Fuel Pro Max Chip

This is a review and analysis of the Fuel Pro Max chip module. If you are looking for a REAL Fuel Pro Max chip review, then this is for you! What is this product and what does it do? Let’s take a closer look:

Company Profile

The manufacturer is an unknown company on ebay with the username ‘x.factor.performance’. It did not appear that they had a website at the time of this review. The product case looks almost identical to the Nitro OBD light blinker scam, so we are already especially suspicious of this product. Let’s see what it actually does.

Cost

The cost at the time of this review on ebay for the Fuel Pro Max chip was $34.99 USD. This price is very low to be a genuine performance chip. The seller’s other items and feedback do not help – they also sell Nitro OBD scam chips. 

Product Appearance

The module comes in the all too familiar yellow case shown above.  Just like most scam chips, the seller claims it fits numerous year vehicles – so it is obviously not custom programmed for a specific vehicle:

Another suspicious factor is the outrageous HP claims which often also accompany fake scam chips:

Really? A fuel saver chip that provides gains of ‘up to 100HP and 6MPG’? Also, it is a Stage 2 fuel saver chip? That is a first. This is definitely a scam. The question is – does it do anything at all?

Internal Analysis

We purchased one of these modules from eBay and examined the inside of the module:

Our suspicions were immediately confirmed when we removed the yellow plastic top of the module. What we find underneath is the all too familiar circuit board shown above. It is identical to that of the previous Nitro OBD light blinker scams we reviewed previously. The red circle shows where the surface mount IC is located on the rear side of the PCB to prevent identification.

If you were with us for the NitroOBD Performance Chip Scam, you will notice this familiar circuit board design immediately. The circuit board is built around this hidden IC chip on the rear of the circuit board, which is a STM8S003F3 IC. Right away we see a problem here, because if one pulls up the datasheet for the STM8S003F3 IC, we see from the manufacturer, ST, that this chip has a maximum program memory size of only 8KB:

Online searching shows that ECU maps for a vehicle will be at least 20KB in size or larger PER MAP! This is way too large for the STM8S003F3 IC to contain. So, if this is the case, there are no genuine vehicle maps onboard this module. What can be stored in such a small 8KB sized space then? It would be perfect for another fancy light blinker.

Operation

We connected the Fuel Pro Max chip as instructed to our test vehicle. We ran at least two tanks of gas with the module connected and noticed no improved power or fuel savings – just a blinking light show!

Another feature that confirms our suspicions was the fact that the lights blinked in an all too familiar pattern – exactly the same as the Nitro OBD scam chip did. It looks like our suspicions were correct.

Analysis

It is clear from our analysis so far that the Fuel Pro Max chip is not a performance chip or a fuel saver – it is simply just another Nitro OBD light blinker scam with a different design on the case. The circuit, like the numerous other light blinker scams, blinks to give the illusion of communicating with the vehicle ECU, but in fact it does nothing. We would not recommend it as the Nitro OBD scam chips have been known to set error codes as well as cause random issues on some vehicles. The blinking signal can appear as random data to the ECU and permanently cause damage in some cases.

Conclusion

From our research and review, it is our opinion that the Fuel Pro Max chip module is yet another of the numerous light blinker scams. It may also cause ECU damage, so we suggest avoiding it at all costs. You definitely want to pass on this one!
