It could just be how you're driving it. I put one on for a customer and when I drove it, it seemed like the quicker I kicked the clutch the better it worked. I had it on 175ms also but I believe with some practice it would work with less (150 or so).
Emailed Jon and he advised me to put it on auto and give it a try. I put 175 per recommendations in this forum but I'm guessing they're experienced...unlike myself
Wasn't too bad. The hardest part was splicing the wires to the PCM connectors and the ignition wire under the fuse box. The wires on my car didn't have a lot of slack so I had to solder in a tight space. Everything else was simple.
So...
I guess I'm a REALLY slow shifter. Set to Auto and it's working now. Love the thumping sound with each shift!! I'm doing my best to shift fast but I guess it ain't fast enough. How the hell are some people shifting so fast that the 175 setting is working for them????
