Default k20a2 rpms limited to 2k help

hello i have a 02 em2 with a k20a2 swap. Today i was on the way home from work, when i got on the highway i pulled thru the gears and in 3rd at about 6700 it fell on its face. I pulled over and checked gauges, i then atempted to pull away and it now it will not acc past 2k rpms. I got no cel from this and i drove about 10 miles after the problem occured. i have hondata that i realy dont much about but after i limped it home i pluged in the laptop and i dont c anything but when i do go over 2k the inj voltage drops. i checked the oil and looked for any wires astray but nothing. If anybody can help it would b nice. thanks.

why not save the map you have and try using another map? see how another base map may work.

why don't you try putting the stock ECU back in, letting the car sit, while on for five minutes and road testing it.

If ur tps isn't hooked up or broke, your car will run fine, but wo't go passed a certain RPM, it's like a rev limiter. If your tps was broke or the plug was, swap it out, calabrate it and try that.
