HFS-3 not spraying ::mystery solved::

[Richard L]

You cannot change the fuel injector size without affecting the aquamist's setting

Yes. x1.5 and reset the failsafe window.

What about my question of switching to MPS from IDC? Can you see the picture I linked?

[Richard L]

Change the IDC to MPS will only change the trigger point, the system, still follow iDC. Select x1.5 on power fuel and x1 on E85.

[Arthurwiljami]

So there really isn't a way to run WI with both fuels unless I'll do something like sniper did above? And I'd still need to find correct threshold point for each fuel which means opening/adjusting thres point every time fuel changes.

[Richard L]

You need to change the iDC gain not threshold. The system prefers to work with full idc swing rather just 60% max.

My HFS-3 is v2 SN:10460 does this have the pre:amp option because it is not in the manual until v3.0?

And just to confirm there is no option for MAP control only?

[Richard L]

Your controller is the first generation and does not have this option, it is approx. 5 years old. Time to get a newer controller?

[Arthurwiljami]

I did spray test using "INJ" and "SYS" on the controller. Both nozzles sprayed fine but none of the leds didn't lit up in the bargraph? Shouldn't it lit all 8? Adjusting "FC" to max didn't make any difference.

Edit:
Disabled the failsafe with "DFS" and went to test drive. Didn't see any flow and the "w.injection" indicator led did not lit up looks like the system does not activate at any point.

Is this all because of too big injectors or is there some other issues going on with the system?
Gain turned to almost full clockwise.

[Richard L]

Unfortunate this is the case. running over large injectors will have this effect. The duty cycle is too low for the first generation of H3 system.

You should consider getting a newer HFS3 controller. The latest (V3.1) allows you to scale up the incoming IDC signal in six steps.

Post a picture of the under side of the circuit board you might be lucky and have a idc re-scaler within.

[Arthurwiljami]

OK, I'll need to consider the newest version. Assume the wiring harness is the same.

Looked from the manual about the SSG option. If I understand correctly it works on/off principle and ignores IDC. Threshold only sets the trigger point and then its full flow?
