A/F Question

[hmo124]

I know this is homemadeturbo, but i figure i might get some feeback. JRSC 6psi b18c JDM GSR a/f reads between 12.5-12.9 under wot. Never see 13.0 or higher underboost. Basemap is from xenocron(sorry if i spelled it wrong) Heres a vid of the plugs after a few pulls Any info would be great JRSC+spark+plugs+after+few+pulls

there might be a little detonation there, I usually see the heat on the ground strap go down a little further but what you have should work, What are you using for WB?

[hmo124]

well i didn't think it went into the 13's under boost but i guess i was wrong

Idle seems weird also
the longer it sets the richer it gets? then again o2 sensor is disabled, does that have anything to do with it?
Sorry guys but as you can see i'm new and learning at this stuff so anything info would be great.

The o2 sensor would have a big deal with it because it regulates what air is flowing through the exhaust, and it will tell the car wheter it is running rich or lean to a certain extent, you might want to take care of that, or you could just use a piggy back or standalone unit to regulate the a/f ratio. Regardless if your plugs are white that means you are running lean and most likely have a good amount of detonation, carbon deposits and blackness means that you are running rich, always tune a little rich if you can tune for a street tune because if you go to lean for too long you will have major problems.

hes running a basemap on his chipped computer. he has the 02 sensor disabled in the tuning program. technically it is a standalone system. he just needs his ---- tuned is all basemaps work for some and not so much for others

[RyAn007]

Oh, I completely missed the part where you had a chipped ecu, sounds like you might need a little fine tuning than.

[Scott-EP]

Basemaps are only for you to drive to a dyno or tuner. They aren't for daily driving or street racing. Get your ---- tuned and be done with it.

[hmo124]

I agree basemaps are only get you to the tuner, that is unless you have all the tuning sorftware/wideband.
Well heres a short vid, at least i got it off 13.2 in boost.

Alittle more tuning, right about where i want to be
Wideband%2fcrome+tuning+2

vids suck i know.
Seems like tuning isn't so hard if you have the right tools/software.
I'm just starting to learn this stuff, not used to looking a maps/wideband but you quickly learn .
Now i guess all i need to tune is part throttle. any tips/advice?
