2016 Lancer ES Flat Spot

You said it happens 1/100 times and when you're slowing not stopped completely... being an auto, I'd be thinking it's probably coasting in 2nd or 3rd gear and the revs are too low for the gear you're in to give you the fast acceleration you're looking for. A manual box will solve this problem (where's rigby at? :p). Alternatively, when it does it have you tried pushing the accelerator harder to get it to drop back a gear, and does that make a difference?

Unless they have changed it in the CF, there is no gears with the CVT that would explain it trying to hold the wrong gear. Instead the ECUs should sense the increased throttle input and then adjust the engine RPM and transmission ratio to suit. When I drove a CVT CJ it was always a seamless process with no unreasonable level of lag accelerating from any situation.

2016 car has a upgraded CVT with 8 sport *poo* points as against 6 in all previous models. Wonder if this will prove to be a glitch in the new setup?
If so will be corrected.

The whole notion of shift points in a CVT is stupid. You could program an infinite number but at the end of the day it's better to just leave it in CVT mode and let the ECUs work out the most efficient combination for the engine and transmission. However, it does sound like Mitsubishi are using a different CVT unit and accompanying ECU in the CF, so it's possible there is a bug they haven't ironed out.

I'd be putting my money on either a dodgey sensor feeding into the ECU, an ECU glitch or a transmission issue as being the cause for the OPs dramas.

This would possibly have been placed in General or CJ column or CJ- CF column
or maybe new CF column.

I didn't realise that Mitsubishi classified the facelifted Lancer as a whole new model! I just assumed it was a MY16 CJ.

At the end of the day it's still fundamentally the same as the CJ, so no need for a new forum section. I have updated this section to be for CJ & CF.
 
Hi everyone just an update as i have been very patient at the moment waiting for an outcome to the flat spot issue.
From my last post i have logged all my driving (kms, distance,conditions) as advised and noted when the problem has occurred.
I am hoping next week i will be able to drive with the computer plugged into my car and when the problem occurs i can press a button and a snapshot will be taken a minute before and a minute after pressing the button. I will keep this post updated and again thanks for the input to my issue and again if anyone else has had this issue if i can please know the outcome.
Thx Eddie
 
Hi just updating been a bit of a long process but i think i will get some answers this week.
Mitsubishi has 3 data recordings from my car when it has faulted while i was driving it so will be updating what the outcome is hopefully soon.
I could only press the button once every time i recorded then had to take the car back to obtain the data and reset other values they wanted to test.
Thanks again and will keep you guys updated as a future reference
 
Here's an update:

Just got back into a 380 and it has the same "issue" you report. It is literally just that you're going at a rolling speed that can comfortably be held in 3rd, then you go to plant your foot and it's a weird grey zone where you were rolling fine, braking hard enough and then flooring it all within a short space of time. So the car thinks you're gonna keep rolling, you floor it and it goes oh *poo* shift down a gear without blowing up, oh *fudge* shift another gear cus powerrrr and that's your 2sec flat spot.

There's nothing wrong with your car, i have experienced it 2 or 3 timea so far. No biggie. Just gotta time your flat footing after a roll/ hard stop better or manually shift to 1st or 2nd when stopping.
