In the ISCV values on these two XMLs of which are supposed to be nearly identical I found a issue....

Which "Engine Temp" address is correct for the series?????

The reason I ask is because I am trying to adjust the "Air Temperature Compensation" temps to suit my climate, but every time I change the temp value it also changes the ISCV temp values. Also I believe that the Air Temp Comp table will help to del with cold weather idle issues with intake pipes.

If someone could post stock ISCV and Air Temp Comp values I would much appreciate it.

 

interesting...

I have always had a bad idle, and I dont remember if it started after I switched for 08 to 15 or not....

 

they are probably both correct. As different revisions of the ROM get released, you are not garrenteed that the module addresses will remain the same.

IMO, this just indicates that some Mitsubishi programmer was working on code in or near the the code locted in and around the address in question. when the code was built, the compiler and linker placed the code at a new location to make room for what ever changes occured in the new revision.

 

The idle tables all use Engine Temp, not Air Temp, which if you have been trying to tune them is probably why you are having problems.

The scale address you have for 94170015 is an Air Temp address. Try it at 67a2 which should read correctly as Engine Temp. I just quickly saw that there are 4 scale addresses with the exact same temp scales, but any of them will do the job so long as you arent editting the temperatures. You should always be careful doing that, because there is alot of sharing going on in the Mitsubishi code... it is just a temperature lookup table after all.

 

For 94170015 I have

Intake Air Temp 689e
Engine Coolant Temp 68b8

 

Intake Air Temp 689e
Engine Coolant Temp 68b8

works great

The Engine temp 67a2 works also.

I will test both and get back to you
