a6 block / z6 head more fuel for boost?
 

Hey i was just wondering but if i do -40% on the AFC hack at idle, the idle is complete ----.. it goes down to about 400 rpms and just shakes the car like crazy... seems to hold the rpms evenly at -38% tho, i was just wondering since i have a higher CR would that need more fuel or whats the reason behind it runs like complete ass at -40%? j/w.

Very possible..

what injectors do you have?

Re:a6 block / z6 head more fuel for boost?
 

thy 450cc injectors

so my little theory is correct?

also on my PM6 ecu and 88-91 civic/crx si wire harness.. what wire do i connect to the A/F gauge (yes its a shitty reading but better than nothing like i am right now) i have my A/F gauge hooked straight to my 1 wire o2 sensor and it never reads anything but the farthest rich line...... no matter what.. even when i lean out the fuel so the car almost dies... i'm thinking of connecting it to the wire that goes into the ECU from the o2 sensor wire.. what do you guys thinks???

Pin C15.. it's a solid white wire.

Re:a6 block / z6 head more fuel for boost?
 

my helms shows C16 as the o2 sensor....... haven't looked on the wire harness yet to see if it is a solid white wire tho.

On my hotrod C15 is the MAP and it's blue with a green stripe. C16 is the 02 and it's blue with a yellow stripe. ???
