, from discussions that Rhyzin, Boe, myself and others had concerning tuning so digging into last summer and before will probably help you out.

 

alright thanks a lot, I'll be saving for the zeitronix then.
