Hi Guys, is there somewhere in HP Tuners, were i can configure load to compensate for A/C on.
Engine Cadillac CTS-V LSA 6.2L, fitted with a Magnuson Heartbeat TVS2300 SC.
been working on the MAF and VE tunes, making progress, now pretty good fuel trims etc.
but one annoying bug to iron out, the engine stalling at lower speeds RPM's when the A/C clutch kicks in, have increased the idle RPM's and VSS RPM's which has helped quite a bit, calibrated the pulse to be within 1/2% of actual vehicle speed, which has improved things a lot. as that was far out before..
but as the ECM does not see the A/C system on, the idle up under load function is not available it seems.
any work arounds within the tune to me?
or should i be looking at installing some idle up bypass valve to increase airflow as soon as the A/C clutch kicks in?
any recommendations welcomed...
