Hello Everyone!
I have the following issue with my car. I did pretty much the full nine-yards to my TA, and I've been working on my idle. I've gotten the idle pretty much down packed, idle transitions are great, AFR dialed in mostly (still working on the higher rpms in the VE table).
The only issue I'm having is a bogging problem that I have when I'm steering with no throttle and coasting while idling. I have a 25% UD pulley installed and I have a feeling that it might be part of the problem. Usually when this bogging happens the Battery Voltages will drop down to about 11.5-12 or so. If I'm coming to a stop and don't have to make any steering corrections because of the car pulling to the grooves in the road then it'll idle down great, once i need to make any steering adjustments it wants to stall out until i give it throttle until i'm stopped.
I have been working with TAQuickness on this and we've gotten it to a good point right now. We have adjusted the Engine speed compensation tables, leanred airflow parameters ect... to try and fix the bogging problem at no avail.
Does anybody have any suggestions on how to solve this? I know I could try and install a stock pulley, but I'd rather leave that for the last option possible. I've got the Powerbond 25% UD, so I'm wondering if I could install a overdrive pulley for the alternator, or a overdrive pulley for the powersteering pump if that exsists.
On another note, when logging at idle, and turning my steering wheel all the way over to one side, the engine will bog really low, and I will notice that my AFR will go so lean up to 21.00 for about 15-20 seconds until it'll suddenly come back up to normal rpm and AFR will be back even with the steering wheel still all the way over. So something is leaning it out and then correcting itself, which maybe part of the stalling problem.


Any Help would be appreciated!!
Thanks!
