2011s will work. Thats what I ended up doing is turned off the O2, set the Closed loop LTFT threshold down to 50hz.

 

First one that seemed to do this. The stock injector cars are all stock turbo as well so I doubt I would see it this aggressively.

 

Note the timing dip of 2* that happened at 5000-5500 without knock or load varying.

 

So did that fix it?

PM me your shipping address. You'll get a box from SpeedCircuit.

 

It did fix it but its something I havent had to do on the other years to make the tune work. 2008-2011 havent been like this for sure. Especially with signs of the TB closing on me in one or 2 of the pulls.

Well someone decided to run off with my trailer apparently. I'm going to look at a replacement today and I can bring you the 2012 as promised.

 

Dude, way lame

Let me know when it will be here and we'll get right on it. I am going to start by baselining your car and then we'll go about the plan as discussed.

Yah that sucks. Hopefully it was insured

 

No Bueno

 

After following this thread, it makes me glad I bought a 2011 instead of a 2012. I just wonder why Mitsubishi would change things when the run of Evo's will soon come to an end in 2013? It would almost appear that they were trying to reduce emissions and possibly increase fuel economy ever so slightly.

 

It's difficult to say. Who knows what's going on in 's head. They may have some secret initiative for racers that we just haven't tapped into yet. They may be trying to make something work for regulations. They may just be complete jerks to screw with us . Whatever the reason, we'll find a solution eventually

 

I've been getting my '12 up to par and I have the same issue at 5000-5300. I look at the logs/files and there's nothing that's out of place or not smoothed at all. Very confused as to what's going on and why it's happening. I do have knock (1-2 sum count) which is enough to start lowering the timing a few degrees at those RPM's. I will not have knock anywhere else, except for those rpm's. Weird. This is only running 22psi with everything stock, except an air intake and IC plumbing.

 

You are right Migs. I take my hat off to John Bradley for his amazing sleuthing and investigation of this problem. I am sure that he will get this totally figured out and get any 2012's he tunes back up to snuff. The TB closing reminds me of what Honda had done to the K20Z3 engine in the Civic Si. Doug MacMillan of Hondata noted that the TB closing was done for emissions' purposes, which made drivability horrible. FlashPro fixed that.

 

They wont take a dump without a plan. This is based on 2 or 3 things like it has been since 1990 with the 1GA Eclipse.

1- Make the car/engine/etc last 100,000 miles for a warranty they deny anyway.

2- Make the trans last for a warranty they deny anyway

3- Make the engine maintain a decent level of performance but focus on emissions first and foremost then mileage, lastly add horsepower.

#3 is why the exhaust port and valve is so small. Light the cat off quick by making it run WAY HOT and dont worry about the long term effects of EGT. 2012 is the way it is because they have watched us with this car for the last 4 years and know what we can already do. For them it was a quick software change and then its finito.

What we really need is a universal ROM for all years like the VIII has. None of the other parts have changed (least by PN) so if we can control it exactly the same then we can remove the last part of the puzzle.

p.s. They all need standalones anyway, GawDang torque management is for the birds...chirp chirp.

 

so... if I'm reading this correctly (and understanding it too)

Anything that isn't precisely tuned to work around these issues like mods with no tunes etc. will make the car go boom?

All in the name of a smaller carbon footprint?
