Update:
I've had the ZL1 Splash Guards installed for about 3 months now and they're holding up very well....
Initially the instructions were incorrect and they also were sending out the wrong hardware...Just make sure you use the correct black screws for the rear guards and plastic replacement...
There has been recent posts on a few A90 Facebook groups by tuners using Ecutek, BM3, and MHD...Apparently, the latest OE ECU updates lock out any tune flashes done through OBDII port...There were a couple of folks that recently took their tuned vehicles into service where service flashed an ECU...
My biggest complaint with the audio system had more to do with vibrational noise that the subs create rather than the sound quality of the system itself...
After eliminating most of the low freq vibrational problem areas by adding sound deadening material and playing with the audio EQ settings...
Has any progress been made to gain access to ECU for flash through OBDII for those that have their ECU's updated and locked?
Also, how do you determine if the ECU is accessible prior to purchase?
Question for those that may be considering purchasing a flash tune...
Is there anyway to find out if your Supra has had an ECU update done? I understand that for those who purchased their Supra after Nov there is a very good chance an update was done during prep and your ECU is locked out from...

Update:
I got a call yesterday from OEM Audio Plus letting me know there has been a delay in release date of their new system for the Supra which was originally planned for April and now looks more like late spring ...
Some other info they shared was that they have been refining the new system...
I removed active sound design a while ago which did help cleanup the low bass sound quality but did nothing to reduce low freq vibrations...I have doubts they added those 3 elongated ports with ASD in mind...I'm fairly certain those 3 elongated exhaust ports where added in an attempt to reduce...
Yes, I did play deep bass music with the narrow cover panel removed...Bass seemed to have a somewhat deeper response with far less low freq vibration...
That insulation you see on the narrow cover plate isn't thick enough to cover over the 3 elongated openings...The insulations is apparently...
Here is a closeup...I just verified visually by removing narrow rear panel that our subs are indeed ported directly below their woofer enclosures...With heavy bass played it's amazing the amount of air pushed out through the 3 elliptical slots shown on attached pic....Also of interest is that it...
I found this pic posted with rear woofers and enclosures removed...wondering if the woofer enclosures have ports on the bottom of their enclosures? See chassis cutouts shown below...
Rear OE woofers with enclosures shown below:
Anyone following this audio upgrade option by OEM Audio Plus? It's still under development...
I like that this system will also offer multi channel amp and dsp...My understanding is that with this kit our current "subs" would be used as woofers (using cutoff filter) and that an additional sub...
