    Well my progress was delayed by an wrist injury and holidays, but hopefully this weekend the subframe will be pulled to install the engine. I did do a little tuning on my buddies lt1 camaro. Amazed at how easy it was, of course all I did was tune out the emissions crap

    it was a long time ago and a borrowed unit? it had a serial cable for configuration. you could set the 0v=AFR and 5v=AFR, so you could use 9:1-16:1 or something and it would be very accurate. i think there are other widebands with this level of configuration. just don't buy an unconfigurable one...

    Hope things go better for you than mine did. I did manage to get the engine stuffed back in last saturday, but not before I got a bad cramp tightening the last motor mount bolt and dropped the ratchet on my head. Thankfully it didn't need stitches.

    I'll have to read the manuals, but it looks like all of AEM's have adjustable analog outputs. This one looks like what I was wanting, but it seems like the integrated gauge models are a lot cheaper. I have to wonder why.

    While this one is ~$70 cheaper on that one website that starts with an a.

    After quite a bit of searching I've been unable to locate anything they're currently selling that is configurable over serial. They do make a 4 channel controller that can be configured over CAN but it's awfully pricey.

    Thinking I'm going to buy one of these gauge setups - they appear to be quite a bit cheaper for the same functionality as the "inline" setups. I would assume this is because the electronics for the gauges don't need to be weather resistant.

    I got an Innovate mtx-l unit. It does have logging capabilities through serial and can be configured. I don`t recommend it since after not much use it produce some electrical noise on the radio.
    The best way to log will be through serial integration over com port. Not sure how hard it will be to add that in eehack.

    Look at the wideband controllers sold by Ecotrons. May be what you are looking for.

    it wasn't an AEM i used before, it was an innovate LC series gauge

    this is the key to getting decent output from that gauge, just set a narrow AFR range from 0-5

    Soo, last night i finally got some time to do some WOT tuning, but, I wasnīt able to make any changes in TunerPro.

    This morning i tried to change the .XDF file for an otherone (after i reinstalled TunerPro), and then it was possible...

    I forgot to mention itīs the same bin, different values depending of which XDF Iīm using.
    The EE XDF is from TunerPro homepage.

    Now I donīt know which to use, but the EEX doesnīt allow me to change the table, and as far as I have seen itīs the only table that doesnīt work correctly for me.

    I attatched the .BIN, if anyone have the time to take a look of it...
