Why are there so few Apexi afc's being installed on 350z's?? I would think it would be a great addition for tuning. I think there is only one guy on the board who has installed one.

 

There will be others.....i'll be installing mine after my supercharger goes in.........Apex'i just posted documentation for the product on their website.........i'm sure you'll be seeing more

 

you gotta be SH!TT!NG ME! they finaly released it! iv had the afcII at my house FOREVER!!!! i just needed to get the wiring diagram! after i looked in the 350 cd manual, and cross referenced the ecm pin out, i discovered that the diagram was the same as the fairladyz!! that was like a week ago! now they released it?!?!?! ive been meaning to inastall it but i havent had time! ill keep you all posted as soon as i get it in!

 

Check the US Apex'i site.......in the documentation link........they've got the wiring and operation manuals posted in PDF

 

The reason that people aren't installing them is that you can't get that much power from the Z by just adjusting your A/F. For the cost of the V2 safc + the cost of installing a wide band 02 and dyno tuning it, you can get the Perfect Power SMT6 from me. I think the guy that installed it only got 8hp. We were able to get double that... My $.02

Downside with you piece, once its implimented... it's done. The AFC is always openly adjustable.

 

There aren't too many ECM options out there right now that are as versatile as the SAFC-II.......and if you were able to get 16HP from richening A/F mixtures, then the SAFC-II will be capable of that also......it can change the A/F mixtures +/- 50%, for 12 different rpm settings, on two different maps.......it will monitor air flow, rpms,and engine knock, and display these all for the user in several different ways.......you can view it as an x/y graph, a bar graph, an analog-simulated gauge..................the reason not that many people are installing them, is because they were just released in the US.

 

This is the link from the Apexi site.

Is it just me or is this in Japanese? anyone got a english version

 

Can it adjust timing? Becuase I don't think the SMT6 got its gains from A/F ratio, but rather the timing advance.

All the piggy backs coming out for the Z scare me a little because the Z's ECU is treated like a black box. And if the ECU does something unexpected, the piggyback will still apply it's offsets. Potentially you could either lose your gains over time or induce knock.

The graphing and diagnostic features of the SAFC-II interest me though.

Ack, nevermind... only the 300 is listed.

 

Before i could download, my Adobe Reader made me download the japanese font pack, but after i did that, the manual was in english......try to update Adobe Reader first, then download

No, SAFC-II doesn't do timing......it relies on the stock ECM to do the timing adjustments.

The SMT6 is very interesting......i'll be waiting to see more about this......i'm hoping it can adjust timing, like they say.......however, i wouldn't want to go introducing timing and A/F changes without having a way to monitor what the engine does after that.

 

I downloaded the update from here

http://www.adobe.com/products/acroba...nfontpack.html

No change, still having trouble opening. Which did you install to view them????

 

on the drop downs of that page, select Japanese, Windows, and USA......i didn't download them until this was installed......maybe you need to re-download in order for them to be converted?

 

I keep trying to install the acrobat reader updates... says they are properly installed.

Then when I try to open the pdfs from the site, I'm still getting the errors.

 

PM me with an email addy........i'll try to zip up the pdf's i have and send them to you

 

Wouldn't you believe when I finally download the PDFs to the HD I can open them fine...

Too wierd.

Hopefully I'll get one of these ordered this week.

 

even if i do find time to install it, ill NEVER find time to tune it!! i might just sell it and get a plenum!! its a quick install, and doesnt need tuning to make power! ive been meaning to get one for a while!!

 

Thanks Evil. Worked a charm

As posted we got our gains from adjusting A/F ratio and timing. The smt6 does this by monitoring the crank shaft sensor siganal and sending new signals to the ecu. The safc is not capable of this making it very limited. We actually went very conservative and still got those gains. You would be surprised at what we were able to get but we decided to come up with the perfect map which sits evenly between realiablity and drivability. Stay tuned for more updates!
