Need new ECU, steps forward for tuning

My ECU randomly dropped out on me two weeks ago when driving. My RPMS dropped to 0, engine off, lights on dash, no DTC's because no connection to ECU. I got it diagnosed from a reputable shop and they informed me that I need a new ECU. They told me that they can't do Honda ECU's but that they would ...

Re: Severe throttle problem after installing FlashPro

I got it running good. Now I'm starting to adjust the WOT lambda adjustment to get a good afr. I'm just confused as to what all the other numbers mean on the PDF... I mean I get, for example, 43.5 psi you'd need to run a certain amount of opening time, but the psi ranges from 30-110. Is that just ...

Re: Severe throttle problem after installing FlashPro


Feel free to post issues with logs and I am happy to answer any questions.

Ok, I got some information from the manufacturer on injector opening time, but I still just don’t know how to tune it. Do I use these values on the fuel tables? Or just on the fuel tab in “injector opening time ...

Re: Severe throttle problem after installing FlashPro


Nice. Glad you figured it out. Make sure you have proper injector data before you start tuning.

I’ll try my best. Still learning so much with tuning… right now I’m just on a factory basemap with the injector size and rev hang changed. When going past ~50% throttle, I’ll occasionally get ...

Re: Severe throttle problem after installing FlashPro

Figured out I have aftermarket 550cc injectors already installed that I didn’t know about. Whenever I got my car tuned from the FlashPro, it apparently took off a previous tune for 550cc injectors. Had no idea. It’s back in running order now, ready to tune. The Honda dealer probably would’ve told me ...

Re: Severe throttle problem after installing FlashPro


If you have it all plugged in and go to the online menu and click on return to stock and it finishes doing that then it is stock.

I've definitely done that. At this point, it's not related to the FlashPro. Something must have happened at the very moment I installed the tune. I'm open to any ...

Re: Severe throttle problem after installing FlashPro


The FlashPro cannot damage anything like that. IF it returned to stock and has an issue then you should take it to the Honda dealer to have them look at it. Once it is returned to stock it is as it came from the factory.

Well, I don't want to point fingers, but this did happen after I started it ...

Re: Severe throttle problem after installing FlashPro


So if you return to stock from the online menu you still have a problem?


Yes, that's correct. I've tried it several different times, and at this point, I'm assuming it's not related to the FlashPro. Whenever I return to stock, I always check to see if I still have launch control, and it does ...

If you have any idea as to what I should do, please don't hesitate to tell me. This has completely handicapped my car, getting only ~10 MPG, and I don't know why. It's very infuriating.

Yes that’s correct.
Update: The throttle completely cutting out, having me towed, was a mistake on my part… tubing had come off while driving so I wasn’t getting a reading of any air, and never popped the hood to ...

Severe throttle problem after installing FlashPro

So I’m brand new to tuning and knew that the way to go was with Hondata. After receiving it, I went to Hondata’s help page and followed all the steps to installing the tuner. I picked a tune (stock tuned, 6000rpm launch limit) and began uploading the tune.

As soon as I started it up, I noticed a ...
