Flashing the 08 / ECU Editing software for GEN II Busas

Gen2 doesn't require cycling the key just gen1
Gen2 u can do fast flashes after u have done a full flash, fast flash is 20 seconds or so

Have to be honest here ........... before Petrik adjusted software my first full flash took 15 minutes >>>>>>>>>> after software upgrade (and adding some decent amount of ram to laptop) reduced to 4.5 minutes.
Whilst tuning on dyno trimming fuel map with quick flash was down to 15 to 20 seconds per flash. Once base map was sorted I can now custom map with under five flash runs. Editor to me is quicker and easier than using power commander software (I don't use a tune link with power commander)
The best part I have found is the more you use it the better it becomes as one gets a "feel" for just how much fuel to add or remove to obtain the desired settings.
Thats my 20 cents worth :thumbsup:
 
Heres a couple of pictures of the pin orientation for those having difficulty figuring out which way to insert the pins in each connector.

SmithaBusa, I would like to raise the RPM limiter and remove the 6th gear restriction on my gen II. Rather than purchase the whole mod for 200.00, which I probably wouldn't use again, what would you charge me for editing my ECU for the above two items?? TIA
 
Hi all,
I'm just new around here, I should have gone to the intro section first, but I have just spent the last 12 hrs straight reading every page of this thread (36 pages). So, if I ask any silly Q's on the subject, dont get pissed at me for not doing my research.
Not thinking real straight at the moment after that, but from what I can gather and correct me if I am wrong.

EE2 has the capability to tune the AIP map + TPS map, for the purpose of adjusting both primary and secondry injectors for a smooth transition across both maps ? Hence giving more riderability ? and reducing snatchiness on the throttle, power surging at cruising speeds ?
On the software , there is an "erase ECU" function ? WTF ??
Thanx in advance. :thumbsup:
 
when you first flash the ecu, it start by erasing its contents, nothing to worry about.

Yes you can map both the IAP map and the TPS map :)

Primary and secondary injectors work in conjunction with each other, the IAP map would use the lower injectors mostly, the TPS would use both upper and lower injectors, at peak hp ~ 80 of the fuel flow comes from uppers and 20% from lowers.

For you its easy you just have 1 table to play with for tps fuel map, the ecu figures out lower / upper injector distribution etc.
 
OK ! I thought those maps were for smoothing out the transition between the injectors, had that wrong.
I'm a non advanced user & just want to pull the limiters how would I go about leaving the fuel map in it that is already working well, when I flash I wont have the fuel map interupted unless I specify ?
What does "verify checksum" do ?
In advanced settings, should I check boxes for dynomode only when being dynoed and turn ram air compensation off ?
Thanx !
 
you can just leave fueling alone, dont mess with the dyno mode stuff if not actually doing fueling with ecu i would say. verify checksum don't worry about that either.
 
Hobo there are quite a few guys in NSW "Flashing" allready so if you run into any probs help is not far away :thumbsup: :beerchug:
 
Doouubble posts, can u tell I'm new around here ..... I somehow reversed all the threads back 2 front , upside down , now I'm really confused !
Thanx Boss, I'm not to proud to take help from anybody clued in on the subject, I noticed you are from QLD. I have just been picking Greg's brain for info coz I need to know everything bout it to educate my local dyno guy who's never heard of such a thing soooo I'm hoping to learn enuf that I can work with him on it, I sense he is a bit reluctant !
 
Hobo no problem at all and it's all a learning curve made easier by the sharing of knowledge. Have "Flashed" quite a few now both on and off bike and all results have been great.
Also a dealer for Smithabusa products with interfaces and looms kept in stock so do persist on educating your dyno man on the tuning of the future :beerchug:
If I can assist ................ just yell :thumbsup:

I think the PC III is still superior for performance tuning v.s the ECU Editor. The Editor has many good strong features, but it not possible to tune in real-time as with PC III, which is important. I visited a tuner today who looked over my PC III map, he got an indication directly on the map (the actual cell) about the TPS-value and rpm, looked at the A/F-meter and wrote a new value in the cell(s) and pressed Send To PC. The new A/F-value was presented instantly. By this method it was easy to work thrue cell by cell and optimize the A/F-ratio. He also monitored how the engine reacted to Off-On throttle transitions and could by this ensure good response on corner exits.

The ECU editor is good but at the moment it does not seem to be possible to optimize the engine without spending a hughe amont of time vs. PC III tuning.

The result of today tuning is shown below. 180+ on the wheel :cheerleader:

Well firstly I shall ask by what you mean by the term "tune in real time"
I think if you go to a tuner that has a Dynojet Dyno fitted with a tuning link set up then they may struggle as used to letting the software do the work rather than having to corelate the input settings required using their experience to obtain the correct fuel readings.
Correct fueling is correct fueling no matter how it is obtained or the methods used to obtain the desired readings.
So still wondering what is mean't by the statement as below
but it not possible to tune in real-time as with PC III, which is important
Can only think this means being able to adjust as bikes running ? Which may be convienient i will admit but certianly not important :whistle:
I note your tuner worked thru cell by cell changing settings or copying settings across to ECU Editor ................ no wonder it took for ever :banghead: And one also wonders WHY bother to do so :whistle:

Personally simply load the base .bin file ............. do a fuel run and obtain readings at wide open throttle, stepper graph run to obtain readings again thru out rpm and throttle range >>>>>>>>>>> add or subtract fuel as required to fuel cells as needed re run and check adjustment and done ?
Probably a total of five runs required. Once a custom base map for each particular configuration of pipe fitted etc >>>>>>>> even less required.
I could go on and write a small novel here, but won't >>>>>>>> simply put ECU Editor in the hands of a good competant tuner makes PCIII look exactly as it is. An antiquated "piggy back" system with the added downside of being very prone to failure.
Not out to flame any one here and apologise in advance to any it may offend, but any tuner that struggles with ECU Editor and using the flashing interface sadly isn't worth their salt.
Added note here my own bike (Gen II) had a PC III fitted along with TRE etc
Simply took of and binned unit and reflashed ECU again being honest didn't even look at the map I had custom build in the PC III as once again no reason to even bother doing so as simply built a new map. Isn't this what tuners are supposed to know how to and are paid to do :thumbsup:
Again no offence intended but could only say to owners that are spending their dollars, if your tuners struggling to build a map then I would question their competance to do what your paying them for.
Once again stress no offence intended to any party simply stating the facts as in over ten years tuning Busa's ECU Editor has to be the easiest and best by far I have used.
Cheers and happy "Flashing"

Quote The ECU editor is good but at the moment it does not seem to be possible to optimize the engine without spending a hughe amont of time vs. PC III tuning.
As said correct fueling (which is what optimises engine output) is correct fueling find it hard to understand how or why a good tuner would struggle to obtain the desired settings ?

Ryan Schnitz has tuned a number of bikes with ecu tuner and prefers it versus the piggy back type systems.

As far as taking forever, PCIII i agree does it instantly, once you have flashed once in a session, each time after that takes about 15 seconds, so maybe not real time, but i can wait 15 seconds.

There is so much more that can be done with ECU vs the other systems for a ton cheaper. I will never own another power commander, but of course i am biased:thumbsup:
 
And as for the PCIII being superior.....

This graph shows why you don't want a power commander.

A power commander only allows you to control 1 set of injectos, uppers or lowers, take your pick. They recommend the lowers, reason being is that below 5K rpm the upper do nothing, so by installing the power commander on the upper injectors would allow no tuning adjustments to be made below 5000 RPM, and probably not a whole lot above 5000 RPm if at light throttle etc.

You can see on a stock busa the upper and lower injector duty cycle's vs RPM. At peak hp, about 23% of the total fuel being supplied to the 182 hp engine is being done by the lower injectors. that equates to about 40 hp out of the total 182 hp is being supplied to the engine via the lower injectors.

So now you install a power commander on the lower set, so that you can still make idle and part throttle adjustments, and you want to start adding fuel for say a 40 shot of nitrous.

Well with the power commander all you can do is go up to +100% fuel, so you can double what the lower injector is putting out, bringing it up maybe 40 hp, i think in practice people haven't been able to get even that high.

So the solution is easy, just buy another power commander, another $300 and control the uppers completely seperately than the lowers.

What a hassle in my opinion.

At least Bazzaz lets you control all 8 using 1 map.

ECU flashing does the same, you want more fuel, no problem you enter whatever you want in ecu editor, and it asks for more fuel (via both sets of injectors).

not to mention you can do timing with ecu editor (add another couple hundred bucks for a power commander ignition module), you can remove the 6th gear restriction (add another 100 and something bucks for an X-tre, which does a crappy job at this anyway), you can use the ecu as an air shifter kill box (add another $100), you can run map switching with ecu with just the price of a toggle switch ($3 at radio shack), (add another couple hundred for a power commander hub and map switch).

I have stated my case LOL
