Misfiring w/ FIC
 

Recently bought an AEM FIC for my turbonetics setup. Took it into the tuner the other day to get tuned and Im having the mis-firing problem. At about 3k rpm its stuttering / jerking pretty hard. My tuner couldnt finish the tune because of this problem . So after doing some research, I found the "resistor fix". I did it, and its still doing the same thing. Looking at the forums on the aem site, I saw not only the Cam1MagI (+/-) but the CrankMagI (+/-) was done also with another 2k resistor. So I did that signal also and still pretty much the same. Its gotten a little bit better where its not jerking as hard but not tunable. Anyone know what else can be done?

check your slave version on you fic.........make sure your running z104.hex.......im pretty sure your running 1.07 or something like that.........

open up the fic program.....look up to the top menu......click file......click on "get slave version" follow the prompts carefully and tell me what you get........

I wish i could, but i cant check it out at the moment. I dont have that kind of usb cable handy and the jet game is about to start.

lol.......the cable should have come with the fic

I bought it used

ahh ic......well good luck with that

I bought my FIC in 07 and it used a regular USB. Did they change that?

Its a good ole usb type a->b cable available for $5-10 at any local bb, circuit city, or even walmart

I think your right...I need to find one for a friend of mine.........alot of people iv been talking to lately either got an fic used or just let their tuner keep the cable :doh: :doh:

ima go check at wally world......never hurts to have a spare too

Yes the original firmware of 104 is what will stop the misfiring.

Very good to know.

i had a missfire issue while the ecu was re learning with the tune. it cleared up after a tank of gas.

Crush / Paul .... you guys were right. I was running 1.07..... no good. Re-flashed the FIC with z104 and everything is working out. The tune will be finished tomorrow, and I should be good to go. Thanks for the help guys.


Im surprised this problem isnt a little more well documented..... on this site and the AEM site.

You're welcome.

your welcome.....it is however on the aem forums.....thats how i found out......lol

I know who you are talking about.. :rofl:

Yeah, I'll be headed up to Best Buy if Wally World doesn't have the cable.

lol yeah....i was planing to get an extra one anyways
