I have not done that for a long while. I will at this time give away the how to's along with pash v2 tuning guide you cant go wrong...
as for tuning I use dual widebands on all bikes at the old shop. i even have a dual setup on my street bike and race bike. i ran it this way on the dyno to make the base maps for aprox 8 different pipes. this was done for the xb12 and xb9. from there tables were made to avg changes. over all its a guess from observations. for non dual censored bikes.
just because you made pipes bigger or shorter free flow or back pressure. doesnt mean it needs more fuel. you need to read the afr you may have made it more efficient actually needing less fuel in many areas.
I stopped for two reasons 1. it was ecmspy and not to be commercially done (begin to eat at me for doing it). 2. time to do it correctly as some expected a one time upload. which never matches files to the actual bike. best resolution was stop totally. regroup and give away my many days of training and info gathered from the dyno,track and street from the 4gas and dual widband info over a couple years time. I actually built an engine just to test with. I also wore out two tires on the dyno doing test. It was well worth the effort.
all of my maps did use more fuel cause i like it more rich living in a very hot climate.
14.7 burns to hot where cooler 15.4 is to weak on the hp IMO. so i was setting cruise at 14.0 and open loop at 13.2 in most cases.
timing on all ecms was moved at idle time to all six up front at the lower idle a 9 and rear a 6 on all six zeros. makes for a more smooth idle every time and egts actually dropped.
needless if you have questions pm me or email i will tell what i did in full and why.
read the V2 tuning guide its great.
see
