    1, Goto Engine, Spark, Advance, Idle Adaptive Spark Control, Overspeed & Underspeed, P/N, Gear, & Coastdown. Enter ½ of highest RPM error constant value in first cell from 0. Interpolate from first entry to first constant value. Repeat for remaining tables.

    2. Goto Engine, Idle, RPM, Adaptive Idle Proportional Enable RPM Error.
    Subtract 10 from factory value.

    3. Goto idle Integral Enable RPM Error. Enter value 5 less than new Proportional value.

    4. Goto Proportional Airflow table. Multiply Normal values x 1.03.

    5. Goto Integral Airflow table. Multiply Normal values x 1.20.

    6. Goto Target Idle Speed table. Add 50 RPM to temperature stabilized idle speed cells. Copy same speeds into P/N cells.

    Not bad at the stop lights. It does shake a bit - enough to rock the car.

    Hmmm pretty cool

    I have played with the overspeed underspeed timing tables before to add in or subtract A LOT of timing below 75 rpm swings to do something similiar, but never on a stock cam.

    Problem is driveability usually suffers

    No driveability issues! Any throttle application removes the timing swings.

    How're you getting around that? Every now and then with a car that has a pretty aggressive spark correction setup has an issue.

    For instance, leaving a stop sign. Depending on where the spark control is at whenever you touch the gas, sometimes the car may leave at 18 degrees advance with the feeling of clean crisp throttle response. Other times it may leave at 6 degrees advance with the feeling of sluggish throttle response as it takes the ECM a bit to advance the timing back to cruise levels. Any help for that issue?

    I like to limit Throttle Area Rate Increase to 50% in gear 1 low RPM area. This also aids traction on A6 cars with that deep 1st gear.

    I would like to try this.

    Can you explain #1 a little more clearly please?

    For 4 and 5, I have several tables, adjust all of them?



    1, Goto Engine, Spark, Advance, Idle Adaptive Spark Control, Overspeed & Underspeed, P/N, Gear, & Coastdown. Enter ½ of highest RPM error constant value in first cell from 0. Interpolate from first entry to first constant value. Repeat for remaining tables.

    2. Goto Engine, Idle, RPM, Adaptive Idle Proportional Enable RPM Error.
    Subtract 10 from factory value.

    3. Goto idle Integral Enable RPM Error. Enter value 5 less than new Proportional value.

    4. Goto Proportional Airflow table. Multiply Normal values x 1.03.

    5. Goto Integral Airflow table. Multiply Normal values x 1.20.

    6. Goto Target Idle Speed table. Add 50 RPM to temperature stabilized idle speed cells. Copy same speeds into P/N cells.

    not maybe; it's definitely not going to be the same

    Step 4..... Multiply Normal values x 1.03 is that only positive values or both the negative and positive in those tables etc.

    Sorry to resurrect a dead posting, but I just came across this and think this would be pretty neat to mess with my friends. But as everyone was saying, can you clear up step one a little please?
