So who wants their ECU's "Chromed"?

Also, out of curiosity, what is your reason for leaving the scaling table alone? I did all three for an VIII MAS as you probably recall.

The scaling table you used is setup for an EVO intake/innercooler/piping. When I used the EVO values on my stock 99, the trims got a bit out of whack.

Think of the scaling table as a HZ to airflow conversion table. Raising/Lowering the values on the right side of the table will tell the ECU to add/subtract more IDC for that particular HZ value. Use the fuel trims as a guide to fine tuning the scaling table if you have upgraded intake/innercooler/piping and you can't get the trims between +/-5%.

Mm interestingly put - thanks! We must have gotten "lucky" then haha. I will revisit that since things have changed a bit.

This is good to know. I was wondering this.

I am looking to fit the EVO 8 MAF to my setup and was just checking what people had to do with the conversion? wiring changes ?

Lol, seems like you all have made yours at work.

I handed a few out at the national gathering. I also have a few wiring harness pieces left to make a plug and play adapter... :-)

Hand out a few my way...lol. The harness is the easy part.

"Now open up ECUFlash, go to C:\Program Files (x86)\OpenECU\EcuFlash\Chromed ECU v1.0 and open 23861006.bin. This file is a stock tune. "

When I try to open the binary file in this step i get an "Unknown ROM image" popup with a message saying, "EcuFlash could not recognize this ROM image using any of the current definitions. You can choose one of the following options: Abort using this ROM image or Use wizard to create a new definition (NOT RECOMMENDED!!!- FOR DEVELOPERS ONLY)

What did I do wrong?

it sounds like you skipped this step:

The 3000GT folder contains the definition file. Inside the folder is the 23861006 XML file. Extract the 3000GT folder to:
C:\Program Files (x86)\OpenECU\EcuFlash\rommetadata\mitsubishi
