Roo Systems Ecu Remap
 
http://www2.pajeroclub.com.au/forum/...pictureid=4330


Recently had Roosystems do a Ecu Remap on our Mitsubishi 2012 Manual Challenger ... went with the touring tune ... asked for better pick up down in the lower rev range and better fuel economy :) only modification I have done is a straight through muffler. Still running standard H/T 265 65 R17 tyres.

Well have to say I am over the moon with the results :)
Just did a return trip to Warwick QLD from Gold Coast ...
- Load : 3 Adults 1 child and all the gear for the day
- 8.6L/100km on the way up
- not measured on the way back, but did a fill before returning &
used less then a quarter of a tank (probably mostly down hill :) ).

Now pretty much drive with only about a quarter throttle,
between 2000RPM-3000RPM, all the torque is there no need to over rev.

They also mentioned it will help with sand/beach driving, in theory by looking
at the dyno chart this does make sense.

Will keep monitoring ;)

Am i reading that right that the torque at 1,500rpm pretty much doubled from 150Nm to 300Nm?

certainly looks that way ... and yes can really feel the difference ... :D

If that's accurate that's an insane gain.
Looks like it's showing the standard torque peaked at around 330Nm. Do you have an auto? That would account for 50Nm straight away.

Manual
dyno runs done in 4th gear
Max torque approx 395nm at the wheels.

figures shown by mitsubishi are at the flywheel (as with most manufacturers).
power lose from the drive line is approx. 15-20%

:D

Nice gains pre 2200rpm!

So much for the engine having a laggy turbo.

that's what I could never get my head around ... especially being a variable geometry turbo ... :dunno[1]:

in saying that I still have a little lag ... but less noticeable ... possibly going a bigger exhaust could help it even more ... for me it's more then enough improvement and money well spent.

im thinking of getting a 3" exhaust then getting a chip or a remap.
so u still have standard exhaust?? except straight through muffler?
do you have a egt probe?

Roosystems it worked for me ... give them a call and see what they can offer .. i can't see other tunes compare unless run on a dyno to your and the vehicles needs, as each is unique including the customers'......

Their results found the 2.5inch exhaust system to be most beneficial with the 2.5L Motor ...
i don't have the egt probe at present. .
My mod straight through 2.5 inch muffler. .. even the guys in
the muffler shop said 3 inch was suited to larger motors eg.3L and above ....
