Monsterbishi Posted October 23, 2020 Report Share Posted October 23, 2020 A quick question, can/should I drive the VTEC solenoid on a early 90's Honda directly from the ecu, or should there be a relay in the equation? From what I've seen online they have a fairly low current draw? Quote Link to comment Share on other sites More sharing options...

Adamw Posted October 24, 2020 Report Share Posted October 24, 2020 They need a high side drive, so, if you have a Storm, Xtreme, Fury or Thunder wire-in ecu then yes you can control directly (Aux 5/6/7 or 8 can do high side). Anything else will need a relay. Quote Link to comment Share on other sites More sharing options...
Monsterbishi Posted October 26, 2020 Author Report Share Posted October 26, 2020 It's a Storm, so direct wiring it is then :-) Quote Link to comment Share on other sites More sharing options...
