hey everyone,

i'm going to retry my smog (california, of course ) this weekend and would like some opinions.

i passed the NO and CO sniffer part on Low and High, but failed the HC part by almost two times the allowable. my timing was set to 16 BTDC and my car wasn't running very hot.

i'm pretty confident i can pass (as long as visuals is cool ) but i'm wondering a few things:

1.) i have a HKS filter on the motor now, and last time i took it off in place of a factory air box and reset the ECU. is this advisable?

2.) when i reset my ECU (if advisable) , should i romp on the pedal or cruise gingerly? what would make my car run leaner and burn better at 15 and 25mph during the sniffer test?

3.) since my timing was 16BTDC, could i adjust the timing through the distributor even tho' its an OBDII motor? i thought my ECU automatically adjusts the timing as effecient as possible to prevent knocking?

4.) are there any products you stand by that would clean my injectors, knock away carbon deposits, etc? do you even think its necessary since i got my engine rebuilt not even 3500 miles ago?

5.) i have standar copper NGK plugs and i know my motor (96 GSR with P73-A0 pistons) usually uses platinum tip ones. would this make a huge deal cause i thought copper plugs burn a bit cooler?

thanks for all your input!!

You should be able to adjust base timing with the distributor. Your ECU only advances timing (makes spark occur faster) as your engine turns faster. Base timing affects where the spark actually occurs. The ECU only retards timing to prevent knocking whenever the knock sensor sends a signal to it.

4.) are there any products you stand by that would clean my injectors, knock away carbon deposits, etc? do you even think its necessary since i got my engine rebuilt not even 3500 miles ago?

I've heard good things about the Berryman 3-step fuel system maintenance kit. It cleans your fuel system, carbon deposits in your engine, and air intake system. They have it at Kragens for $20. If you had your engine rebuilt that recent then it's not necessary at all. If you want to burn a little leaner, widen your spark plug gap for hotter spark.

Good luck.

 

If you reset your ECU then you need to drive the car normal at different speeds braking and getting on it to have it run all test accordin to a friend of mine not all test have to be run but all but maybe 1 or 2 pramiters don't have to be run to pass the OBDII scan test since it is just a generic test

sweet. thanks!!!

anyone else?

 

tip the guy $40 :rick:

 

:hahano: knowing my luck,

they'll give me a :nono: followed by :slap:
