Some dude lend me this ecu and check which evo it belong so I put that into my buddy's IX. When I read the ecu, it fail (using Evo9 read template). Then I tried Evo7/8, that work. The romid come up is 97710001.

I was told later this ecu is from IX RS, so I copied 88570008 and make it work with 97710001. Scaling is a bit off but timing and fuelmap is good. VVT/Mivec map doesn't seem to work.

Question is, this rom is 256k in size. Does IX RS have Mivec? Here's the rom if you are interested to find out.

Here's the output when reading using E9.

ROM can download here

 

Here's the picture of the ecu.

 

How did he get his hands on an "engineering sample"?

Anyhow, Evo 9 ROMs are 512 KB. Using the Evo 8 read method will cause the ROM to be 256 KB. How many times did you try the Evo 9 read method?

 

Fred,

I tried 3 times E9 read with OP1.3 and OP2.0 with Ecuflash 1.40. Still failed.

 

Sounds like this may be some prototype or developmental ECU. Where did your friend get it?

 

He is doing forwarding business, lots of used parts are import directly from Japan including this ecu.

Well I guess it's alright, this ecu is not useable in any car.

 

MIVEC is at 585d, axis:6812,6844

 

Wow, thanks acamus
So this is IX ecu indeed... what's the Valvetiming scaling used?

This doesn't work for me...

<scaling name="ValveTiming" units="degrees" toexpr="72-x*0.6" frexpr="(72-x)/0.6" format="%.1f" min="0" max="30" inc="0.6" storagetype="uint8" endian="big"/>

 

There are only 14 elements for RPM, and 20 for load axis

 

"VVT Map 2 (Not Used) Future Use" is at 5980 but its size is 0.

 

 

if you need some other addresses to be corrected, please post, i will have a look.
Anyway thanx for posting this ROM, it seems it could be used with evo7/8 ECUs.

 

That's all I need to clarify, gonna pack it back and return to the owner. Not taking chance put it in any car.

 

Has anybody used this ROM with VII-VIII and IX MIVEC head?
