alright i'm about to install a z32 maf, 550cc injectors, and a boss tuned ecu in my s13 blacktop. obviously i'm going to do this in steps to make sure each component functions as it's supposed to. this would encompass (running car after each step):

1. installing z32 maf and setting sacf2 settings to 2-in 6-out.2. installing 550cc injectors and adjusting safc2 to -33% fuel correction.3. installing tuned ecu and adjusting safc2 to 0% fuel correction and modifying in/out settings.

here's my question. what in/out settings am i supposed to use with the tuned ecu installed? i assume that i wouldn't want to mess with the maf voltage since the ecu is tuned for a z32 input. therefore i would use a 2-in 2-out setting. is this correct?

If the ECU is tuned for Z32 Maf and 550cc injectors I imagine you can just use the SAFC to fine tune it... I wouldn't do that without being on a dyno though..

that's the idea...

i've been running on the 2in/2out setup for a few days now and it seems to have been the correct setting. hope this info helps someone in a similar situation.

does 2-in 2-out mean Disabled? 'cuz that's all i'd do with an afc.

If you installed everything and it runs, and you really want to try to get 20hp more out of it then bring it to the dyno and let them play with it with their wideband O2 sensor.
