First you have to find out whether your hall sender shorts the signal terminal to the negative (ground) or to the positive terminal. You can test this easily with a multitester. If it shorts to ground, install a pullup resistor (1k ohm is ok) from the signal terminal to the positive terminal. If it ...

Ok I reconnected by bech testing setup so that MS2 was grounded directly to the power source (instead of through the stim). The same was done with the 12 V power lead to MS2. Now it works perfectly!!!!
Look at the attached "perfect.jpg" log (I have both a real high-impedance injector and the Bosch ...

Thanks for the response davezed!

I forgot to say I'm low side switching (i.e. one terminal of the IAC valve goes directly to 12 V (at the pwer source) and the other terminal is connected to the FIdle lead from the MS2).

I use a 12 V 2 A power source directly off the wall. The MS2 is grounded to ...

First, I'm using MS2 in a PCB v3.0 with the v2.686t6 code with a Bosch 2 wire PWM Idle Valve. I've assembled the PCB according to the instructions for the PWM Idle control and I'm also using a 1N4001 diode across the valve itself. I'm using 240 Hz PWM frequency and it's very smooth (80 Hz was very ...

Has anyone tried to use Dual Table mode and set VE Table 2 and the INJ-2 output to control a water pump for water injection? It would be kinda PWM for the pump.
That way you could have gradual injection, proportional to MAP and RPM instead of the typical on/off water injection.
