I want to get an actual o2 simulator. I bought the 02 sim from zpi racing it is suppose to be the smart 02 sim. Who has one installed that hasn't set a CEL? Mine worked for 10-15 miles then code set H02S low voltage. Who has the 02 Sim in their car and it has worked for at least 50 miles or longer. I don't want the anti fouler trick either. The sim helped out power while it worked b/c the CEL wasn't on for a little while. Thanks for any help.

 

Check that your ground wire is properly installed. I got a low voltage code with mine because of a bad ground. Moved the ground and never got that code again.

 

I used a fluke multi meter to determine the best ground and lowest resistance.

 

hey nick and anyone else who is getting the "low voltage" code, give us a call at the shop, we are hearing this problem with the last 5 or so 02 sims that were shipped out...we're looking to send that batch back...(502)371.RACE

 

Thanks! Your customer service rocks!!!
