Link shows a short capture of JB4 logs.

• Max "boost" hits 27.8
• Max "ecu_psi" hits 21.3

A google shows "boost" defined as:

Actual boost (psi) as measured in the chargepipe before the throttle body.

And "ecu_psi" as:

ECU_PSI is boost pressure (psi) as observed by the ECU. This is not the actual boost pressure, but rather the JB4 alters ecu_psi to control the throttle blade.

27.8 seems very high. Is this normal/safe to see it? It's very fun, but don't want to break anything.

Thanks

EDIT: ~1/2 the tank is 93 octane, the other 1/2 is 100 octane/Cam2.

can you do some longer WOT runs and post up. on map 6 i hit around 28-29 but that's my kill map

Do a proper log and send it to BMS for the best advice.

Thanks, I will do that. What's proper? Just a longer run?

I took a longer drive this time - https://datazap.me/u/admbe/log-16469...0&data=1-2-4-5

so you will need to floor it for a while. you will need to find a safe open road and just floor it to get some good log readings.

I floored it for as long as I could - our cars are fast haha. I got it up to the limiter.

I posted in the BMS forums. I'll update this thread if I learn anything for the curious or future googlers.

Thanks

3rd gear, traction completely off, floor it from 2500 RPM till redline

Thank you Mike. I'll do that next time I'm out.

Logs look fine to me but I'm no expert. Does not look bad at all. How does car feel on map 5 with that mix of fuel ? Any issues ?
Could probably use a little more 100 Octane added to the mix (+1gal)

Email Terry as well, he's cool and will let you know. Make sure you aren't getting throttle closures and dropping into map 0 he can tell you.
