Default HFS-5 DDS3 V8 install ?- Turbo Suzuki samurai/tracker TBI

Hey guys. Just finished turbo setup in my samurai and have a question.

Looking to see if the hfs-5 dds3 v8 aquamist kit can be installed in a TBI vehicle.
If so.....
Where do i get the trigger signal from?



The vehicle is an 87 suzuki samurai w/ 93 geo tracker engine/ecm
Currently running 5psi/boost 93 octane.
Stock geo tracker ecu.



Thanks
Joe

Everything is installed except for the FIA2 and trigger wire.

So far so good. Just not sure where to get this signal from . I dont want to mess anything up.

Just got done wiring the kit.
Everything seems to be working like it should. Just need to adjust gauge and dds3v8.

I installed everything according to the diagram below.
http://www.aquamist.co.uk/forum/gall...S3v8/HFS-5.gif


Engine running at idle = Fuel Injection green LED on. Red LED off
Engine running rev. engine = Water injection Red LED blinks rapidly but no flow or pump activating.

Im thinking it has to do with adj to both controller and gauge?


Thanks

I have been away for the last two weeks. just catching up. Sorry.

I had a look on the diagram, very nice and clear. I think the injector is driven by a "peak and hold" driver so the signal is extremely wak during the "hold" period. The "peak" period is good but only around 1mS of so. The DDS3v8 will not be able to detect those signals.

The green wire of the FIA2 should be connected to pin A17.

The HFS-5 consists of a FIA2 module, can you tell me if you can see a purple wire coming out of the FIA2 harness. This wire has an output of 0-5V, representing the 0-100% DC of the fuel injector.

Bofore we go any further, I like ot know if the FIA2 is reading the fuel injector correctly first.

I have another question, is side kick a addon unit to the original ECU. What is its function since the ECU can drive the stock injector anyway.

Richard
The sidekick/tracker ecu is whats running the tbi engine. The engine was swapped from a geo tracker.


Thanks again for all your help. I will check everything tomorrow and post the results.



Cheers,
Joe
