It is also good to do a search from Google. For this site search in Google you'd type: fitfreak.net: 6MT low rpm stumble

 

i have to add to this , i have a short ram intake and a medallian axle back on my '19 , last year in had a larger b pipe on the car for a few months
( went back to stock set-up , was too loud , took my mileage down ) anyway , with the larger pipe the car never stumbled . also , this week i went
with a set of 195 55/15s . i think the slightly smaller diameter puts the car in that sweet spot on throttle tip in , feels way less finicky

 

+1

light weight wheels, 195 (lighter) tires, modded oem intake, bisi exhaust, and ktuner = no stumble for me.

 

If we change the diameter of the tire - is there an adjustment in the 'puter that needs to be made to calculate odometer and other wheel spin calcs?

 

Has anyone determined a true fix since this thread was last posted to?

 

IIRC, it's an issue associated with the stock plugs on the GK5.
I've been meaning to replace mine, but just haven't gotten around to it.
Besides, it doesn't seem to affect any other aspect of the car in regards to maintenance etc..

 

FWIW, I have a 2018 EX and noticed the same thing, but it reminded me of the B-Series engines from older Integras.

I recently purchased the Pedal Commander, and though there are mixed feelings on it, I’m very happy with the results. I drive in City Mode +2 every day and the Fit is not “faster” but it is “quicker” if that makes sense.

I’ll look to do a video this weekend. Hope that helps.
