The R-500 will log with out a computer. The display if the r-500 is hard to see in the sun and it is not plug and play. You have to program the formulas to get the correct values your looking for . What i mean is the is no R-500 for the EVO it is a generic unit that u have to make work with ur car. i have used the R-500 but never the Zeitronix.

here is some info on the r-500 https://www.evolutionm.net/forums/sh...d.php?t=138570

 

Hmmm maybe I could pick something cheap just to get timing. Either way I'm going to ditch my PLX and get one of these

 

For those looking for a wideband, get something that logs w/o a computer, especially if you do frequent logging under different conditions. Having to have a lap top in your car if you log frequently is a PITA.

Also most widebands come only with the ability to log AFR. You will have to add other parts that the wideband manufacturer sells to log other inputs. For example, if you want to log boost you might need to add a MAP sensor at an additional cost. If you want to log rpm, you might have to tap into the ECU wiring harness or get an inductive pick up clamp and clamp it on the spark plug wire.

 

Zeitronix ZT-2 plus ECU+ for the data logging is an excellent combo. ECU+ logs practically everything you want at 25x per sec on a laptop. You can also hook up your Palm handheld and log via it as well if the laptop is too big. You can display o2, egt, boost, lambda on the ZT-2 LCD, and feed the data to ECU+ to log. www.ecuplus.com

 

the zeitronix has an display that you can get to show you what the logs are i believe. I dont log all the time, just when racing to tune for race fuel so i just use a laptop.

edit :^^ got it first

 

Does the Zeitronix have its own thermocouple unit for the EGT probe? AFAIK, you need a thermocouple to log EGT, the EGT probe is not enough.

 

Nice! Ecu+ is a overkill for what I'm needing. I plan on using the new EcuFlash software to make changes to my custom tune (stock ecu).

I really like that window mount + display... I always have a laptop with me anyways for work so that's no problem. I like to study my logs at work in my spare time

 

If you want to log EGTs with the ZT2 you need to purchase the EGT probe. Zeitronix sells it as an option. The probe comes with a k-grade thermocouple wire. I run ecuFlash on my Evo as well.. and the ECU+ provides the most absolute picture of what's going on when I make changes to my tune. The ECU+ can datalog like there's no tomorrow... and it's very easy to use.

 

can you use any kind of k-probe, or does it have to be zeitronix?
what about for the boost reading, can you tap into the ecu with that?

 

I think all k-type thermocouple are the same. To log EGT you will need a k-type thermocouple and the EGT probe along with whatever logging unit your are using, innovate, PLX, Zeitronix.

To log boost, you will need a 3 bar Map sensor along with whatever logging unit you want to use. You will also need to calibrate the Map sensor to the atmospheric pressure that you are at.

The easiest way to calibrate your MAP sensor is to read the voltage coming out of the sensor after you instal it. Turn your ignition on (engine off) and with a voltmeter read the voltage. That voltage corresponds to 0 psi. Then you will need to get the max and min readings for your MAP sensor. I have a GM and at 0volts=-14.67psi and 5v=31.18 psi. I entered that data in the software of my logging unit and It read my boost perfectly.

 

so you can practically use any kind of map sensor, as long as you configure it right?
where do you tap the map sensor?

and for the wideband O2 sensor, a bung must be welded about 6-10 inches down the downpipe? can you put it down the exhaust, like the O2 sensor bung thats on a test pipe?

 

You need to use a 3 bar or higher MAP sensor. Anything below 3 bar will not work since the EVO boosts 20.5 psi stock. Install the bung at the end of your downpipe, right before your cat. If you have a test pipe that has a bung in it, then go ahead and use it. I would not put a bung after the cat, since a cat will mess up the reading of a wideband O2 sensor.

 

ZEITRONIX has its EGT input built into the ZT2 no matter what options you choose. The base model options have EGT built into the box.

 

When you figure out what you are talking about please come back and share your expert opinion.

As one of 3 Authorized Zeitronix Dealers in the USA, I can tell you for sound advice about Zeitronix products, do not listen to nj266.

You can only use a kavlico 3.5bar map sensor for precision medical grade measurements. If using an AEM wired for speed density, this is the same sensor as the one they sell for $155. Zeitronix sensors are much less.

YOU DO NOT NEED TO MEASURE VOLTAGE OR CALIBRATE THE MAP SENSOR WITH ZEITRONIX.

The software does it for you and "zero's" out the psi reading.

Furthermore, 1 bar = 14.5037738 pounds per square inch

 

Faisal, this guy has no idea, what he is talking about. You can PM me if you want the low down.

You cannot use any kind of MAP sensor if you want an accurate reading. Zeitronix tested the GM 3bar and it was inconsistant and not reasonably accurate. They would not use the same precision sensor as AEM if it was not the best available and most accurate on the market.

The map sensor can be tapped at the FPR line off the intake manifold. The same line they tap the factory gauges into.

If you already have the gauge package, the vacuum line runs behind the glove box and you can "T" into this line and keep your MAP sensor protected from the elements.
