Ive called 2 dealers. Both tell me that Mitsu will not update the ECU to the 2012 standard. I called Mitsu and they say to call the dealer...

Sometimes I feel I should have bought the Forester.

 

In for updates o nthis as well... I'd love to get mine tuned but its still brand new. I'd hate to start voiding warranties the day i drive it home from the dealership, lol...

 

If you just want fast throttle response/more aggressive gear shifts (or CVT ratio changes), you can most likely enable Ds mode. It works on the Lancer/Outlander, so it should work on the RVR.
The basic idea is that there is a hidden gate on the transmission lever called Ds, which is only available on Japanese models. You need to put in a button somewhere so that when you put the car in D, it goes into either D or Ds depending on the state a switch.
Basically, you need an on-on switch (see Switches) and cut the wires before they enter the ECU. This is right behind the button to disable traction control, which is a handy place to put a new switch.

Its easy enough to do on the Outlander 6 speed (pre-wired, and even in the service manual), but a bit trickier on CVT vehicles. The Russian Outlander forums have more info on it, I'm sure they have done it on an RVR as well:

Basically, you will intercept the wire going into the CVT ECU (C-130 connector) for D (pin 45, green) and make the switch provide power to pin 46 instead when it is on. You can see page 70 of the circuit diagrams in the service manual (GR0000040-90.pdf)

I verified its the same pinout for the ECU on the Outlander CVT and the RVR CVT ECU.

 

That sounds very cool. Thank you ivanz for the detailed info. This might come in handy if the dealer refuses to re-code my engine ECU.

 

According to Mitsubishis website the 2012 Outie Sport still only has 148HP. So what is so good about the reflash?

 

excellent question, haven't seen anything onliine really comparing the two, just independent reviews of each

 

Main diff is a recalibrated tranny. More aggressive throttle response. End result is lower mpgs of course! I have to say after 9k miles. I know how to drive the car well and make it do what I want. If I have to drive stupid ill sport shift it. Its lower power numbers make for an easier drive in snow and rain. I like it. I'm keeping the ecu stock.

 

I thought some of the users in the "won't start on first try" thread were reporting BETTER mpgs after the reflash?

 

That's strictly a rough idle/cam position sensor update. The 12 programming is a different animal completely.
