Yet another of these universal OBD (On Board Diagnostic) port engine remappers that claim to analyse your driving and then rewrite key parameters in your ECU (Engine/Electronic Control Unit) to offer greater power with less fuel.
I bought this one because it showed a picture of the PCB in the listing, showing that it uses an eight pin microcontroller and appears to have actual connections to the canbus network on the OBD port.
The power pin placement on the microcontroller is odd. I don't immediately recall a similar pin layout. It would be interesting to know if it's a standard device. It's not a Padauk chip as far as I can see.
In standby the module enters a passive mode at 9mA where it pulses the communication LED. When activity is detected on the canbus network it directly affects the green LED and after a short time triggers the power LED to come on and the communication LED to start flickering. If the canbus becomes inactive the unit goes into standby mode after about a minute.
Because the chip has a direct connection to the canbus network it is possible for a malfunction to take out the network in your vehicle and cause lots of random problems when the other devices on that network are unable to respond to the ECU.
The unit is fake. It's a placebo. To store suitable details for every single car since 1996 it would need to be able to identify models if it could read the VIN (Vehicle Identification Number) code and then have a database of parameters that could be adjusted with a suitable tuning algorithm for every model. That's not viable for a little 8 pin chip and most cars don't have the facility to make significant changes to the ECU tuning settings via the OBD port.

I‘ve actually once DoS‘ed my own car while working on the OBD port. I‘ve tried creating my own fuel economy gauge and because I sent the commands too fast my car freaked out. The running engine just simply turned off and it gave me a few warning lights to enjoy. Stopped the script, unplugged the cable, turned off the car and restarted it and everything was back to normal. But that was certainly a shock moment.

Hi Clive, all the way through the 1960s '70s and into the 80s, there was a much cheaper way to make your car go faster.... You bought a roll of "Pinstripe" tape and stuck along both sides of your car - guaranteed to increase your top speed by up to ten miles per hour. Of course, if you only put it on one side of the car, it would go faster on the outbound leg of your journey, or on the other side, it would go faster on the inbound leg. If you wanted rally performance, you bought a much wider tape and stuck it all along the top of the bonnet, roof and boot lid. better still, stick some vinyl numbers on your front doors! These all worked equally well. All you had to do was to believe in unicorns and pixie dust.

I bought one of these as a generic elm327 unit, for something like $13 US...I was testing some software and wanted a poorly rated dongle to see if I could make it work and at the same time, make my software more robust. But, in fact, the thing failed electrically. It went bad and did cause issues in my car that required more than one cycle of the key. You are 100% correct - as usual.

I don’t know for certain, but I strongly suspect they measure throttle response (possibly) and use an accelerometer (almost certainly) and possibly mileage driven to determine how aggressively one accelerates, brakes, and corners over a period of time as well as how much driving you do over a month - essentially testing for aggressive driving. These days they may as well use a smartphone app to record the same.

When I worked on Cars. We did sell Power Programmers for Trucks and SUV's. But they actually did something. They were in the $300-$500 range. It was a much larger Box. It would actually save a copy of your program in the Programmer so that you could restore it back to factory default. Then you can go through the settings to change the things you want to do. But generally, to get the best performance, you would have to set it to Premium Fuel. At that point, you would have to fill up using Premium Fuel ONLY. No more Regular or Mid-range. They actually did do what they were supposed to do. Nothing like this little toy thing that is shown here. It does a whole lot of nothing.

I really like this theory. If so, the Can Bus is connected to I/O pins at 5 and 6. LEDs are connected to I/O lines at 3, 7 and 8. This microcontroller has on-board clock, RAM and a big EPROM so it is fully self-contained. This means that it could easily be talking to the CAN Bus and could actually be doing something. The next thing would be to analyze the CAN traffic to see what is happening. Good find.

It can run on the internal RC oscillator. Some have trimming registers for tuning, as well as PLL's for multiplying the clock. However you are correct that this micro is unlikely to have a CAN transceiver. So successfully communicating on the CAN bus would be difficult. I will not say impossible, as there is some trickery that could make it possible.

Also, if you have an accident with one of these left plugged in and have to get towed/mechanic, I'd suspect your insurer might take it as a reason to refuse/restrict cover (even though it's doing zilch). Most insurers treat remaps/ECUs as mods in the UK iirc, so will bump your premium up a good bit if ones installed (despite them actually being fairly innocuous, and even practical for some models). Not sure if they routinely check for it though on vehicles involved in accidents, but I'm pretty sure a chunk device plugged into the OBD II would be noticed given its ubiquitous use in garages.

I bought one of these and mine works like a charm, I am getting almost 5 more miles per gallon on my 2005 Tahoe, I did have to wrap in in aluminum foil first, I think it was picking up too much interference from my cell phone, but once I did that it started really working, I have one on all of my cars including my wife's jeep, too soon to say how well it is working on that.

Only thing i have found that works , and its on diesels only i think is a chip box you install under the bonnet , connects to the common fuel rail plug then back into the loom. I think it fools the ECU into thinking the air temp is colder or something, maybe a few other things as well . They cost anywhere from £80to £100 plus but do work . I had one fitted to an x-type jaguar and there was a very noticeable difference in throttle response and acceleration , it was a little bit of trial and error to choose the correct setting for it , anywhere between 1 and 9 . 5 was best for general everyday driving , going higher and giving it a lot of wellie for a while would bring up the engine management light but no damage caused

Psychosomatic me thinks...on the other hand the superchips bluefin I used on my ford makes a hell of a difference ...but it does cost ~£330-£500 depending on the car model.

That's a cute little "blinkenlights" unit. If anyone watched SMA's video on the Dodge Caravan that reset the dashboard and set the wipers running whenever the power sliding doors operated... That's what happens when your CANBUS gets tampered with. For best performance from a vehicle (acceleration, braking, fuel economy) the best thing ANYONE can do is keep current on scheduled maintenance. Regular oil changes, tune ups, and good quality fuel (from a major supplier) in addition to driving mildly (gentle acceleration/braking patterns) and not carrying more cargo than is necessary will be far more effective than any silly OBD-II dongle quackery can ever be. One-size-fits-all devices cannot take into account all of the variables than an ECM handles - each specific engine has its own mapping for air/fuel ratios, injector pulse timing, etc etc etc. Even the same exact engine used across multiple vehicles will have completely different programming. Any effect these modules have on a car is a placebo at best.

My performance booster chip came from The Royal Palace of Nigeria... it has an official seal of authenticity and only cost $65 per month. Not sure how much horse power it added, but customer support said they can double my gain any time I choose, by sending another $100 per month. It’s a bit expensive, but I could sure use the extra power.

Loading components on both sides is obviously more expensive... You have to stop bits falling off the first side when reflowing the second. The 7805 regulator should have a small cap on the input for stability. The choice of regulator package may be due to power dissipation to get vehicle "12V" down to 5V. As much as 16V is often seen on vehicle power supply rails.... with automotive rated components rated to deal with 60V load dump transients. Such transients occur when e.g a "mechanic" disconnects the battery while the alternator is trying to charge it.

I think I know what these units do - I too bought one out of curiosity, at a time when I had a recurring ECU error caused by a faulty Crankshaft Sensor. I was keeping an eye on the situation with an iCarSoft OBD Diagnostic Tool until the new sensor arrived, but I noticed that with the eBay unit connected, every couple of days the fault would be cleared briefly, before returning again. With or without the unit attached, there was a noticeable drop in performance when the fault was logged by the ECU, so is it possible that the eBay Unit just occasionally sends a 'clear all faults' code? Maybe the 'MCU' is a Pic chip of some kind? Reminds me of the one's they used to use for modding game consoles back in the day :) so just enough guts to send a clear code and the required confirmation code, based on elapsed time. I don't have the equipment to see exactly what happens, but I agree that there's no way these devices could re-program ECU Fuel Trims.
