Most of the recent posts leave out information pertinent to solving the problem.

I have a k20a2 93 honda civic coupe

oh yea for some reason my datalog screen freezes while im recording and datalogging about 15 secs into the run, i told you guys it was messed up

The 3000 rpm problem is because VTEC is set to 3000 rpm - which is very low for stock cams. Yes, I know the k20a2-rsx-310cc-todahdr.kal calibration has those settings. Try using k20a2-rsx-stock-tuned.kal to start with.

If datalogging is stopping first check the spark plugs are resistor type, then go through http://www.hondata.com/techk20swapgrounds.html and check you have all the grounds - most people forget the ground on the timing cover side. Also pull all the grounds wires off and clean the contact faces down to bare metal.

thank you!!! seems like your the guy to talk to on here
