Two years of NA tuning. Do not re-post to other groups or anywhere else. Please donate via paypal to wayne.other@gmail.com

v114, v115
- Adjusted fuel maps and load limits to work better with the new maf scales.
v113
- Petrol: Pulled some timing at high load under 2500 rpm and from 91/93/100/102 maps.
v112.Alpha4
- Changed 3rd calid in all roms back to A01 from A02, leaving all A02 data updates intact. This should enable OFT to log FLKC and IAM.
v112.Alpha3
- Patched A01G to A02G and A01I to A02I (all cal id's remain A01).
- Cal ID hacked all roms from A01G, A01I, B01C, B01D.
- Updated definitions (all definitions are now copies of A01G, A01I, B01C, B01D).
- Directory stucture is more verbose.
- Removed checksums from definitions to supress romraider messages.
- WARNING: I've taken great care to properly cal-id hack these files and double check the changes made, but you use them at your own risk. I accept no liability.
- On the tuning side these are all new maf scales that will produce different and hopefully more reliable LTFT in open loop and run port injection on e85.

If you have tactrix, you should only use one of A01G, A01I, B01C or B01D roms.
If you have OFT, you will need to use the appropriate cal-id hacked roms to match your original file.

Consolidated changes:

- 6AT: Smoothed throttle map.
- 6MT: Launch control on all roms, excluding flex fuel.

- Fuelling: Updated Primary open loop fuelling.
- Fuelling: Updated closed loop fueling to mirror open loop.
- Fuelling: Updated open loop fueling additive.
- Fuelling: Updated throttle tip in.
- Fuelling: Updated Front Oxygen sensor scale.
- Fuelling: WOT from 0-5000 rpm is 100% DI.
- Fuelling: Disabled port injection up to 0.4g/rev when cold.
- Fuelling: Update port injector scalar on E85.
- Fuelling: Updated manifold relative pressure port injector compensation.
- Idle: Adjusted cold start idle on Stg2.
- Idle: Updated idle stability maps.
- Idle: Updated and consolidated idle speeds.
- Idle: Updated cooling fan activation.
- E85: Added stock 20% PI above 5k rpm and removed it at high load, low rpm.
- E85: Low load fuel economy improvements.
- E85: Updated cold cranking.
- E85: Updated fuel mileage dash display
- E10/E85: MAF scales are exact copies of E0, multiplied by 105%.
- Stg1: Stg1 now has the same MAF scale as Stg2.
- Stg2: Disabled P0420.
- Overrun throttle angles: Under 4400 rpm are MY16 values for economy. Over 4400 rpm are MY12-15 values for increased engine braking.

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.


OLD 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.
