Hondata

Coil packs, sparkplugs, and maf sensor were replaced, car still misfires in boost. Runs perfectly fine out of boost. Stock tune, basemap, it makes no difference. I’ve checked for vacuum leaks. I’m at a loss, if anyone has any information at all it would be greatly appreciated.

On my drive to work this morning the car was missing horribly, finally threw another cel. The misfire moved to cylinder 3, following the coil pack that was originally on cylinder 2. Going to pick up a new one this evening and see if that solves the issue. I appreciate all the help

I replaced the PRL intake with the stock intake, and flashed the ecu back to stock. Car still has a misfire. I attached the datalog from the stock tune. It seems the car is still lean into boost. Any ideas what could be causing this? Seeming to be not tune related since it’s doing it in its stock ...

I’ve inspected all couplings, and the maf housing itself, nothing seems out of the ordinary, how would I go about compensating for the HVI misreading?

So essentially you’re saying there’s a potential boost leak, and the car is trying to correct the fuel trims to compensate? Could this be something tune related? I have the PRL HVI with the big bore maf housing.

Could this be signs of the pump failing? Commanded pressure is 2900 but it only sees 2870~ most of the time.

Any ideas on how to correct?

Attached is my datalog. Car misfires when you first start driving after warming up, and when you get into boost. Sometimes it’s perfectly fine. PRL HVI, PRL IC and Charge pipes, Hondata basemap. Everything else is stock besides a muffler delete. And help would be appreciated!
Edit: car is on the ...

Factory reset the head unit, re- hondahack’d it, and installed the newest version of the hondata dash apk v1.6.0. Same error.

Any suggestions on how to proceed? Thinking of factory resetting the headunit this evening

Yes, I purchased the app this morning to test it, and it connected immediately and automatically

It is enabled, I’ve done the unplug, plug, unplug. Multiple times, tried with that mode on, tried with it off. I’m at a loss. Is there anyway to confirm the flashpro is using the alternate pairing mode?

Actually have the same exact issue in my 18 type r. Same thing when attempting to pair the flashpro via the car’s Bluetooth settings. Random code that requires action on your phone(flashpro). But the flashpro has no way of interacting, it times out, and fails.
