posted updated adx and xdf, nothing of importance just minor updates

updated a9l2 and gufx posted

[decipha]

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.

[decipha]

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.

[decipha]

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.

[decipha]

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.

posted new adx xdf and a9l2

previous a9l2 was from 24-01-03, been pretty significant code upgrades in the past 2 years. most notably now is fn337/fn338 and dashpot

previous xdf was from 2024-feb. Again significant upgrades code wise since then.

adx is unchanged but newer one has all the histograms in it, might as well

enjoy

Just added SPKCTL code to only permit idle spark control during decel, this prevents FN111 from commanding wot timing when the tps fails. Also allows FN111 to be set to same as primary spark table and allows fn839 dashpot closed throttle multiplier to put significantly more torque reserve in on decel (perhaps x 0.383)

I realize this does the same as nulling fn841 & fn839 and using fn111 for static decel spark but doing it this way allows dashpot to control the actual reserve.

any case i'll try it out and see. if its worthwhile it'll be in the next update.

just rewrote the lugtmr code to allow tip in tq reserve for smoother transition out from idle.
