I have a 96 obd2 gsr engine in my 92 cx. i'm getting a check engine light and i know its because i hacked my wiring. well anyways i'm getting it professionally rewired and my question is:
is it better to have the obd2 engine wired for my obd1 computer, or rewire it so i can use my obd2 computer.
is there anything special i need to know
thanks

to save myself from all the problems I just bought a hondata. It just seems much easier to do it that way.

my .02 cents

 

Buy yourself a usdm P-72 GSR Obd1 ecu. It plugs right into your cars wiring harness. Its easier than trying to use an obd2 ecu in an obd1 car.

 

thats whats in there now, an obd1 gsr computer

 

i know this sounds mad newbie, but what the hell is a hondata

 

Hondata is a standalone ecu. I have a 2000 b16. I am wanting to put it in my 90 std civic. Should i switch to an obd1 ecu or obd0? I have been told it is too hard to use the obd2 ecu in my civic.

Hondata isn't exactly a stand-alone. It's a modified Honda ecu with several very usefull additions. It gives you the best of both worlds. The Stand-Alone versatility and the OEM reliability.

As for your set up. Get the wiring fixed and use an OBD1 GSR Computer (or a Hondata modified one) That will be the best for taht particular engine. The Hondata will allow you to change various parameters as you modify the engine so it's a worth while investment.

If you can't get an ODB1 P72 to run right, adding a Hondata on top of it is just going to multiply your headaches.

 

JDM:

I also have an obd2 motor with an obd1 ecu.. I dont have any driveability problems at all. The car gets 32 mpg mixed driving. I have an obd1 JDM ecu, the mileage is about 3 mph less. If your car is running fine, then leave it alone or chip your ecu.
