Actually, the timing retard feature is present on Volvo engines at least back to the B230F, which had a distributor. The secret is in that the ignition system has it's own computer on these cars, and on the Motronic enabled cars, the ignition and FI computers are the same. The computer knows what angle the crank is at, and knows what bounds it can fire in. The only Volvos I knew that had vacuum advance/retard were the PRV V6's before the B280.
