sorry to say this but your probably not going to find anyone tuning N/A on a FIC. reason being is you cant advance timing on it only adjust the fuel the ratios. the FIC was built mainly for boosted applications.

just curious to know, how are you advancing timing? even AEM states that the current FIC software only allows for retarding timing. i have the FIC, but haven't installed it yet. if it can advance timing, that would be awesome!

... yeah oook nice try to cover your butt lol no dice though.. just busting

anyways the thing is without the ability to adjust timing on a bolt on tc you wont see much improvement, a few hp at most. the only way i can see the FIC helping N/A is if you had to adjust for large air ratio changes like the following... more aggressive cam profile, high flow intake manifold, ported head. but then you still cant advance timing so you still wont get the most out of it that you could if you were able to.

long story short is that FIC is a waste of money on a N/A tC. the stock ECU is actually pretty good at adjusting for bolt ons. however when going all out there are better options out there for that.

its made for F/I not N/A sorry to rain on your parade

you won't gain a lot peak but usable power you can depending on mods and the piggyback unfortunately the AEM FIC is not the way to go. On my I/H/E with the AEM EMS I gained a lot useable power at one point 10hp and 5 ft lbs at the wheels but not much peak. For n/a the oem ecu does a fairly decent job so personally if you are looking for more punch go boost!

the unichip i've heard is designed for N/A, can it advance timing? if so that would be a better piggyback for you

Sorry forgot to mention if you can find a piggyback that can adjust fuel, timing, and vvti this would be ideal but I think most will only adjust fuel and timing and there are a few just for vvti.

I need the f/ic for my nitrous i dont care about a high performance tune for me N/A I justt need a fuel and MAF map that will give me a stable A/F at WOT when daily NA driving since the 0ed out map runs fine but has a really wild A?F flux

^ then why did you post it as AEM F/IC N/A tune? you should have put it up in the FI section and specified nitrous

Im not looking for a nitrous tune, I have one it works great. it is a dual calibration tune, the other tune connected with it is just a zeroed out map supposed to act like stock but my A/F dances all over the place on the zeroed out map nothing to do with nitrous i just need a NA fuel and MAF map to dial in my WOT a/f so i get less bogging in my shifts

if you have the PnP harness you could just unplug the unit when not using nitrous. ether that or your gonna need a separate tune for daily driving. i don't think zeroing out everything is gonna work.

if you have a wideband and data logger you can drive around and record what the a/f is running. you will be able to see if its to lean or rich and adjust it accordingly on the fuel map. it would be a rough tune but it be better then nothing.

zeroed out works fine other than the A/F acting a bit weird its not really a huge problem I was just wondering if anyone has a NA fuel map even for an EMS that I could see and just have some guidelines
