I'm looking at hondata and the aem ems ecu systems and want to get opinions pro and con on both. I have an 88 crx si with b16 swap a t3 turbo .63a/r on the turbine and .43a/r on the compressor, it will be a daily driver on 9-10 lbs of boost. It will only see the track after Each upgrade just to see what it can do so things like launch control aren't neccessarily needed. I have heard the aem won't fit in the same area as the stock ecu, true or false? I plan on being able to run 22psi and daily drive 15psi, but thats down the road.

If I go hondata which stage would be best. I know for hondata to go see vapor, ( vapor if you read this please put in your 2cents, also do you guys tune the aem).

If I go aem who in the bay area tunes it.

I have found out that the hondata once originally tuned for a few boost levels it can then extrapolate any other boost levels you throw at it.
