Terry,

Did you guys do anything to the traction control when on the dyno? I've had other cars on the rollers and we've always pulled a fuse or relay but not sure about this truck.

I want to do a before and after and just want to make sure I don't waste the shop's time while I'm there.

No issues with getting it on the dyno and turning off traction control.

sharing files~

hope we get some better number

I've got massive power gain on all maps !
what I found out that some car will show the power gain after 10-20KM odo riving, note that new ecu's will need some date feedback from the sensors to relearn.
In my personal car 2022 VXR it take around 10KM odo for adoption.

Question for you guys. Is the boost I'm seeing in the jb4 data logs the actual boost or what the truck thinks it's seeing?

Boost and boost 2 is what the car is making. Ecu PSI is what the car thinks it's at.

Have you guys been able to make any progress on incorporating some of these additional CANBus signals into the JB4 Tundra firmware? I was hoping to be able to put things like IAT and Trans Temp up on my gauges but they currently aren't captured by this firmware. Any thoughts?

I don't see why not, although our truck doesn't appear to have Sport+ mode as an option. If you have it drop me a JB4 log at idle with that mode selected, I'll see if we're reading it properly!

Terry .. I downloaded and flashed the beta FW to my JB4. I note that some more gauges are functional (yay!) and that the option of the drive mode switching shows up. I normally have Map 1 selected right now, and I enabled Bit 0 in options to attempt to do the drive mode map switching. For some reason, all drive modes (ECO, Normal, Sport) stay at Map 0. I've tried various times to switch maps in both Normal and Sport, and the app never shows the map different than 0. When I switch off Option Bit 0, I can see that Map 1 is selected for all 3 drive modes. With this being Beta, I don't expect a near term fix and perhaps I'm doing something wrong, but if I can provide anything like a log or what not, please let me know! Perhaps the app isn't showing up correctly?

You're the one who emailed me about this same issue right? We'll see what sorts of problem reports come in. It's a new feature so always possible its buggy.
