Seems like it happens mostly in C mode. When I go to hit the gas it feels like its in too high of a gear and then goes and downshifts. I put on the exhaust today and I feel like it made it worse, feels like the car jerks. Anyone have any input or am I just going crazy lol.
Thanks

FYI if you can provide more details like what exhaust mods you did and if you have a tune or not or any other performance mods will help others chime in with their thoughts.

ECU hasn't adjusted? Maybe you need a tune or reflash?

tomespo

I was thinking ECU . It is a fluid motor union exhaust system deletes all cats and adds a resonator. Going to get tuned soon

Try the method to reset your TCU...maybe that'll help?

Well "C" mode starts off in 2nd gear i believe . Does it do it in "S"?

I always drove in "M"

I'm sure it's nothing crazy as the car only has 400 miles. What is the break in period for these cars? Also how do I reset the tcu?

obsidian05e55

Believe break in is 1000-1200 miles. Many argue about break in procedure, I personally drove my car like it was already broken in right out of the lot with 5 miles on it, and tuned it with about 1500. Only problem I ever had was Purge Valve, but that was a common issue on the earlier ones.

Don't think it was ever confirmed if they ECU/TCU reset trick worked on the newer cars.

1. Turn the igniiton key to the "on" position which is just before you crank the engine to start.

2. Press the accelerator to the floor and hold for 5 seconds.

3. Then turn the key to the off position but do not remove the key, then release the accelerator.

4. Wait at least 2 minutes, the ECU is then reset.

5. ECU is now reset and you are ready to get new rear tyres.

The ECU rest procedure only erases the adaptive transmission and throttle settings. It does not erase any of the fuel, timing or other programming.

I think you will need to be tuned to run completely catless. so that should solve your problems

Unhook battery and let it sit for about 15 minutes. Should reset your ecu and Tcm. Worked for me to remove thE jolts from tranny and better than doing Tcm reset alternative which I tried for weeks to reset. Adaptation is 1-2kmiles agreed.

Just like above....YOU NEED A TUNE with that set up.

Any exhaust work should get custom tune. Most people ran their cars like they stole it on day 1. Pulling strong!

I usually go for a drive in Mexico and do a few 5-150+ runs. The ECU adapts itself from granny mode.
