What to use for DataLogging

The raw data can be viewed if exported to an XML or spreadsheet. I can't find the info right now, but I believe Zeitronix may be collected at the same rate but is displayed at the much higher 74 s/sec.

LM1 + Aux box cost is $589 and out of the box you get the following items logged:
RPM, Duty Cycle, Speed, TPS, AFR, Timing, Boost, and Knock (via 5v input)
Along with this you also have the added benefit of a built in accelerometer, which is a great tool that can be used to find weak spots in your tune. It is also portable, so you can use it on your buddies car, doesnt require any splicing, and cheaper then any of the other solutions. Not to mention that it will be nativley supported in EcuFlash in the future.
I really believe this is by far the best solution. Thanks to all for the great feedback on this thread!

I have the LM-1 with the RPM convertor. I might just get the Aux box in the future.

But if what you are saying is correct, then it is the display rater and not the sampling rate that is different. Both ZT and innovate have the same sampling rate but the display of the ZT is faster. Good to know
Part of the issue with wideband datalogging display rates is the response time of the sensors. I've been doing some research on that and it may explain why most of the Bosch-based systems have (what seem to be) very slow output rates. From what I've been able to gather, the Bosch sensor has a response time of 10 Hz.
Personally, I would much rather use the "all in one" datalogger from Evo4Mad that can incorporate all of the on-board factory ECU functions (combined with wideband AFR support). For guys using ECU Flash, I think it will be the way to go. You can then focus on getting the wideband whose hardware best suits your needs (with or without gauge-type display, with or without EGT, with or without optional MAP sensor, with or without NTK sensor support, etc).

I am not really good with programming, but have a question.
Using the EvoScan program, could one install a map sensor and incorporate it into the EvoScan similar to a wideband? I was under the impression the ECU has several un-used inputs that could be very handy for things like EGT and such.
I am assuming that the Evo calculates boost based off the maf reading and not the factory map sensor.

the OE Mitsubishi MAP sensor is a 1 bar sensor.. basically it is just used to calculate the base air density when you start the car, all other calculations are based on this floor value.. The Map sensor itself only reads engine vacuum to sea level for the most part.. Its really only used to compensate for altitude/air density differences..
how is the LC-1 going to interface with EVOScan........ is there going to be another cable to buy what we will have to splice into? or is it going to be a software interface with Logworks and ECUscan??

i would think its going to be a input for the scan software. so then it will just input that way you knew what i mean.

i would think so but im no pro thats a good question for the maker and or jack who knews a lot about this tech programming stuff

As for the accuracy, If it is good enough for MalibuJack, then it is good enough for me.
"Yeah, GM Sensor here.. Its actually pretty accurate if the calibration is right.. If I had the AEM sensor I would have posted a calibration for it. The big problem with accuracy seems to be the scaling, its only as accurate as the scale reference, so if your boosting to 30psi and had to calibrate it based on 0psi-15psi it seems to get thrown off a little.. if you calibrate it from engine vacuum -7 to -14psi through 20-25psi you should get it much closer to being accurate.
Basically all the calibration does is relate a digital value to a gauge value, so its only as accurate as your measurements."

The accuracy is in the calibration of the MAP. I have followed the Calibration proceedure that the dynojet WBC recomends and I have cross refrenced the numbers with information from PLX and GM 3 bar users. The number are very similar to each other.
