afc neo

[connorling]

hey, i got the Apexi afc neo installed myself, wanna know how to set it up.

if anyone has tune it, can they type out the setting, so i can copy :P
thr point, air map correction, V/T control and V/T unmatch......

thanks

every car/engine is different...........you cant just copy someone elses settings and that means ur car will be fine.................

it must be tuned properly on a dyno.......................

[connorling]

just a reference point tho
at least i dont run too lean or too rich ......

at least i am somewhere safe

also is it true that if tune the afc, the ecu wil just reset to original setting???

[connorling]

anyone?

Hey mate, afc is just a piggy back where it overwrites the stock ECU. Once afc is unplugged from the ECU, the engine will run what the ECU tells it to run. ie, the original setting of the stock ECU. Unless you are using OEM ECU like hondatas then it'll be a different story. Because hondata ECU are tunable ECUs. And the settings are saved in the ROM. Guys, quote me if I'm wrong. That's what I know about ECU and AFC.

if you want to tune the AFC neo yourself, i would also invest in a wideband. youll have constant air/fuel ratio readings, so itll be much easier for you to tell where your running either lean/rich. great investment...

you cant just use a wideband.
you need a datalogger to log rpm vs afr then you can finetune your afr.

otherwise pay the money and get dyno time to tune yourself or pay a tuner to tune it on a dyno.

Yeah, I reckon that paying a tunner to tune your AFC shouldn't cost you much.

AFC does also gives u constant a/f ratio as well. in afc it uses the term afl

You can't read the AF ratio properly using the stock narrowband sensor using the Neo because all the sensor tells you is "ok" and "fcked". You need to dyno tune, where they stick the A/F sensor up the exhaust. Not as good as a wideband sensor, but at least better than trying to read A/F ratios off a narrowband.

tailpipe sniffer is also a wideband os2 sensor

[aaronng]

Not as accurate because it is post-cat. Pre-cat wideband is supposedly the best.

[dundas]

mmm pre-cat :)

just get it tuned properly, don't know where you can do that in perth, but i got mine done for a reasonable price @ toda
