I've searched for a few days now and can't seem to find exactly what I'm looking for so here's my question:

I have a boosted obd1 gsr in my 99 Si w/chipped p28 and the scanner can't connect to it. I know it won't connect because of the jumper harness, so what can I do to get it to pass emissions. I do have a p2t ecu also

 

you have to run the stock 0bd2b ecu p2t which you have, you cant run the obd1 with jumper. now once u hook up the ecu your probably going to throw a cel for the crank flucuation sensor seeing as the motor is obd1 so do this (http://www.ff-squad.com/technet/ckftrick.htm) and make sure your running stock injectors unhook the charge pipe and just run it normal for testing

 

Yea, you would want to run an obd2 ecu, they burn 19 times cleaner emissions than obdI ecu's

 

So I can use p2t with my gsr? And get stock injectors and disconnect the charge pipe from the turbo and the cfk bypass

 

yup then u should be good, make sure to have o2s plugged in any cels post them up
