no, there is no problem loading any map on newer rockets on top of that there is no problem with penner map at all. Thousands have done it on newer rockets. I am in to tuneecu group and I see people press buttons on apps which they shouldnt.
its very easy process unless someone does something very wrong.
I've answered your statement before. You are saying that anyone who has a problem with the install is doing something "very wrong" and I'm going to, once again, take issue with that.
I've been using TuneECU for years (2011 Roadster) without incident, yet on my 2020 3R I encountered a problem. Was it me? Did the battery voltage drop despite being on the charger? Did I get a counterfeit OBDLink Bluetooth LX off Amazon? Or, was it just a random grimlin? Who the Fu¢k knows.
I would caution you against guaranteeing that with your help it will go flawlessly, or that anyone who runs into trouble is at fault. Yes, thousands have loaded Penners tune, and other tunes, into their Rockets without issue. Chances are excellent, statistically, that will be your experience, as well, if you are reading this and considering it.
I did finally get his tune loaded in my bike and I'm VERY happy with it (I have given the fist bump to Penner here many many times and appreciate the gift), but what I will not tell someone is that there is a 100% guarantee that because I've done it that it will go well for you (this is a ECU thing, btw, nothing to do with Penner's tune). That would be irresponsible. Likewise, I would not say with 100% certainty that just because the technique I used to recover the ECU worked for me that if you run into trouble it will definitely work for you, or that if it doesn't it's because YOU must have, therefore, "pushed a wrong button."
The standard procedure IS very easy. Push a wrong button? Can you give an example, or two, of what wrong button someone might have pushed to cause an issue?
Be careful becoming an expert at something just because you've done it with success before. $hit happens and it happens in the world regularly. There are no guarantees.
