In Reply to: JC/TMS chip pinging...due to California Gas? posted by Barry Robinson on July 17, 2001 at 16:12:24:
I had thought about a JC chip as it seems to be THE chip. In talking to people it also seems that the So.Cal. gas is just not good enough and pinging is the result. According to Hoa that's what he has seen. Give him a call. I've got his number if you need it.
Okay guys, I know a few of you have had pinging with the JC/TMS chip, even with 92 OCT gas. I swapped the chip out and went back to stock. The pinging was gone and the car ran cleaner (failed first smog test w/JC chip and passed the second w/stock chip). I'm just wondering if EVERYONE is experiencing this pinging or is it just those in SoCal. I'm going to swap it out for a Dinan chip to see if it still pings. This pinging side-effect isn't worth the 2-3 extra HP it has over the Dinan.
