Browningderek, I want to say thanks for your thread, I also have a HTA86 with e85 and 1600 cc bosch injectors in an EVO9. My idle was not good and following your suggestions I was able to fix it. AEM instructions suck.
I had a rough time trying not to leave the tps % in 0, finally I got .8%,
also I left the Idle feedback minimum= -10% and Idle feedback maximum= 15%, still trying to understand everything you wrote , Im not a tuner , thanks again for your thread.

Check your fuel decel settings. after you got the tps corrected it might have to been changed.
I always try to find the lowest "fuel decel tps %" i can and the decel still work. Around 2% should be close.

also wanted to add regarding the decel issues for some... on the AEM series2 boxes / aemtuner, you MAY run into the same problems i did. All of the idle help on this page works... but when i switched over to the series2 box i had an awful idle hunt and stalling issues. Spent a week or two working it over w/ all these tips like i did w/ the older series1 box to no avail. Turns out the FUEL OFF RPM was set too low from AEM. It was set at 1500rpm. I raised it to 1900rpm and the stalling/hunting went away. The IAC duty% started to finally work as well. I suspect it was fighting the FUEL OFF situation due to the rpm range too low? Btw you can also set the vacuum range when fuel goes off on decel(FUEL OFF LOAD) as well. I have mine set at -8psi vac. Its 2psi lower than the lowest idle vac, so should only kick on when the vacuum is really low on decel. This feature shuts off the injectors during decel, i think when its set too low the idle functions have no fuel and therefore either stall out or hunt because its trying its best to keep it alive w/ no fuel. I believe when i raised it, it allowed the idle rpm range to revert back to the fuel map and allow the idle functions to work properly. Anyways... in case any of you had similar issues.

Hello there, this is an awesome thread!!
What about people that are running without an ISC motor?
Would there best friends would be BISS, Ign Vs. Idle Rpm, and Base Map??
Also do i have to worry about the Idle Learned Value when running without the ISC? Thank you
