SpitFire Tuning Performance Chip

An in depth review of the SpitFire Tuning Performance Chip

This is a profound review and analysis of SpitFire Tuning Performance Chip made by SpitFire Tuning. These Performance Chips were purchased on eBay from seller spitfire_tuning. A direct link to the eBay store page can be found here:  https://www.ebay.com/str/spitfiretuning Let’s take a look:

Company Profile

The manufacturer is a company called SpitFire Tuning.

Cost

The cost on ebay at the time of this review varies, from $54.99 up to $79.99. A fairly decent price versus options available providing if claims are real. 

Product Appearance

The OBD performance module comes as shown above. We purchased one of these performance chips from SpitFire Tuning via eBay for testing.

Internal Analysis

After removing the cover of the module, we immediately noticed there was much more to the circuit board than just idle leds.

SpitFire Tuning Performance Chip Internal View and Observation

As for the claims, many products claim to do a lot of things, but do they really work?

We first stripped it all the way down to the connection points to the OBD2 port and we can see that all 16 pins are utilized. This is a great first sign, this tells us that it is for use in more than just one specific region of vehicles.

Data Link Connector (Vehicle OBDII Port)

The  IC has a JDM-USA Rev. 6.0 label on it. After doing several tests such as Program Memory type, CAN protocol, Program Max Memory Size, and Max CPU Speed and after all test have been made, we determined that the Chip installed is a JDM/Microchip version of the PIC16F59 with improved Programming Memory to 24KB and CAN Bus support verified through our lab tests. We have seen this relabeling from Microchip in other computer related parts such as video cards.

SpitFire Tuning Performance Chip Closer Look Into Processor

Time for a look inside the brain of the chip:

A look inside the processor of the SpitFire Tuning Performance Chip

It has a 4 mhz Resonator which is more accurate than the lower cost internal oscillators found on other performance chips so it cannot be another light scam chip.  It also shows in consistency for having the space utilized for a fully functioning program as well as a processor speed to make split second adjustments in real time applications.

Understanding OBD Protocols

http://www.pfdiagnose.com/FAQ1.html

From this chart, we see the following protocols and which pins must be present for them to be used:

CAN – 4, 6, 14, 16

PWM -2, 4, 5, 10, 16

VPW – 2, 4, 5, 16

ISO – 4, 5, 7, 16

So we can conclude from this that the SpitFire Tuning Performance Chip:

HAS all OBD connections to the CAN protocol

HAS all OBD connections for the PWM protocol

HAS all OBD connections for the ISO protocol

HAS all OBD connections for the VPW protocol

From these connections, the SpitFire Tuning Performance Chip does have the capability to interface to any of these protocols. According to the product information, the company claims it is custom programmed for use with only one vehicle. Therefore each chip must be reprogrammed if you want to use in a different vehicle than you originally purchase for (although that is true of all custom programmed chips).

Operation

We connected the chip to our same test vehicle 2016 BMW 530i 3.0L L6 as instructed and the lights came on as expected.

For about 1 week we drove only a few miles and did notice a definite improvement in throttle response and pick up power. In addition, the idle and overall handling of the engine did seem to be smoother. To be honest, we were rather impressed with the performance changes. We tested in a large run and noticed we had gained almost 4MPG on fuel economy.

Analysis

It is clear from our analysis so far that the SpitFire Tuning Performance Chip is capable of delivering real gains and is a good choice for those seeking a general tuning solution. We were impressed with the overall construction, ease of use, and performance gains that came is such a little device. And what is even more impressive is that this was a product that could produce such gains for such a little cost.

Conclusion

In many ways the performance chip of this company is very similar to that of the DragonFire performance chips we have reviewed, they both have the circuitry capabilities to perform and the programs (although vary in some ways from each other) deliver some very decent gains.

We can say with full confidence that this performance chip is an ideal buy in the automotive accessory and performance market.

  1. Thank you for your non partisan reviews. You saved me a lot of aggravation and wasted money. I stumbled upon this site while looking for reviews of one of those POS chips sold on ebay and you confirmed my suspicions. The chip I was looking at is nothing but a big scam and offers no real performance or fuel gains whatsoever. Keep up the good work

    1. We are happy to help. We are people just like you that are looking for honest real products and not scams, that is what got us started here.

  2. Just installed mine today , 2015 Ford F150 3.5 EcoBoost (96875miles). I will keep track and will do a write-up in a couple of weeks and see if there’s any changes. FYI, I have a Injen double cold air filter , 34′ inch tires with 2″ leveling kit and Flowmaster dual exhaust system. I will also add Rev9 intercooler sometime within the next week or so and will install SOS ignition coils. Can’t wait for the results.
    Thanks again for your honest review..

  3. I gianed 1 mpg and a slight increase in hp and throttle response much better than the cheap nitro cheap on ebay

    1. Actually yes, the way they designed their chip is that of literally a plug and play device. It provides the benefits of performance while plugged in and then the vehicle is stock when unplugged. When asked the reasoning behind this set up they explained that people with warranties on their vehicles or need to smog their vehicles will not be able to do so under your conventional performance chips, so their plug and play design allows the benefits of a performance chip and you can unplug it when taking it for smog or warranty and it will go back to original settings and no trace of being installed after which you can plug it right back in when done and it resumes it’s programming.

  4. Just ordered the spitfire chip for my 98 ranger 4×4 4.0 can’t wait to see how much of a gain i get. Super stoked to know it actually works thanks guys.

  5. I just purchased for my 2015 VW Beetle R-Line Convertible 2.0 TSI and it really fine tuned the car. I’ve driven it for 2 days and I am very satisfied. Shifting is a lot smoother, and I feel the HP as soon as I press the gas….no more lagging! Next is to measure the MPG. So far, very satisfied with the performance chip!

    1. That’s great news! We encourage people to share their experiences ( be it good or bad) about the performance chips they buy to further help the performance enthusiasts out there make a more informed purchase. Thank you for your information.
