Here is an explanation of what is happening with my blitz icolor (i hope someone can help):
The speed sensor wire for the blitz controller is soldered to the correct wire on the ecu harness (about 4” from the actual ecu itself) as I have triple checked the wiring diagram, when I drive the car it reads correctly up until about 50km/h…after this the number gets stuck then when get to about 75km/h the speed sensor almost doubles to about 135km/h, the display goes erratic – then when I slow down it sticks on this displayed number of 135km/h until I get down to below 50km/h…from here it starts to count correctly on deceleration.
The car is a gtr r32 with an apexi power fc fitted. The hand controller on the power fc reads correctly on the speed setting, my previous apexi avcr also read correctly with the speed setting & I can also verify that the speed sensor wire used for the apexi avcr is the same as the wire that has been tapped into for my blitz icolor.
I tried calibration menu, my car is pulse 2 which gives me the above results. I also tried pulse 4, 8 & 16 which are not compatible for my car. I then tried the “keep to 40km/h then enter” method which is the manual calibration & also recommended & with the same above result.
does anyone have any ideas or thoughts? i have emailed blitz direct but no response as yet...to me it sounds like some type of electronic interference of some sort but that is just a stab in the dark.
