So yeah, just like the title says I have a B16A in a 90 CRX, its already been all wired up and is running fine but I'm going turbo and purchased a S300 hondata, only to find out that my cars still obd0....seller had explained that it had been converted to obd1 but it really wasn't. I've had the car for a while now, just been doing a full interior strip and rewire, ready to move to newer technology tuning. I know this has been covered, but what ALL needs to be bought to switch it over to obd1. I have a p28 awaiting a trade for my PR3 but I know the dizzy and a few other things need to be switched. Is there a write up covering everything? Thanks....Nothing is as simple as the carbs of the past...... :[

 

I use the boomslang obd0-obd1 conversion kit and they have a step by step guide for installation. Really easy and <120 bucks.
Here's the page and installation guide: http://www.boomslang.us/obd0to1.htm

i bought the whole rywire kit for 190. it includes the ecu conversion harness, distributor adapter harnesses, and an engine subharness deal so you can plug in an obd1 o2 and everything else. still havent installed yet, but it looks very professional and clean.

The original and still the best.

You will need the following FYI:

OBD1/2 distributor, 0-1 conversion harness and OBD1 ecu. You do not need to switch to OBD1/2 injectors and if you are getting it tuned, you can turn off the 4 wire O2 sensor so that you will not need one. Also, if you are using AEM, you can run the pre-OBD distributor..(saw you are running Hondata so you still need the OBD1/2 distributor).

If I just want to tune the car with the current setup could I just do that by adjusting the fuel pressure??

B16A OBD0
CAI, DC 4-2-1 Headers, 2" Straight pipe to side exit, gsr cams...

it just seems to be chugging down the fuel and it spits the unburnt fuel out the exhaust

 

Tuning is not just fudging with the pressure, theres lots more to it then that
