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. We purchased these performance chips on eBay from the seller spitfire_tuning. You can view and purchase their products here: https://www.ebay.com/str/spitfiretuning Let’s take a look:
SpitFire Tuning is the manufacturer.
The cost on ebay at the time of this review varies, from $54.99 up to $79.99 which is fairly decent price versus options available providing if claims are real.
The OBD performance module comes as shown. We purchased one of these performance chips from SpitFire Tuning via eBay for testing.
We removed the cover. And immediately we noticed there was much more to the circuit board.
Many products claim to do a lot of things, do they really work?
Stripping all the way down to the connection points to the OBD2 port we can see that the manufacturer utilized all 16 pins. This is a great first sign, this tells us that it is for use in multiple regions of vehicles.
The IC has a JDM-USA Rev. 6.0 label on it. We performed several tests such as Program Memory type, CAN protocol, Program Max Memory Size, and Max CPU Speed and after all tests 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. We have seen this relabeling from Microchip in other computer related parts.
Time for a look inside the brain of the chip:
It has a more accurate 4 mhz Resonator. Better quality over the lower cost internal oscillators found on other performance chips. It shows adequate space utilized for a fully functioning program. A processor speed to make split second adjustments in real time applications.
Understanding OBD Protocols
These pins must be present to function properly:
CAN – 4, 6, 14, 16
PWM -2, 4, 5, 10, 16
VPW – 2, 4, 5, 16
ISO – 4, 5, 7, 16
The SpitFire Tuning Performance Chip:
1 HAS all OBD connections to the CAN protocol
2 HAS all OBD connections for the PWM protocol
3 HAS all OBD connections for the ISO protocol
4 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 says they custom program the chips for use with only one vehicle. (That is true for all custom 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. The idle and handling of the engine is smoother. Very impressive performance gains. We tested in a large run and noticed we had gained almost 4MPG on fuel economy.
Our analysis: The SpitFire Tuning Performance Chip is capable of delivering real gains and is a good choice for those seeking a general tuning solution. The construction, ease of use, and performance is impressive. More impressive is that this was a product that could produce such gains for such a little cost.
This performance chip is very similar to the DragonFire performance chips. They both have the circuitry capabilities to perform. The programs 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.
