OBD2--->OBD1
 

ok so i just picked up a new ride 00 civic si. got rid of the turbo rex :-[ ive always been single cam turbo obd0 so this is a switch up. anyways basic question is converting the car from obd2-->obd1 are there any typical gains from just doing this alone. (besides the fact of all the better tuning capabilities) do you actually gain anything from just converting over (all motor) i know i need the harness but is there a certain ecu i need like p30 or someshit? i know i sound like a noob but ive never been b-series. ---- anything turbo D i know but this ---- i feel stupid :S

YES SOON TO BE TURBO>>>

Re: OBD2--->OBD1
 

Are you seriously asking if you'll net more hp from an obd swap?

Re: OBD2--->OBD1
 

yes you will gain exactly 3.14159265358979323846 hp :P

Re: OBD2--->OBD1
 

when i switch my obd2-obd1 i gaind about 100 whp becuase i could finally boost retard

Re: OBD2--->OBD1
 

You dont have to run your 2 o2 sensors and you can disable and put features. Plus you can program your ecu. So yeah you can gain Hp from that switch.

Re: OBD2--->OBD1
 

oh ---- nevermind i know i wont gain horsepower!! that wasnt necesarilly my question but i guess i worded it wrong.... HMT aint what it used to be..... bunch of pricks i've been a member since god knows when i ask one question and boom nothing but flames what happened to everyone helping each other and giving advise..............

my main question i guess is there a particular ecu to use when going obd1 or any chipped obd1 ecu with a stock uberdata/chrome etc map should work

Re: OBD2--->OBD1
 

THANKS FOR THE DECENT STRAIGHT FOWARD REPLY THATS ALL I WANTED TO HEAR

Re: OBD2--->OBD1
 

Technically I would suggest you run an OBDI ecu that has a knock board.

Re: OBD2--->OBD1
 

do u gots to change the dizzy too when going obd1?

Re: OBD2--->OBD1
 

No

EDIT:

odb1 ecu and a conversion harness which is 50 bucks or so.

Re: OBD2--->OBD1
 

No, it's unlike switching from OBD0 to OBD1 where you do have to do that. You only need the OBD2B-to-OBD1 jumper harness and an OBD1 ECU, most popular being the P28 from '92-'95 SOHC VTEC EX/Si's with a program of choice (chrome, neptune, custom, etc..).

As imburne mentioned, you bypass the secondary O2 sensor at the cat. You also bypass the air intake sensor on the intake pipe and I believe a secondary oil pressure sensor.

Re: OBD2--->OBD1
 

Where? Cheapest I can find is Katmans jumper harness, which I think is like $70-$80. :-\

Re: OBD2--->OBD1
 

ebay nogger.....or just make your own with xenocrons do it yourself kit...

Re: OBD2--->OBD1
 

FANX JOE!!!! 8)

Re: OBD2--->OBD1
 

ill make you a harness for 50 bucks

Re: OBD2--->OBD1
 

Why in the hell would anyone what to do that??

Re: OBD2--->OBD1
 

disable
disable
disable

Knock Knock whos there?
