ZYA2 Idling issues under load

Unread post by bad86capri »

Ive finally been able to put some miles on the mach and noticed that the front end needs an alignment. The steering seems kind of tight to one side. The idling issue im having is when i come to a stop if the wheel is turned or im making a turn with the clutch pushed in itll put a load on the engine making the idle drop really low and sometimes causing the engine to stall. Is there something in the tune that can help correct this or bandaid it until i get the car aligned and the steering issue resolved?

set tc_under to 0 and use the fn85x functions to dump air

I could not find the FN85x function. I found FN851A and FN852A. Would it be the FN852A (anti stall) (proportional)?
