Harley Super Tuners

[dwjohnson]

 Hey Guys, asking about the difference between the Street Tuner and the Pro Tuner. Is it possible to modify the Street tuner cals. as far as you want to?  Like is there a limit to stop your fuel or spark tuning ability. If not, then not sure I see the need for the Pro Tuner  or am I answering my own question?

Pro tuner is the most adjustable
I believe the street tuner only allows a very limited adjustment 4 or 5 %  to keep it legal (EPA)

With street tuner you can only change VE's is certain locations like someone else said 4 or 5%.  You can only change spark small amount.  AFR same small amount.   You can't change any other parameters like engine size, injectors, cranking fuel, accel, decel, warmup enrichment or IAC.  Some of the maps for Streettuner are pretty bad also and are limited to only Harley components and they must be listed.  I have seen a couple of Street tuner tunes that were real good.  One is for the 117 street legal upgrade worked same as the SEPST tune for race 117.  The other was on a street legal tire shredder I think.

This was discussed when they first came out, the consensus as I remember was it was too limited and wasn't worth the money, I'd for sure not buy one.

 Just as I would have guessed. I'll be looking for a Super Tuner. Thanks again to everyone.

Boardtracker HD has the best price on them $350 IIRC

Only reason I can see to get one is the street legal version on 117 and 110 requires it to be warrantied. It comes in the kit.  Still wouldn't do it.
