Re: hfs4 and megasquirt
 

started driving car again and trying to get the meth working right. im having a strange issue. every thing seems to be working as it should except my duty cycle signal seems like its not being read right i have signal and i get the blinking led on the board but when i test drive it with the IDC jumpered all i get is the S blinks then goes sold with rpm. i have thres all the way low and the i have the 1.5x gain linked. but im not getting trigger. also have it set to 100% injduty

Can you post a Hi-res picture of the top and bottom side of the Controller.
It seemed the red and green wire of the grey harness is reversed.

Thank you.

How does the megasquirt wired into the HFS4? Assuming you are using the grey harness?

Re: hfs4 and megasquirt
 

yes i am using the gray ECU harness. at this point i only have the red going to +12v inj pwr and the green is pulling signal from bank 1 INJ. i working on trying to get map signal output put its proving more difficult then expected.

Re: hfs4 and megasquirt
 

This should be straight forward. Are you using low impedance injectors?

Where does the red wire of the power connector taps into?

Re: hfs4 and megasquirt
 

Yes low z inj. Rc1000

I'm getting power from the same circuit the inj get power


Miss read. Power red is coming from the same circuit all my interior gauges are run off of.
