safc2 settings with evo16g

[SpoolN]

I have a 95 Gsx Automatic, and just bought, Slowboy Fmic, 650 cc injectors, walbro fuel pump, safc2, wideband, and ipt upgraded tranny cooler. I was just wondering what some basic settings should be on the afc. I have the evo 16g turbo and plan on running around 19-22 psi. Just wondering what some basic afc settings should be also, does anyone have a map of the ecu where the wires for the afc will be soddered into. THanks

O2 dump is different from an external wastegate setup, O2 dump works with internal wastegate so no welding of flappers here.

Oh I didnt relize it was different so you still use the internal wastegate and run this 2. I take it by the barf symbol you dont like them? Howcome? reason i wanted to run this is becuase i get pretty bad boost creep at higher rpms

An o2 dump lets the exhaust gasses that pass through the Internal wastegate out into the atmosphere instead of being routed back into the Exhaust. This can be quite loud and isn't exactly legal...

A dumped O2 housing is the same as stock O2 housing except it dumps into the atmosphere instead of routing back to exhaust.

I don't like it because it's loud and annoying as well as drawing unwated attentions, I think it's a boarderline rice mod (remember the rule of no public flaming of a moderator ) not much different than venting your BOV. Most people either do it for the sound (I call noise ) and admit it, use boost creep as an excuse to vent or misled into believing it will solve boost creep.

The biggest cause of boost creep is the poor wastegate flow design of the mitsu housings specifically the wastegate entrance at the turbine housing inlet, the flow capacity of the O2 housing plays a small role. O2 dump alone can sometimes solve minor boost creeps but most of the time will require proper porting of the turbine housing, the key in solving boost creep, which then makes O2 dump unnecessary.
