A buddy and I are in the process of getting his 84 GSL-SE back onto the road, and among the numerous items on the to do list we will be pulling most, if not all, of the emissions equipment.

After much searching I have yet to find anyone that has posted an emissions removal guide for the fuel injected 13B in the GSL-SE. Ive already done a similar removal on my FC, and figured this would be about as easy. However, after reviewing the vacuum diagram, i'm having a hard time figuring out how to reroute the essential things, IE the two nipples coming off of the distributer, and possibly keeping just the BAC valve.

Any input/help would be appreciated.

 

I need info on the same thing....since i also want to remove all my emissions on my GSLSE.

 

There's not a lot to it. Much of what you see are solenoids and vacuum lines to control the advance, BAC, and other hardware that aren't typical "rat's nest" items. You no longer have an AAB setup (ECU just cuts off the injectors), a purge valve for the A/C blip (BAC does that for you) and other hardware's been obsoleted.

Replace the main cat with a test pipe or presilencer, make some provision for the aux ports, if so inclined, remove the airpump, and block off the ACV. There's not a lot more to it than that.

 

Yeah thats what i was thinking....already gutting the cat, removing the air pump, and blocking off the ACV....thanks for the help anyways!!

 

most of the stuff in the rats nest place on a gsl-se, isnt smog stuff, its just the bac and vacuum advances, which you want to leave alone.

 

You mentioned No longer having an AAB, ECU just cuts off injectors. Could you elaborate?
We have the ECU hooked up, all inputs, voltages and grounds appear to be present.
We have fuel pressure. We have signal return from the trailing coil's igniter, square wave 0 to 12 volt pulses.

We have no grounding of the injectors at the ECM, (no injector pulse.)

We've induced codes by unplugging AFM and trailing coil igniter signal, and the ECU reports it.
Any ideas?????
