Looks pretty good Mike. What IAC did you end up using?

If you start getting bored, there are MSIIe variants that people have made which give you great closed loop idle control, TPS noise reduction (great for acceleration enhancement) and load catching (VE and idle based) for things like A/C kicking on. I've been pretty happy with my tune and had plenty of other things to do so I haven't experimented at all lately.

I used the Jeep IAC valve that diyautotune recommended for the expensive but very nice IAC valve housing unit they sell. I may experiment a bit further with other versions of code in the future, but A.) The car is running really well, and B.) Both the EFI and factory engine wiring harnesses are completely out of the car right now.

I do like the sound of closed loop idle control, and the TPS noise reduction; especially the TPS part. My TPS signal is really noisy. If it were a stock engine, I would go to MAP based AE, but these 230 degree cams are a wee bit lumpy, to say the least.

No way you could go MAP based acceleration with that cam I don't think. The code variant is by gslender and can be found here: http://www.msextra.com/forums/download/file.php?id=25407 the documentation, here:https://dl.dropbox.com/u/12773711/v2.8_gslender_modguide.pdf

My TPS signal is now so quiet that I have my acceleration based 100% on it and never get any hiccups. I've toyed around with other features but have been distracted from really spending a lot of time on them. This one feature however makes the switch worthwhile.

The IAC/housing setup sounds similar to what I did for Shannon and Ian's conversions (pics). My throttle body came with an integrated IAC housing and I popped in an identical IAC valve.
