S&s vfi
Hey, just want to know if anyone has done a swap of the stock ECM to the S&S VFI system, I am heavily leaning towards it and the closed loop system. If anyone has done this, what were the results, or if anyone knows anyone who has done it, I guess I am just looking for some feedback here if anyone has any.....

Havn't heard alot of info about it but it caught my attention a little while back before I finally got my efi dialed in.
Member 1997Hawg put it on his and had good words towards it, maybe he will chime in.

hey bagger thanks, I searched and cannot find 1997hawg, but I am sure something will come of this....lol. I have had next to no luck getting my MM system to dial in, I have installed a Thundermax system on my bro-in-laws Dyna, it made a HUGE difference, the tunability is unmatched, all thanks to the closed loop system... That is why I want to try the S&S system as they also have a closed loop system for that year(98), but Thundermax does not......once again, thanks for your help, may see you out there one day....you just never know.

My bad, 97 hawg is his name but hasn't been active for a while.
Zippers offers a Thundermax coversion for the M&M but you need to sell a kidney to purchase

I purchased a Daytona Wego 3 tuning system ($275) and a used PC3 ($50) and got my stroked Evo running well and gets better MPG than the lighter stock twinkie I ride with. Just an idea if you are a DIY and eliminates need to trust someone else with your bike with this tuning system.

I had an '01 twin Cam Ultra with the Marelli injection. Could never get that bike dialed in either. An indy shop tried to swap in the S&S unit but wasn't able to get it mapped well at all. Ended up pulling it and going back to the MM unit. I sold the bike the next year. That was several years ago and I'm sure S&S has made some progress since the, but I didn't have any luck with it.

holy crap bagger, you werent kidding about that, 2 grand for a MM replacement system is a little steep....but being that it is from Zippers, I bet it would work well, but it is still not closed loop though....I am still looking all over for info on the S&S closed loop system....doesnt look like many people have tried it...hmmmm???
