First - this isn't falling on deaf ears. Rather, those who offer advice - as is what I've asked for - aren't listening to what I want to achieve.kudos lowqcab and a few others for your attempts at clarity, it seems to fall on deaf ears.
Again, for those who refuse to listen to what I'm asking for - "Accuracy doesn't matter". As for the "Slow" response time - didn't look that way on the scope. When I puffed into the pierced hole, the gauge responded nearly instantaneously. And yes, I know it kills the accuracy of the sensor, but - and yes, I'm going to say it again, ACCURACY DOESN'T MATTER TO THIS PROJECT.Puncturing the rear of the map sensor effectively kills any accuracy it ever had. map sensor response time is slow which is why most efi systems went with maf. NAPA is wrong, a map sensor does NOT measure the airflow into an engine, it measures pressure on the absolute scale and does so slowly.
Perhaps so, but it also requires one to look away from the roadway, which is - to quote your final word - "Stupid".the best option for reliable data is a scan tool that can display instantaneous fuel consumption.
Awe geez! I'm not looking to build the "Perfect" experiment. You called it a toy. OK, perhaps so. But children play with toys all the time and sometimes they learn something in the process. For a middle school science project my son wanted to show how you could measure differing variations in light intensity and material reflectivity. It was his idea. I helped him with an oscillator that responded to the amount of light the sensor took in. Was it accurate? Nope. But the entire class didn't need to get out of their chairs and come to see a small meter (d'arsenal movement). The whole class could HEAR the change in light level as he pointed it at different materials to see how they reflected light. Did it tell them How Much light was reflected? No. It DID, however, give an audible change in tone when something by comparison to something else affected the tone. Toy? Yes. And no. He learned something, and so did the whole class. He got an award for his project. When asked, he admitted that I designed and built the circuit; which was beyond his young ability, but the project was HIS sole idea. I only recommended that instead of using a light meter, which he could have bought - but then what would he have learned - I recommended an audio tone so that everyone could hear the reaction.the entire experiment is flawed, however, since the required distance to the vehicle in front necessitates tailgating which is dangerous, illegal and stupid.
