So what's some prices on standalone ECUs and how hard is wiring them up to an 85 13b? i know practically nothing about ECUs so tell a little about them...how hard is it to tune the fuel curves... ect.

Pricing is from $800 to $2,000 for a budget EMS, and can go up to $8,000 or more for a professional EMS. Much like buying a new car, the pricing depends a lot on which options you prefer and what kind of deal you can work out with the seller. If you don't know how to tune or install an EMS, I suggest getting an installation and tuning package deal from your local rotary-smart EMS dealer.

This site covers the basics of wiring up an EMS to a 13B. Most of the EMS products have a similar procedure, although the Electromotive products require extra work to install their timing wheel.

Setting up the values in a modern windows-based EMS is pretty easy for anybody who has enough computer skills to post on this internet forum. Tuning is the difficult part, and should be left to a professional for the initial tuning. Once the engine is tuned, a less-experienced person can make minor tuning adjustments without blowing up the engine, but there isn't much reason to mess with a tuned EMS unless you just want to try and learn the system for yourself. A wideband O2 sensor will help you understand how the engine is performing if you have no clue about tuning by sight, sound, smell, etc. However, contrary to what you may read on the internet, a wideband O2 sensor does not come with an engineering degree, ASE certification, or a brain download of several years of tuning experience, so you will still be just one step above completely lost. Pre-reading the installation manual of different EMS products prior to selecting one will also help you understand their capabilites and differences, as well as EFI in general.

This is the EFI Basics Manual for the AEM EMS. It is very good for nubies even though the AEM EMS only works on the 3Gen RX-7. (Right Click & Save Target As)

You can download the Wolf EMS manual and software so you can play with it on your computer. Some of the other EMS web sites also offer free downloads of their manuals and software, so look around!

That was much more than i asked for, i didn't expect a post like that, thanks alot for your help and the links. I haven't clicked these links yet, but i'm sure they will help alot. Mainly i want this ecu to gain horsepower on a practically stock engine for now and leave the door open to forced induction. I have practically no knowledge in stand alone ecus and definately close to nothing about tuning them... again, thank you for your help.
