2018 Accord Rev hang disable issue

Post by ajgarcia » Wed Feb 27, 2019 8:01 am

Has anyone else tried the Rev hang disable on the 10th gen Accord 1.5t?

I tried it out the other day and, with it disabled, the car wouldn't hold cruise speed. It would allow me to activate cruise and set a speed, it would also attempt to hold the speed but it felt like something was holding it back from actually keeping the set speed. Example, if I set it at 70, it would struggle to hold it around 65. But then, if you add a small input to the throttle pedal (1-5%), it would do it like there was no problem. Once I flashed it back to the base tune (I'm running stage 3), everything went back to normal. It almost felt like the throttle plate would close completely when you let off the pedal, even though the cruise was set, then the amount of fuel injected for the air charge was not enough to keep up.

Has anyone else experienced this? Is this a known issue with Hondata? I tried emailing someone at Hondata and have yet to receive a response

I have this issue on the 1.5T Civic Sport.

I have found that using the actual rev hang mod or checkbox will mess up cruise control pretty badly, but if you manually change the stock values down to the minimum (10) in all gears but keep overrun enabled, the rev hang is way better than stock, and cruise still is responsive.

Hope this helps.

I have forwarded this information to our software engineers.

Zac,

Not sure if the Civic calibrations allow changes in more parameters than the Accord ones. Do you mean you minimize the fuel overrun?

I'm pretty sure that checkbox for the Rev hang deals with the throttle plate overrun. I could be wrong though. I'll give it a shot with the fuel overrun numbers to make due, but would still like to hear something from Hondata about it



Spunkster, thank you for forwarding. Please keep us in the loop if possible.

Do you have hondata mode on your application using an econ button? If so, do you notice high boost levels in both settings? I am having this issue along with your issues on 2017 civic sport. Thanks

Yes, I have Hondata mode on but I only get the high boost map with econ turned off.

HMMM I just started my own thread on the issue I am having. Hopefully I'll figure something out. Thanks for the response
