So it is not possible to run above 14.7 AFR while cruising?

Hi there, I've attached a datalog using the provided calibration.
The vehicle behaved the same , you can watch the AFCMD initially target 15.3 and default back to 14.7 around the same amount of time post startup.

I have more information regarding this to elicit a response.
The ECU is a 37805-RL6-E540, with an attached calibration

I have posted two data logs, the first one is just a engine off to engine start datalog, you can at about 16 seconds the AFCMD switches from the value I have defined in the closed ...

This is on a 2009 CU2 using Flashpro manager 4.2.1.0.
In an attempt to salvage a little more fuel efficiency I set my Target Airfuel ratio to 15.3, and my closed loop Lamda target limit is an airfuel of 15.90, my closed loop target at low load is also 15.3.

Unfortunately our ecu don’t support it!


Did you ever find a workaround for this, or have you ended up settling for a manual boost control?
I've waited 6 weeks for my flashpro because they aren't stocked regularly in the UK just to browse through the calibration and see no boost control support ...

Are there any plans to add boost control to the CU2 ECU?
It's pretty disappointing to see that it isn't available while it is a functionality on the older CL9 ecu

Is no cu2 boost control a technical limitation or due to lack of demand?

Naturally, 5 minutes after posting this I see that the flashpro connector pushed out the white can wire. Pushed it back in and now it reads...

Hi, I've been reading these forums and seen this covered before but I'm wondering if I'm missing something.

So I have a 05 auto tsx and I'm intending on running flashpro, I bought the flashpro and the can adapter, and a 37820-RBB-A71 ECU from LKQ.

During the can adapter installation I ran into ...
