So bench flashing the 2011-2012 to the 2010 works like a champ?

Good to see that it might just be cams that are less aggressive causing the power losses.

 

if this is true its abosulte bull****. I think we all need to contact mitsubishi corporate and give a formal complaint. Its obvious the car isn't making the advertised CHP.

I still don't get why the one car you did made perfectly fine power?

 

Not sure what you mean "if this is true". I did the test, the data is available, it appears that was what was needed to correct the issue.

10-80-10

10% are sub standard
80% are average
10% are exceptional

It wont do any good to complain. This is not the first time this happened with Evos as I outlined earlier with the 2004 and the 2005 with the weird cam phasing. They sell a car at a rated bhp, not whp so unless someone pulled a 2012 motor and harness to show it didnt make the correct bhp on an engine stand they will laugh.

The car needs cams, its not the end of world.

This x10.

However, if someone were to pull an engine and test its chp and it did not produce at 298hp, then we have a problem and a class action lawsuit on our hands. Keeping in mind, the purchasers of the car would see very little and the lawyers would see much.

 

What year cams did you swap with?

I'm bummed. It isn't the end of the world but its ****ing bull**** that my 2012 evo isn't as up to par as its previous years. So now in order to get the proper power I need to swap cams and flash my ecu to 2010 in which case I'm ****ed if I have any warranty cause they'll see that right away.

 

I have to agree with this. For someone who wants to keep their warranty in tact, this cam swap would be a big problem.

So what specifically is different about the cams compared to the previous models? And I'm assuming the 2013 will be the same way?

 

I just cant figure it out, why mitshubishi would spend money when times are hard to develop a new camshafts , make them and pull the old evo camshafts off the production line. Then re write the already fixed ecu map for the new camshafts. I am to only one wonders how much effort in reality is actually need to do this?
Unless the ralliart camshafts are the replacements for the evo camshaft.... but as i heard they are a same.
so? Any ideas?

 

If you are worried about your warranty, your car shouldn't be on a dyno or being tuned anyway.

People get so worked up over such little things. If you want to mod your car, you mod it and deal with any **** that goes wrong, its just the nature of the game.

Think of it this way, now doing cams on the X is worth it...and now you just throw some good aftermarket cams in there to make it even more worth it. Glass half full

 

I agree and mine has not. I am 100% stock, never raced, never tuned, and never dyno'd. I need my car as a DD and will not touch the car mod wise until I have exceeded my warranty coverage.

That being said if the cars are down on hp then mitsu has falsly advertised the hp numbers. I understand whp is different from hp but if a stock car is down 20whp, I think it's safe to say its down hp.

And I have said it before but I have not been impressed with the Evo (acceleration wise) in it's stock form. I am sure if I had an additional 20whp I would certainly feel it.

 

Well I think the real question is what are the baselines on your car vs. other years. I can almost guarantee the 08's were lower baseline wise than your 2012. None of the 08 owners care, because it was all tune related. On the most recent years the tune has been changed from the factory a lot. So maybe the hardware is different but if they modified the tune that doesn't mean the baseline HP is any different.

So with different hardware they can still get the 291 or whatever advertised crank HP because they can tune other stuff more aggressively, or honestly more appropriately.

The issue is once you do full bolt ons and tune your car is lower than other years, well guess what, that isn't stock so people need to relax

I know it sucks somewhat for those who like to mod, but remember 2012's have plenty of **** fixed that us 08 owners had to replace ourselves that equals a cam swap anyway. So I don't feel sorry

Like I said, glass half full, do a cam swap that shows gains now! yay.

 

That is right, the 08' s supposidly has a worst tune ever in evo history.

 

It's been stated by a couple of tuners on this thread that stock for stock the 2012's are coming in about 20whp less then the 08-11. Even after a tune only or a tune and bolt-ons they are coming in with less power in comparison.

Honestly I really don't care and will just deal with it. I think it's BS for Mitsu to advertise a certain hp if it is not achieving it. I also think it's BS to make the Evo slower then it already is (in stock form mind you). But that is just one of the many reasons why I will NEVER buy another Mitsu vehicle ever again. This Evo was my last purchase for sure. I will just deal with whatever hp my car has stock. And then when I'm done or bored with it, I will just sell it and pawn it off onto the next guy. I certainly won't be buying new cams thats for sure.

Eitherway if the 2012's are for sure down on power because of the cams then the word should be spread if possible. Especially to the 2013 guys because if anyone intends to keep their car stock they may be disappointed and I would assume the 2013 will be the same way

 

Look at it from someone's perspective who doesn't plan to mod the car.. If the car baselines low on power then its obvious in stock form the car lacks power from precious years. So now someone spends 40 grand on a car that needs another 800 dollars to be up to par from previous years. Not to mention now you'll have voided your warranty swapping cams. Regarding the 08's, its always a toss up when a car is first released that it will need many improvements in the years to come, people are aware of this..

I also find it hard to believe that Mitsu changed the cam profile from previous successful years. Its not like cams will have a major effect on emissions. Its not like the cams sucked previous to 2012. I could see however that they changed manufactures and the profiles changed by accident.. Just isn't adding up..

 

I'm getting tune next week and I have a 2012 GSR. So is it a guarantee my car will make less power than previous year with basic stage 2 bolt ons?

 

I have the same question. When you figure in the tooling/machining costs to change the cam profile, then add in the man hours of Engineers required to re-write the ECU mapping it doesn't make financial scense.

There are 2 reasons I can think of why we would do this in the auto industry.

1. Fixing a field related issue. Are there any engine reliability issues with stock Evo's?
2. VE (Cost savings). Here the tooling costs & programming costs would have to be recovered over the remaining volume of Evo's which is <4K for MY12 & MY13.

So which is it?
