I am going to order the TC2 v2.5 for my impreza'99 2.5RS automatic! Is it a good chip for my car? Any comments would be great. Thanks.

I can get the Apexi Super AFC (Air Fuel Controller) for about the price of Torque chip 2 v2.5. So I want to know that are they both function the same? And which one should I get?

Well, JC Sports is out of business, so I wouldnt buy a TCII. I'd buy a S-AFC or PROECM or both instead.

TC2 isn't made by JCS, never was. IWTU Electronics made it for jcs, but they stilll make them for Subaruplanet.com, SDR Performance and PDMturbos.com

It is comparable to the ProECM, of which both work great on an automatic

As it's been pointed out.....the T2 is made by IWTU electronics. I know personally the guy who makes them. He's a good guy.

One of the main addition or upgrade to the latest version is the ability to control timing advance of the ECU. This is particularly important for N/A cars that have been turbo charged. I believe there is one or two more additions. Check out their site for more info. www.torquechip.com

As far as will they do the same thing. No, the S-AFC is mainly an air/fuel controller.

The chip will alter the ECU's learning path, so over time you will get different a/f mixtures vs. stock........but won't give you the control that the S-AFC will.....but there are other issues about the ECU learning around the S-AFC......but that's another issue.

isnt the SAFC suppose to alter how the ECU operates in open loop situations??
u mean whatever settings i tune now while become null in a few months time and not because i'm used to it?

From what I've heard & been told is that ultimately the S-AFC will really only consistantly help things when you are in open loop or WOT.

I think one of the big reasons people started getting these things was that when running intakes, they found their cars to be running really rich. So they would get the S-AFC controllers to help lean it out and make the a/f ratio closer to stioch. After time they found that the settings they put in to help lean the car out was not enough.....the ECU kept richening things up during closed loop, i.e. normal driving.

I'd do a search in here and engine mang. forums and see if you can find some first hand accounts from people on their experiences.

thanks, man at least the above point is consistent with what i heard and read. where as for closed loop i dun think the safc can help. anyway for the imprezas overall anything below 3.5k rpm is already pretty lean, its the high rpms that's always running too rich
