Ls Knock Sensor Delete Pros And Cons

Its VERY tough when you get long tube headers, RRs, loud exhaust, etc to keep the knock sensor from picking up false knock. Diesel engines typically cool the exhaust gases generated, then recirculate them back into the system. Doing so could subject us to civil penalties and possible criminal liability. Ls knock sensor delete pros and cons full. An EGR delete can lead to a boost in performance. For later vehicles with E38, E67 and newer ECU's retaining the MAF when correctly tuned results in better drive ability, faster ECU timing processing at high engine speeds for increased performance and lower stable idle speeds.

The knocking sound at 1500 rpm is gone as well. I have run 94 octane on the street at WOT with no audible pinging and no signs on the plugs. While we will work on your vehicle, even if you have an EGR delete, we think they are a terrible idea. In addition to this the MAF used was relatively small in internal diameter and offered a restriction with only modest modifications, the removal of the MAF did not inhibit the performance of the ECU and did reduce the amount of restriction in the intake offered by the MAF sensor itself. Just curious, as that is what people here in Canada do. This system utilizes several unique features in an effort to maintain optimal flow for performance while minimizing turbulence that can cause engine management problems. Still getting the SES light even after taking the battery cable off for a while... What are the ultimate plans for your engine? The reality is that we see a lot of trucks with deleted EGR systems. Location: Manassas VA. Posts: 3, 197. Ls knock sensor delete pros and consumer. While rolling coal is not specifically illegal in Texas, the Clean Air Act of the United States prohibits it. I noticed the oil pressure gauge was buried over 80 and reached back to check the sensor.

Ls Knock Sensor Delete Pros And Cons

It is in this way timing advance can be added to make more power, in theory. My personal preference would be going GM equipment and have a custom harness done and ECU custom tuned as I think there is more reliability with the GM components compared to the CHINA made components that FiTech uses. Some vehicles experience more fuel consumption. It has been mentioned above that it plays an important role in keeping our environment healthy but having it removed also has some benefits. For decades ECU's have had codes that warn of a fault, as technology improves, and the ECU becomes more sophisticated these internal checks have become increasingly more accurate and reliant on sophisticated modelling within the ECU. Damage produced by knock can occur quickly and is irreversible (without rebuild). One for the highway, with it in, and one without for the track. That doesnt sound all that safe to me. He also has a store on ebay. My curious question for both of you would be, since you are running a LS motor, are you not better off using the complete system from GM such as the intake, injectors, sensors, ECU, etc? What is to come of vehicle tuning? Software tuning tools. It is costly because the materials used are also expensive such as palladium and platinum. Instead, it works with other systems in your truck. At lower engine speeds the ECU calculates the airflow and measure the airflow, it does this and determines the dynamic airflow, this is the most accurate airflow value as it uses the strengths of both methods. Taking away the protection the computer has built into it can only lead to further issues.

Step 5 – Remove the catalytic converter. Join Date: Sep 1999. I've never done any type of work on an LS1 before lol. This is inconvenient for you, sure, but it is also dangerous and costly to fix. That is my opinion, you can do whatever you like. The SF Air Box adds the benefits of a cold air intake to the outstanding performance of the SF Intake. Ls knock sensor delete pros and cons. This calculation takes processor time, GM switch off this calculation at high speed, typically above 4000 rpm. Instead of deleting your EGR, consider an aftermarket exhaust system. Please correct me wherever I am wrong and let me know exactly what a knock sensor does and why I would need it.

Ls Knock Sensor Delete Pros And Cons On A Ram Hemi

You can improve your fuel efficiency with an EGR delete. This reason must be acceptable and must also be documented. Beware the interceptor chip to tune your late model car, there may be unintended negative and expensive side effects for the small apparent gains achieved. EGR Delete (TBI) & Custom chips - Info/Links. The MAF requires no calculation as it is a sensor that measures Air flow, speed density is a calculation requiring manifold pressure, inlet air temperature and engine speed. I spent weeks getting the factory harness stripped of unneeded wires, lengthening some wires, shortening some wires (done both before and after the engine was installed). Within the General Help forums, part of the LSx Technical Help Section category; Hey guys... Anything before that would be "Pre-Detonation", or Pre ignition, or knock. In fact, the catalytic converter is considered to be one of the most expensive individual parts of a vehicle. A current model ECU will check the TPS in multiple ways.

These days it is everywhere, finding the truth has become nearly impossible. This is the time to be realistic, buy once and save. That's why some owners choose to just keep the valve instead of run with the delete kit. Most people think they can just add it to the tank and all will be fine... which is not the case... there are a lot of things that can create a situation where knock will be present. If the Interceptor chip is adding 10 degrees by moving the reference and the maximum timing the ECU can remove is 8 degrees then the engine may be running 2 degrees more timing as measured with a timing light however this is not what the ECU is outputting, the ECU does not know that its point of reference has been moved. Shutting off knock sensors???? Why. You may have heard that an EGR delete will improve performance. Be aware of the fuel you are going to run, E85 requires roughly 30% more fuel flow than Petrol under the same engine conditions. The engine will no longer have to work double time to produce the same energy when the converter is still in place.

I've heard changing the plugs can be a it's anything like when I changed the plugs on my Ram. If you want to remove it the legal way, you will have to follow some specific process. No one wants that, so it's important to have your knock sensor repaired when problems arise before the domino effect can begin. With it removed, you will get to experience a low-pitched, louder, and a more distinctive exhaust sound. Knock sensors are essential to the operation of your car because they guard against engine damage brought on by excessive air pressure brought on by the aforementioned air and fuel mixture. It is primarily open at low speeds or when idling.

In conclusion for early LS1 P01 ecu vehicles, the MAF is restrictive and offers little advantage. The impact the EPA crack down has had on tuning is to reduce the ability of US based tuning software to modify and delete emission controls. Tl dr: Not a good idea. You get black smoke from incomplete combustion because the excess fuel in the engine causes the black smoke. Step 4 – Detach the catalytic converter from the exhaust system. The cold air intake does typically get denser air than the stock intake. The maximum fuel required is a ratio of the maximum airflow achieved. If we do better as an industry and educate the consumers rather than bending to every request there is a greater likelihood the industry can continue to survive, with the advent of electric cars and much tighter OE vehicle security preventing ECU access we are already on borrowed time.

Even though GM components may be made in China, their quality is far superior. Just wondering if I can reach back there, remove the old connector from the sensor, splice a new one (along with a longer length of wire) onto the wire and reconnect it to the sensor without having to pull the whole manifold off I really don't wanna do that. This eliminates the "dead spots" experienced by other aftermarket intakes due to turbulence. I have a #70051 harness, Victor JR EFI High rise, Holley Elbow and TB. Using an aftermarket kit to delete it can lead to a bunch of problems. It's the one that is upside down). To answer your question, yes, the knock sensors are susceptible to issues. Next, quit hauling around junk in your truck. No one wants to think of additional running costs at the moment but if everyone pays their own small share relative to the level of additional pollution they make then maybe a compromise can be made.
