Not really. A wideband is not something you can rreally borrow? You need to tap a hole for the wideband sensor

otherwise it looks like you need the lma-3 to log boost.
No one knows for sure if the jdm evo map sensor will work on a usdm. I do not think it has been tested yet.

There are two ways to log boost with Innovate products if you do not want to get an LMA-3

1. LM-1+LMA-2+ 3-3.5 Bar Map Sensor
2. LC-1+SSI-4+3-3.5 Bar Map Sensor

the lma-3 has a built in map sensor and other features, but it adds $250 dollars to the concept. so a LC-1 and the LMA-3 might be more direct.

You are correct. And the LMA-3 allows you more parameters and flexibility.

Zeitronix ZT2 wideband ($274) + Evoscan ($25) + tactrix cable ($96) is the way to go.

Other options are ZT2 $274 + Mitsulogger $0 + tactrix cable ($96)

or

ZT2 $274 + Logworks ($0)+ tactrix cable ($96)

This is incorrect info. It creates the impression that all you have to do is connect ZT2 to Logworks and it will work. It does not work that way. You need the proper plug-ins in logworks for it to accept data from ZT2. To my knowledge, there are no such plug-ins for ZT2 in Logworks.

According to the jfitz, other widebands are compatible.

Lets assume that it is more trouble than its worth to use Logworks with ZEITRONIX.

ZEITRONIX ($274) + MJ Mitsulogger ($0) integration underway
ZEITRONIX ($274) + Evo4mad's Evoscan ($25) integration underway (concurrent logging currently available)

Other loggers can accept data from Innovate products IF those logging devices use the SDK packet that Innovate give away.

Second, You will need PLUG-INs to make Logworks accept data from another source like ZT2, for example.

Before the Tactrix cable plug-ins were added to Logoworks, Logworks would not accept data from the Tactrix cable.

You cannot simple plug ZT2 data output into Logworks and expect it to work.

I use the Zeitronix and Evoscan for now. Ill be switching back to mitsulogger as soon as Jack releases a new update.

As many will follow suit. Big thanks once again to Jack for all he does for the community.

I think that MJ just got an LC-1 from us. I know he is familiar with some other open source loggers that already use our SDK. If he drops it in, great, that is what it is for.

He also expressed some interest in the LogWorks plug-in architecture. So I told him he would be welcome to get early releases of all the LW3 SDK features (many of which are in LW2 but undocumented - which is how the tactrix plug in runs).

I'm a little confused about 'EvoScan being implemented...' comments above. According to the web site, LM-1 and LC-1 support are already in. I know that we answered some questions about LC-1 serial output from Evo4mad on our forum back in September.

One comment I have about the setups being bandied about - you need to be careful about MAP sensors. In the LMA-3 (and our DL-32) we use both a high resolution ADC and a configurable input amp for the sensor. That is how we support all the modes of absolute and relative pressure.

If you are just using most MAP sensors into a standard 0-5 logging input, you need to make sure that the logging system can handle non standard min and max voltages and let you build a non-linear voltage->pressure table. The sensors are virtually never linear, seldom reach rails, and almost always have a slight DC offset from their data sheet.

I know that you can correct for this on all our input sources (LM-1, SSI-4, LMA-3, etc.) and I am sure that some other vendors and loggers allow this as well. But if your system of choice does not, you'll save a lot of grief by spending a little more and getting something that already converts sensor input to a linear, calibrated scale. For example, you could take the analog output from our LMA-3 into a sytem that only offers fixed, linear, 0-5V sampling.
