BMW 330e 2.0 B48 2020 G20 292hp - ECU Remap and Tuning Module Dyno Test

In our latest dyno test we have this 2020 G20 BMW 330e in for tuning and testing. We run two separate tests here, one with our 3 Channel Pro Petrol chip tuning box and the other coming from an ECU remap. The result… Some pretty awesome performance gains…

We have featured many of our hybrid tuning solutions on this channel and this G20 330e doesn’t stray too far from what we’ve already showcased. The 111bhp electric motor is paired with very capable B48 engine, which we have already seen a lot of in previous tests, so we already know the tuning potential from this set up. However, as we find most often, the engine comes de-tuned as standard from stock, not giving you that full potential of its power. We can soon have that fixed, and show you what it’s really capable of…

Now as this is an early 2020 manufactured G20, it doesn’t in fact have a locked ECU, unlike many that have recently featured on this channel, so we have all tuning options available to us here. This is a good reason as to why it's always worth checking with us first, as many will sit at the cross over point, having either an unlocked or locked ECU. Dyno testing before and after each tuning option, shows healthy gains across the rev range, with a significant increase in power and torque, really transforming how it feels to drive.

First, we take a look at the tuning module. Peak power was significantly increased, as we were able to lift it from 303hp at stock, up to 399hp with the box. If you take a look at the dyno graph below you can see how we change that curve (dotted red and blue lines). We give real consistency here, bringing that extra power in as soon as possible, whilst holding it for as long as possible throughout the rev range. We really lift that entire mid-section, adding that +96hp at its peak, really transforming how it feels out on the road. Torque also saw some excellent improvements. At stock the engine produced 469Nm and now 617Nm with the box. If you take another look at the graph (solid lines), you can really see where we have applied those gains. You can see that we have lifted every part of the rev range, delivering that increase exactly where it’s needed and then adding the +148Nm extra at its peak.

Now we can get even further enhancements, so we removed the tuning box and proceeded with a full custom ECU remap. We were able to get even more peak power, lifting from 303hp at stock, up to 408hp after the remap. If you take a look at the dyno graph below you can see just how much we open up that mid-section (dotted red and green lines), adding that +105hp at its peak. Not only that, but we can see increases throughout every part of the rev range. Taking a look at around 3200rpm for example, you’ll see increases of around 120hp-130hp, showing real improvements in exactly the right places. Torque had phenomenal improvements. Lifting from 469Nm at stock, up to 794Nm after the tune. Again, looking at the graph (solid lines), we can see just that sheer difference between the two. It holds that uplift across that entire mid-section, adding that +325Nm extra at its peak. The car will feel completely different, responding much differently now out on the road.
