As most of you know the 0-5 volt linear output from your wideband could be logged via the greddy pressure port (if you weren't using a pressure sensor) or via the TPS (if you weren't using the TPS map - or all the values were the same)

Now we can finally use the 2nd maf wire to datalog. From the yahoo e-manage groups:

Scroll down about halfway and save the link that Hau has posted. You will have to remove the comma. Or just click from here:

once you save the file you will also need .NET framework 1.1 - you can download this from microsoft. I just typed ".net framework 1.1" into a yahoo search and it worked just fine for me.

That is all you will need to do in order to run the program. With this you can datalog a/f, rpm, and boost pressure all on one graph.

In addition there is an autotune feature that a single turbo supra owner has said worked great. In put the desired a/f ratio and it should adjust your air flow map. I'm going to try this out first under vacuum and see how well it works. This is just a bonus though, the e-manage has always been a great deal but lacked an input for widebands to be datalogged. Now it has that ability.

I asked Hau for his paypal info and will gladly send a few dollars his way if he posts it, I realize that many (especially fellow fc owners) are cheap but I think he's definitely earned it.
