AFR is good besides number is up and down quite a lot during idle. around 10.X at WOT and 14-15.4 cruising.
Short story:
Throw the code p0017 right away as historic code (using Torque pro app on android) after replacing timing chain at 83000 miles. Mechanic is a trustworthy person and he take it all apart again to make sure no play and everything look perfect.
I know mitsu has a TSB but my car has a tune on it... Local mitsu here said they are not working on cars have a tune on it...
My tuner said he is going to charge me another section to update the ROM according to the TSB and he will need to run the dyno again to make sure the tune transfer correctly. Is that necessary? The whole process may take me up to $600 to fix the SES light. Which be honest I am asking here because I don't have the money for it =[ . Want to see if there is another potential fix or if it is a diyable project that I can save some money...
[b]Question:
1. If I buy Tactrix Openport 2.0 cable and evoscan (My tuner use this to tune). Can I use ecuflash to update the rom and transfer the tune safely? Or a retune is necessary like my tuner said? I have Tephra V3 on the car as well...do I need to purchase a new one after the flash?
2. I research it online people saying historic code will need to run the car for a long time for the car to make sure it is right before it goes away. If I run it more is there a chance it will be gone consider mechanical part is all perfect?
Thanks guys!

Maybe your "trustworthy" mechanic didn't reset the ECU's learned values after replacing the timing chain. Typically this is done by the Mitsubishi dealer. Some very Evo-savvy shops might be able to do this too. Stick-Kitchen has a Reddit thread discussing this:
The mentioned Mitsubishi Tech Info's diagnostic procedure is as follows. I would follow this procedure and first suspect the oil control valve if the P0017 comes on out of nowhere. However, I would first reset the ECU's learned values of the exhaust valve close timing if the P0017 comes on right after a DIY-replacement of the timing chain:

Good luck resolving this issue on your Evo!
he did use a obd machine (not mut3) to reset the value. Maybe it must be using a mut3 device?

I'm uncertain, but very possibly. Dealers do use the Mitsubishi MUT3 tool for the reset. acm_evo talked about this in the past:

It would be fine for me to but a Tactrix.
Would you point me the way after I hook up the cable is there a way to download the Tephra software without paying? My tuner buy the license for me and I don't have access to anything.
