I'm looking for some help reading the rom on my 2007 JDM Legacy Spec B. I can test write roms okay, but fails to read the rom from the car. I get a "invalid / no kernel response to read"
It test writes the factory rom okay, so assuming rom isn't locked (which I feared)
On test write, and compare the rom is identical to the factory rom, so I'm assuming it isn't tuned in any form.
'Factory' rom I test wrote
https://github.com/bludgod/RomRaider/blob/master/JDM/Legacy/A2UG000k-2006-JDM-Subaru-Legacy-GT-spec.B-MT.hexIf I knew it would work okay I would flash the stock rom over the existing rom (appears to be stock) as a test to try, but scared of bricking the ECU since it's having issues downloading the rom.
Car:2007 JDM Legacy GT Wagon Spec B, 2.0L, 6 speed manual, Si Drive (2007 as verified by VIN, per the def file for this CALID the ECU is 2006, car was made Nov. 2006)
From RomRaider Logger:CAL ID: A2UG000K (Listed as a 2006 ECU with experimental defs, others have read roms and flashed okay thou)
ECU ID: 4B04785007
AndyMac has read this rom okay on his car
https://www.romraider.com/forum/viewtopic.php?f=5&t=10861https://www.romraider.com/forum/viewtopic.php?f=8&t=12826What I've tried:1 - I've tried 2 laptops, a newer dell with the an existing install of EcuFlash, then uninstalled and reinstalled EcuFlash with new defs. And a second laptop with a fresh install of Windows 10 and EcuFlash.
Both have identical behaviour.
2 - Test mode connectors connected and disconnected (from what I've read they can be disconnected for Can ECUs)
3 - Verified it's going into test mode with RomRaider Logger. It doesn't flash the CEL light with connectors connected unless the engine is started, and doesn't cycle rad fans or click relays. Runs like it's in test mode when started and flashes CEL.
4 - Tried sti05 and subarucan flashing methods - subarucan works for test write, sti05 will spit out the ECUID then fail.
5 - Unplugged and replugged the OpenPort cable a few times
6 - Played with the timing of 'read', tried clicking okay on the read pop up window then immediately turning ignition on, starting with ignition on then hitting okay, pressing okay waiting a few seconds then turning ignition on.
