ECU cracked for remapping...for real??

On a whim I emailed ECUnleashed after seeing an advertisement last week.
http://ecunleashed.com/mv-agusta-tri...-network-news/

They are saying they've cracked the Marelli 5SM ECU for my 2007 F4R and can fully remap. Unfortunately you get a canned map.
Anyone care to comment? ::
I'll check this thread once it reaches 10 pages.

Hello Mike,
Yes, that is what sets us apart from the competition, we are not just going off the TPS and a single fuel curve. We change ignition timing as well as fuel tables for complete optimization. We are also able to lift all the factory speed and rev limit restrictions. At this time they are not tuneable by the end user and we load our program straight onto your ECU, however we are able to fine tune each individual flash for specific modifications to the motor.
Let me know if you have any other questions,
Thanks

Hey ECUnleashed. There are many people out there offering 'remapping' of the Magenetti Marelli IAW 5SM ECU. But these are just resetting the TPS and adjusting the single fuel mixture base curve. As you know the 5SM for the MV Agusta has the adjustments for timing, rev limit, etc locked from any user adjustment.
Are you saying you guys have fully cracked the 5SM and allow unrestricted timing adjustments and fuel mapping adjustments at all specific rpms?
Are these tunable by me using your software or are they preloaded and “canned”?
Thanks
Mike

I care to comment. Two years ago I posted up about my local dyno guy working with a renowned tuner from the Midwest U.S. to do just that. They used my 312R, with the Marelli 5SM, as their test pig to do quite a bit of mapping and ECU changes...including changing the running temperature a bit. It took them a looong time, but my 312R runs very well.

I am not sure if the same guy/guys are working with ECUnleashed, but you might try contacting Rob's Dyno in Gardner MA http://www.robsdyno.com/ and askingh im some questions. That's my 312R on his home page....

Keep your words soft and sweet, for someday you shall eat them....

Chuck is spot on there. It is of very little use if someone can re-write the ECU, but have no map to put on the thing. Running the bike on a Dyno is the most efficient way to know if your map is better than OE, or if you are making improvements rather than making it worse.

NO! data logging Lambda is, on the road in the real world

dynos are for all out race motors, where you're looking at 3/4+ throttle

put a lambda meter on your ride and see how bad factory maps are

this is a real ECU;
http://www.rbracing-rsr.com/turbo/sq.../sq6m_hand.jpg

its a Pectel SQ6M
the hand holding it is my buddy Bob
he makes real ECUs too

here is his software take a few seconds and learn something;
http://www.rbracing-rsr.com/autocal.htm
real fuel injection not crap from an dead end electronics museum

his turbo Gixxers held all the 4 cyl Bonneville records from '89-'02

here are my buddies Marc and Micah last year at the Texas Standing Mile;
http://www.youtube.com/watch?v=GXm-v61po1E
that was Saturday listen to Micah "its holding, its holding....." it didn't blow up
Sunday they went 200.8MPH World's Fastest Twin

i helped so did Bob

Noel, how about the Microtec auto tune kit in manual mode, I know it's not a data logger but you can get real time road ridding AFR numbers with it? One problem is ya don't know ya throttle position and can't log it.
Any way to get around not knowing the T/P while ridding?

With all due respect this belief that dyno's are for race engines and only real road riding can tune a bike is quite frankly bollocks.

The map in that M226 of yours that you like so much was written on a dyno here thousands of miles away from you yet it seems to be doing alright.

I write maps from idle upwards on a dyno and have great results all the time so why this idea of race bikes and only mapping full throttle on dyno's exists is beyond me. I do road test but i use the road to test for throttle reponse and how well the transients are blending together and for overall "feel" but in terms of accuracy a dyno with a good operator is far superiour.

Every example that you post up is for a forced induction engine but you apply these examples to naturally aspirated engines and the two are totally different beasts with totally different tuning requirements.

I've also done some tuning with Autotune systems/lambda's and whilst they are better than nothing you do need to have a stratergy of how you will approach the mapping process and know exactly what you want the result to be otherwise your throtle movement can be too fast for the lambda to lock onto and sample.

These systems these days are mutli layered 3D systems with an exhaustable amount of variables and tuning options. Approaching them like the good old days of changing jets and needle settings by ear is lauaghable. There are far too many variables for this to be precise in my opinion.

When I chatted with an ECU Unleashed dealer they indicated they could map individual bikes on their dyno as a "tuning center", not just install the pre-written map....They paid extra for that license.

I used to be fast....now I just dream about it.
