<~~~UTTER newbie!
I own a 97 Accord, with the F22B2 motor. OBD2. Soon to be 5spd.
I plan on running a T3 turbo with custom manifold, and piping. I plan on using an external Tial wastegate with FMIC.
From everything I've heard, I'll definately be running Hondata, and having it tuned by an accomplished Honda(ta) tuner near my city. I'm still in the process of reading (and processing) all the information from the Hondata website.
Question is.....what kind of Hondata setup will I need if I plan on running 8-10psi? I know I'll need OBD1, but that's all I know. What will I have to do with this ECU to make it work, and what about the wiring harness?
5th gen Accord turbo setup.

It WILL be accomplished!

You'll need to have an OBD-1 ECU socketed, and you'll probably want to run either the s100 or s200, depending on if you want extra features or not. I doubt you'll have to do any re-wiring...unless you are running low impedance injectors and require a resistor box [if your car doesn't already have one].

I will be running RC 310cc injectors, with AEM FPR, Walbro 255 ltr/hr fuel pump on this setup.
I'll need the ECU from a 1994-1995 Accord OBD-1, P28 socketed right? Socketed by Hondata.
My question about re-wiring was, if I swap to OBD-1 ECU on my OBD-2 Accord, will I have to swap out the wiring harness as well, or will my stock harness work?
On the S200 system, would I be able to use the base unit (295$) for running boost....or will I have to opt for the additional 200$ boost option?
Hypothetically speaking: I get the OBD1 ECU, send it to Hondata for socketing (65$ P28), and have it shipped back with the S-200 (495$ boost option) system. I can go from there to the Hondata tuner...and have it installed and tuned for boost?

Any OBD-1 ECU will work once it's socketed. Just make sure it has the features you require [VTEC, Knock, IAB, etc].
Your wiring harness will work. You will need an OBD-2 to OBD-1 conversion harness, and you'll need to make sure you have an OBD-1 distributor and are running proper impedance injectors.
If you are going to boost, you must purchase the boost option. There is no other way.
Once you get your Hondata in the mail, call your dealer/tuner and ask for a basemap. They should be able to supply you with a basemap to get you to the shop for tuning.
IMO, don't pay the shop to install the Hondata. All it requires is putting one chip in the socket in the computer , and plugging one wire into the ECU. It took me two seconds to "install" the Hondata, and my shop wanted to charge $65 for the "installation."

Just trying to estimate the damage.
OBD1 distributor? Off of a ealier model Accord right?
As far as injectors...I'm planning on running the RC 310cc (+) injectors. How do I go about judging the proper impedance?
I'll install all of this if I can learn what needs to be learned. I don't plan on jumping in without the knowledge. I know nothing about auto electrical, ECU's and stuff like that. I'm also ignorant towards the programming and tuning for boost...but more than willing to learn!

Do you know whether or not your car is equipped with a resistor box? If it is, you use [and need to continue using] low impedance, or Peak & Hold injectors. If you do not have a resistor box, you are using high impedance, or saturated injectors. If the latter is the case, you can run either type of injector, but if you decide upon Peak & Hold's [low impedance], you will need to wire in a resistor box.
Another way you can test impedance of an injector is to take an ohm meter and put it across the terminals on the injector. A low impedance injector will have a value around 2-3 ohms, a high impedance injector will have a value around 12 ohms.
What really decides what "impedance" of injector you need is the ECU that is driving them. If you use an ECU from another car for Hondata, find out what kind of injectors came with that ECU, and use/don't use a resistor box accordingly.
Yes, an OBD-1 distributor will be from an earilier model accord [just don't get an OBD-0 distributor...it won't work].
I'm the same way as you...I won't do something unless I understand it. The only exception is tuning right now...I'm going to let an authorized dealer tune my car, because I want expertise in that area. I still understand the basics of tuning though, and hope one day to learn to tune myself.
