Has anyone ever gotten this to work using the VTEC feature. It must be doable if people have used the SAFC in the past. I just can't seem to get a signal from the e-manage. Is it possibly I need a VTEC in wire? There is also a VTC lead that I do not have hooked up. Any comments are appreciated.

 

does it work by ground or positive signal? im assuming you checked for signal using a digital multimeter?

 

Best thing to do is acutate the power valve with an RPM switch...then use the emanage to activate that using the vtec feature

 

I believe it's by power, but I could be wrong. Guess I could try checking for a ground switch. And yes, I'm checking for signals using a multimeter.

AMG,
Don't quite get what you are saying?? I was planning to use the e-manage to activate a solenoid to switch the valve. the whole point behind using the e-manage is so I don't have to fork out the 50 bucks for the RPM switch. All the cash I had to dish out on this project anyway It really doesn't matter, but now I'm just plain on a mission to get this to work.

-Any chance I need a VTEC in signal to make the circuit work? (due to the way e-manage operates)

-Anyone know what VTC is?

-Can anyone tell me how VTEC is electrically activated in a Honda? (Is it really just one wire)

 

What is your setup? 3.5 swap?

 

No, way simpler. I'm just putting on a 00VI on a 4th gen, and trying to use e-manage's VTEC function as the RPM switch. Then I can switch it from a screen in my car, change it, disable it, whatever I want through the support tool.

 

Im not sure how VTEC actually works, but it sounds possible. However, knowing greddy, its not a plug and play deal.

 

Im pretty sure the signal for the VTEC is one wire, as teh VAFC is a one wire signal...

Theres probably something you're missing when setting up the unit if that wire is not getting any signal....

 

IIRC, there is a harness for it

 

It sends a positive signal (on my VAFC) so you have to ground the VIAS solenoid and have the power hooked up to the e-manage. They may have different ways for activation it like low, mid, and high ranges (thats how it is with the VAFC). Just have read the manual and play around with it until you get it working.

 

i saw the injector/ignition/and pressure sensor harnesses but nothing for VTEC/VTC..

According to the manual theres a VTEC output wire(yellow) and a TEC input wire (light blue)

wtf is a TEC input?

 

ALSO did you do the VTEC SETUP procedure described in the manual? You have to change a few jumpers.

 

Only the Emanage Ultimate can control VTC (vari timing chain)

 

Yeah, it's part of the main harness. I'm going to yank it out again, double and triple check my jumpers, then double and triple check my wiring. The software is pretty straight forward. Basically just check the box for VTEC and input an RPM to activate at. I'm guessing it will activate even in Neutral, I'll try driving if I still can't make it work. Thanks everyone for the advice, if it doesn't rain, I'll work some tonight on it.

 

Well, I'm totally fricken baffled by this d@mn e-manage. I get a constant 0.6xx volts from the vtec out wire. I've tried pretty much everything I can think of, and about to just give up.

 

I made a discovery that the VTEC in signal is reading "HI" meaning VTEC is on, but the output still says "low", and I can't get it to switch to high. I'm wondering if I do need to ground out the input or send some kind of voltage to it??

 

Nothing has worked, I'm done wasting my valuable time on this.

 

Damn.. I was keen to give this a go actually. I have an emanage blue I wanted to use for my MEVI activation but now that I look at this, i've been put off :P

Unless.. of course you did manage to get this to work in the end??????

I hope so :P

 

I'm pretty sure I've read that a select few people have pulled this off. Sorry, don't remember their screen names. Keep searching and reading until someone chimes in!

 

searching i've done - google and here and nothing conclusive has come up. Fingers crossed someone chimes??

 

seeing if these guys can help at all...

AFAIK the EB should be able to activate the power valve. I'll check into this later tonight.

 

Thanks DandyMax - If you have any ideas let me know. It seems nobody knows and i'm ultra keen to get into the garage this weekend and do it. My main question is - which wire activates +/- 12v DC on activation? Someone mentioned the VTM wire. Does the emanage draw its current off itself for the activation? Or does it require a relay?

It's weird because there are three wires for the VTEC function.

1) VTEC IN (Yellow Wire)
2) VTEC OUT (Lt. Blue)
3) VTM Out (Purple)

VTEC IN seems primarily used for getting signal/voltage from a Honda ECU
VTEC OUT seems to reroute that information back into its original destination from the ECU
and VTM seems to be on its own?? Does VTEC use two wires to activate different stages of activation?

I'm confused about this..

Referring to the image below - I think this is how it's supposed to be isn't it? I cant seem to modify the ON/OFF values, just the RPM and throttle position..

I've set it to activate at 5,300rpm - but throttle position doesnt particularly matter in this instance so i've put in some low values



Ceasar tells me you were in NZ and AU not so long ago - he even told me I should meet up with you and pick your brains on a couple of things - maybe next time huh?

Many thanks...
