Finally got around to using Forscan today. I bought a HS/MS ELM327 from Amazon a couple years ago but I never used it. I was about to buy another one when I vaguely remembered having one… good thing you can search your Amazon history. But where was it? When I found it I remembered what happened. It arrived with a mini cd with “drivers” and the bag had a sticker saying “disable antivirus and firewall”.
When I saw that I said “Not today…” and chucked the whole thing to the side. I ended up throwing it in a box with electrical components to collect dust.
Well I found some drivers and was able to get the ELM327 up and running without using the mystery disk.
I tooled around changing the normal stuff… global windows, Bambi mode, etc
Searched online and found someone had said they thought they had better audio after making some changes on the DSP. I made their change and it seemed better. Then I played around with the numbers. I ended up with much better audio and a fader that is near equal!!!
WTF. I had my car at the dealer to fix this issue at one point. They even replaced the DSP or APIM. (Don’t remember which)
Oh well. It seems great now.
Below is the setting in the DSP.
783-02-01, I changed the second digit 0X00. *Update: 0x0x should be changed together. FORscan will fix it if you only change the first x but will show a checksum error. Started with 6 and went up from there. C seemed to be great. I also changed the third digit which changed the last digit from 0 to 9 🤷♂️
Number combos tested: 018E, 028F, 0390, 0491 (stock RS), 0592 (Escape w/Sony), 0693, 0794, 0895 (Focus ST w/Sony), 0996, 0A97, 0B98, 0C99, 0D9A, 0E9B, 0F9C.
My default setting was 0491. Current setting is 0996. It had the best balance of working fade and loudness adjustability.
This made my day 😆
Compared as built data to Focus ST and Escape with premium Sony sound systems.
