Go into your Zeitronix software and see how flexible it is. It's configurable for altitude, but I'm not sure how far the adjustment can go. Since you are a Zeitronix customer, you should email them and ask. They are super responsive to email tech questions.

Like J_o_T said, the voltages are way different.

 

The things that need to be edited are in the ROM. I had recorded the lowest bit value the sensor could read at 0 PSIa and at its maximum PSIa reading once before using a vacuum pump and a portable compressor tank to slowly increase the pressure until the sensor maxed out. It may be in a thread somewhere but it was over a year ago I think so I can't recall where I had the conversation with MrFred. He is the man to talk to about it though.

 

I don't think the ROM is relevant if he's tapping the sensor output directly for the ZT-2. He's getting the actual voltage from the sensor rather than something processed through the ROM. Maybe I'm misunderstanding...

 

Let me just clarify real quick since I think EVO8LTW is the only one following me here. I want to know if its possible to connect the JDM MAP sensor signal (ECU and JDM sensor set-up in the direct boost control config.) to the ZT-2 datalogger in order to see boost on the Z(R)-2 gauge?

If its possible to do this, I'm not sure where I should get the signal from? Either from the JDM map sensor itself or from the ECU? I don't know which one would be better/more feasible.

 

you can't for the zr-2, you need the zeitronix boost sensor for the guage.

you can for the zt-2 if you have the jdm map scaling but can only view it on the laptop.

 

If you can read boost from the JDM MAP sensor on the laptop through the zt-2 datalogger, then why wouldn't you be able to read it on the zr-2 gauge? If I'm correct the zr-2 just connects directly to the zt-2 datalogger through a serial cable and displays readings just as if you were using a laptop. Am I way off base on this?

 

Oh, didn't realize you were trying to read boost off of the JDM map sensor via the Zeitronix gauge. That cannot be done unless Zeitronix wanted to lose money by modding their module to read the voltage range of the JDM map...that's not happening for the obvious reason that people wouldn't buy their sensor.

You can hook it up via the USER input and create an Evoscan formula to read boost that way but why would anyone do that when the ROM can be configured to work perfectly with the JDM map sesnor so its directly wired tot he ECU for datalogging?

 

I have the JDM map configured to log from the ecu, I just wanted to to see if I could "tap" the signal for the zt-2 datalogger in order to see boost via the zR-2 gauge. I like the zR-2 gauge and would rather not have two map sensors for reading boost. Its all good though, I figured it wasn't likely but I just wanted to confirm. Guess I shouldn't be greedy! Thanks for the help.

 

You could get a Zeitronix and sell the JDM sensor and have one sensor that does both.

 

Yeah but as I stated earlier, I don't think MrFred ever figured out the best way to reconfigure the rom's map sensor settings to with with the zt2 map sensor.

 

Oh...I didn't think of that because I'm running the 96530006 ROM, where you don't need that patch. I also am not using ECU-controlled boost.

 

Hey guys, I'm new and just catching up here so please excuse me if I've not found the answer to the above question elsewhere...

I'm trying to figure out if I can use the RoadRace MDP sensor adapter to use my ZT-2 MAP sensor instead of an OMNI/JDM 3-bar. It sounds like there might have been some range and scaling issues?

Thanks!

 

Someone who I tuned also wanted to use the ZTX MAP sensor in place of the stock MAP sensor. I don't recall if he had the 3-bar or 5-bar version, but whichever it was, we were able to get it scaled reading correctly. He splits the sensors signal into 2; one to the ZTX box, and one to where the stock sensor connects.

 

Perfect. Thanks Raptord.

I figured this wouldn't be a show stopper with all the other OpenECU work going on. I'm coming from the Nissan world using NisTune and it's amazing how good the Mitsu ECU platform is...
