Oct-29/2023 I wrote delta-n code for fn810, dashpot and fn111. They no longer need to be updated for changing idle speed.

fn338 code revised to correct unsigned lookup

A few of the new code tunes are running around will post an updated a9l2 and xdf when time permits.

Updated a9l2 and gufx posted. FN111 revamped, all dashpot is now rpm error based and corrected some lookup malfunctions on fn338, fn320 and the like.

My FN1035 backflow code wasn't being used for CT and WOT as intended instead was being used exactly opposite at PT only (when APT__bit0==0) (opcode 30 instead of 38)

I also wrote a low throttle backflow patch to force fn1036 use below a 20 tprel over 1500 rpm.

New xdf will be posted once I verify this time all is working as written.

Added FN337 function code (at 0xA17A iirc) to jump in to open loop at any rpm and load for those that peg the maf in the part throttle range to still have full resolution. Can also be used for good stuff otherwise as well if need be.

I'll post a new a9l2 and gufx file soon.

Just added a TP_RATCH_MIN clip to prevent ratch from dropping stupid low with jittery TPS's. Not something you'd ordinarily use or need but can help diagnose and identify tps issues easier without the engine revving high from setting part throttle while you tinker.

Will be in the next update with fn337.
