2nd 3rd and 4th?

Does your MAT flatten out or drop down quickly after that, or keep rising? Looks like it already got to 30 degrees above ambient.

that's showing 12.3:1 at 6100rpms in 4th.

13.49 is the PSI. Comon guy, these things are color-coded and labeled

datalogging is empowerment... and addictive
Is that 2nd, 3rd, 4th? trouble finding 3rd?
Explain the MAT? -0.30 max? - isn't that degrees C - as in a 64C peak?

yeah I'm all crazy and ****, i converted values so it was easier for us Americans to read.

Temp was 63-94°F
kPa was 188-195.
DC peaked at 86.5%

2nd to 3rd, was me deciding if I should take the corner coming up at full boost or not.....i decided to go for it.

I took a look at my IAT's monday. They are +40 over ambient, which I thought was horrific. What are others getting? Kinda a thread hijack...

The AFR and boost control plots look great though. Can't wait to see it saturday!

Tim you also have two small *** turbos driving the same amount of boost correct? is the compressor/turbine efficiency maxed? fwiw, i only saw a 10° delta at 7psi.

those air temps are not looking too bad for a smaller IC. I have a large FMIC and on the hwy in 4th and 5th under boost I see around 20-25 degrees above ambient.
