I just posted the 05-06 tC F/IC installation wiring diagram on our website (cant attach it here for some reason).

Dezod, I have one of these for the 7th Gen as well if you want it. It wont be posted for a it since it's not yet road confirmed but it may be of some help to you.

 

Isn't that what they said about both Greddy units?...until they strapped it onto our PITA ECU?
I'm still really hopefull for this, and will go with it over the Greddy blue, but I'm wanna wait till it's actually been tested on a boosted tC.

Thanks for all the great info!!!

 

Excellent. Feel free to email that to me if possible.

Much appreciated.

 

OK, I just got a bunch more information.

I think the FIC will solve this problem. We have an O2 spoofing output on the F/IC. We dont talk that much about it because it's still undergoing testing but one of the main test mules for feature this was the tC.

The signal spoofing output is run off a 17x21 table with RPM and boost as the axis. It has 3 modes, a straight voltage out (NFG), a duty cycle and an offset voltage. In the case of the tC the duty cycle worked very well. The tC has a funky O2 sensor that outputs a current like signal rather than a normal 0-1V or UEGO sensor output style signal. When you put a MM on it it reads around 3v and does not appear to change much. We designed a high power duty cycle output mode that was shown to allow feedback all the way down to 12:1 AFR. In your case, we would simply enable this mode at positive boost levels where the O2 F/B is still active.

After putting 2 and 2 together and remembering that the tC was the one with the funky O2 sensor output, it now makes sense that the traditional o2 spoofer units are not working well at all.

I think it will work great for this app.

 

the problem with e-manage was that regardless of tuning the tC's ECU, it will eventually learn and take back control for anything in closed loop or under 4000 RPM's. it is only under WOT that the ECU doesn't fight and takeover.

 

DelSolid and myself have been discussing this at great length over PM, and he feels confident, as well as myself that this will work against the stock PCM well.

 

02 spoofing? Does this mean this would pass OBDII SMOG?

 

you prolly wont pass the sniffer test but i think its supposed to trick the ecu to think its running 14.7 when its not and hopfully keep it from throwing a rich afr cel

 

O2 spoofing would be just like the black box. The black box intercepts the signal of the front wide band o2 sensor. This allows it to tell the ECU that it is 14.7 AFR when really it is say 12.0 AFR. The ECU thinks it is trying to keep the car at 14.7 AFR but the ECU is really trying to keep it at say 12.0 AFR. The black box (and this new AEM unit) have a built in MAP sensor which would allow you to tune this according to whatever load point you wanted (for example only when you are in boost so it should pass a sniffer). Also this could make the transition from closed loop to open loop very smooth.

Now from what I am hearing right now basically the AEM unit will be very similar to an Emanage blue but with all the harnesses, Map sensor, and even a black box built in. Heck it sounds like it will control the fuel even better then the Emanage blue (but I still do not know how it exactly controls ignition). For $400 this would be one heck of a deal. This is sounding VERY promising I might just get this instead of a black box and just sell my Emanage blue.

 

When and where can I order one. Everyone's website says "Coming Soon". Also, will you have a wire harness for the 2007 Scion tC.

 

Dezod's got it on their site here:
http://www.dezod.com/pd_aem_fuel_ign...-universal.cfm
Listed at $409.

 

Will this unit allow for multiple maps with toggle switch for different circumstances?

 

Yes we will have some for the public in the next few weeks. We will be stocking and using these as the EMS on the kits if testing goes well. Stay tuned as we will have a full write-up on our opinions of the system.

 

Is testing already underway?
When do you plan to have the write-up done?

 

\

I get the unit on Monday

 

NUTS! I thought you had it already.
Oh well, I can still wait a couple weeks. I don't even have my turbo kit yet!

 

No, it only has 1 operating mode.

 

watching, as my Unichip and (piece of $hit) NEO are not getting me to where I want. 360 whp........

 

I guess this is a question for Delsolid or anyone that knows the true anser. Is the TC's ECU adaptive or not?

 

We just received the AEM FIC today!!!!
