Zeitronix/Trinity, Making it Work (PIC HEAVY)

[Cruisin1966]

In my case I don't have a Zeitronix. I'm using a DynoJet. Any ideas on the color wise to use from the DynoJet to Trinity.
BTW, I'm a little color blind...or so I'm told. LOL

Looks like you need a Data Acquisition cable (76950114), if it didn't come in the kit you have.

Thanks TJ for pointing me to this thread; to the OP; great How-To article btw; you might consider changing the wording when referring to the white lead (pin2) exiting the ZT-2 controller from "Analog input" to "Analog Out". Might be confusing for folks.

The other thing that is a concern; although the upper and lower wideband limits can be set within the Trinity, there might be problems because the Trinity is assuming a linear-relationship device is being connected to the analog I/P (3-pos 2.5mm plug).

The model year/iteration of various ZT-2 units is very important to know to ensure that the 0-5V reference being sent to the Trinity is indeed a linear relationship.

That white lead (FYI it's not a wire; a wire is a single strand, multiple strands make up a lead, a cable is 2 or more leads) can be either linear OR non-linear depending which iteration of ZT-2 controller you have; Zeitronix Zt-2 Wideband Analog Output

Failure to select the correct lead (white or purple) could cause erroneous readings right in the area we need the most accuracy from the Bosch LSU (PN 17014) O2 sensor (most of the aftermarket wideband systems are suppying this PN with their systems).

As far as adding the 0-5V reference signal from the Dynojet controller to the Trinity; Cruisin1966 has pointed to the correct PN (sect. 6), however it might be prudent to get the 3-wire version that has an external system GND (sect. 10, PN: 76950118). Again, because the Trinity only accepts min/max, those values might need to come from Dynojet (it's possible they are the same as for the Zeitronix/Bosch system - but need to ask).

Note; it is very important to ensure the grounding (either reference or system) on wideband systems is done not only correctly, but securely. This is one the biggest problems casuing inaccurate/fluctuating readouts.

TJ; if you don't have that 2 or 3-wire comm cable I can make one (I manufacturer wiring harnesses for R/C aircraft/military UAV's). It's likely male/female pin systems on 0.100" spacing...

There you go talking Asian to me again. Remember Simon, I'm just a redneck heavy tow operator!

Sorry TJ; in simple terms the 2006 to 2009 Zeitronix ZT-2's pin2 (white lead) is non-linear (purple lead is actually linear O/P)...unless you go into the software and set it (pin2) to output a linear function. In 2010 versions of the ZT-2, pin2 automatically defaults to linear O/P.

Regarding your Dynojet; talk to the manufacturer to confirm the upper/lower range is indeed similar to Zeitronix/Bosch O2 sensor (9.6 lower limit/19.6 upper limit). If you do require a cable and you think the cost is prohibitive, I'll fabricate one for you at double that...just kidding :^)

[HeavyHook]

You know buddy....it's not always about cost. Most times, it is what it is. No getting around it. Sometimes I don't wanna wait 10 days to 3 weeks to get something from the US.

[Hemissary]

Not my intent to imply; however as you know there is sh!t that should cost close to sh!t...but it does not.

It's somewhat(!) higher in price...for no good reason.

So I can find this again...

mines not working i got the second plug that you suggested and it has a red a black and a second black thicker what do i do with that wire also i have the ZT-3 only has red, white black and purple wire

but when i do as said it just sits on 9.5 and the gauge reads 9.5/9.5 the whole time

x2. Same question here with ZT-3
