I finally have my car running 100% and was thinking of getting a a chip from ESL. The last time I talked to Andy at ESL he suggested I get something to monitor knock before installing the chip and I plan to follow his advice. Ive also heard a lot of people saying they are unreliable/useless so I guess what I want to know is if not knocklink what should I use? This is for my 94 EJ20g.

Thanks,
Garrett

look at the j&s safe guard

saving your engine vs showing you that it is blowing up
