^^ How To: AEM F/IC-6 Install, Tuning, and Help Thread

I am curious about this resistor deal. If I don't get any codes, does that mean the signal to my piggyback is probably ok? Or would a resistor help smooth things out? I do not have the AEM unit but I'm thinking maybe a resistor would help smooth the signal to my URD unit and help make the timing tune more effective? Or does this not make sense? lol

 

Resister just cleans up the signal for the ECU. If you run the AME FIC without one, you may through an engine code. Gadget is right in saying the MAP ECU plays better than the AEM FIC but a simple resistor fixes that so not really an issue IMO.

 

Yes but I haven't posted them here if you go over to T4R.org you can check them out

 

Just updated the install instructions my previous Pinout chart was Fubar for the cam/crk signals. All fixed!

 

How are you tuning? I have an OBDII connecter but haven't found a decent/affordable software to monitor and map engine parameters. Im still not sure if Im going to try to tune myself or get someone to dyno tune.

 

Bump!

I ordered the AEM FIC, hope to install and tune this spring before wheeling season gets going.

 

Let me get this updated then! I havent been updating Tacoma world thread

 

BUMP!

I got mine installed and running with no issues. I just need to find some time to start road tuning.

 

How is the AEM fic working for you guys? Im contemplating ordering this to setup a S/C on my 99 manual Tacoma.
Tim, how has the tuning been coming?

 

It's coming along. I just need to fine tune my O2 map to screw it when I'm at higher elevation as the absolute psi the FIC sees is lower than the psi I see on the Guage. So when I'm pulling hills at 65 it's a little leaner than I like to see.

Definitely way better than the split second unit.

 

I didn't see anything in the list for an 04 Tacoma 3.4 like mine. It only went to a 2002.

 

Would this unit work on a turbo?

Is there any tuning unit that I could use to make the stock engine quicker? Maybe with different timing?

 

It's will work just fine, you might have to wire it in instead of a boomslang harness.

Turbo yes

Stock probably not much. The FIC only takes out timing.

 

Been rocking mine for years, just went off-roading with the T4R guys (see wheeler anonymous thread) in big bear. I don't go into boost much at all at sea level and wheeling, but up in the thin air, I notice it wanting to boost to move out of it's own way.

I'm actually sitting on the parts to move over to an EMU setup, I just like the EMU more so finally broke down and get a split second part to handle the closed loop o2 signal. IMO the EMU will fix the cam/crank signal issues the FIC has, and I get ping when my auto tranny shifts (OEM ECU advances timing when shifting). The FIC has timing retard just in mapping like for fuel, but the EMU has an additional tranny shifting timing retard feature I hope will dial this away.

 

Anyone still around from this topic? I'm looking at the diagram for the 2.2k resistor and it does not match the description which says to put the resistor between the CAM MAGO - and the CAM MAGI +.

The diagram shows the resistor between cam magi -, crk magi - and the cam mago + which seems kind of ludicrous to me. I'm assuming the description above is accurate? Also, has anyone actually done the described method and can report it actually works? Seems strange to have the resistor in parallel with the fic. A bit rusty on circuits but isn't that sending both the modified and un-altered signals to the pcm? Would it not be better to use a much smaller resistor in series with the fic and pcm?

 

I did as you described, - to + on the mag circuit. I too thought it was wrong but have had zero issues since installing the fic.

 

Thanks for the quick response! I also noticed the typical scheme of using "I" or in wires to recieve the signal at the FIC and "O" or out wires to send the altered signal to the pcm but with the injector wires its backwards from that in the AEM directions. Did you follow their directions of this step and did it work ok?

 

I did, I got the first couple of injector wires wrong but looked at the wiring diagram and corrected my mistakes. Take your time and it will all work out. What year truck do you have? My 01 didn't need the O2 resistor just some time in road tuning.

 

2000. Is yours narrow or wideband? I have 2 narrow band sensors and I'm a bit hung up on how to wire them. I'm assuming the second needs to read something different than the first or it will throw a code so I can't feed the fic's altered signal to both pcm inputs but if I just leave the second sensor alone it's readings will be wildly off from the altered first sensors and may throw a code as well.

 

my 01 is a wideband so i didn't need the resistor on the O2. You are only working with the front O2 to tune the truck, the rear is just a tattle tale that your cats are working properly. You will need an aftermarket wideband O2 to tune your truck properly.
