K20C2 Custom Tuning

[dt10g]

Does the throttle controller reduce the rev hang? It feels like the throttle is still closing when pedal goes all the way up from wot.

I don't think the Throttle Controller would relate to Rev Hang because...

http://www.ktuner.com/KTunerHelp/disable_rev_hang.htm

"After the throttle has been released completely the throttle plate is commanded to stay open a nominal percentage and slowly come back down to a point where idle control takes over. The blue arrows (see diagram..)"

I will try and do some videos over the weekend regarding the evcX , and maybe I can also do something for Rev Hang on/off and perhaps even play with the KTuner throttle response options...

I'm kind of curious how the operation of the KTuner throttle setting compares to the evcX, and if using both in conjunction could be useful in some way.

The selection for rev hang is disabled on ktuner for the c2

I guarantee the Rev Hang OPTION is available for the C2 from KTuner,
see below

it has been available for some time I believe, but this is the latest version:
whether it has an AFFECT one could debate...

Just to be clear, I CAN click that box and save tunes with Disable Rev Hang

I cannot say whether the tune for K20C2 *CVT* models is the same or not... maybe someone else.

It might be because of my ecu part number/version. I’ll have to check again

What’s your ecu code when you pull up the base map? Mine is 5bb-a1x mt, I’m not seeing the quick enables.

For brakes, you can do oem si calipers, rotors, and pads. I did it to mine and got great braking now. I did full upgrade including the rotor shields (had to replace front wheel bearings)

Can I upgrade to Si brake rotors without changing dust shield size?

Yes I was just reading up, and for sure may depend on which ECU you have

I have
37820-5BA-C14

I believe in that suffix that C is Canada, and A is America...

FWIW my car is a very early build...
it is a 2016 produced iirc Oct/Nov 2015 and my VIN ends in the 005XXX

There was also some discussion under post 5 here about this kind of thing,
but didn't give any indication about which ECU have it and which do not
#5

My post at the time showed what I was seeing in Ktuner if that helps
#9

I read over on the KTuner Forum (under 2.0L) that there were at least some versions where they indicated they had perhaps received negative feedback and pulled RevHang from the option. It would be great to get a list of ECU vs. Support from them, particularly if one was on the fence about buying one or not.

You’ll have to bend them back. Looks cheap.
