Well, I took a hint from senate a while back about upgrading to a eclipse 501 MAF . I swapped the MAF out and used ecuflash to copy all the settings from the eclipse ecu to the lancer ecu. The settings I copied were for the MAF scaling, Maf size , Maf smoothing table and Maf Sensor filtering. Here is a picture of the differences between the two... Senate was there anything else you copied in for the maf swap?


Lancer left ----------------------------------------------------------------- Eclipse 501 right



Here is the writeup by senate figured i'd link , looks like he put some time and thought into a very nice post...

Nope, you got it right.

I hope people will stare long and hard at this pic you posted and follow your lead to switch to the 501 MAF. I've been running a 501 MAF since Jan '07 and don't see having it any other way. You will not regret this mod. The picture speaks for itself.

 

So wait, this just plugs right into our harness and everything? where could I find the values to copy in with the ecuflash?

 

I have wanted to do this swap since I took mine off the clean. It is so small. I just don’t have ecu flash o can you post the stock eclipse setting for those who have the 501 and ecu flash to scale it.Nice job on the swap

 

Here are the values from an 2001-2003 Eclipse GS ROM:

 

no adaptor required?

anyone know the part number?

 

Nope. No adapter required. They are the same exact size. Difference is in the inside. The Mitsu part # is MD336501, if that helps. Just look for the big "501" on the label. The Evo is 399, just for reference.

 

Awesome. Thanks

 

so from what im gathering other than this is a no brainer mod to put in, what years eclipse is this off of? i gotta run to the salvage yard on friday anyway!

 

No brainer to install a maf.
You need a little more to copy values from one ecu to another.

 

+1

While the MAF install itself is plug and play, if you don't know how to properly use EcuFlash you run the risk of messing up your ROM.

The 501 MAF was found roughly on the following vehicles:

ECLIPSE 00-02
ECLIPSE 03-05 exc. GTS
GALANT 99-03
MONTERO SPORT 99-03 3.0L (6 cyl)
OUTLANDER 03
SEBRING 01-05 (Coupe)
STRATUS 01-05 (Coupe)

After looking through the Mitsu parts lookup last night I realized that the 501 MAF is not limited to 4-cylinder engines. For example, the 501 MAF was used in the 2000-2002 Eclipse GT, which is a V6.

 

no brainer as in the size wize. i didnt mean it was going to be anything as a drop n go style. i know that you have to change values in the ecu.

 

Maybe you know. But some kindergarden kid who read your post may think it's as easy and swap and go.

 

OMG im so happy. My mom wrecked her 02 montero sport and its sitting in her front yard completely totaled with engine intact. Thanks for the list on that. Yay!

 

hopefully some kindergarten kid wouldve been smarter than that because if you read the thread so far senate posted some values that you need to change. that and this thread hasnt hit 2 pages yet.
