I have a 1985 honda civic si, has obd0 ecu that has a socket already on it! I have blank chips, chip burner, ostrich 2.0, etc just dont know how to tune it! Please help!


Im running a t3t4 turbo, 450cc injectors, garrett bov, obd0 ecu, any help wil be awesome

 

I was told its a d16a1, and then an other person said it was a b16a1....ill have to look

 

first you'll have to find our if you have a d16 (1 cam) or B16 (2 cams). then since your still using obd0 ecu, you'll need to to use Turboedit program to create a basemap for your motor setup.

JD TUNING

 

Turboedit if using a non-VTEC ECU (PM6, PG7, PR4, PS9). If using a VTEC ECU (PR3, PW0) you'll tune with BRE.

 

Ok, the motor is dohc, and rite now its pushing around 10 psi! So i do not need a new ecu or anything to start tuning?!

 

You hook up your ostrich to the socket.
Hook up a wideband.
Get a friend.
Friend drives while you are on the lap top with the ostrich hooked up.
You watch the AFRs and change the fuel map according to your target AFR.
Eventually you get the AFRs knocked out.

Ben has a write up on how to use BRE. I'd suggest reading that.

Good luck.

 

I have the wideband system complete hook up installed

 

Most of this has been thoroughly documented on PGMFI.org, so you can read through their forums to get a hang of it.
Although Crome is for OBD1, many of the principles are the same so it may help you to read the manual in my signature also.
