Thank you for providing a clear explanation of the intended use of the target AFR table! Spending a significant amount of time on the video-sharing platform YouTube and an introduction to the concept of Electronic Fuel Injection (EFI). The HP academy course has not provided a good explanation of the topic. I need to invest in a professional tuning session for my automobile on a dynamometer, but where is the enjoyment in that!

The table is quite coarse, I concur. Despite the many spikes on the table, the driving experience is unexpectedly smooth. However, I fully concur that the VE table requires significant more effort to get a smoother performance. Thank you for the thoroughness of your answer and the VE table you provided. I will not replicate your VE table since I acknowledge that each engine and configuration is unique, which might impact the engine's efficiency. My understanding is that I need to get some logs and manually adjust my VE (Volumetric Efficiency) in order to achieve my desired goal Air-Fuel Ratios (AFR). Striving to maintain a consistent table without fluctuations of 20 units, as it now has. Make sure that this table is positioned in close proximity to my objectives, and then activate the closed loop function, completely disregarding the VE auto adjustment capability. I am somewhat perplexed by the use of target Air-Fuel Ratio (AFR) vs the Volumetric Efficiency (VE) chart. It seems that you are neglecting the target table while configuring the VE table. However, the target AFR table is used in determining the amount of fuel to inject, with VE also being taken into account. A report on the underlying reason for the sudden increase in VE. I adjusted the fuel mixture of the vehicle to a higher richness level during my commute to work, specifically at a boost level of 11.5. This allowed me to optimise the performance by correcting the fuel mixture in the areas where it was too rich at 5000rpm. As a result, I was able to consistently achieve my desired performance goals, which was not the case while aiming a richness level of 12. Tonight, I will focus on improving the overall smoothness of the table. Afterwards, I will implement closed loop control on the ECU, allowing for tiny real-time modifications. Would a range of 5-10% be suitable for this purpose?

Greetings, I have been fine-tuning the performance of my supercharged 1.6 engine on the road. I am using a donor engine with a fully undisclosed past, save for the fact that it had oil when I purchased it. The vehicle is maintaining a consistent and stable performance in terms of reaching my Air-Fuel Ratio (AFR) objectives. However, the autotune feature is persistently attempting to increase the amount of fuel at 5000rpm and 140kpa. I am genuinely perplexed over the cause of this. Regardless of the desired air-fuel ratio (AFR) or ignition timing, I failed to see this anomaly on my previous engine. I have experimented with ignition timing ranging from 11.8 to 12.3, as well as anywhere between 13.5 and 17 degrees, in these specific ranges. Autotune continues to inject more fuel in order to achieve the desired air-fuel ratio (AFR). Occasionally, a run may result in a rich mixture, leading me to suspect the presence of an intermittent issue. The car is equipped with a coil on plug system, utilising BK7RE spark plugs with a gap of 0.8mm and 0.6mm. No noticeable change was seen between the two gap sizes. The problem persists when utilising the conventional ignition system and BK6RE spark plugs with a 1mm gap. The injectors are EV14 with a capacity of 550cc. The intake temperatures range from 20 to 40 degrees Celsius, which is within a reasonable and safe range. I am open to any and all advise to improve the smoothness of this VE table. I am willing to test any suggestions. I have received suggestions that the issue may be a misfire, but I have conducted tests on several ignition systems, plugs, and gaps, and I believe I have eliminated that possibility. What is the procedure for monitoring fuel pressure while in motion? The user's text is incomplete.The automobile has excellent performance and operates smoothly without any problems at higher revolutions per minute (rpm).

I feel the same way. I have had two Karchers, both of which exhibited excessive vibration and noise, both of which experienced leakage from the beginning resulting in intermittent pulsation, and both of which ultimately failed with smoke and sparks emerging from the motor vents. Subsequently, I purchased a Nilfisk, and the disparity in performance is very distinct. The machine seems to be well-designed and has outlasted both Karchers combined. Purchasing a £15 adaptor from eBay allows me to use the extra attachments I purchased for the Karcher with the Nilfisk.

The engine had a progressive decrease in speed despite operating for less than 3 minutes and being fully serviced in January, which included the replacement of all lubricants and the installation of new turbos 18 months earlier.

While driving at around 35 miles per hour for little more than 5 minutes, a message appeared on the dashboard indicating "Engine Failure," causing the automobile to suddenly stop moving. I am now awaiting the arrival of a rescue vehicle since my car is not starting, despite having a fully functional battery.The car had its most recent comprehensive service and MOT in January, and just last week, new airbags and front struts were installed.I inspected the oil five minutes before to this occurrence. Does anybody have any suggestions or insights before RR takes advantage of me financially once more?

I myself own both the Mazda3 in red and the CX-30 in the same blue hue as yours, which I find to be a more aesthetically pleasing colour.

I encountered the same problem. The price mentioned here was far more than that. Regarding the replacement, Audi said that they would cover the cost for one item, not two, since one of them had a little crack (which seems dubious to me). I proceeded on as I wanted to get my automobile. Now, they should have incurred payment for both items, even if only one was impacted. What is the reason for this? Due to the change in component number, the new one has a distinct reverse light. Consequently, the automobile would seem peculiar with dissimilar tail lights.

Hopefully, that information may be beneficial to you, my friend. 🙂

Thank you for sharing your expertise and thoughtful analysis. It's gratifying to know that yours is functioning. Similar to any novel model during its first year, some models may encounter difficulties. At now, we anticipate a reduction in problematic locations; nevertheless, the outcome remains uncertain. Meanwhile, stay connected with us here and feel free to provide feedback, both positive and negative.

This is the reason why the negative is first disconnected and then reconnected.

Disturbing......

What was the cause of such occurrence?...the voltage is merely 12 volts, which is insufficient to cause an electric shock. Applying pressure to each terminal will not elicit any sensation, unless you are manipulating a live ignition coil, which produces a little stinging sensation owing to the presence of several thousand volts. If one were to make contact with a live terminal at the location where it was shorting to the earthed body, it is possible that experiencing pain may arise as a result of the heat created.

Accomplished it perfectly! 😁

As a mature individual with a youthful spirit, I am choosing to align myself with the majority in this situation. Strive for simplicity and authenticity, replacing any elements that detract from the overall quality (such as alloy centre caps, for instance), and focus on achieving the highest possible level for the painting. Black vehicles with a glossy and attractive paint finish seem quite impressive. Have a pleasurable experience!

Thank you for sharing your expertise and providing the information.

That pricing is reasonable given the substantial amount of effort needed. However, I now have 99,000 miles on my vehicle and have previously had two maintenance, with the most recent one being 23 months ago. Therefore, I want to wait for at least another year before getting another service. Will they agree to do just a stand-alone service on the gearbox, without any other tasks?

Greetings, everyone. My 2013 S204 with 7G+ gearbox has already reached 10 years of age and I am responsible for its service. There is a discrepancy between the Mr Car Assyst plus and Mercedes Myservice web page on the kind of service required. I am tempted to choose the Mercedes service website. Regardless, the vehicle requires a B9 service which includes the installation of an air filter, fuel filter, and a brake fluid change. Interestingly, it also need an Auto Trans service. I am sceptical since the second gear box of the vehicle was serviced two years ago (the service before the most recent one) and it was just about 22,000 miles ago. Undoubtedly, it is not yet due. I believed that the requirement was either 50,000 miles or 5 years, whichever occurs first. So far, it has only been requested twice in over a decade. Can anybody verify? I will personally handle the remaining tasks of the service and use the oil extractor to take advantage of the conveniently located top mounted oil filter, ensuring a quick and clean process.

If you visit the Blackvue Official Outlet, you may get the 2-channel version of the 590X for the price of the 1-channel version in the Amazon link you provided. The item is 'refurbished,' indicating that it is often an ex-demo product. I have purchased two items from this supplier, and they have been identical to new.

The user's text bears resemblance to my own. At first, the recurrence of the hatch malfunction was sporadic, but it rapidly escalated to a near-consistent frequency at each instance of hatch opening.

The 2022 Turbo Premium Plus vehicle has an audible popping noise upon the activation of the hatch release mechanism. I have scheduled a meeting with my automotive dealership for tomorrow am. The auditory phenomenon occurs consistently with each instance of opening, hence necessitating immediate auditory perception by the individuals involved. The user expresses gratitude for the assistance provided.

The vehicle in question is expected to exhibit reduced speed due to its increased weight, as previously mentioned.

The automobile in question represents the most unsatisfactory ownership experience I have encountered so far.It is evident that you, organman, were never an owner of a Chevrolet Vega.
