BLO 86-87 esc module

[87-TURBO-T]

I have a BLO code spark control module for sale. Good working condition. $40 shipped

Weren't the 86 and 87 ESC modules different?

 

[87-TURBO-T]

They had different codes. This was off a 86. From my experience the 86-87 are interchangeable.

HKP which is 87 is just alittle more sensitive. Either will work.

The only difference between the BLO and HKP ESC modules is the number of poles in the low pass filter section. With the BLO module being a 4-pole, while the HKP module being a 2-pole.

This makes the BLO module more discriminating between real and false knock. Going to 2-pole filters was a cost saving move.
