I have seen a lot of people talking about the ecm spy and this and that, but who is a pro at reprogramming maps? I am certainly not trying to provoke argument, but who here has actually used it on a dyno to make a map for a radically changed Buell and had good results? I need help with this because I and doing some major work (head work, 88", etc.) on my 2000 x1 and I will need to convince the guy with the dyno that this will work and is effective. I also need my own peace of mind. ANYONE have a map database, or saved maps? | ||

Creature ... GooD Luck... Thats why mine remains stock bore etc. for the past 2 years...Once I see someone can Tell me YES this map or that Map or this is how ya do it Mapping I won`t go with the 88 inch kit etc... Different if it was a 1/4 mile machine /Track bike etc etc.. but for a Daily Driver not for me yet..What a Shame too...You would have thought after all these years it would be a piece of cake by NoW...! I think the guys on the Xb9`s going to the 1250 etc is alot easier than the guys wanting to go from the 12`s to the 1450`s etc.. I hope someone can PROVE ME wrong...! | ||

The problem is going to be trying to get the map you need without paying for a dyno day. If you don't find somebody who built a motor with the same combination of cams, valves, bore/stroke/RPM and fuel pressure as you are using, you really MUST spend time on the dyno. The beauty of ECMSpy is it does give you the control you need to properly tune your engine after extensive modifications. There is no free lunch - unless you can find somebody who has done a map for exactly the same motor. | ||

This guy seems to know a bit about it. http://www.xoptiinside.com/ I printed out the English manual and now Im all excited. The bit about adding an O2 sensor to the front header and using the data logging programs looks great. | ||

You can do it fine (I'm told) using the stock sensor and standard riding/data logging, but to really wring every little bit out of it you'll need the dyno. According to the directions, you can simply data log during a ride, then run the log through the free Megalog Viewer, and the Megalog software will make the necessary changes to optimize the A/F ratio for you. The you just upload the new numbers to your ECM, and viola! Tuned bike. I'm all set up to gice it a try, just need to find a good day to take the bike for a logging run. ~SM | ||

Again, without sniffers in EACH header, you're still tuning on faith. Remember, you have TWO maps - one for each cylinder. Changing exhaust systems and valves and cams does have an effect on scavenging which has an effect on the exact tune of each cylinder. | ||

what i know is the program will tune it to any combo you like. even if you find someone who did 100% exactly what you do. the maps will not be the same. as they can be at one elevation and pressure/temp and ect. all this comes into play.. as i have said many times there is not a single map fits all bikes on the fuel tables. the core files yes they can be the same but fuel tables are different on every bike. even two exact same bike in the same place will produice the same dyno numbers to the spot on but yet have different maps. explain that. it called motor breakin and other factors in the heads and ect. sa all stock bikes are not equal. best bang for the buck is get the header(stock gaskets out of the bike) replace with copper rings and exhaust gasket sealer retighten. now you just got the easyest best bang for the buck. as my xb9 had the port holes 1/4 covered 3/4 of the way around the ports with the stock tapered gaskets. tried a new set of stocks then checked the seal it was good pulled the header off and again they squished into the port opening. perfect tightening with a digital tested tq wrench. this is not good on the running. if you add the extra O2 up front you can switch the sensor plug to that and create the map for the front. but caution as the front moves the rear will end up needing adjusting. se we here that have done it find the best way is to log the front make the changes the relog the rear make the changes. then back to the front and repet. its a lot of time but well worth it. also the dyno. as i have tuned on the dyno and on the road. my fuel maps can be spot on on the dyno then be lean on the road. as the air pressure changes the maps change. this is psysics and cant be changed. third if you do the old 4th gear tune the tables will not be as good as gear tuning on the road. as you have air temps and resistance on live data. my road maps i have made give me the best actual riding feel over the dyno maps. but the timing changes can be tuned best on the dyno. then back to raod mapping the best timing marks to mesh it all in one package. if you already know a good known timing use that one. then make the fuel maps one cyl at a time. if you do the rear only copy that fuel to the front for xb9 bikes add one point to the front for xb12 add two points to the front. this seems to be the best given maps on a single o2 reading. also dont accept any tuning temps below 160 on the clt temp. just passing off my info one bit at a time. mike (Message edited by xoptimizedrsx on May 11, 2008) | ||

MIke as you say: best bang for the buck is get the header(stock gaskets out of the bike) replace with copper rings Are these the Screaming eagle gaskets I think they work good over stock as you say, or are these just some copper rings and sealer you use...If so where does one get them from thats a good point on them stock gaskets noticed that a year or so ago ... | ||

Are these gaskets the same deal for the XB12R? |
