Maft idle help!

[Tofuboi]

I've just installed my 3" gm maf & translator today with the Dejoin UICP, and my car wouldn't Idle. My car is bone stock, so I've set aux=4 and base=2 for 450cc injectors. When I start the car it would stutter and die off, so I've adjusted the Idle=5 to get it running right. Mid/WOT=0, and when I drive off idle it's still running very lean, and starts bogging around 3500. I've tried adjusting mid a few clicks but the car still will not go stoich/rich .... everything stays lean. My palm has been misplaced so I'm not even sure where to start.

Make sure that all your wiring connections are secure at the connector. If you are pegged lean, I would suspect that the airflow reading is not making it to the ECU.

Another thing to look out for is to make sure you mounted the GMAF in the correct airflow direction. Just trying to give you ideas, but it's hard when the car is not in front of me.

all the connectors are connected properly. idle seems good, but when driving from 1000rpm-4000rpm is it still pegged lean, anything after is okay, from stoich to rich.

my setting right now is

Aux = 3
Base = 2
Idle = 5
Mid = 4
wot = 2

this seems really high to me?????
