That's why I'm doing both Jerry. I'm

Nothing at all wrong with belt and suspenders.  Both bikes here are tuned with the PC.  There's a tuning God local and that's what he uses.  So that's what I do.  No real quesiton here.  But both have underlying tunes that could get the bikes in.

Any part can fail.  I don't doubt at all that the Power Commanders have a higher rate of failure than an onboard stock ECM.  If for no other reason than with the extra harness there's just more to fail. 

They can have electronic failures too though. Just this morning plugged a brand new one in to the SERT.  Bike wouldn't fire.  Not even grunt.  It was a bad new Power Commander right out of the package.  Grabbed another one and off we go though.  Parts is parts....

That's why I'm doing both Jerry. I'm putting in a SERT to change the parameters of the ECM, but not spending hours tuning it. Just a 90-95% tune.

So Howie, why you go 90-95% and not just get the SERT tune?

The PC is "fooling" the ECM, the SERT is adjusting the parameters ................

Other then maybe you don't have a competent tuner available.

I don't, I may take the bike to that guy who was at the NYC bike show, the guy the had the Cheery SEEG on display.

That was Andrew Rosa. He alright, but not good enough. I'm doing what Joe wants me to do. To tune the SERT perfectly he'd have to spend hours and hours at it. He can get a 95% tune he tells me within 1-2 hours. The SERT also allows him access to ECM parameters not available to him without the SERT. He's a whiz with the PC. Once he gets a good program in the ECM with the SERT, he said he can get a perfect tune with the PC on top. He said that's the best possible tune I can get. And if the PC fails, at least I can still ride the bike with a 95% SERT tune on my ECM. If no SERT, then I'm towing it if  the PC craps out. But you ain't running a 120 HP motor on a stock ECM program!

Hoist!

I know you have a lot of faith in your builder. But from the outside looking in, it just seems like someone trying to double dip ya.

Obviously I never dyno tuned a bike, but I have played around with the SERT  and from past experience with autos I don't understand the need to take such a long time to tune the SERT, especially since you can data log the runs.

If you start nit picking every 10 rpm of every parameter then yes, but I see no reason to get that detailed.
