All ready to cam the teggy over the summer, but i have a question about fuel management. I'm going to be installing Crower 403's and i've got the cam gears already. Now if i get the safc then i will also need to get an adjustable fuel pressure regulator. Will the hondata s100 replace my need for the FPR? Or will i even see noticeable gains with the hondata over the safc and FPR with the cams? This leads me to another question, since the safc II allows for tuning at closer intervals and also allows for two different saved settings, is it worth paying an additional $75 dollars for getting the safc II over the safc I? So the bottom line is if i'll see noticeable gains over the safc I with the safc II and wether or not i should even be considering a hondata system. Sorry for all the questions and thanks for all your input. I just want the most performance for the money.

P.S. My car is OBD I

 

I see no need for something as serious as Hondata for a car with just cams. I would get the SAFC2 though. I assume this is a nonVTEC engine as you are looking at the SAFC over the VAFC?

 

yeah, i have an LS. So you think as far as tunability goes, the SAFC II has a significant advantage over the SAFC I? I guess i'll settle for one off of e-bay then. I was considering the hondata s100 system because the chip itself is as much as the SAFC unit, unless there are other charges that i'm unaware of (which there probably are). And if the s100 could replace my need for a FPR then i could save some money. Thanks for the reply.

 

The Hondata does have 'hidden' charges, or charges that you really don't think about. You buy the chip, you have to have it soldered onto your ECU (charge). The unit comes with a basemap that is only an educated guess as to what your fuel/timing maps need to be for you to drive the car to a tuner. You need to get the unit tuned from the basemap (charge). If you want to have an authorized tuner do it, then you have to pay their fees, if not, you have to buy the ROM editor, pocket progammer, etc. (charges).

The SAFC is more simplistic and uses your ECU for the majority of the necessary tuning. You can always remove the SAFC and go back to using your stock ECU settings. The Hondata is a 'no turning back' way to go. Once you've had the chip soldered on, you're committed.

hih man.

 

You should probably still consider a V-AFC. They come preset for Honda speed-density fuel systems, so they are easier to get up and running.

An S-AFC would probably be easier to sell later though, since they are pretty universal.

Ever consider the HKS S-AFR? I use one, it's simple and low profile... not to mention cheaper.

 

Thank you very much westcoast and thank you kai. As of now, my mind is set on the SAFC II. I would consider the HKS unit, but the lack of popularity kinda turns me away. I've had the SAFC II before so i am fairly familiar with how it works. I guess i'm just reluctant to buy another one since my old one got stolen. Thanks for all your help.

 

That's half the reason I use the HKS unit, it doesn't have the huge "Steal me!" blue screen, just a few LCD numbers.

 

You will not need a rising rate FPR (other than stock) with the Hondata unit. This is assuming that you have enough injector to supply fuel to meet your needs. In some cases however, if you are about to max out your injectors even with Hondata, you may increase fuel pressure (with an FPR). Usually that won't be necessary if the injectors are big enough.

 

Being able to omit the FPR was one of the reasons i was thinking about the hondata unit. Seeing that the price of the s100 was about the same as the price of a new SAFC II on ebay, i could just get the hondata instead of the SAFC and an adj. FPR. That was until westcoast brought to my attention that there were many other charges associated with hondata other than the initial price of the chip. So for the price and for my needs a SAFC II and a FPR should do just fine. This time i'll hide the unit in the glovebox or something. Thanks everyone.

 

since i already have this thread open... should i get a SAFC I for 175 or should i just forget about trying to find a bargain priced SAFC II and just get one off of ebay for 250 + shipping?
