Hondata

The no "down-p-i-p-e" option I was told by someone local that it was removed by Hondata a year ago.
All you have to do is to untick the P0402 sensor box.

Can Matt or someone at Hondata confirm please?

Forum won't allow me to type d-o-w-n-p-i-p-e. It changes the word to exhaust automatically.

Sorry, I meant no option for "exhaust". Not exhaust.

Update: I am able to successfully jaibreak the car now.

I am trying to select my mods on the tune. There is NO exhaust option to choose.

In older videos, there was a drop down for exhaust.

Please advise.

Thank you

Just got an email from Matt at Hondata saying they should have a fix in a software release by end of the week.

Thanks Matt.

Am i able to drive my car with a ... exhaust without issues until hondata resolves the jailbreak issue?


I have catted DP, frontpipe, and catback. I'm driving it. It is fine, but it just doesn't drive as it should without the tune. Stock ECU is likely limiting throttle, and retarding timing due ...

Hondata last week advised me to send in the ECU.

Now that Hondata is working on a fix, I will wait since the ECU is not bricked and car is running.

No, I tried it again yesterday with the car battery charging, at 13V and NOT using a USB hub, still same thing. Jailbreak failed.

I took a couple pics of the screen, but I have no way of attaching it here.

When I bought the instant jailbreak, I manually copied and pasted the VIN onto the field, but chose the option Used flashpro to copy in VIN, instead of the option I typed in VIN.

Also, as mentioned, I used a 2nd computer that was on VPN to purchase the instant jailbreak, as the tuning laptop wouldn ...

I just tried it again tonight.

The exact same thing happened. Says Jailbreak Failed. Dialog box only had retry button to press. After 5 times or so, can return to Hondata program and had to return ECU to stock.

This time I made sure my battery is charged. Connected to charger, Flashpro says ECU ...
