Hey Grumpy, Is this a good upgrade over the stock 746 ecm? The 746 is to slow to get good real time data from making tuning more difficult than it has to be. The 749 seems to have so much more potential to add options to as well as just tuning a n/a engine. Is this a hard swap or a fairly easy one compared to what I would have to do to get a faster data loging rate?

If anyone has done this swap on a tbi car or has any imput to add, please chime in.

I searched the archives and found most all threads and post geared towards multi port applications. If someone knows of a thread or a link to another site with credible info, that would be nice as well.

Thanks, Steve
