As a last resort to improve performance on my RE Himalayan 411, I installed Powertronics V4 and dyno tuned it. Here’s how it went and here’s my review on it.
For context my Himalayan has a BMC air filter, NGK iridium spark plugs, TEC cam, FuelX pro, a decatted exhaust pipe from HT exhausts and a Powerrage exhaust. The only restrictive link in the entire chain was the ECU. Hence getting a piggy back ECU and tuning it was the next best move.
So I approached race dynamics and they agreed to install their latest Powertronics V4. They also agreed to dyno tune it and make a custom map to fully utilise all the performance mods I had installed. They installed the map switch as well.
The installation took around 10-15 minutes and the dyno tune took around 15-20 minutes. They tuned 2 maps. One with the dB killer and one without. Powertronics aims to improve the horse power & torque and fix fuelling issues if any.
Together with the FuelX, it should work better to improve the overall performance and smoothness. But does it make a difference in real life scenario? To answer that, let me get into the pros and cons.
Pros of Powertronics V4
1. Improved fuelling
As soon as I rolled out the bike out of their centre, the first thing I noticed is the improved fuelling. Whatever minute jerkiness the bike had in fuelling at some RPMs, even after installing the fuel X, was completely gone. I never noticed the bike had small fuelling issues until it was resolved. The throttle seemed much smoother, linear and predictable throughout the entire rev range. Overall the bike became a lot smoother and calmer to ride.
2. Improved throttle response
The bike became a little more peppier. The ever so slightest delay in the throttle was gone and the response became almost instantaneous. This made the sudden accelerations in overtaking and off road riding a bit more fun.
Cons of Powertronics V4
No performance improvement
After dyno tuning, according to their charts, the bike got just around 2bhp of increase in power and 2.5Nm of increase in torque. But in real life I didn’t feel any improvement at all. The acceleration remained the same. The top speed improved by around 5km/hr but that’s due to the rev extender feature of Powertronics. So for the amount of money you spend on the unit, the performance boost you get is almost negligible.
Now I’d like to get into something that you should be aware of. My Himalayan is a BS6 2020 model. And I noticed a certain pattern. All the videos of people I have seen on youtube boasting around 5-6 increase in bhp with Powertronics and another 5bhp of increase in power with TEC cam are the owners of bs3/bs4 vehicles. I wondered why and asked around.
So apparently the ECU of BS6 bikes are heavily restricted to comply with the emission norms. Not only did this affect the bhp of a stock BS6 bike but it also restricted the amount of performace boost you could get with performance mods. Here, even powertronics cannot override certain limitations of the BS6 units. This wasn’t confirmed by race dynamics but it’s what I heard from users in certain forums. It makes sense as to why I gained very minimal increase in power or torque even with dyno tuning.
Who is Powertronics V4 for?
If you are looking to improve the overall smoothness of the bike, reduce the fuelling issues and run the bike in a much calmer and quicker way, then powertronics is a good upgrade. It makes the throttle response quicker, smoother and more linear and predictable. But do not install it expecting noticeable improvement in acceleration, top speed or even the torque.
Is Powertronics V4 value for money?
I do not think it’s a value for money product. For a mere increase in smoothness, you are paying 19000 INR for the powertronics unit and 1500 for the map switch. With that money you could go for better chain sprockets, tires and engine oil which improves the smoothness of the bike. So I don’t think you should get one unless you have some cash to spare.
