Moisture or vibration.

Your above post is against the rules I posted, as well as some of your prior posts. Please either stop using the forum to solicit business or post the resulting calibrations.

VTP is not needed for VTEC. Disable VTP and multiplexor. Ground VTP to activate the AC compressor output.

The RSX/DC5 ECU does not have DBW. It only will work with a cable throttle.

You're trying to use one FlashPro for two vehicles. Lock it to one vehicle and don't unlock it.

It should unlock now.

A stock like calibration is not going to help. Where are you, what sort of gas and what modifications? I think that you need to address the AFM reading first until the short term trim is close to 0%. Once you have done that I believe that you should be able to switch between fuels and let the knock ...

The ECU is in recovery mode so it is working. Battery voltage is as low as 8.6V.

What you need to do is put a battery charger on the vehicle and keep uploading until it comes out of recovery mode.

I'd still like to know why the ECU was opened.

Please use the 'send feedback to Hondata' function with the FlashPro plugged in and the ignition on. If you reverse polarize the ECU it has a zener diode to pop an external fuse. Nothing bad happens to it. What I really wanted was the story from the start, since you have posted about the same proble...

Thanks for the feedback. Glad to hear that everything is good.

You would need to send us the ECU and FlashPro for unlock.

How did your ECU get damaged? What's the full story?

O2 sensor and heater errors do not cause the ECU to go into limp mode.

Please post your calibration and a datalog.

I've tested and confirmed that it is working with 2.7.5

Question: Is this in a running vehicle? Do you have good fuel flow through the sensor without bubbles?

Do you have the AFM connected and reading correctly? Is is the stock MAP sensor? If the vehicle turbocharged?
