Quick intro, I have an 03 Acura CLS 6 speed with the newest gen mp90 retro fitted to my motor. I am using the aem fic6. Everything funtion of the fic work great minus one map. The o2 map. I just replaced the primary o2 sensor with a brand new oem sensor, and still am not able to control my afr with the fic using the o2 skew feature. adjustments with the fuel map work fine, but not with the o2 map. when viewing the voltage via live data i can see that the secondary o2 sensor voltage change when changes are made in the fic accordingly, but not the primary. what is going on here??? if both are wired the exact way with the exact resistors (4 10k 1/8 watt), why am I not able to get the primary o2 to change voltage with the o2 map?! I am using map and offset as the mode for the o2 map. this is the only issue I am having and is hindering my ability to properly tune the car.

Here is a pic of my AEM FIC setup:

For those who have experience, please chime in.

 

You're not using a wideband? I thought you could use that to tie into the F/IC for O2 data/skewing.
How did you wire in the crank sensors for ignition or did you bypass them?

 

Is anyone even using the FIC without issues. Every thread i saw it mentioned it was about ppl not getting it to work right with our ecu. Sorry I am not more knowledgable to help you out.

 

x2. It's funny how some say you can use it and there are plenty of CL's running it but I've never seen anyone actually produce a dyno chart of a CL tuned on the FIC or report back that they've successfully tuned their car using the FIC on this board. Either way I'm eager to know if it's realistically possible.

 

I do have a wideband, but that is independent of the fic. our factory o2 sensors are narrowband. and you must use the primary o2 sensor to achieve proper long term fuel trims, other wise whatever changes you make using the fuel map will be overriden by the factory ecu via the long term fuel trims.

the crazy part is that i can control the secondary o2 sensor but not the primary even tho they are wired with the exact resistors?

anyone that can confirm for me what resistor values were used to get control over the o2 please chime in

contact Jproy. he will have answers

 

I have an FIC for sale, already wired for the CL. I couldn't find anybody who knew how to tune it, but I heard it can work. I had one guy tune it, but I honestly didn't feel a difference or see a difference in the wideband from tuned with the FIC or just off the adjusted FPR.

One thing is for sure, I had the car dynoed at 276ish hp untuned, then I had it tuned and it put out an amazing 300 HP with just 6 lbs of boost. The car felt like a rocketship! Unfortuneatly, the car's ECU messed everything up, and in 2 days (one drive cycle) I had a CEL with wacky Wideband numbers. The problem is that the J32 has 2 sensors, both have to be adjusted to accept the FIC tune.

 

Thats because everyone thats running it is over on V 6 P.

 

^^ u are correct sir . i say u guys should just wait for the aem ems 2 version that will work for cl-s. i know u are civicdrivr .

 

On a CL ECU or an Accord ECU?

 

Both, without issues.

 

James (jproy) is my friend, and his build is based off of mine.

 

I know of your situation, as Don from rpm systems built me a harness before you got yours. It was wired incorrectly, and the o2 emulator can not be used with our ecu. My motor subsequently blew because of that BS harness coupled with a bad tune. We ALL hear that "it works" on someones CL, but I am starting to think thats all BULLSH!T because nobody has invested as much time and money into a street driven CL as much as me, and till date can not find anybody to tune the car properly, nor have I discovered anybody who is doing any type of serious boost and it running with a piggy back or standalone 100%.

 

I'd like to see their maps and their wideband readouts at idle and WOT with no CELs. Have to see this to believe it.


PS I think Don is blowing smoke up everyones ass.

This is why I'm sticking with 6 lbs of boost and calling it a day. If I need any more power, I'll just have to get a different car.

 

Can you please direct me to the CL guys who are running FICs correctly so I may share information with them?

 

The problem isn't the hardware. Its Don. He doesnt know anything about tuning. Hes an idiot and a scam artist. Plain and simple.

Look at all the swaps his shop does, theyre hack jobs.

Head over to V 6 performance (dot) net

Without spaces obviously.

 

i thought you build seemed oddly familiar. how is jproy doing?

also, ive heard some baaaaad things about don.

 

I have posted on there aswell with no success. besides, the accord guys have a different setup as their o2 sensors are wideband, while ours are narrowband. unless you know of someone specific case you are referring to that will help me, can you please give me a direct link? thank you in advance.

 

he's doing alright, been busy with moving to new house and marriage.

 

i'll be running haltech. i'll report my results when available.

 

Talk to NVA-AV6 on here or V 6 P.

 

x2. So far I know of 3 who haven't been able to get it to work on a CL

 

I already have and got the run around with him

 

I think it's possible, but certain things need to be left alone, like the timing, since the ECU will make it's own adjustments. Just got to find someone who knows WTF they are doing.

Take it from me, the FIC will not work with out cars! I had 4 custom wire harnesses made from Don, Paul, and boomslang. Not one has worked, it was just not meant to be done.
