i want to convert my obd2 to obd1...every one says do it but no one as told me the advatages of going to obd1... will it increase hp?i heard it was better for nitrous and turbo true? also what sensors will obd1 eliminate? and i am not sure but is the obd1 ecu like pr3, as in can you read the code the engine is throwing from the ecu? thanx

 

I currently have a Skunk2 obd2>obd1 harness and a 95 GSR ECU. I ran in on my '99 GSR with a I/H/E and ignition system. It made no change in my 1/4 mile times. The car did run richer. I would suggest waiting to do this with at least CTR cams and increase air flow, higher compression and a VTEC controller. The other plus is with the obd1 ECU sometimes it is cheaper to get new programs.

 

how much did you pay for the harness??

 

only do thi if you want to use something like hondata ro raise your redline/change timing. you can alter your fuel with an afc (yes i know hondata is better).

 

Sorry but I had a quick question I bought a Honda prelude 99 and it all ready had a hondata in it and switch everything to obd1 is it possible to read it with the scanner and I believe the port is still an obd2 port could that be a problem

 

you plug the s300 into your laptop....it comes with a usb cable. if you want it to function like a obd2 car remove the s300 and put a stock ecu in, either way this is the WRONG section and you bumped a 13 year old thread. the info in this thread is so old it's a joke.

 

My bad I've just been looking every where and the guy I bought it form never gave me the cord and pretty much rat fucked all the wiring Im going to buy one thou I just got a ticket for not passing my safety inspection so I was just hoping there was a way beside buying another ecu

 

the cord is a "type b" go to Walmart and get a usb "A" (regular port)to usb type B google that if you don't know what they look like. it may not actually be a s300 rather a junk ecu running crome(old school junk) check that then see.... the s300 unit can be sold for around $500ish.

 

Thanks bro much appreciated
