Hondata

All was fine with this P28 / S300v2 for years now. This morning the car was running, working fine. I moved the slider bar in S300, the car died.
Upon trying to start I have a electronic boost solenoid going crazy and SManager showing me this with ACC on. Can't upload, and no parameters available. Is this hardware or software?

More info:

- version of software being used (Help, About)
-- 2.7.6.0

- the calibration (as an attachment)
-- can't load it

- a datalog of a problem (as an attachment)
-- N/A

- what sort of vehicle you have
-- 1993 honda accord w/ H22A

- what sort of ECU you are using
-- P28 ECU w/ S300 V2 ECU with PWM boost control

Did find this post which is close to mine.... , seems the best bet is to try another ECU (which is impossible without purchasing one).

I also found it weird that as soon as I move the slider bar for IACV in SManager the car responds immediately without using the upload button. Live feed option?

After re-seating the S300 module etc, this is what I get...... so hopefully it's just the S300 portion and not the ECU. Not sure.

Do you have your calibration saved on the laptop?

Yep. Tried new calibration and clean installs.

Is J12 cut on the ECU?

With everything plugged in and the ignition in the on position, go to the Help menu and click on “send feedback”. Include a detailed description of the issue.

J12 is cut on the ECU. and submitted.
