In all my years of doing this, I've never seen that XDF or that Scalar text (EXPERIMENTAL spark angle). Whoever developed this XDF did not know what they were doing or they were using if for an engine that had a Distributorless Ignition System (DIS). The parameter at the address of that Scalar (0x28) is the Maximum Retard allowed for a distributor 8 cylinder engine and SHOULD NEVER BE CHANGED!!!!!. That's why it's not in any valid XDF except for S_AUJP.
First thing you MUST DO is to correct your BIN to get this value back to -3.87 degrees max retard:
-Using your weird XDF, change the value back to 90 and save it
-Select the Hex Editor icon in the TunerPro banner
-You should see at address 0x28 and 0x29: FF F5
-If that's not what's there, change it to FF F5
-Save the BIN
Next, dump your XDF and only use the attached. You can now make changes to the BIN with confidence. This is the XDF that can be downloaded from tunerpro.net, modified to edit some additional items as described in the attached documentation.
Not to complicate things, but when you get the spark straightened out, you need to upgrade to S_AUJP v6. Very easy to do and can tune/change/report virtually everything.
