Yes, it is an OBD I system and no, you cannot generally adjust timing. However, you CAN adjust timing with a DRB II diagnostic computer (scanner). Not to be confused with OBD II. 2 entirely different animals. I have one. I have advanced my timing 2 degrees from stock setting which is generally retarded 6 degrees by default.
Pics of the injectors I was speaking of earlier and a readout of the DRB scanner connected to my MPFI kit.
Also, as an alternative, because the DRB scanners are hard to come by, you can call Lee or Bernie at Hesco and they will burn you a Unichip to your needs with free tuning programs to download and program until it's fine tuned. They can change fuel and spark maps among other parameters.
