Yeah, I know who does most of your stuff Al; I was talking to the other guys. I expected as much. What boost levels are you running, Al? What boost controller?

 

I am running 20 psi boost which falls off slighlt to like 18.5 at red line - HKS V

Do you have that gauge A pillar pod in stock - is it a generic unit ? please advise - thanks

 

Ah, yes. I neglected that question; sorry. The A-Pillar cover is custom for the WRX on the webstore. I am looking into getting a custom cover for the Lancer. Does anyone know if the regular lancer sports the same a-pillars? We have speakers in them as well...

BTW, I'll sell this S-AFC2 for $300. It's mint condition; I simply hooked it up to make sure it works on the Lancer and to get wiring specifications for everyone. Next I'll be doing the Profec E-01 and eManage thing. Hopefully have dyno tuned maps for everyone as well to go with the Quantum Downpipe and Catback. BTW, I can get HKS Racing Suction intakes, etc as well.

Bump.
Talked to Buschur Racing. They mentioned they got 30 whp with an AFC...

Hy I come from Switzerland and yesterday the S-AFCII with my Evo VII installed. Installation goes quite simply.

With settings to be suggested of apexi runs evo quite liquid.

Which I understand not yet completely am the Knocksensor. How do I have to judge? How much may it indicate? And how do I have to adjust it in the Knock setting? 1300 Rpm and 3500 Rpm under read or in the no-load operation?

Greeting daniel

 

If the Evo ECU is like the OBD2 DSMs, the ECU doesn't output the knock count, so you won't be able to get meaningful output from the S-AFC 2's knock counter. Your best bet is to hook up a logger than monitors timing, and watch for the ECU to pull the timing during WOT. That means it's seeing knock.

 

Any one know the correct or optimal voltage reading when looking at the regular and wide band a/f ratio devices?? I am trying to install a tech-edge wideband a/f gagues with the honda o2 sensor. "Lamda" I am tunning with the emanage instead of the s-afc, and I am a little confused for what reading "voltage" should be consider correct... I know by looking at the EGT is no more then 700 degree.. any reply is appreciated..

WRC VII - The SAFC2 reads out the value of the knock sensor. Knock count is simply how many times the knock value exceeded the specified limit for the particular rpm. You should have two points you can specify for the knock limit. From those two, the SAFC2 draws a straight line to get the knock limit at any particular rpm. Every time it exceeds that value, you add one to the knock count. This is my theory based on other standalones I've setup and tuned. I cannot say what proper knock limits you should have. Simply watch your knock number from the sensor check screen to get an idea of what your numbers are. Plot them out on a graph and then try to draw a straight line (not necessarily horizontal) above that that you consider a dangerous level. Set your two knock limit points then to define that line.
Again, that is what I would do.
CornerHard - The SAFC2 reads directly off the knock sensor, not the ECU's knocksum.
wing240 - Narrowband oxygen sensors don't have a linear correlation between A/F ratio and voltage. You won't be able to interpret a narrowband like I think you are trying to do. (I know because I have an e01 and I'm going to put an emanage in soon; that's all the more the LanEvo should need). The wideband kit, however, should spit out a linear voltage signal. You will have to look around for a comparable correlation. I know a lot of Supra guys have been defining Lambda vs. voltage for their AEM ECU's. It won't be exact but you may be able to try out their maps for the NTK sensor, etc. Try out www.supraforums.com and you should get some info.
Directly from the tech edge site:
Therfore, at zero voltage, A/F equals 9:1. At 5 volts, A/F equals 19:1. That isn't as precise as some of the maps that the supraforums guys are playing with (they are using about 10 points with linear interpolation between them instead of 2 points with l.i. like the emanage uses), but it should work.

From what I gathered reading the DSM boards, this isn't going to be too useful for tuning. Since the knock sensor is basically just a microphone, what we're really interested in is the ECU's interpretation of the knock sensor. Unless the S-AFC 2 is interpreting it in exactly the same way and at the exact same speed as the ECU, it could be getting very different knocksums, which would be misleading.

Once again, this is just what I've picked up out of technical discussions elsewhere. There were a lot of 2nd Gen DSMers disappointed that they wouldn't be able to get real knock counts with the S-AFC 2.

 

That really sucks for you guys

Hopefully whoever comes out with datalogging software for the EVO will be able to detect knock sum like the dsm link does.

 

ALL I am interested in - is IF there is abnormal knock ativity

Havn't seen the unit yet (will have it later today) - but all i am really looking fo ris a way to see if the knock count suddenly goes up in the middle of a pull - that way i can tell if there is some detonation

If this thing is not good for that - I'll just get another knock link - that was great

Also HKS is comming out with a knock deterctor product soon

 

HKS should have a GT intercooler out for us soon in the USA. Should be GD first then CT9A right behind it.

Al, I have knock link laying around if you need it. I have bin using it with the STI senser on my WRX. PM or email me if you want it. I would like to use the new one from link with a dail. ( Looking for a Vendor that carries it)

Do you also know if the new S-AFC uses the factory knock senser or does it come with one from Apex'i?? Can you control the sensativity with the new S-AFC for knock count??..

Eric

 

I will know more by later tonight !!!!

Are you in the evo world now also?

 

,

Ya, kanda I'm waiting on my buyer of my REX to come throw and I will be picking up a EVO when it happens. I'm really not into the STI just because I would like somthing completely diffrent.
