Really it's maddening with such a deterrent to quick changes. You can't just take the car to some quiet backroad for some methodical trial/error tuning. Every WUR change requires driving home, pull WUR while engine cools, then try again. On the Audi I could log a pull, add a degree of timing or fuel, log again, compare all the relevant vitals (absolute timing and correction factor, knock sensor activity, AFR, EGTs, and of course the all-important 60-90mph time) and know immediately whether I'm going in the right direction. Unfortunately since this was on cracked Motronic-7 there were limits, and anything that changed the VE of the motor was outside them.
