From what I hear the LC-1 from Innovate (~ $200) is fairly easy to incorporate into BE, either via the EGR input (if you have removed your EGR), or via a DATAQ.
For info on DATAQ... Data Acquisition Starter Kits
I *think* you are looking at DI-194RS or DI148U, but verify this with a search on eectuning.org... it's been a long time since I have put any thought into this...
Once you have things sorted out and working properly, I would load the MAF Transfer for the 73mm C&L, Load the Template from Tunexchange for the 24's, and give it some time to settle in. Check the KAMRF's (feedback on the adaptive activity). You may want to tweak the injector values or MAF Transfer a little at that point.
Then you may also see some impressive results to low rpm drivability with some tweaking of the Injector Timing. This is where I relied pretty heavily on EA, but EA will help you with the MAF Transfer and Injector slopes as well.
There's some other stuff to work in there like vBat as well, but just those changes should make a noticable difference in how the car drives...
I noticed in ea under maf it has the exact table I need to get started as some others. can I utilize these?
