last night i tried to wire up my fic to my extension harness, took me a couple hours but when i got done i went to plug it in and the car starts, but it wont idle for sh*t, i have to bring the rpms up to like 2krpms or above in order for it to stay running. the VSA, engine light and airbag lights stay on, i ran my scanner but there were NO codes stores. freaking weird.

i connected the CAM and CRANK sensors using the HALL effect sensor diagram. i couldnt figure out if our sensors are MAG or HALL so i took a look at the sensors and they seem to be HALL style. i might be terribly wrong but i just cant find what type of sensors they are.

i also added the 1k 1/4w resistor for o2 sensor calibration. i used bank1 front sensor and bank2 front sensor.

other than that the rest was pretty self explanatory in the instructions (injectors, ground signals, power, etc)

now has any of you guys wired this up yourselves, or did everyone here get it done???

please help!

 

I found this out

im assuming it will also apply to the TL since we have the drive by wire setup in our cars

Re: FIC working with TSX or TL?

well first i got the patch harness for an RSX because of course no one wants to cut their wires then i got a wiring schematic for a TSX and the installation notes for an RSX and i matched my wires because the crank and cam trigger pinouts are different between the two cars also the wire for the TPS must stay disconnected because of the drive wire system of the TSX if that wire is connected the throttle will not work but leaving it disconnected wont harm anything and everything else is the same as the RSX just the cam and crank wire pinouts are in different locations so once you have those right you should be good to go but for every sensor you connect start the car in between each connection to make sure you have no problems.

paul can make you a harness, i believe his username is nva-av6.
i'm using one that he made on my TL

 

i have a harness, i just gotta connect the fic to the harness, but i cant get it right for some reason.

 

its hard to idle, and it wont go past 3k rpms. i checked all the wiring already and everything is ok... i found out that i was right by using the HALL wires for the crank and the cam signals. im gonna try to remove the resistors i added for the o2 sensor skewing and see what happens... oh n i gotta re-tap the TPS sensor as a member here has it tapped in in his setup.

You don't mention which year you have but the diagram could have some flaws in it. I made the modifications as I listed and the person I sold the harness and FIC to is having some issues with it. Not sure if it was my wiring mistake or if the wire swap between the 04/05 is different than my 06.

He has sent the harness to Paul to take a look at it but has not heard anything back as of yet.

Have you tried plugging in the harness with the jumpers in place instead of the FIC to see if it is the FIC or the harness?

 

my car is an 04 M/T, bought the harness n fic from HISPEED and he was running it for over a year in his 06 M/T. pretty much same deal as yours. but i rechecked all the schematics over n over again and it seems like the 04 & 06 m/t are the same. i didnt try using just the harness alone bcuz all the wires were split. the fic was not attached to the harness when i got it (obviously).

 

I don't think that is true as the ECU diagrams distinctly show a difference in injector and COP connections between the 04/05 and 06/07/08.

What I was referring to is a jumper that came with the FIC that connects to the ends that plugs into the FIC. It basically shorts everything back together so at least you can check if the harness is right except that your vtec solenoid won't be connected (takes the FIC out of the circuit).

 

when u sold your fic, was the harness attached to it? did u unplug it from your car and sent it to him but he couldnt get it to work? or was the fic not connected to the harness?

 

ohhh i see, i thought that jumper was to reset the fic to factory and i def dont wanna do that, i wanna use the maps that it has as a reference and tune from there. but i will try that next.

also ill be going to the library this afternoon and pull out the service manuals for the 04 and 06 and compare the pinouts from there.

 

NO! It is just a jumper that reconnects the intercept connections! Has nothing to do with resetting the FIC. You also realize that the tune is probably for his turbo with 410cc injectors.

These are the pages I am referring to.

 

yeah i know, but i have the exact same set up, same injectors, same everything, just a SC instead of the turbo. there should be no reason why i cannot idle. thanks for the diagrams i printed it out from your other thread already. ill take a look at them when i get home. i will keep everyone updated....

but you still havent answered one of my questions....

I have an 06-6MT, he has a 04-5AT.

I rewired it as noted in that other thread but there appeared to be something off. Don't recall exactly what his symptoms were. As I said, he sent it to Paul to see if I made a mistake and hasn't heard back.

I don't recall but I think the diagram from the other thread is for an Accord. The one above is definitely for the 04-06 TL. I doublechecked to make sure.

 

In the pinout you posted i only see 1 cam sensor listed in D7, do we only have one cam sensor instead of two?

 

04-05 ecu pinout and 06+ ecu pinout are very different when it comes to the AEM fic. I bought a harness for 04-05 to run in my 08 and I got the same problem as you, I rewired everything to fit the 06+ ecu and now it works perfectly, and do not use resistance for the O2 skew thing... I'm currently in the process of tuning the fic so I could help you if you have questions

 

well i did use my own schematics i had for my 04 m/t when i hooked up the wires.

but i solved the problem!!!

first i needed to create a new fuel map for the new injectors (rdx 410), set the redline, adjust max boost, etc (pretty much just follow the installation instructions), connected the fic to my laptop, loaded the new maps....

then....

i removed the resistors that the instruction told me to add at the o2 circuits and then tap into the wire. that took care of the codes i got for the o2 sensors bank1 n bank2

car still idle like shit n i wouldnt go past 3000rpms, i got a code, p0108? map sensor high INPUT, i spliced the wires and connected the map sensor without intecepting them through the fic. so pretty much i left the map sensor circuit as factory.

did the calibrations through the fic software, rpm and tps...

then the car started right up! no codes and running good

i took it around the block, im not sure if the vtec is activating but it pulls really nice now

hopefully i will have time to do some more calibrations and adjustments in between jobs.

but at the end of the day the car is running good.


p/s: for future reference we have HALL effect type CAM and CRK sensors. we only have one CAM sensor therefore we only use CAM1 wires from the fic

the CRK sensor must be intercepted through pin CRKA (crank position signal A)

 

i would love some help tuning the car!... lmk if you have any tips or whatever, 216-4 zero 2-6 zero zero 5

 

Nice, I am glad to see it's working out for you. Comptech set the VTEC at 4k with their supplied management, might be the sweet spot. I remember the car running really well above 4k with the SC.

 

That's interesting and good to know that you got it going.

What do you think was off, the maps or cals?

I emailed the person I sold my stuff to so he should hopefully check in here. Depending on where you live, maybe you could help each other out.

 

i think the most important thing to do is to leave the o2 circuit and the MAP circuit alone. DO NOT INTERCEPT IT WITH THE FIC!

after i fixed that it idle and run really good.

you also must load the base map into the fic n create the new maps, set ur specs (inj size, redline, max boost, etc) then calibrate the TPS sensor, then start the car and calibrate the rpms.

 

ok so i contacted tech support and they were able to help me with my issue

I ended up disconnecting all the wires and starting from scratch to isolate the problem with help from Pyng Thai at aempower.com

what worked for me was to connect the bare minimum. i got all the injectors connected, then I did the crank sensor and CAM sensor.

Adding the resistor to the o2 wiring was giving me a misfire so we went ahead and left that alone.
Same thing happened with the TPS and MAP sensor wiring. whenever i tapped either one of them I would get random misfires. so i bypassed them.

I adjusted the fuel maps and did a few calibrations and now the car is running GREAT!

im connecting my wideband o2 sensor today and getting it tuned soon! i cant wait

 

SWEET! Cant wait to see the numbers you put down!

You will need the MAP wire if you want to tune under boost. The MAP wire is not needed on NA car. And the MAP wire is not tapped but CUT. The TPS is tapped. like I said before the O2 wires for ''skew'' only works without resistors.
