Ok so I now have an obd1 ecu socketed and chiped but in my 91 da I bought the jumper harnis and it came with the extra outlet to plug it into my laptop. It's a 12 point and it has the one end that's sapose to goto the computer on it? But it's just the wires I can also in clip it and maybe plug one that goes from that to my laptop

 

Bump

 

What!?

 

lol theres a cord that comes off the harness that the vafc can plug into but someone also told me i can tune my ecu through it to i just have to get the cord that goes to the computer

 

neva heard of harnesses plugin into a laptop but if the ecu u have is obd1 and u have a DA u shouldn't even need the jumper if ur integra was 96 + it would be a diff story

 

It's a 91 so I had to jump it to obd1 insted of obd0

 

It is pointless to connect the cn2 header to a usb or serial interface to datalog unless you have the proper software to datalog & tune with along with the hardware to emulate live to the ecu.

You are better off buying a Hondata s300, neptune rtp or ectune rtp system which includes all of the hardware/software in one bundle.

Even after purchasing all of the hardware/software you still need a wideband oxygen sensor gauge along with tuning experience to really get everything dialed in properly.

You are best off taking the car to some one who does it every day to have it tuned.

 

check JDMshit - Performance Parts & Accessories Supplier they got all kinds of shit for obd1 to obd 2 and what not
