v108.1, v108, v107.3
- Re-shaped OL Fueling to be slightly leaner in the mid range.
- Adjusted US.Lean MAF Scale
- Added Stg1 with smooth AVCS for comparison against vanilla Stg1.
- Added ZA1JF20Q.
v107.2
- Adjusted load limits (WOT) under 2500 rpm. No other changes.
v107.1
- Trying to squeeze more power/economy and better shifting out of 2000rpm only. No other changes. Please compare against v107 only.
v107
- FLEX: Adjusted cranking and fuel compensation.
- ALL: Adjusted overrun/decel throttle open angles with MY16 tables (more open angle, less engine braking, most likely to improve economy).
- AU.Rich: minor MAF scale adjustment.
- ACE/EL: minor AVCS adjustment.
- ACE 98: minor fuel adjustment.

v106
- Further smoothed v104 AVCS

- Fixes AT bogging after shift around 2200 rpm as much as possible.
v103
- v103: Original openflash AVCS tables as per v100.
- v103A: Much more finely grained and linear AVCS tables at partial throttle. These fix most bogging after shifting in auto mode on AT, and should benefit MT also.

- Smoothed out the throttle map for AT.
- Tweaked fueling.
- Tweaked timing for 98.
- Tweaked intake air temp timing compensation.
- Consolidated a few tables so 98 and E85 maps can be directly comparable and ready for open source flex fuel, namely:
-- Open Loop Fueling
-- Closed Loop Fueling
-- Base Timing B
-- Knock Correction Advance
v99:
- Consolidated regular Stg2 and BPB ign timing.
- Consolidated load limit scaling for easier compare/editing.

v86
- E85: Added most of the OTS power(timing) back under light throttle/low load/cruise while only sacrificing a fraction of the economy. The timing in that area has been further smoothed but is more aggressive than before, but not as much as OTS. There is extra fuel in some areas compared to before to mitigate knock.
- 98RON: Updated load limits to help power between 3000-4000rpm.
- BOTH: Developed different load maps for EL and UEL.
- Can fairly reliably predict which of 2 maf scales to choose between for any car on 98.

- (AT E85) Fixed lean condition at 2500-3000rpm, due to load limits.

v48
- (E85) Added 0.3 deg timing back at 3600rpm
- (E85) MAF scale copied from Stg2 petrol. This will make you run about 0.3 AFR higher (leaner) in WOT and have lower trims overall.
- (E85) Mild update for open loop MAF scale portion, so that it doesn't go as insanely rich after 6600rpm.
- Disabled port injection up to 0.3g/rev for smoother throttle tip in from idle

Example Maps (this file):
http://www.ft86club.com/forums/showthread.php?t=83945


Throttle changes

- MT throttle map is unchanged
- MT throttle map was unsuitable for AT shift points
- AT throttle map has been smoothed slightly
- AT throttle map doesn't ramp up like crazy at 1% throttle


PETROL Timing changes

Aussie 98 RON is worse than US 91 AKI. The original timing maps were fairly inconsistent and lumpy. I've smoothed them out so that not as much timing needs to be pulled to keep IAM = 1.


E85 Timing changes

Smoothed map and made some adjustments to run leaner under medium loads.


E85 Cranking changes

<0C stock values multiplied x 1.4
10C stock values multiplied x 1.5
20C stock values multiplied x 1.4
30C stock values multiplied x 1.3
40C stock values multiplied x 1.2
50C stock values multiplied x 1.1
60C stock values multiplied x 1.05

If you are having trouble cranking, try these:
- Add 4L-5L petrol per tank
- Press the starter once with the throttle flat to the floor (nothing visible will happen), before starting normally.


MAF Scales

People in the U.S. should use the otiginal Openflash MAF scales (and timing maps, and fuel maps, etc).

They are not so good for AU/EU.
If unsure, try the "Rich" version first.

"AU.Lean"
- Closest to stock scale
- For MY14 and later AT and a few MY14 MT on E0
- Not applicable to MY12 MT and MY13 MT

"AU.Rich"
- 5% Richer than "AU.Lean" at the top end
- For MY12 MT, MY13 MT, most MY14 MT, possibly some MY12 and MY13 AT on E0
- Possibly could be required on MY12 AT and MY13 AT, but haven't seen evidence of this.

"US.Lean"
- Default scale for MY14 and later AT and a few MY14 MT on E85
- Not applicable to MY12 MT and MY13 MT

"US.Rich"
- Closest to Openflash U.S. E10/E85 scale
- 5% Richer than "US.Lean" at the top end
- Default scale for MY12 MT, MY13 MT, most MY14 MT, possibly some MY12 and MY13 AT on E85
- Possibly could be required on MY12 AT and MY13 AT, but haven't seen evidence of this.
