goin back to the base maps. just wanted to know if they are ne good?
buy initializing all data will bring me back to the base maps on the PFC?
the version i have is 5.08 hope this is the one that is tuned for intake, DP, HFC, CB and IC.

am i right ?

 

someone said up the % in the PIM and it will richen up the fuel for the desired rpm. but all the RPM's are maxed out at 100%. i am really tempted to run the base pfc maps. i need to know if its ok for my mods. someone please?

 

People seem to be getting several different "Base" maps these days. The one that shipped with my 5.08 PFC is a little different than the one shown here - http://www.exorzero.com/skotx/powerfc/ as Base Mod. Someone else recently mentioned having Base Mod fuel and Base Stock IGN. Also the "Base" map that came with my Datalogit was supposed to be Apexi's standard 5.08 "Base" map, and it also has very strange IGN settings. The "All Data Init" function will restore your PFC to whatever it came with, I suggest doing that, then checking it against the Base Mod map on the above link. If they match then you will be more than safe with it to run with your mods. I have the same minus the HFC but add the Efini Y-Pipe, huge FMIC, and RP fuel pump and I'm running way too rich. Hopefully a midpipe will get me into a more reasonable range to fine tune from.

 

I'm running the base "mod" map on my car. I don't have the FMIC or high-flow cat, but I do have a midpipe. However, I'm running at .89v @ WOT. This is at stock boost. My knock never gets higher than 60

 

does a higher volt on the o2 sensor mean richer or leaner?

 

Higher Volts = Richer A/F. This graph is from Autometer:



Obviously with the stock O2 sensor you can't rely on those numbers for safe tuning. But it is a fairly decent indicator of your ballpark.

 

so a higher 02 voltage is leaner? am i correct? at half throttle i was at 0.90 volts. guess im running lean. omg

 

No, look at the chart again, Volts on the left side, and A/F goes on the bottom. With a warmed up sensor 9.0 Volts is in the 11.5:1 range which is rich. Higher volts = richer A/F

 

ohh ok. scaried me for a second. thanks.

 

I just had mine dyno tuned at KDR and I have an M2 intake, medium IC, dp, and RB dual tip and I was a little on the lean side with the stock cat. With a midpipe you should be really lean on the stock maps, and running on a fine line of getting detonation.

Also with my setup at 12 psi, I was gettin 93% injector duty cycle when the temps are really hot. What is your inj. duty cycle at as well?

If you are running all that plus a mid pipe, have it tuned and get larger injectors or you will be getting a new motor soon.

 

i didnt do any WOT runs. all im doing is like half throttle. injector duty gets to 80%. im gonna wait till i tune it before i rip **** up. hehe

 

KDR's dyno back up???
I think you should be fine with the Base Mod map, check agains the other and add some fuel if needed. Do you have an EGT Gauge???

 

Can you guys post which version of the base map you're running.

when you start up the PFC it should display v5.07 for eg. the base map isn't a particular map it's just the map that was shipped with the comp from apexi. There are different versions of this "base map" so simply saying the A/F or timing was fine with the base map can be misleading.

When I start mine it says v5.08
