trialsertl Posted October 25, 2013 Report Share Posted October 25, 2013 seeing as how i've got two standard throttle bodies, i just wondered if any enterprising electronic engineers out there had ever opened one up or compared the internals to a twin map ?

woody Posted October 25, 2013 Report Share Posted October 25, 2013 I remember someone telling me a few years ago, they went to a local Honda dealer they were on good terms with to see if they had any leads that would fit the standard throttle body. The assumption being that it must have been mapped in the first place so there must be a way of mapping it. This was before Sandifords went and before Honda wanted all their road bike dealers to stock off-road models. He reckoned they did it with the same mapping lead as used on a CBR600. Np idea if this is fact or not, just reporting what he said. Quote Link to comment Share on other sites More sharing options...
dadof2 Posted October 25, 2013 Report Share Posted October 25, 2013 Honda used to supply mapping software and leads so you could "tune" your bike using a laptop. There is bound to be several 4rt owners who have this kit. Probably available as an optional extra on new 4rt. Quote Link to comment Share on other sites More sharing options...
woody Posted October 25, 2013 Report Share Posted October 25, 2013 But that was for the 'mappable' throttle body, which the standard throttle body isn't Quote Link to comment Share on other sites More sharing options...
fantic303 Posted October 27, 2013 Report Share Posted October 27, 2013 I can write a book on my experince with the hacking of the ECU. Started with cutting open a standard ECU and finished with an unsatisfied fealing. The standard body has also two mappings, a homologation (road legal) and competition mapping activated when you remove the lights. It is possible to change the mapping of standard body, but you must have the software which is right for the standard body. The connection leads will also connect to the standard ECU but the software we can buy is not right for the standard ECU. If you use the single stage software on a twin map ecu you will get get an error message on your screen and in the other way also. An other way is to tweak the software we can buy. I have done this with the single stage software which i now can use for a two stage ecu and for the twin map software which is now usable for the single stage ECU. Connecting direct to the ECU in the way they do with the factory Montesa's is in my opinion the easiest way but ...... My knowledge of EEPROM and EE programming is almost zero so i can't go any further. Till now it cost me hundreds and hundreds of hours to come to this point. I have made for myself the decission to stop with it. Quote Link to comment Share on other sites More sharing options...
nigel dabster Posted October 27, 2013 Report Share Posted October 27, 2013 So if you want to play about buy a programmeable body and the leads? Quote Link to comment Share on other sites More sharing options...
