Install resistors in series with the TBI injectors to "electrically look like" 4 port injectors.
I'm thinking with the cylinder select error disabled, the '427 memcal will still trigger the injectors every other DRP without causing "limp home".
I'm thinking the $8D injector flow setting will be very odd when firing the TBI injectors every other DRP, compared to a normal $8D injector flow setting firing the injectors every 4th DRP?
I'm thinking it would be better if the TBI injectors would alternate, but my O'scope video leads me to think both TBI injectors will trigger at the same time on every other DRP, but not alternate?
