Attached is a performance video for the Monster Fuel ECU flash for the F3s, F3L and the RTL. This was my RTL and I beat the heck out of it doing all the testing. You can see the gauges and hear the sounds. Notice the second test run on the video where the front tires are floating and are not making contact with the ground!

I wanted to share my recent Monster Fuel Stage 2 flash. I waited until my 3-year warranty ended for my 2021 RTL. I sent my ECU and my friends 2023 RTL ECU in for a Stage 2 flash. Turn around was reasonable, about 9 days thru Wick-It and Mr. Colman. My last ride was a 2016 F3L that had the faster gearing over the RTL. The F3L gearing accelerated quicker and was an absolute hot rod. Not so much with my 2021 RTL. In the lower RPMs below 4K the bike feels much the same as stock. Here is where the flash is most notable.
1. From a standing start if you want to really get moving, once you get to about 4,200 RPM in first gear, things really come alive. If you shift north of 7,300 RPM you will be going 90mph plus which is about all I need from my RTL.
2. The best thing the flash does is give you GREAT passing power even riding 2 up. Example: 3 vehicles in front of you is a car going a little slower than you would like. The cars in front of you are reluctant to pass and without the flash I would have just lost hope I had enough power to pass 3 vehicles. NOW, I shift down to 4th or 3rd gear around 50 MPH and by the time I clear the front car I'm going 100 mph when I pull back into my lane. The flash took time for me to really calibrate what my new power could deliver safely.
So, bottom line is the power is really noticeable above 4,200 RPM. The engine sounds like it should, mean and nasty. For merging onto the Interstate, it's very comforting knowing the power is there to quickly match Interstate speed before you leave the entrance ramp lane. Having real passing power riding 1 or 2 up gives you confidence you can pass safely.
Conclusion: The flash will deliver outstanding results for the F3 sport line. For F3L and RTL owners, because of the taller gearing, there is a delay to get to the power area of the flash. This is not a big issue. You need to be aware of what gear you are in at a given speed and be willing to down shift as necessary to get above 4,000 RPM to tap into some exciting power delivery.
Bottom line is I like more horse power and my RTL stock was really lacking in this area. Now that I have the Stage 2 flash, it puts a smile on my face when I tap into the new power.
