I have the EMU and was going to install it this weekend, but got invited to a nice beach party. I spoke with a few people at Greddy about the setup, and yes as someone stated before, he told me to use the 3000GT as a baseline in the setup as they have a similar KV AFM engine size etc...
I also asked him about the conversion to remove the MAF and go pressure sensor. He said it would require a bit of datalogging and tuning, but yes it is doable. The A/F option port allows you to have the computer automatically tune to a preset A/F ratio which it reads from a Wideband sensor. I may be the first one to get it going, but we'll see. I have lots planned otherwise over the next week/weekend.
Also, I'd like to actually speak with some of the guys that got the EMB running on the 7M, so I can get some input, as it seems many of the settings in the support tool are the same. So, if you have it up and running on a 7M, PM me.
