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:
The manufacturer is a company called SpitFire Tuning.
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.
The OBD performance module comes as shown above. We purchased one of these performance chips from SpitFire Tuning via eBay for testing.
After removing the cover of the module, we immediately noticed there was much more to the circuit board than just idle leds.
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.
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.
Time for a look inside the brain of the 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
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).
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.
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.
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.
