Hey guys I got a used Cobb ap for a deal I could not pass up recently and installed it yesterday and installed the stage 2+ map because my 05 5AT has motordyne 5/16 plenum spacer, k&n typhoon intake, Megan racing 2.5" res. test pipes, motordyne xyz with straight pipe module, and nismo s tune midpipe and muffler and I am running about 12.8-13.1 at idle and it dips down all the way to 10.8 at WOT which is way too rich in my opinion. Their tech support suggested that my MAF might need to be cleaned, but I do not think that is the problem. Would advancing my timing help lean it out to idle and cruise at ~14.7 and achieve somewhere between ~12.0-12.6 at wot? Thanks in advance for the replies and please done say get Osiris because I know it's a great product as well. Sorry for the long post.

What are you reading your AFR with?

the cobb has a real time afr display using stock o2s.

i would NOT increase timing past what is already done in the map on a stage 2 map w a cobb.. .. i threw a rod bearing shortly after doing so on mine.

try running stage 2 instead if youre running too rich.

i have catback, art pipes, and long tube intakes and im running lean on stage 2+

the map you have loaded assume you are making alot more power than your car actually is. You need to upload a lower level map.

ok thanks for your replies, im gonna load the stage 2 map and monitor the afr and see if that helps lean it out because its way too rich at the moment, guess thats better than running too lean though

i forgot to mention that premium gas where i live is 93 octane as opposed to 91 in other places so i wasnt sure if that has anything to do with it, any help is much appreciated, also should i should clean my maf sensor?

I think it wouldn't hurt to clean out the MAF, just as long as you're careful. At that point, if it's not the MAF, you can report back to tech support to mention it made no difference and see what they suggest from there.

Just checked mine. I'm at 14.7 @ idle w/ headers, intake, plenum spacer, resonated test pipes and exhaust on the 2+ map.

It's at 14.7 becasue it is being corrected. The ltft and stft are what is adjusting it.
