The car is highly modified and has a Harrop Hurricane ITB manifold. I have both B1825 and B1826 AC torque compensation set to zero however the car occasionally accelerates on its own with the AC on when starting off from a stop. Also again only with the AC on at idle if I rev the engine the throttle will stick at various RPM. On the road only with AC on under cruising conditions at 1800 RPM the throttle will hold at 1800 kind of like the cruise control is on. In all situations when the AC is switched off the problem immediately stops. I have also significantly reduced B2804 Throttle Open Rate Limits as shown below.

This seems to have helped the problem some along with the AC torques compensation, it used to accelerate out of control to the rev limiter and now it just accelerates a little bit or holds the RPM. Does anyone know if there is another table that is controlling the throttle when the AC is turned on? Also how far down can I go on the Throttle Open Rate Limits. I have been reducing down from 99.99 10 points at a time I am wondering if I can go negative. It seems that I may have already gone as far as it can go as the last couple of reductions seemed to have no noticeable difference.

Lastly this reduction in the Throttle Open Rate limits has made the cruise control almost usable. Before with the cruise on the car would buck and surge as the throttle adjustments made by the cruise were so large that it was unusable. Now it is just a little irritating. I plan to make some more dramatic reductions in the table to see if it gets better.
