I did conversion from carburator to TBI some time ago. It´s working almost fine but now I´m trying a fine tune.
The problem is the idle BLM.
As much as I try to adjust the VE table, the BLM reading is always 123. The system goes in a closed loop and INT varies as expected. The reading of O2 swings from 50mv to 850mv. From the smell, it looks like the mixture is rich.
However, when I change to Drive or Reverse, the BLM goes to 128, at the same RPM. When I drive the BLM varies as expected.
I have already tried to increase the injector flow to force Lean and the BLM remains 123. If the INT varies accordingly why not the BLM?
My setup:
Engine 305 standard 50k miles
16197427-$0D BJWN bin mod to 700r4, no EGR, stoich 13.3
TunerProRT, A217 $0D TP5 v250.adx, Advanced $0D TP5 v251.xdf
Can anyone help me with any leads?
Thank you!
Marcus
