just have a question before i buy everything. i swapped my 95 gsr motor into a 96 dx. my motor is all obd1, and have a chipped p28 with the obd2a to obd1 jumper. i know i can't pass.


to pass is all i need is the obd2a to obd2b jumper, what ecu do i need to run?
2nd 02 sensor and ck trick? thanks guys

 

You could run an OBD2a P30 from a 96-97 Del Sol VTEC, but those are pretty rare. You could also run an OBD2b ecu from an EM1 or the OBD2 ecu from a GSR.

Check out this thread:

thanks, kinda was wondering if i could run a 99-00 si, just didn't want to buy it and it not run rite

 

You might not pass automatically because you have an older engine in a newer chassis. If NJ is as tight on this kind of stuff as CA I think you're done before you start.

 

ya we will see.haha

 

What's so funny? Why do you not call an inspection station and find out?

 

In PA, it will be fine as long as you convert all the OBD1 stuff to OBD2a (alternator, injectors, distributer, and ecu). That's what I'm doing for my swap.

The EM1 ecu will only work with an OBD2a to OBD2b jumper, I forgot to mention that earlier.

 

rather just do it and see what happeneds. thanks reed, i just picked up a 00 si ecu.

 

Jersey doesnt care what kind of engine is ur car. As long as your under the legal limit of emissions than you pass for two more years.

 

 

Why not just use an OBD2A p72?

 

what ecu would i need to pass inspection for my em1 with a 95 del sol dohc vtec swap? im in jersey btw

p.s srry for reviving such an old thread lol..

 

I guess your question has been answered, but you'd rather swap an engine than make a phone call?

 

This thread is from January I'm sure he did the swap without calling.

You'll want a P2T ECU from a 99-00 SI.

 

You are correct about the done before your start there marc

 

Just for future info for others reading this thread. a P2T will look for the FTP sensor.

This can be done to bypass it http://technet.ff-squad.com/code91.htm

Depending on your state though this will not get you through an OBD2 emissions check. While you will no throw any codes, the OBD2 system will not come online for the EVAP system. This is because the ECU will look for minor voltage differences from the FTP sensor, if you are throwing a constant 2.5v into the ECU it will not recognize this and thus the OBD2 readiness monitor will not turn on. If your state requires all monitors to be active your car will fail without a check engine light.

I bypassed this by using a P30 OBD2 ecu since the del sol did not have the FTP sensor. Also you can pull the sensor from an ex or si.

If anyone is searching and happens upon this thread feel free to PM me and I can try to help you get your motor through emissions, I had very little help while doing it and would be more than happy to help others.
