ok if the evo 8 ecu works for the lancer, do I need a fuel management system, I called road race and they said I needed a standalon system. I need help on just this part of turboing my car.

If i get the evo 8 ecu
440 cc injectors

will this be my fuel management system?

and do I need to replace the maf sensor on my car to make this work?

I have a TD05HR 16G 9.8 T turbo. Please help!!!

 

Honestly, you don't even need the Evo VIII ecu. The Lancer ECU is tunable. But, the Evo VIII ECU is a better option as it is set up to handle boost. But to answer your question, yes, the Evo ECU is your fuel management.

If you use the Evo ECU, I believe it's recommended to use the matching Evo MAF.

 

arent the mafs the same? thats what i heard

 

Nope, pretty different actually. The settings are very different between the lancer and lancer evo maf, not to mention the size. You would just need to change the settings in EcuFlash.
Here's a lancer maf, then the eclipse 501 maf, then the evo maf:

 

what size diffrence are we talking about? if i have the long ram intake system would the air filter i have still fit? or do i need to buy a new filter?

 

also will the plugs for the lancer and the evo be the same or do you need a new sensor plug

 

The plugs are the same, and fittings/adapters are as well. What do you mean what are the size differences? Look at the openings in the pictures...
The exterior dimensions are the same.

 

Unless your motor is seeing boost, I don't see a need for upgrading the maf like that...

 

The size is not the only factor when considering upgrading your MAF,
it's the amount of air flow that it can meter.

Obviously, the Lancer maf can only meter so much at a certain point
and begins to lean out with higher boost levels.

 

my bad I thought you meant one was bigger than the other I was worried about installation issues
