Sorry if this question has been asked but I cannot find it on here or google.
Have the Tazer JL installed and I’ve been watching the boost readout.
Notice when in 4 lo it is not in boost until over 3000 rpm’s and even then it’s a very low psi. When cruising down the highway I at times see 10+ psi in 8th gear when at 2000 rpm’s prior to down shifting. In 2 hi it is in and out of boost all over the rpm range.
This makes me curious about how the turbo is controlled. Why is boost produced at different rpm level and how? Know it’s by the ECU but what is monitored to control the level of boost produced and when it is being produced? Seeing this I assume they are trying to keep out of boost while in 4 lo so when rock crawling there is not sudden power surges. Is this correct?
Will be interesting to see if the turbo boost does the same in 4 hi. Does anyone know?
