Its not to prevent overboosting. The ECM has enough injector control to fight off my FMU in boost and bring me back to 14.7ish. That is too lean. So if I am cruising on the highway and building boost but am hardly into the throttle it will be lean. If I stomp it and the ECm see WOT it diverts to open loop and lets my FMU do its job. I tried to divert TPS signal like we did on Pete's Wrangler and it worked for his but mine being an auto wants to downshift.
So I am going to try to use the hobb switch to switch the CTS out of warm range to drop it back into open loop.
Either that or I am building an AW4 shift box and eliminate the computer for shifting.
Ahh ok, so your going to use the hobb switch to look for boost, when it does it will override the cts to make the computer think open loop hence richening up the system? Smart thinking
Yes.
