Look .. think of the engine as YOU ..

ask yourself this question .. you breathing out thru a straw is easier or you breathing out thru a 0.5" pipe ?

Now using this same pipe, you use the straw as the exit point .. don't you thnk its easier INITIALLY to breathe out but then you hit he bottleneck of the straw later ?

YOU are having problems because BEFORE you even hit the bottle neck . you've already changed the flow characteristics of how the engine behave ..

All these are possibilities .. once the car is no longer 'stock' .. you're fair game to how the ecu think what is stock ..

There is no mystery to this ..

If you're really free .. go flip over the BOV .. I'll guarantee you'll trigger 3 codes .. P1235 P1238 and P1241 .. but have you changed the flow in anyway ?? or changed the way the engine breathes ?? .. answer is no

Trust me .. with the X .. just get it tuned .. the mitsubishi techs will NOT EVEN know its been changed .. they can only read the serial number of your ECU rom.. but not the contents ..

 

Interesting. Well, one of the things I DO want to do is go and get the Cobb AP. So maybe that's the route to go, rather than getting a custom tune that I can't change. Plus, my understanding is that a tune alone from the guy here (Tobz) is more than half the price of the Cobb AP.

Well, should have the car back today, so we'll see how far I can make it before it triggers the code.

And yeah, I Agree. If this problem comes up again, I may start pushing them to put the stock downpipe back on.

 

The accessport might not be the best solution for you with it's off the shelf maps.

Get an ECUFlash map from a local guy that can support you and you'll be happier IMO. I had an accessport and switched over to ECUFlash.

The support of gunzo, tephra and the others on the forums is invaluable.

 

It's easier to breathe through the bigger pipe, of course.

But breathing would not initially be easier with the straw, because when I push air into the larger part of the pipe, it still must displace the air that is in the large part of the pipe, through the straw. And without compressing the air inside the larger part of the pipe (which COULD be happening in that larger downpipe), it doesn't make it easier to breathe. The displacement must still happen via the straw. That's my thinking behind it. So, I guess there's a tad more air that can be placed in part of the system, but the overall capability of air flow through the exhaust is still the same, only that one part of the entire exhaust system has slightly more volume for air in there. Either way, the rest of the system is still a bottleneck, which makes the speed at which it an breathe, the same, but gives it slightly more air capacity.

I like these problems that make our brains work, lol.

 

ECUflash is good. But don't forget that the Cobb AP allows to change to different maps very easily. For me, switch between maps ez is the best feature.

 

I agree with that, but it also gives me the ability to get it custom tuned...

What made you unhappy with the AP that made you switch?

 

This is true.

 

I know this has been brought up before but never received an answer. Is there any proof they can read a flash count? I've heard from some pretty reliable sources their isn't any proof. Can anyone confirm this?

 

Yeah, I thought they could see the number of times it had been flashed, and if so, they could tell how many times it should have been flashed based on previous work...

But hey, if they can't tell the Cobb AP has ever been on there, how would they be able to tell if any other flash had ever been on there?

 

Exactly. The AP is great and all, but it isn't as powerful and accurate as a custom flash. In the end, I didn't feel it was worth the $700, especially when I can get a Dyno Tune ECU Flash for $350.

 

Damn Ricky, sorry to hear about the bad luck. Hope it all works out for you....

 

how much was the MAF Sensor?

 

bump for an answer. gunzo? kijima? anyone a mitsu tech here?

 

Yes, you can dependant on the tool you are using.

You have to be more specific in your question. If you were to ask if your dealers MUT III could see a count, then the answer would be no.

 

You can get custom tunes with the accessport people. It's not just a generic map tool.

I think it's a great device and swapping maps is VERY simple. My issue was that I planned on making changes and $3-400 per retune was out of the question.

I was also able to make modifications to my tune using ATR (AccessTunerRace), which is similar to ECUFlash, but for AccessPorts (although the maps are turned 90*).

So, as to what the products can do... it's pretty similar. One simply costs more money and has a large name company to support it (Cobb) and has fancier hardware.

There's no obvious better choice, but having local support is VERY important IMO. Personally I'm lucky in that I have both Cobb and EvolutionDynamics (KevinD) in my backyard, so I can make a choice.
