As I also explained to Phill, I have no doubt you can design a device capable of sending out the pulses and get that part exactly right. What I am doubting is the interference will go down exactly as planned. Because you don't want readings above 100kg/h. You don't want suspiciously low readings either. The reading have to correspond with where you are on the track. The fuel flow sensor is not developed for outside EM control (again, the other side is that the shielding will not be exactly great either).
I fear i am finally making sense of our misunderstanding Turbo:
If i (now) understand you correctly, you are suggesting an interference device that manipulates the readings in a way it can hit an exact range, that is very specific, not too high, not too low and thus argued that that required level of precision is far fetched.
I completely agree.
But i dont think this would be necessary. If *i* were to build such a device, i’d simply find away to make the readings produce an error result.
E.g. disturb so high, that the sensor will not get a reading for that specific instance/interval. Think of it of a sensor that can only measure up to a certain specified threshold. Everything above and the reading fails.
In a whole batch of millions of readings, this might not actually be all that suspicious if the data is smoothed and across the smoothing period is within the limits that the FIA confine. In fact, they might not even see it in their logs.
Think of it as a temperature sensor that can measure between -20 deg and +60. Below and above, the sensor will just produce a NULL value (or NaN or whatever). A program developed to make sense of this data will simply ignore that gap and smooth it out. To some degree, i’d expect a fuel sensor or any other sensor to do the same. The last thing you’d want, is to be alarmed by a small percentage of erroneous readings/gaps if it’s absolutely normal.
Obviously, if you’d do it often enough (e.g. throughout the season, on slow laps as well as fast ones), it might just be shrugged off as a regularity. Well, right until then when a competitor comes out with a proof-of-concept of a method/device that does exactly that.
