95 Integra LS Auto ECU?

I have a 1995 Automatic Integra LS. So far I have done intake, header, and exhaust; I want to know if there will be significant benefit noticed from slapping on a Hondata ECU on my car. Also, if I put in new Crane cams will I have to get the ECU redone? Will there be a lot more stress on my transmission? And last question, how much will it all cost? And what exactly is it?

Thanks for your time.

All of your Hondata questions can be answered by simply taking the time to read Hondata's web site.

Regarding your non-Hondata questions:

Higher lift cams will allow more air to enter the cylinder per stroke, so yes, you'll probably want to remap the fuel tables in the ECU at that point for maximum benefit.

Transmission stress is caused primarily by excessive peak torque output from the engine. With typical NA mods (I/H/E, cams, porting, ECU) you're probably going to see a maximum gain of 10-20% over the stock peak torque. For forced induction, this really only becomes a concern if you're going the turbo route; supercharged engines typically have a much flatter torque curve with lower peak torque. If you're going NA with an automatic tranny, it's not even an issue, so don't worry about it.
