ANDY C

I used a different laptop this time and installed the same update files and firmware files on it and it installed the 1.4.1 firmware no problem...

How do you roll back the Firmware exactly? I'm have issues with my A/C which i'm sure has only started since upgrading from 1.4.1 to 1.5.1 this is on LEM G3 in a MY00 WRX. I open up the firmware update for Version 1.4.1 to try and roll it back but it can't find the ecu, this is with no other programs running on the laptop or PC Link connected???

I'm just going off personal experience and i've been through 2 of them and now the 2nd is inaccurate compared to the wide band. CLL would target and AFR of 14.3 then using the narrowband channel from the LC-1 it was spot on 14.7. I'm not an isolated incident with 02 sensors failing in classic shape subaru's.I and others believe it's the location of them being just after the turbo, also it's probably why Subaru have moved them mor downsteam in the newer models.

Also i wouldn't use the standard subaru 02 narrow band for CLL as they aren't accurate enough , use the narrow band channel from your LM-1 and splice it into the loom before the adapter link..

In the gauges runtime display it would be good to show an actual digital value under each gauge, also i'm with above "Autotune or Closed loop AFR maps (using wideband)" or it be good to put afr numbers in the fuel table and let the ecu target them instead of pulse width numbers..
