A buddy of mine will sell me a da/ef9 spoon vtec controller for really cheap. I have searched and found inconclusive evidence of wether or not it will work on a simple d16z6. I imagine it will but only because vtec controllers tend to be interchangeable. Please enlighten me. It is the usual spoon controller with a ****, red led, and black rectangle backing as Many of the ef power switches use (sunroof, fogs, etc).

^vtec solenoids not controllers, i apologize

 

This one? Works if you have OBD1 conversion.
Question though - does the Spoon controller adjust fuel maps?
If it doesn't, then it's pretty much worthless.

 

I'm pretty sure that's the one. There's making on a white box that says spoon then under it I'n big letters "vc-3e" if that doesn't help can you post a picture of the on that doesn't adjust fuel maps. Could you also tell me a little of where it plugs (into ecu, etc) and if it just adjusts when vtec kicks in or the fuel for each rpm rage or idk sorry. Lastly about what's a good price to pay? He was gonna throw it to me for right around 120$ and a big Mac. Thankyou for the help btw.

 

This is what Spoon's functional description for this device is
"This is very useful for course racing where slow tight cornering is common and the need for a quick vtec engagement is necessary to help pull you out of the turn. The Spoon vtec controller is available for 92-95 EG Civic."

Using it for cornering makes sense in changing the vtec point a little lower to maybe 5000~5200 rpm.

What I have read is that the Spoon controller only adjusts the RPM point that vtec kicks in without allowing any modification of maps.
That works alright on a stock engine, but then again on a non-tracked stock engine you don't gain much of anything by changing the vtec point. In fact, you -can- actually lose a lot by just changing the rpm point that vtec turns on. Engaging too early -may- give you a lean condition and if it's excessive the motor will bog as it sucks in too much air for the too little fuel. Engaging too late has you riding the primary cam lobes longer so you feel vtec 'kick in harder' (insert riceboi pic here), but at the loss of overall hp since the vtec lobes could have been providing more hp during the time the primarys were being forced. Vtec is meant to be a nice smooth transition.

The Fields, VAFC, etc do this AND allow for some map tuning. This is the way to go on a modified engine if you must go with an piggy-back unit rather than an dyno tuned ECU solution. Even using a piggy-back solution it is suggested to have a dyno tune to get it all working at its best.
