How we tuned cars before laptops...

[motorheadmike]

DBW cars can be pretty crazy. To calibrate the DBW throttle in my P71, with KOEO, you slowly depress the gas pedal then quickly release it, turn the key back to off, then repeat two more times. Anytime the battery is disconnected there is this complex relearn procedure you need to do. First let the car full warm up in idle, then put the parking brake on and let it warm idle for a minute, turn the A/C on and let it idle another minute, then release the parking brake and depress the brake pedal and put it in drive and hold it at idle for another minute, then drive 10 miles. DBW sure is better than drive by cable. 🙄
