In a normal vehicle this would power the relay the whole time. We don't know how your vehicle is wired so if it works for you then great, but we can't advise on the wiring.

What vehicle do you have? What calibration does the FlashPro say your vehicle has?

Not that I know of. I don't check the xda forums every day, so if you see that people can root the 2018+ accord radio then let us know.

Yes, the procedure online above will work. Return to stock and unlock.

Find a diagram of the ECU pins. There are several vcc pins (vcc1, vcc2, vcc3) and several ground pins (sg1, sg2, sg3) to use.

You absolutely need to datalog the boost because otherwise you are at the mercy of every assumption you are making. Honda's claimed maximum boost is not accurate. Sometimes they list the maximum boost the vehicle will see under adverse conditions (high IAT, a lot of retard). For other vehicles the n...

Wire the MAP Vcc to one of the ECU VCC pins. With the MAP GND to one of the ECU SG pins. Wire the MAP signal to one of the KPro4 analog inputs.

The analog input conversion is
Conversion=Custom
Type=pressure
Unit=mbar
Voltage 0 value -45
Voltage 5 value 1790

Are you testing in a vehicle or just comparing the calibrations?

The calibrations were developed to give the noted change in boost. If you give examples with datalogs then we'll look at it.

Thanks. So it is a delayed tip in retard after shifting.

What KPro do you have?

Which of the two changes fixed it? Tip in or traction control?

What vehicle are you testing in? Can you provide datalogs?

There are multiple tables that limit the boost so we usually alter all but one in the stock equivalent otherwise people have trouble adjusting the boost. But if you give specific examples we can look at it.

You can ground the gauge to the master ground ie on the thermostat housing. You can use one of the ECU signal ground wires for the gauge analog ground. But do not use the ECU ground or ECU signal ground for the main gauge ground. The o2 current gives a massive current loop and causes problems. Witho...

Set the tip in trims by gear to all -100%. Zero out the traction control ignition retard ignition values.

I'm guessing it is knock retard from the way you are power shifting.

With the KPro4 you could use an analog input for the second MAP sensor. For the pinout see the factory manual. For the voltage conversion look at the settings in the MAP section of the calibration.
