Hello, I am trying to flash a manual rom to an auto ECU that is on an auto 2005 Lancer (not a USDM model) that was converted to a manual transmission. I have seen on here that people have done this before. The reason I want to do it is because the auto ROM is throwing an error code because the auto tranny has 2 speed signals and the manual only has one signal to the ECU.

I read the original ROM using the Evo 9 read mehtod and get a 512kb file. The manual ROM is 256kb and the xml has the flash method as mitsukernel and the memmodel as SH7052.

So if I open that ROM and try to flash I get:

So next I tried changing the flash method to mitsukernelocp:

So then I tried changing the memmodel to SH7055 and then I get:

Anyone have any insight into how to get it to work? Thanks.

 

BTW, this car uses a MAP sensor from the factory so I cannot just flash an Evo 9 rom to it and modify maf and injector settings etc.

 

Hmm your kind in a bind because your year model requires ocp which means the rom needs to be of 512kb size.

You could try flashing with my rom and disabling all the errors with the master disable odbii error codes table i defined. Or get someone to help define it on your current rom not sure what else would work.

The only way to probably get the rom for a manual on your car is to extend the bits to 512kb size which can be done with some clever tools but i don't simply have the time to make one for you :/.

 

I don't think your ROM will work because this car is SD from the factory. Even if you have an SD version of your ROM it would take a long time to dial it in.

Your idea of creating a 512kb file is a good one. I think I can use a HEX editor and get that working. I will try and see. Thanks.

 

I created the 512kB file. I am going to meet up with the owner this weekend and try it out.

 

Just make sure you filled the rom with zero's at the END of the file. Its very important you don't fill it with zero's from the top.

 

Yes man, thx.

 

UPDATE: I flashed my 512kB ROM to the car yesterday. It runs perfectly fine except for the cooling fans. They are on permanently once the ignition is on and they turn off when you turn the a/c on. So its is as if the logic is working backwards.

This car has a factory pwm fan controller that controls both of the fans on the radiator. I am guessing that the ROM I flashed to the car does not use the PWM controller. I'm going to do some research and figure out how to get around this problem.
