Anyone logging these two from existing/stock sensors? If so, do you have wiring diagram details?
Trying to see if avoiding adding more sensors is practical.
Thx

 

I don't pull directly from those 2 sensors personally as I've added a Zeitronix MAP sensor, its pretty easy to do. I pull IAT's from the OBD2 port through the Dashdaq that ties in with the Zietronix unit.

The fewer PIDs you log from OBD2 the better. I believe I pull TPS and RPM directly from the ECU, if you need I should be able to locate the pinouts diagram I have for those, others may be able to chime in with that data as well.

 

Yeah, I pull RPM and TPS from ECU harness, and was just thinking that picking up AIT and MAP should be very doable there also. (thus, saving some hassle, expense, and time).
Thanks for tips and offer to help though.

 

Yes both can pulled, but with the iat sensor since there's no calculation from dashdaq yet(waiting on it) not worth because all it will show is voltage. The map can be used as one of your user inputs, C3 10 Red/Gray , from my notes if I remember correctly and there's a calculation you will have to add into the dashdaq that's posted on the forum somewhere, but like jmb said much easier buying the boost sensor from zeitronix and tapping the surge tank.

 

Wow! You guys are FAST--thx for lighting responses.

Since DashDaq's are apparently out of production (and impossible to find) I am trying to do it all with ZT2. Plus the OBDII stuff is sooooo slow, it's near worthless for logging if you ask it for more then 2 data-streams.

I'd assume the Zeitronix software will read it, but can't recall if you can make any scaling calcs with it since it's just looking for 1-5V, I think.

Since stock MAP and AIT are already there, and the tune is based upon what they are actually reading, seems like a good plan unless the Z software won't report it correctly.

Is there more to consider?

 

I don't think the z SW will make the calculations like the dashdaq, so get the boost sensor , not that expensive if you shop around. I don't know if the dashdaq is not manufactured anymore but I just sent mine in to get repaired so at least they still support it lol

 

Apparently, they are coming out with some "N-Dash" thing that is supposed to be new and improved.
The cost of the sensor isn't the issue as much as just trying not cut/hack much. May have to anyway.
Is there enough material in those surge tanks to tap it, or does a bung need to be welded in?
Thx

 

I bought the bung off of Z's website and welded it on.

Did Drew technologies get bought out? I'm curious to see if that new gadget will show up on Zeitrnoix's website soon.

 

Ya not a problem in the surge tank bro

 

I didn't use a bung, had actually tapped into it for my first boist sensor(aem) and used that tap again, no issues

 

I was looking at Zeitronix website last week, because in the past they offered a package deal with the Dashdaq. I have to wait to see what they come out with now?

And I'm all set with another bung on my headers which I hope to use soon?

 

come out my way you can use my dashdaq or maybe I take a ride to you

 

yea im looking to start monitoring as well
I just need to pick a good setup

 

IMO , the AEM that logs boost and afr with failsafe (30-4900) is a good one for 300$ , uses no obd or the dashdaq with zt2 but costs more

The reason for the zt2 is because you can log real time on rpm,tps,boost and not have to go through the obd , the difference between the obd and zt2 is easily seen on logs.

 

Zeitronix logging is very good and fast. Software is not convoluted like many,and the stuff just works!

 

If this is meant for me, I appreciate the offer, but I would rather own one and keep it in the car
Thanks -

 

no for mindbend.

 

The scaling is different on the IAT, I advise adding the aftermarket sensor. The scaling is different because the resolution on the aftermarket sensor is so much greater

I have a GM sensor and it reading is 10F higher than the reading from the OBD2 port

 

I handed dashdaq the info greaser gave there, I think they will have something soon to put into the dashdaq calculator

 

Two additional important parameters that can be logged is Fuel Pressure and injector Duty Cycle. For Duty Cycle I had to add Innovate SSI-4 to DashDaq.

BTW, I have a DashDaq for sale, if anyone is interested. $300 including shipping to CONUS. 9 out of 10 condition. Includes OBD2 cable. Does not include Zeitronix cable and Zeitronix license.

 

That's a good price even without the license! Btw guys it's only 50$ for the license

 

Anyone ever figure out how to get MAP/Boost from the ECUbwith the Ndash?

 

I posted above...

Map is socket 3- pin 10 - red/grey wire

 

I am thinking of adding a second ZT map sensor to the other surge tank, a second EGT, as well as a fuel pressure sensor and second AFR off of another ZT2. Would be helpful to monitor both banks.
