ok i want to get hondata boost setup for my sohc turbo project in a 91 hatch. i know i have to convert to obd1, here is my question
what ecu, distributor do i need? i know where to get the obd0-1 harness so thats not a problem, im doing a d16a6 so there wont be any Vtec involved. and i do have a 94 CX ecu and distributor laying around will they work?

thanks and merry christmas

 

anyone?

 

You don't have to convert to OBD1. You can use the Stage 2 or 3 with OBD0. The s100 and s200 systems only work with OBD1.

 

im staying with the d16a6 not dohc vtec, i want one that has the boost option

 

anyone else?

 

You can use an OBD-0 ECU from a vtec car (JDM integra xsi or crx siR) and hondata 3b it. OBD-0 works with boost, but not datalogging. Just because the ECU supports vtec doesn't mean you have to use that feature. I'm sure you can get the PR3 or PW0 to work fine with your sohc non-vtec motor.

If you want to convert your car to OBD-1 for hondata, you might be able to use a non-vtec ECU from a DX or something. Hondata's website should have information on this. You might want to check there or call them.

yea i want data logging, i have a p05 i think it is, CX ecu i wonder if that will work

 

You can use a PW0 or PR3 for ALL your needs. Datalogging, 3 bar map sensor ect.

You just a have to use the 'older' version of their software. Not a big deal.
All the features you need to tune the car properly are there.

I tuned a PW0 on a '89 JDM B16A turbo to 333 whp. Piece of cake.

Hondata's website lists what ECU's they work with.

So you can datalog on an OBD0, then?

 

so what hondata setup would i use with one of these ecu's? i just want to be able to tune it , and i want to be able to datalog

 

you can datalog sensors with an obd-0 ecu but not the o2 sensor specifically. at least thats what I and a few others with obd-0 hondata setups found

 

so what does that mean?

 

it means there is a ground loop problem somewhere in the factory wiring that causes the ecu to get false readings from a wideband. subsequently making it very difficult to log a/f ratios v. thier position on the fuel map.

 

so whats needed to solve this? i want to be able to tune it the best i can,
is it gonna be better for me to go obd1 or stay obd0? i want it to be the best i can get it

 

I got fed up trying to figure out a way around it but decided to use the aem ems instead. it has a gain function that allows you to manipulate what the ems reads as the actual voltage coming from the wideband. true and I think it was slowteg had the same problem as I did and I don't know if they have figured it out.

 

i think im pretty sure im going obd1 and sticking with hondata, im sure it will be worth it in the long run

 

You can use either, but tuning will be much easier with OBD1. Give me a call on Monday and YOu can get enyother questions answered. Number is on our website.
