ok, its not- but

What is a good data logger to see IAT and other data for a given period of time. Any suggestions?

What data can be captured. i want to use for track runs and post tuning to see how things look given different temps, alt, DA ect

Good thread, I'd like to know what people are using too.

I've heard lots of good things about Racelogic's products but never used them myself: http://www.racelogic.co.uk/

I love my Dashdaq/Zeitronix combo. http://dashdaq.com/ or http://www.zeitronix.com/Products/dashdaq/dashdaq.htm. I ordered mine from Dave at HorsepowerFreaks and couldn't be happier.

Im not sure what the OBD connector can provide. Can you see AFR and boost? (I know you can see AFR).. what else is benificial? Looks like the kit is around $699, with some things I don't need like GPS.. however it looks great

Edit.. I guess you need GPS if you are getting GPS data into logger (Speed ect via actuals)

Id like to see:

Speed
RPM's
Boost
AFR
Timing
Speed


What else??

You need the Zeitronix to monitor your afrs. I believe either obd or Zeitronix can read boost. Also, there are 2 Dashdaqs, one with GPS, one without. I have the one without. You can monitor IATs, timing, Fuel trims, ECT, EGT, etc. It really is amazing what it can do. Of course the more functions you run off the OBD the slower it will read, so it is nice to run features off the Zeitronix.

What is the zt-2 connector? Do you use that or native OBDII?

Just a quick 2 cents to make sure all know how horrific our obd2 transfer rate is on data. I think the e55 is one of the slowest. Bout the best sample rate I have got on my 03 is bout a sample every .75 secs. In a 9 sec throttle burst or 11sec quarter run, that is not a whole bunch of samples. I use auto enginuity software and like it but ugh....those samples. Not sure why so darn slow, maybe all those sensors or somethin.

Ditto on what 930Chas (Charlie) is recommending. I use the same setup and I'm very happy with my results. Most people won't go as extreme as myself but if I could spend thousands on my motor a measly 1200-1300 isn't much to monitor my car under WOT. Is it overkill, maybe, has it saved me before...yes. That one time paid for itself over and over again.

Running as little parameters as through the OBD will give you the best possible speed. IMO, at a minimum you should log timing and IAT's through the OBD like myself and use a wideband to check on your afr's. Just my $.02.

930chas

Haha...I wouldn't be running this setup if it weren't for you brotha!!

on my dashdaq/zt-2 setup my boost, fuel pressure and afr's are monitered by separate and independent sensors. timing, ect, iat, max boost and a host of other readings are captured by the obdII. you can add as many sensors as you have parameters to moniter if you choose

the obdII can not read wideband afr which is the reason for the zeitronix zt-2 addon.

The obd port is slow but with a scan tool you can see your iats just fine,I use it for that and a wide band for a/f.

Monitoring iat's through the OBD works out fine since loggin speed isn't important, it's more of a gradual rise in temps. What I wish we could do is monitor the knock counts like other cars. This to me would help tremendously in fine tuning our beast.

Bramage

How are multiple units connected? Specificly, where does the wideband connect?

skratch77

you have to install an 02 sensor in your exh pipe and wire it up in the car.You technically need 2 for both banks but I just installed a bung on both sides and switch the 02 back and forth to see how its doing.

Guys- This is great information, and a must for anyone who is tinkering, and wants to make sure they are safe. I am going to get the Zeitronix / Dasdaq kit. This looks very comrehensive, and will allow a slightly more aggressive tune in the future, and still allow me to monitor crital functions. In terms of other sensors, are you guys running any secondary sendors (IAT, Boost), or just the wideband O2 connection(s)? I assume the rest is coming from OBD (very slowly)

Ill probably order the kit next week, and have my exhaust guy get busy. Just want to make sure I don't need to tap any other sensors when I am in there.

Do you / tuner ever use this in addition to what the Dyno is showing to help fine tune? Seems like a lot on information here would be benificial during a tune.

you only need a single bung just before the oem O2 sensor for the widenband. for the boost sensor you need to drill intoi the y pipe below the t/b . fuel pressure sensor is installed inthe the end of the fuel rail. the obd II readings arent really slow unless you have a ton coming in at once. i have 12 readings and they function very quickly
you will be very happy with the dashdaq and you will be able to datalog with either a sim card or you can cable directly to a laptop and store the info there

if you contact rob at needswings.com he can assist you in determining exactly how many sensors and cables you will need and set you up with a complete pkg

I have a phormula KS4, and its one of the best pieces of equipment I have had on my cars for monitoring knock.

I use Zeitronix and DashDaq and am very happy with it. Here are pics of my setup:

My KS-4 is waiting to be installed. It goes in the V under the supercharger. Not ready to mess with it yet.
Now... This setup looks $$$, but if you think about it as if it was a mobile Dyno, then you will see how it is not that bad ($$$ wise).

Im lining up the parts now... Just trying to figure out what other wideband sensors I will need

320 dreamer

you only need 1 wideband sensor to moniter afr's. all the others are simply sensore that convert fluid or pressure to electrical impulse
