HP Increase

[Rawze]

program EF10054 has the following features ...

advertised as a 450HP at 1650 ft.lbs torque.

- Actual power is set for 1650 ft.lbs.. Actual HP crests at 490HP at 1600 RPM though.

power/ramp/rate limiters ...

1. (Ramp up/down rate limiting based on engine acceleration noise) = active

2. (After-treatment unit torque limiting) = clamped to 2150 ft.lbs (this is considered inactive).

3. (Anti-Theft/engine lock-out power limiting when Anti-theft is active) = limits engine to 50% output power when active.

4. (Altitude based fuel limiting tables) = all are active but set slightly above the 450hp/1650 ratings.

5. (Fuel limiters for individual injection pulse cycles) = all are active but set slightly above the 450hp/1650 ratings.

6. ( Dynamic Torque Reduction) = Active. Is set to clamp the engine to no more than 14.7 ft.lbs per second ramp up/down rate limiting. This setting helps clamp sudden torque changes to help save fuel by reducing the response rate of the engine. Many people do not like this feature, as it effects overall engine response.

7. (Engine Overload Protection Limiter) = Inactive.

8. (Power Train Protection Limiter) = Inactive.

9. (Fuel Rate Limiter) = Active. Many people do not like this feature, as it effects overall engine response.

10. (greenhouse Gas speed/power limiter) = Inactive.

11. (Gear-shift torque limiter) = Inactive. Is not available in the CM2350 model engines.

12.(Integrated Fueling Control solenoid total on-time limiter) = active (but set higher than the 450/1650 power/torque rating).

13.(Load Based Speed Control Torque limiter) = Active. Most truck owners absolutely hate this limiter, as it holds the engine back quite a lot in the lower gear ranges + makes the truck feel sluggish when bobtail/light loads.

14.(Machine Torque limiter) = Active.

15.(Smart Torque Limiter) = Inactive.

16.(Smart Torque2 Limiter) = Inactive.

17.(User Selected Fuel economy Power curve Limiter) = Active. Many people do not like this feature, as it effects overall engine response.

16.(Machine Mass Estimation Manager / road-steepness Limiters) = Active. Many people do not like this feature, as it effects overall engine response.

18.(Oxygen Fuel Control / Fuel-Air-Mix fuel-Limiter) = Inactive.

19.(Operating Zone Limiter) = Inactive. Is not available in the CM2350 model engines.

20.(Predictive Cruise Control Power curve Limiter) = Inactive.

21.(Road Speed Control Limiter) = Active. Many people do not like this feature, as it effects overall engine response.

22.(Gear Down Protection Limiter) = Active. This feature causes accelerated wear in the engine over time. Most truck owners hate this to be active, as it makes truck feel weak in lower gear ranges + severely limits rpm to 1500 and below.

23.(Cummins Inpower Torque limiting options Power vs. Fuel economy Power curve limiter) = Set to "Max fuel mileage" instead of "Max performance". - "Max fuel mileage" is the most restrictive setting possible, however it does help a tiny bit with saving fuel.

24.(Smart Road-Speed-Governor Limiter) = Inactive.

25.(Turbo Fuel Control fuelling-Limiter) = Inactive.

26.(Vehicle Acceleration Rate Limiter) = Inactive.

27.(Vehicle Speed Sensing no-load RPM Limiter) = Inactive.

28.(Engine Warm-up Protection Power curve Limiter) = Active.

============

Besides the actual torque/power settings, the items listed above and settings are what is seen in in the EF10054 program from the factory to limit torque, fuelling, power, ramp up/down rates, etc.

Also, I only know of maybe about 2 people on planet earth (besides myself) that could properly and effectively adjust all of these 28+ features on the fly individually without mucking up the rest of the programming into oblivion. Some settings are obvious, some are in Insite... but a lot of them are obscure in the programming, and you have to know exactly where to look to find them. Most these so-called delete shops never even heard of most of this stuffs, nonetheless could find much of any of it in the programming. That is how truly clueless they really are.

After taking a hard look at what is active, it is clear that some if not all of what your considering "weak" may simply be some of these limiters getting in the way of performance... all at the saving of fuel, like a mega-fleet-spec'd programmed truck would be. Remove most of them and you will see your performance go up, but it will also cost you more fuel to get it there. Need to keep that in mind.. nothing in the avenue of "increased performance" is free... it always costs you more fuel to get better performance.

How can someone know what they want turned on or off if they have no clue what is actually in the programming?.

I thought I would list them all here just for reference and for conversation purposes.

The official MM (non-public) versions of the demandate program overlays for the CM2350, and for the X15, (version 2021c or higher) turns all 28 of these features to "Inactive" and/or to "Max Performance" as their new defaults. Most truck owners when asked, want all this stuff turned off and would rather have the response and performance increases. It puts efficiency and performance back in the hands of the driver via their right foot and driving by their boost gauge... like on older model engines that did not have these features.

When they are all off, it is noticeable right away, even without any actual power/torque increases. At the same time however, for those people who tend to pushing their accelerator pedal harshly, instead of gently, they all usually complain that fuel mileage fell off a bit. - This is because it takes more fuel to get better performance out of any engine, it is simple physics.
