Reduced power mode on Zs with eliminated secondaries
This popped into my head a while back about reduced power mode triggered by a trouble code. I don?t know the exact amount of codes that default our cars to ?normal? mode only. Even when the chip has been set to always have full power on all the time, this is overridden by a trouble code mandating reduced power.
What I am getting at is with a fully ported top end and eliminated butterflies, a reduced power scenario sees a lot air in the chamber and not enough fuel to burn with it in normal mode, creating a lean condition. I spoke with Marc about this a bit and he mentioned running an LT5 leaned out in this manner at WOT for less than ten seconds would not cause an issue. That was a bit of a relief. But then it had me wondering if any registry members with eliminated secondaries experienced this before.. If the engine reverts to 8 injectors because of a trouble code, if you keep the revs low, the engine should be fine as you limp it home. |
