Difference Between Different Firmware of Check Engine Code Reader

Fiberall provide 1.5 version and 2.1 version firmware for the bluetooth engine code reader. FA-V01L2M can be with both these two version firmware. So what’s the difference between these two version?

1, They supports different communication protocols. 1.5 version supports 9 protocols, but 2.1 version supports 7 protocols only. 2.1 version does not support SAE J1850 PWM (41.6Kbaud) and SAE J1850 VPW (10.4Kbaud). It means that 2.1 version cannot work on bus.

2, They are with different master chip. 1.5 version check engine light code reader is with PICI8F25K80 master chip. But master chip of 2.1 version is bonding. PICI8F25K80 master chip is imported and bonding chip is our own solution.

3, Their cost is different. The imported chip is with higher cost, and cost of bonding chip is lower. So the 2.1 version check engine code reader is cheaper than the 1.5 version.

4, They have difference on performance. The 1.5 version bluetooth car code reader is with more stable performance. 2.1 version always can work normally. But its stability and ability to resist external interference may be poor than 1.5 version.

5, It is not easy to control cost and lead time of imported chip. It is always affected by the supplier. The price is not stable and the arrival is not on time sometimes . But is it easy to control both cost and lead time of bonding chip since is it our own solution.
