I'm looking at a PS1000 for my S5 TII and have a few questions:

According to the Haltech website (http://www.haltech.com/index.php/pro...num-sport-1000) the PS1000 has "Up to 9 additional user-definable auxillary outputs (Depending on configuration)". When used in a 13B configuration how many outputs are still available?

I'm assuming that the "plug and play" harnesses connect the Haltech to the necessary stock sensors, ignition, and fuel injectors, but that the emissions solenoids are neither connected nor controlled? I'm in California and would need to keep my emissions; so I'd probably have to manually configure some of the auxiliary outputs to control my emissions solenoids?

The PS1000 summary also says that an output could be used for "Extra injector control". I think it only has 4 injector drivers, so how does this work? Would I need an external injector driver of some sort?

 

When setup for stock FC or FD ignition, you will have seven available outputs. If you use the stock FC ignition, you will be able to use all seven of those outputs for whatever you want. If you swap to another type of ignition, or if you are working with an FD or 1st gen chassis, you will need to dedicate DPO1 as a tach driver.

If you move from the stock wastespark setup on the FC or FD to a direct-fire setup, you will lose one output.

You also have one stepper motor output than can be used to drive the OMP or a stepper motor idle valve.

The S5 patch loom runs the wastegate solenoid, AC, BAC, and VDI on the NA cars. So, as you suspected, the emissions solenoids are not controlled.

DPO17 and 18 can be configured as extra injector outputs. These are the only two channels, other than actual injector channels, that can sink the load of an injector and can be used to drive additional injectors. These outputs are pulsed at the same time as injector 1 with the same pulse width as the secondary injectors. All injector channels are capable of supporting two low impedance injectors. So a 1000 could support up to 12 low impedance injectors.

 

Thanks, that answers a lot.

It sounds like the patch loom is not setup to run the OMP either? I was planning on the stock ignition; so one of the outputs would be used for the OMP, then the wastegate, AC, and BAC; so only 3 outputs left for me? Might have to get the PS2000...

Similar question on the input side; of the 8 "auxiliary" inputs, how many are left after install? Does the patch loom actually use the AFM, or is it bypassed in favor of a MAP sensor?

If I get the patch loom, I would hope that the kit includes connector pins or pigtails for the unused inputs/outputs?

 

Yes, the patch loom is setup to run the OMP. The OMP is run off the stepper motor output, which is a dedicated output that is not otherwise user defined. So it would not be considered as one of the programmable outputs in what I posted earlier.

With the patch loom the inputs are dedicated as such:
OMP Feedback - Analog
AC Input - DSI

That leaves three analog inputs, three digital pulsed inputs, and the dedicated O2 input.

The kit does not include additional pins. We can include them if you're purchasing through us.

You will need to make sure you can program the outputs to do what you're looking to do with the various emissions solenoids. You will be able to set various RPM, MAP, or TPS switches but the ECU doesn't have the ability to do very many if/and type switches.

 

Yeah, I'll have to research the FC wiring a little more. Been playing with the FD lately; haven't looked at the FC stuff in a while.

How feasible is it to wire the Haltech and stock ECU in parallel, and let the Haltech control fuel/ignition/wastegate and have the stock ECU control emissions stuff? Can they both receive a good CAS signal at the same time, or does tee-ing into the wiring degrade the signal too much?

 

I guess when it comes time for smog checks I could always just unplug the Haltech and plug the stock ECU back in (and disconnect the boost control, just run off the wastegate spring)
