I have a FAST/Speed Pro ECU and its matching wide band o2 sensor. This is a batch fire strategy, but it can be updated by FAST for any option. Currently it is programmed for any GM HEI ignition and batch fire with the wide band option. It does not come with a harness, which can be purchased from FAST or from Fast Track Performance or I can supply the harness at a extra cost.

The cost to add any option, change ignition type ie; hei to opti or inductive and update the box firmware is approximately $50 by FAST.
