I was told by dealer where I bought my 18 SGS, that a SE Pro Street Tuner and Power Vision were required to keep warranty when doing a Stage 1 or above. Anyone else heard of this? Sounds like they just want to sell more parts.

 

Also I bought the extended warranty, if that would make a difference.

 

That’s kinda ridiculous never mind it doesn’t make sense... get them to put that in writing lol.

 

Yea kinda what I was thinking, they said they would tune it with the PV and put the tune on the SE Tuner and if it was hooked up to a computer MoCo would only see the SE Tuner to keep the warranty. So a PV voids warranty? Couldn't get a straight answer from service department.

 

A load of crap that is. The PV is superior to the street tuner. But they are both tuners. Tuning with PV will get a good tune Pretty much only the VE can be pasted into the street tuner and then flashed to the ecm. But some of the PV data already in the ecm will be overwritten. Really do not know if they are scamming you or they do not know what thye are doing.
BTW, the SE street tuner flash will protect your warranty.

 

Well if the PV overwrites anything in ECM, maybe that is what they mean by using the SE Tuner. I will be calling a couple other dealerships for a second opinion. I can install my own air cleaner, and head pipes. Already did slip-ons. Just wanted dealer to do Stage 2 (cams and dyno).

 

The ecm comes with a stock map. Either/any tuner will write over the stock map. using an SE street tuner is the only tuner they (HD) say keeps the warranty. The PV is capable of fine tuning the timing and more. The SE street is limited to a preprogrammed file for HD only add on parts.

 

Got it, thanks for the info. Going to do some calling around and see what I can come up with. May be able to get away with just SEPST at another dealer. Just wanting more sound and power from M8 like everyone else

 

if the Mothership finds they are using a non compliant tuner on an otherwise compliant tuned bike they are in deep doo doo $$ penalty wise..that's a huge no no

 

Here is what they are likely doing, they are probably loading a map from the "Street tuner" and then pulling it and modifying it with the PV, When read on the Digital technician it will read "street tuned" I have seen this at a local dealer and verified it myself
