DIY Rev Limitor

Does anyone know a link for a Do It Yourself Rev Limitor? iM on a budget and i was wondering if anyone knew what you could use to make one and where to wire it to? any help would be appreciated, thanks.

rev limiter. y do u want to make one ur car already has one

no mine doesnt, for some reason when they programed the ecu, they didnt put one in

mayb its at a higher rpm then what uve taken ur car at. teh only way to get one is either by getting ur ecu reprogramed or getting a new ignition system like msd
