Hi,

I couldn't find over the net the stock ROM for a 2004 EDM Lancer Evolution VIII RS so here I am asking for some help.

The car has been tuned and I'd like to get it back to stock.

What I know:
EVO VIII RS
Engine and turbo completely stock
ECU part number is MR578511
With antilag system
Without MAP sensor on intake manifold
With ACD
Without AYC
Without ABS

 

Get someone local to read the rom for you.
There are way too many Evo8 roms to even take a guess at what you might have in that particular car.

 

This is as close as anyone will get you as far as I know. Only two options show for a 2004 EDM.

do you know the rom number?

I have a RS 2005 EDM

My car has no ABS, SAS antilag system, ACD, and stock rom internal ID is 97470001, Market JDM says the rom info

LMK

 

Right now the car is far, far away.

I sent to a especialized shop for a complete maintenance service (brakes, clutch, plugs, fluids, belts, pulleys, tensioners, a new O2 housing plus gaskets, etc). It has the OEM boost solenoid connected but boost is controlled by a MBC. After all the maintenance the boost came up to 1.9bar! The shop turned it down to 1.0bar on the MBC but I asked them to try the stock solenoid to see how it behaves.

I am pretty sure it has some tuning but haven't had the opportunity to dump the ECU to check it out. Can only hope the boost wasn't messed up until I can get the car and work on the ECU.
