Also keep in mind if you solve the issue of running a LT5 with a LSx PCM. you also need to make the CCM happy
There are only 8 injector drivers. Remember the LT5 code is a derivative of the L98. GM didn't move on to the 2nd Gen LT-5 because of the need to develop and certify a new ECM and code.
The firing for the secondaries is piggybacked from the primaries with the power for the secondaries provided thru the secondary relays. The secondaries shut off at 0 throttle and use the VE Port Closed tables at that point. You can see that in a data log with the ECM switching from Port Open to Port Closed.
By the way that goes for the SA tables as well. And then there is the question of the CCM.
