Detuned hyperstranda and WTB a engine ecu

kobefans · Jul 6, 2015

its somewhat ****** up fact that i will spend about 25k us dollars for my hyperstrada here in China! and it is detuned to 93 hp"¦

only way to get it back to 110hp is to change it to a us or euro spec engine ecu⋯⋯

do u guys know how much will it cost? or where i can look for a used one?

Cheers!

It's about 903 at the crank. Regardless of whether it's detuned or not,that's still a lot of power - what would the extra 10% really get you for your money.

And if it still has the orginal ecu, you should be able to have it remapped back to orginal....even if you have to pull it out and post it off.

exactly - buy a rexxer evo user, install a rexxer map and you have full power

Better is go for a Rexxer Mapping that's it!

100% with ferdi!

could you pls educate me on the rexxer evo thing? do i have to send in my ecu for the tune? and how much hp do i get out of it?

just wanna get my money worth, 17hp is a significant difference

a rexxer mapping can be installed at a dealer who is a rexxer support point.
if you want the original verison again or some other changes, you always need the rexxer dealer again.
besides -i doubt there is a rexxer support point in china.

rexxer evo user you can buy online here: :: RexXer ECU-Tuning ::

when you have received the little box/display, you connect it with the enclosed cable to the diagplug of your HS, follow the instructions and read out your original map.
then you connect the rexxer-box via usb-cable to your pc and load down the original.usr file and send it to rexxer guys in germany per email.
they will send back to you a tuiningfile which contains your wanted tunes + the original file.
you load this file from rexxer germany via usb-cable onto your rexxerbox and afterwards you connect the box to your HS again, follow the instructions and load the wanted tuningfile onto the ECU of your bike.
finished.
if you choose tuiningfiles without lambda and exhaustvalve you also have a much more smooth running bike.

at any time you can load back your original mapping from the box, connect lambdasensors and your bike is in original status again.

of course lambdasensors only have to be disconnected with a mapping which disables lambda.
rexxer also has mappings with lambda, then nothing else has to be done than load the new rexxermap.

gained hp: minimum the hp of an original (us, european ...) HS

wow ferdi, thanks a lot for your response, so much help!

Correct me if i am wrong, by installing a rexxer map, my detuned HS will change from 93hp( Chinese version ) to 110hp (the rest of the world), right?

And also what is lambda and exhaustvalve ? What do they do? Care to elaborate?

Thanks a lot in advance !

i cannot imagine any other hp reduction than via the internal map of the ecu.
when you install a map of a 110hp version HS or a rexxer map, your 93hp should be out and 110 ore more should be in.
of course i am not 100% sure because i do not know how Ducati detuned the chinese HS. but i think they did not use other cams, injectors or some other hardware when detuning it per SW is so easy.

lambdaregulation = change AFR in closed loop to about 14.7 = lambda1 with O2 sensors. i suppose larger bikes, cars ... in china have this also ?

yea as far as i know it was a change to the ecu mapping to decrease the hp output in chinese version HS!

Also what set up of mapping would you recommend if i decide to go with rexxer? And what is the advantage of using such setup?

thanks

another question, i was told that there is something called DDS (ducati diagnostic system) which will deny other device to re-map the ecu? is that true?

maybe, but not for the rexxer, otherwise i would not have been able to remap with rexxer, and others also.

mappings: if i would be on your side i would order 2 maps:
1 original map with lambda and exhaustvalve active
1 rexxer mapping without lambda and without exhaustvalve, both for original exhaust, except you have an other exhaust, then you should tell them

if you want your rexxer mapping tuned also it's up to you. I personally did not feel a difference. maybe there is one on a testbench

Be interesting to know why the detune and before doing anything I'd see if the dealers can tell you how they are detuned....it could be as simple as a restriction plate ( but best guess is that it would be the mapping of the ecu).

Finally, how friendly is the dealer and can they assist??

the detune is to meet Chinese emission standaed(ironic here as China is the most polluted country in the world, they have tight regulations on motorcycles )

and as far as i know it is only changed from the ecu mapping to decrease the hp output

finally im fairly familiar with the ducati dealer here

i alrdy talked to the dealer, they dont know ****! they mostly just sell bikes, no real mechanics here

Hmmm.....so how do you feel about them serving the bike...and where do you go for warranty work?

I can't image Duc allowing a dealer to operate with out training etc.....

thats the thing! they probably could do basic maintaince like oil change etc, any other issues they probably need to consult Italy on how to do it"¦

ducati just tapped in Chinese market for like two years, they are slowly building their network here⋯⋯
