I need big time help with an issue.

my car isn't revving past 6800...at first i thought it was a vtec issue, and as it turns out it isn't. It revs to 6800 even in neutral. motor is 00 euro r h2b in a 93 bubble so i did the obd2b to obd1 engine conversion. i'm still using the obd2b dizzy and i'm pretty sure its wired correctly. i have no idea what could be wrong.

i have no cel
oil is good
timing is good
ecu is good, its a p72 on s200 btw.(tested it on another car and revs out fine.)
compression is 240 across the board.

i've searched for 3 days before i posted this. all topics lead to nothing, and nothing has a resolving problem. any leads would be great, thanks.

i cut j1 to see if my map was [freak]ed, but its not. revs to 6600 or so, put in a ls computer and revs to 6000, it cuts me 1000rpms short. why?


** EDIT ** forgot to mention that it runs dumbbbbbbbbbbbbbbb rich, like i see the needle going down as i press on the gas, i don't know if its running weak cause i never had a chance to fully drive it, but it does feel very strong. i know this is a limp mode act that it put inseld into but i have no idea what set it off.
