The EF/EL one is not released yet. However CAPA gave me January 06 or earlier as the date.
Expected price is $768
Just have to wait. |

Okay, that gives me time to save up.
Now all I have to do is resist the urge to buy other expensive s**t for my car/cars.
This is gonna be hard... |

f**k 770 thats steep
how good is the ford computer wat size fuel table does it have 8x8 or 12x12 if its got a decent table it will be cool, and also wat pressure can the standard map sensor go to and will they allow you to control everything, i wish they could give us a spec list to let us no what it can do so we can no if its worth it or to just continue with our ms kits? |

I would reckon $770 is cheap, not steep, for a tuner that can access and modify a factory ECU.
Oh the possibilities... |

I would imagine that the factory ecu, even one 10 years old will be so far in front of aftermarket stuff it's not funny. And whatever it has will be more than sufficient to tune your car - it was designed for it! Also you get the benefit of 1000's of hours of factory tuning free! Insead of tuning from scratch with your MS.
I had a peek inside the software for a BA ecu, there are over 40 3D tables and 100 setup parameters just for the Auto transmisssion. -Compare that to a $3500 Motec M800 with 1 table.
Obviously the M800 is more biased for engine stuff but you get the point. |

don't hold ur breathe on a flash tuner for the EF/EL.
i'd expect one for AU's way before EF/EL, damn ford for making so many changes. |

With all due respect Spork, the V8 supercars run Motec. If the Ford factory ECU was so great, wouldn't they run that?
You seem to be missing the point of an after market ECU. From what I've read of your posts, it's like you're saying that someone with 40 sets of suspension all with different camber angles is better that one set with an adjustable camber/caster setup.
You also say that you benefit from 000's of hours of Ford tuning by using the stock ECU. Please explain to me why the stock EEC-V pisses fuel out the exhaust @ WOT.
A properly tuned engine, with millions spent on tuning combined with 000's of man hours, does not usually run @ 10:1 AFR @ WOT.
Also, ANY ECU that uses a wideband oxy sensor is going to be better than ANY ECU that uses a narrowband oxy sensor. |

Yeah but who of us can afford to run a full MoTec setup? Not me.
Who can afford the engineering hassles with a standalone aftermarket ECU? Not me.
And secondly, who would rather have a play with a working, safe, base tune, that I DIDN'T have to pay for? I'll put my hand up for that one. |

Re: The suspension analogy. No it's like having one set of suspension that can be adjusted dynamically while you are driving depending on 40 different inputs. - That would be alot better than one setting of camber castor etc that was fixed or varied with only 1 input.
V8 Supercars run motec because it is easy to tune -ie designed to be retuned constantly, it integrates with dataloggers, telemetry, etc. The factory ECU does not have these features. They also do not run the same engines as the road cars.
The factory ECU calibration is the result of a lot of testing. it pisses fuel out of the engine at WOT because over a 250,00Km drive engine durability cycle perhaps towing a trailer on a hot day with crap fuel that is what is needed to ensure the durability of the engine. Yes you can re-tune that for more power, but you will reduce your relability. This may never be an issue if your not driving at 200km/h in the northan territory on a 45 deg day with a trailer but if you did you might be stuffed.
The level of detail tuning is astonishing. How much torque reduction does your ecu give on gearshifts? How much different do you set the accell enrichment in 1st gear as apposed to 4th gear? or 5 deg as apposed to 40 deg engine temp? And will any aftermarket tuner run a durability to make sure that 99.9% of all cars with all sorts of drivers will NEVER have a problem with their tune, Not likely.
The beauty of the factory ECU is that you can make changes to the main table to get the AFR's that give you maximum power ( accepting the reliability tradeoff) And keep all the other little parameters that make the car driveable, cold start etc. as factory.
You should still tune the Ford ecu with a wideband O2 sensor (pref on a dyno). Most wideband O2's are not designed to remain in the car permantly. I am pretty sure (given the above) that FORD would have measured the AFR's while tuning. (plus a hell of a lot else). |

are you for real??
do you realy think that the EEC is not better then a motec. Are you forgeting where the EEC was developed??? if you dont know do some reaserch.
that much fuel at wot is a safty thing it prevents knock cause by bad fuel, poor servicing and posible high engine temps. you have to keep in mind that for had to tune for the lowest commen denominator (ie. the s**t most stupid person that might own/drive the car) and so things like overly rich WOT had to be done.
perhaps take a look inside one befor speaking up against it.
i mean really motec with 24x24 8860 96x32 MS 12x12
who are these companies trying to fool oh sorry |

I don't know I haven't seen the software. Athough after doing a google search EECIV tables are usually made up of lots of little tables that work together.
Anyway I would assume that whatever they are they are adaquate. |

enough for a turbo wats the timing like on them is it able to be tuned right what are the steps in rpm that the fuel and spark are updated or changed at least with out aftermarkets we are told this s**t, i tried finging ifo i cant its a pain in the a** .
all we can do is wait and see |

20mins of looking around find you alot of info.
ENGINE_DISPLACEMENT 301.082 # Engine Displacement
Defines the cubic inch displacement of the engine. This parameter us important because is defines how load is calculated. The VE(Load) is calculated by the airflow, the RPM and the ENGINE_DISPLACEMENT. Engine_displacement/(Airflow/RPM) = VE(load)
Increasing ENGINE_DISPLACEMENT typically causes increased ignition advance and leaner mixtures. This parameter is closely coupled with the MAF_FUNCTION. Double this value, and you halve the calculated load value -- that means leaner fuel mixtures and more timing. Be careful here!
LOW_INJECTOR_SLOPE 26.0995 # Injector slope lb./hr
This parameters compensates for the physical limitations of a particular fuel injector for unusually small pulsewidths (<~4ms). In general, real life fuel injectors are sloppy when the commanded pulsewidth is close to the duration of the opening and closing event time for the injector solenoid. Typical injectors take about 1 ms to open and 1 ms to close. That is a total open/close event duration of 2 ms. When the command pulsewidth is in this low-pulsewidth range (<~4 ms), the real-life fuel delivery is not linear to the rated full flow injector delivery rate. The LOW_INJECTOR_SLOPE is a fudge-factor that accounts for this deviation.
Injector pulsewidths are lowest when the RPM is high, and the throttle is closed. Idle pulsewidths are in the 2-4ms range. Larger injectors decrease all pulsewidths in direct proportion to the size increase. Double the injector size, halve the pulsewidths for any given airflow.
HIGH_INJECTOR_SLOPE(ZA0-series)INJECTOR_SIZE(all others
The fully-open fuel delivery rate in pounds(mass)/Hour, at 45 psi, of the fuel injector.
INJ_DELAY 0 # Global injector delay (crank deg.)
GLOBAL_ACCEL_MULTIPLIER 0.398438 # Global Accel pump multiplier
FAN_TEMP 220 # Coolant temp for Electric Fan (Deg F)
Fan operation temperature in degrees Fahrenheit.
FAN_ENABLE 0 # Electric Fan control enable(0=no, 1=yes)
1 enables fan operation, 0 disables
LOW_DWELL 0.500008 # Max low speed dwell (off time in ms)
Coil charge time in milliseconds. Don't know what the purpose of this is.
HIGH_DWELL 0.2 # Max high speed dwell (off time in ms)
Coil charge time in milliseconds. Don't know what the purpose of this is.
OPEN_LOOP_FUEL_MULTIPLER 0.996094 # Global open loop fuel multiplier
Across-the-board fuel mixture adjustment when operating in Open Loop mode (non HEGO controlled operation). Numbers less then one richen the mixture (increase fuel delivery) Numbers greater then one lean the mixture (decrease fuel delivery)
EGR_MULTIPLIER 1 # EGR multiplier
This is a gross scaling adjustment for the flow rate of a given EGR valve. Use a number larger then one to proportionately add more recirculated exhaust gas to the intake charge. Numbers less then one reduce the EGR flow.
For example, setting EGR_MULTIPLIER to 0.75 would deliver three fourths the amount of exhaust compared to stock. A setting of 1.5 would deliver 1 and a half times the EGR flow. Don't know why you would use this, but its fun to change the values and log EVP sensor output (pin 27).
EGR_TYPE 0 # EGR type (0=sonic, 1-PFE, 2=none)
Set to 2(none) to remove the EGR related error codes for a removed or non-functioning EGR. The effect on fuel mixture and ignition timing is unknown -- probably stays exactly the same.
The Purge canister solenoid still works when the Thermactor and EGR are set to none. The Purge Canister solenoid opens at off throttle, car warm, and running for 5 minutes or so.
SECOND_SPEED_LIMITER_ON
The _ON must be set higher then the _OFF for this function to work. The engine cuts out when the speed on the speedometer reaches the speed set with SECOND_SPEED_LIMITER_ON, the engines starts running after the speed falls off to SECOND_SPEED_LIMITER_OFF
FIRST_SPEED_LIMITER_XXX
Doesn't seem to do anything.
Possibly used on automatic equipped mustangs, or when the car is under/over operating temperature.
HALF_FUEL_REV_LIMIT_ON 8000 # Turn on half-fuel rev limit
HALF_FUEL_REV_LIMIT_OFF 7500 # Turn off half-fuel rev limit
The _ON must be set higher then the _OFF for this function to work. The PCM cuts fuel delivery in half when the engine speed reaches the RPM of the _ON value. Fuel delivery remains cut in half until the engine speed drops below the RPM set in the _OFF speed.
NO_FUEL_RPM 7000 # Max RPM (no fuel)
Cuts all fuel when this RPM is reached. Harsh rev limiter. Avoid its use.
MIN_LOAD_FOR_CLOSED_LOOP 0.00500488 # Minimum load for CL control
?
TIME_AT_HIGH_LOAD_BEFORE_OPEN_LOOP 2 # Time at high load to force OL (sec)
The TIME_AT_HIGH_LOAD_BEFORE_OPEN_LOOP is the numbers of seconds that the car will stay in closed loop (HEGO fuel control) when it detects a high load demand (anything over about 1/3 throttle). A 0 works here also.
THERMACTOR_PRESENT 1 # Thermactor present (0-no, 1-yes)
Set to 0 to remove the Thermactor related error codes for a removed air pump belt or non-functioning air-diverter/air-bypass valves or their associated solenoids.
NUMBER_OF_HEGOS 2 # Number of HEGO's
Set to zero to force Open Loop fuel delivery operation?
MIN_ECT_FOR_FUEL_SHUTOFF 140 # Min ECT for decel fuel shutoff (Deg F)
MIN_RPM_FOR_FUEL_SHUTOFF 150 # Min RPM for decel fuel shutoff (Deg F)
MIN_ACT_FOR_ADAPTIVE_CONTROL 100 # Min ACT for Adaptive Control (Deg F)
MAX_ACT_FOR_ADAPTIVE_CONTROL 200 # Max ACT for Adaptive Control (Deg F)
?Does Anyone use these? The Cobra (X3Z) changes these values from the A9L, but I don't know why?

INJECTOR_FIRING_ORDER # Injector firing order

EXHAUST_PULSE_DELAY # in Engine Revolutions
This is the amount of time in engine revolutions that it takes the exhaust charge to reach the oxygen sensor after ignition. Increase this value to improve idle on cars with long tube headers.
Here is a more specific definition contributed from a someone in the EEC-EFI mailing list: "EXHAUST_PULSE_DELAY is the time between when the injector
pulse width is calculated in the EEC (*not* when the injector
is fired), to when that pulse ends up reliably sensed at the HEGO
sensor. This is used to predict when the O2 signal will cross so
it can get the correct amplitude and bias results."
From an EEC Tuner user point of view, longer headers mean larger values in the table. Conceivably, changing the injector timing table could also have any effect here (I would presume only a negligible one though < 1).

HEGO_AMPLITUDE
Description taken from an EEC-EFI mailing list contributor:
" HEGO_AMPLITUDE is the desired amplitude of the O2 dither signal. This is modified primarily for emissions - it is set up to optimize the catalytic converter performance. A certain minimum is required to maintain the system in a limit cycle oscillation."

HEGO_BIAS
Description taken from an EEC-EFI mailing list contributor:
"The HEGO_BIAS allows the averaged air-fuel ratio to be shifted slightly rich or slightly lean. This makes virtually no difference in power but it has a huge impact on emissions. This is used to adjust the CO-HC vs NOx balance on the emissions test cycle. A rich mixture will lower NOx but raise CO, a lean mixture will do the opposite."

show me an after market ECU that can doo all of that. better yet show me one that can it and only cost the 700 to $1000 that the tunner is likly to cost.
by the way all of that is only a small portion of what i found and only some of the things the eec does and takes into acount |

Autronic is serious stuff. You haven't tried installing some/all of it yourself? $1000 for install sounds like alot how many hours is it going to take them?
Let me know how it goes with the autotune thing! Also if you hook up traction control (sounds like you'll need it with that setup!) it would be interesting to hear how that goes too!
Good point with the tuning. A well tuned stinger will still outperform a poorly tuned motec so make sure you factor in the $$$ for tuning. What are the going rates? |
i have a Autronic ECU in my race car.
i wired it up myself in a few hours, its not that hard. although i sent it to JPC for the tuning. |

tickfor_6: I found that info too. I think it's from the EECIV from a V8 Mustang.
EECV is supposed to be alot more advanced and for I6 it uses a MAP so will have some different tables to control that.
Really I see only 2 disadvantages with the standard ECU
1) No Data logging. -Not a problem for me I use the vehicle datalogger!
2) No Realtime tuning - Will make dyno tuning slow. But no worse than a Stinger and you already have a REALLY good basemap. |
