OFT - Example alternate maps for AT, 98RON, E85, MAF Scales

Note:
I now have files hosted for all MY12-16 cals here.
- On my roms you can dial in AFR perfectly on stock intake IN ONE REVISION with alternate maf scales.
- All are cal hacked from A01G/A01I/B01C/B01D, thus logging and LC work for every rom on OFT.
- No issues with unmapped DTC's or E85 cranking.
- Includes FLEX FUEL for both 6AT and 6MT.
- I've done a few MY17's now, but I've no idea about the logging capabilities for those cars on OFT yet.

ADDRESS: http://www.wayneroms.com/

While the following examples may still be interesting to some, my current files make the majority unnecessary and obsolete.



Below examples represent easily between 200 flashes to my ECU. Some of the screens are current, some seem fairly rudimentary now, but they still make decent examples.

Please see the guide below for choosing a maf scale and load limits.
http://www.ft86club.com/forums/showthread.php?t=94822


WHAT TO LOG TO DIAL IN YOUR TUNE:

Engine Speed (rpm)
Throttle (percent)
MAF Voltage (volts)
MAF g/s
Engine Load (g/rev)
Ignition Advance / Total Timing (degrees)
AFR
Commanded AFR / Target AFR
STFT (percent)
LTFT (percent)
Fuel Sys Status (2 = CL, 4 = OL)
IAT / Intake Air Temp (F)
Advance Multiplier
FLKC / Fine Learning Knock Correction (degrees)


IT'S IMPORTANT TO DRIVE 100km/60mi AT PART THROTTLE UP TO 6000rpm THEN LOG THE ABOVE PARAMETERS AT WOT 2500-7200 rpm. ONLY THEN WILL YOU BE ABLE TO CHOOSE THE CORRECT AND/OR WORK ON A MAF SCALE.


SEE END OF POST FOR DEFINITIONS AND EXAMPLE ROMS


COMMON CHANGES


O2 SENSOR SCALE (NOTE: RESCALED AXIS)

OTS (top)
v86 (bottom)



Radiator fan activation when car is at operating temperature and under 70kph.

OTS/Stock (top)
v86 (bottom)



AT THROTTLE

All my maps now have a brand new AT throttle map. The MT throttle map is more linear but doesn't work as well between shifts on the AT with longer ratios.

STAGE 1

This is useful for maf scaling. I recommend restoring port injection at 5000 rpm to be safe.

Thanks Wayno.

How hard is it to apply these same changes to the manual ZA1J___G ROMS (EU 6MT) roms?

Have you made any changes for your PSR Headers (or are they similar enough to the OpenFlash headers that they just work)?

Yep, any G rom.

Most UEL are the same. The ethanol in our E85 is mixed with worse fuel than US though, so there's some timing taken out for knock a few people have logged at 6800rpm, even though our E% is higher.

The tables for fueling/timing/fan temps/IAT compensation ect are same for manual/auto just copy them across. Assuming you have same header type.

Throttle tables are different between auto/manual.

Their is an E85 G rom attached to the first post

Did you change all/most of the tables?

Timing, fuel, cranking, do a compare with the old one if you downloaded it.

Good work.

I do wonder if there is any further discussion on long term effects of running lean even on low load but for extended times? What to look for when logging, what could go wrong? Target AFR 14.7? Is this both DI and indirect injection?

Also what happens during the warm up phase?

Sorry lots of questions

If you have a look at the stock rom fueling tables you will see it runs leaner than these tunes for higher rpm and loads.

The OL AFR fueling tables are the target afr, their are tables for the di\pi ratios but the overall target afr is determined by the ol fuel table and a couple of closed loop offset tables when running in closed loop.

Ethanol generally results in lower exhaust temps than petrol.

As always these tunes are provided free with no guarantee, run at your own risk.
@Wayno and myself have been running them for a few months and mine is running leaner tables than the ones posted here, however everyones fuel blends are different..

always check your tune is running reasnoble fuel trims less than 10%, your wot afr follows open loop fuel table and little or no knock and iam at 1.

by warmup phase assume you mean high rev cold start, as far as we know this is just to heat cats for emmisions purposes, you still need to give you car about 10 minutes to get coolant and oil to operating temps, regardless of what alterations you make to starup phase

Warm-up I usually drive very light throttle just under 3000rpm, I wondered how this could be affected by a leaner blend.
