Firstly apologies I hadn't realised how poorly worded that article was when orginally posting it. This is the orginally article it stemmed from; https://www.msn.com/en-au/sport/motorsp ... cUbs7Hw1-w
I would also like to make it clear I did not write either article.

I'm a little perplexed, I've read an article by Willem Toet on his LinkdIn feed outlining how a traction control system might have worked on a 1994 F1 car......he seemed quite familiar with such a system and how it might have worked within the ECU constraints of the time.....No prizes for guessing where he was working in 1994.
That Linkedin article is dated November 2015. Willem Toet has since changed his opinion from that to the Left Foot Braking theory in December 2017. I know because I worked with him on something which I am unable to mention within this thread (but you might be able to guess what). Whatsmore Willem was happy to be quoted as saying: "I think it (what Senna heard at Aida 1994) was the use of left foot braking combined with the throttle which would have made the strange noise. There won't have been any engine cutting at all in those circumstances because the engine will not have been accelerating fast (with brakes applied as well) but it would have been strange to hear the engine working in those places on the track. That's what I believe is the most likely scenario."
Mark Blundell, a Tyrrell F1 Driver that season and like Senna was also taken out at that first corner in Aida. Whilst Blundell didn’t recall any strange sounds on Schumacher’s Benetton himself when walking back to the pits that day, he believes it was common knowledge their engine note was different. When asked whether the sound could have been left foot braking, Blundell responded “in terms of your description on what the input, outputs and benefits that would all make a lot of sense. Left foot braking was something that became a trend at that stage again, I was probably in the minority because I didn’t left foot brake, I was a conventional right foot braker and I think Rubens (Barrichello) was like me for quite a long time...It (left foot braking) would have made a different sound in that it would have had RPM carried into a corner, but I don’t think that would have made a sound like traction control.”
“When I was at Williams (as a test driver in 1991) I can remember driving around Imola where I had raced for Brabham the previous weekend. The Brabham didn’t have a blown diffuser, whereas the Williams did and it was just an unbelievable difference! When you got on the throttle (in the Williams) the thing would just suck down at the rear and just drive you off the corner. As such you would be able to crank a lot more front wing in and get a lot more aero on the car and the grip level was sensational…Left Foot Braking became an art and a trend was something you could only do if you had confidence.”
Frank Dernie, Benetton’s Chief Engineer in 1994, gives his view on Aida. “I am not sure what he (Senna) might have heard. Certainly, Schumacher left foot braked and certainly, Cosworth never permitted an engine map with any sort of torque manipulation in it, even when it was legal. My view is that Senna was searching for a reason why the Benetton had so much better traction than Williams, which I am sure was aero, and wrongly plumped for traction control. Once the great Senna had given his opinion it was taken as gospel by many, even though it was just speculation."
Similarly Christian Silk, who was race engineer to the second Benetton drivers throughout 1994 adds “Possibly Jos was too new and just learning the ropes of the B194, to be worrying about the intricacies of the Left Foot Braking and the Exhaust Blown Diffuser (at Aida 1994). Also at the start of 1994 no-one knew how good Schumacher was, hence the reason Benetton kept changing their second driver that season.” Silk also believes Schumacher’s driving style helped with pitch sensitivity, stability of the car, and tyre pressures, whereas his various teammates’ lack of confidence within the car induced more nervousness.
Let me explain why Willem Toet has changed his mind on this issue (which is a quality I hugely respect…indeed my motto is: “there is no point having a mind unless you are willing to change it”). Because in that Linkedin article you referred to he said:
“…A good driver would use the system to learn how to apply the throttle. Driving flat out everywhere would be fine except that it wasted fuel and made a more detectable sound.
So based on the bolded text Verstappen’s car should have been making the funny noises at Aida, given the Dutchman was a lesser driver than Schumacher? Nevertheless, I am open to the possibility it could have been this combined with the previous theory which Senna mistook for an illegal device.
I wish I could explain more than this, but I don't want to infridge the self-promotion rule. So I would say just do a bit of digging online into this yourself & see what you find
