Why do mechanics buy multi-hundred dollar scan tools to communicate with the car when they could just make a scan tool with this chip for a few dollars and communicate just as well?

I’ve met a few people who absolutely swear by these things. When I was working as a mechanic, I had a handful of vehicles come in with dead batteries because these were plugged into the OBD2 port and drawing power. It might not kill the battery overnight, but some of them have relatively high power draw, and when that is drawing continuously for several days while the car sits (like when on vacation) it kills the battery. I had one customer in particular who refused to remove the stupid thing and instead wanted us to hardwire a battery charger to their vehicle so they could just plug it in when the vehicle was going to sit. I told them to get lost.

About 30 years ago or so, I had a mate who asked me if he could park his car in my garage while he went away on holiday. Just before we locked the garage, he opened the boot. When I asked why, he said it was to dry it out (don't ask me why). Anyway, 2 weeks into his vacation, he frantically calls me and said he just realised the light would have been on the whole time the boot was open. When I went to check, there was no light and the battery was completely flat. So I had to disconnect the battery and take it to a garage. It was too far gone so I ended up buying a new battery (which he wasn't happy about). So there's more than one way to drain your car battery without thinking. Leaving a door open would probably do the same. Note: You could have told him to unplug it when not in use. Or see an electronics guy to put an on/off switch in it. 😆

About fifty to sixty years ago, you could increase your car's performance simply by adding "Go Faster Stripes" down the sides of your car. For rally performance, you had the power performance stripes which were much wider and went over the roof! Much the same effect could be achieved by bolting on a pair of Cibie Oscars to your front bumper - Two pair, and you got turbo halogen power! Similarly, fitting a "drainpipe" exhaust was said to add an extra 7.568 mph in top gear. A few years ago, it was the "Turbo Waste Gate" but only if it made a ridiculous PING-PHWEE sound every time you changed gear! It's all in the mind, only these electronic gadgets are more plausible because it has a silicon chip inside it, and you can't see what it does, and therefore, no one can prove you wrong.🤦🔧🙎😊😁😁

I'd say that having the bottom end of the Intellectual Bell Curve wasting their cash on this would generally be a lot less destructive than shovelling it into the pockets of a scammer politician! 🙄👿

*Summary* *Video Introduction* - 0:00: Discusses Nitro OBD2 "Performance chip tuning box." - Explains how most engine control systems are locked by manufacturers. - Highlights that the majority of these chips are fake and rely on placebo effects. *Product Features* - 0:19: Version for diesel cars and one for gasoline cars. - 0:34: Claims to communicate with the engine management system to optimize fuel consumption and power. - 0:52: Comes with a two-year warranty. *How to Use* - 1:00: Instructions indicate where to find the diagnostic port in the car. - 1:13: Plugging the device into this port supposedly gives access to the engine management system. *Hardware Inspection* - 1:31: Speculates that it should contain a powerful processor if real. - 1:52: Discovers a small eight-pin chip, without any identifiers, inside the device. *Circuit Analysis* - 3:00: Takes picture of the circuit board to analyze it. - 3:10: Observes that commonly used networks for OBD2 connections are not connected. - 3:55: Identifies an LM358 chip, initially thought to be a 555 timer. *Circuit Functionality* - 5:03: Explains how the op-amp (LM358) is used to create an oscillator. - 5:38: Details the process of charging and discharging a capacitor to create the oscillation. *Deception Tactics* - Mentions the reset button's role in stalling people asking for refunds by making them think they are using the product incorrectly. *Conclusion* - Suggests that the unit is essentially fake, and highlights a 7mA continuous current draw that could drain the car battery over time. *Additional Remarks* - Clarifies that Temu is not a sponsor and comments on their business model. - Encourages support for the channel through coffee donations.

Love to see that you are still testing all of these useless OBD2 adapters

Good source for the conventor thats about it

These devices are like downloading more RAM for your home PC 🤣

So thankful it comes with a 2 year warranty. 😂 crazy people fall for this, circuit reminds me of one of my Mims books. These devices rank up there with the turbo encabulator.

If it were a wee bit bigger it would make a great wheel block for when you have to change a tire, wouldn’t plug that in, should be rebranded as Nitro Car Warranty Zapper. Clyde when you getting a logic analyser to do some in dept checks on these Sus chips. They got them for 5 quid and that module may be set to spy on us making you a hero.

This is gadget is almost getting into the territory of those free energy devices

My first thought was that it probably was an opamp flasher. I didn’t expect to be right on this one. Got to remember the ‘idiot tax’😂😂😂

I had a Tunit unit fitted to a Land Rover Discovery 3 2-7TDV6 and put it on a 4wheel rolling road to see how much improvement in power it gave,the result absolute zilch,no improvement at all. Tunit was contacted and they ask me to take it to their head office In Chorley,the removed it from the vehicle and took it inside a building and then refitted it and then went for a test drive,the result engine warning lights came on and still no improvement in performance,after a few seconds the engine went into limp mode,the man with me removed the unit and the engine cleared its faults and at that point I asked for a refund which they gave me,I had it properly remapped and couldn’t believe the difference in performance and fuel consumption,I again put it on a rolling road and the difference was unbelievable,about 35bhp more with great torque. These plug and play things are a con don’t waste your money.

If I were to build one of these, I'd put a bar graph LED display in, read the current speed from the CAN bus, and display that on the bar graph. That'd be 200% more convincing.

The sarcasm is killing me, lol. Nicely done.
