Guys,

I'm currently running mt ITR without the VTM wire from the V-AFC, to install this and get Vtec back do I wire this to the empty socket on the plug like it says in the updated manual or has the real VTM wire moved to another location on the plug as I'm having problems trying to get a wire into the emtpy socket. I can't beleive how tough it is getting the wire to stay put, I got the smallest screwdriver in the shop and I'm still straining it try to do this.

 

i have no idea wtf your trying to say .

good luck. http://www.apexi.com

 

LOL!! Christ! what I mean is, when you wire up the VTM wire to the plug do you wire it to the empty hole (think it was pin 21 ir something as stated in the manual) or is there already a VTM wire I can splice into that's not stated in the manual.

Thanks.

 

All you have to do is cut the VTM signal line on the harness and tape it up! U don't need to connect it to anything.

 

That's the problem, there is no VTM line for me to cut, I've got no vtec now y'see

 

"Sigh!" I'm going to stick the VTM line from the V-AFC into the spare hole on the Blue ECU plug tomorrow if nobody stops me, I hope it's correct........................BBOOOOM!

 

Does this help any?

I'm currently trying to install a V-AFC also, and here's what I've found thus far:





If anyone sees anything wrong on these charts PLEASE tell me!

Thanks!

 

Yeah I got a copy of this already, you see where it says VTM? There's no wire for me to splice I was wonderind do I stick the VTM wire from the V-AFC into the hole marked VTM on the diagram.

If so how, I can't the wire to stay.
At last someone who knows what I mean! Think I'm gonna cry!

 

soup- You're an ***. If you can't help him, don't make rude comments like that.

To the original poster. The diagrams say that some cars don't have that vtm wire. For example, that's not one of the required wires for the install on my friend's obd2 gsr. On the other hand, some people do reccomend that you install it anyway. Go to radioshack or bum some spare wire from a friend and run it from the vafc to the connector. Don't know if that helped any.
If your vtec isn't working, maybe you should check all your connections.

Read the manual....on some cars its not required to hook up the VTM wire. Just make sure all your connections are right and are tight.

 

I'm sure Soup's just messing, he's cool being one of the Vets here.

Back to the problem though, are you saying a 2000 ITR dosen't need the VTM signal? I've read elsewhere that without the VTM there's no Vtec due to lack of oil pressure or something, but I can't understand where the real (original) VTM wire is, I'm not sure if it's just another wire in the plug or located elsewhere

My ECU looks like WH-2 in the diagram you posted above

Read!

Your ECU is WH3 if I am reading the chart that Tom posted right. 99- B18c5 is WH3. And No sticking the wirre in an empoty hpoel is the silliest thing I have ever heard.

Unfortunately if you used WH2 to wire things up you need to start all over.

 

correct Trey. its simply on the chart

only to make sure of...is that your UK itr is the same as US as far as ecu's and plug similarities which i'm sure it would be

 

Hate to be a pain in the *** but WH-3 is not my ECU, mine looks exactly like WH-29 (with the second ecu plug missing)

The car starts, runs and I'm getting all the readings from the V-AFC but no VTEC, now assuming I go with the WH-3 diagram, that means that the VTM wire should go in the top right hole of the 31P (Blue) ecu plug, I've tried it and still no VTEC.

I wired the VTM wire from the V-AFC to the wire I had spliced (the blue and white wire) but nothing happenede after setting the vtec for 5000

Somebody please help, I'll never play with my ECU again!!

What color is the VTM wire? I've tried and Blue and White already as stated in WH-3. Somebody pppurrleeasee!

 

You should really try to find someone that has done it before it sounds like.

That may have some insight for you but it is on a 2000 Civic SI. Read for reference and insight.

Did you solder everything?

 

No it's taped up, that link you post dosen't say what's he done to the VTM wire.

Thanks anyways

 

We left it disconnected at per the instructions. The update says connected only if there is a problem.

Also the diagram above shows where to connect it.

I still don't know why you don't think the WH3 is your ECU.

 

Couple things. first off....vtm wire disconnected doesn't mean vtec won't be activated. second...what is a WH-29? are we suppose to round that up to WH3 or just accept the 2 and not the 9?

Are you sure everything else is hooked up properly? its possible its simply not wired correctly with the right diagram.

 

WH3 might not be his ECU actually. His car is EUDM.. I have no clue which ECU/harness they are using over there

I'd check your other connections as well though and make sure you actually hooked everything else up correctly.

 

Good advice.

Would EUDM not have the same harnes ad JDM and USDM? I mean Apex puts the instructoins out for all ECUs? I supose it does say B18C 5 not 6. Hrm.

For those who wonder, the quoted reply is an example of post whoring. While it is an intelligent post, and very helpful to the situation, it was made to post *****.

And yes, this post was too

 

Dude...If your ECU is WH2 then its the same as the EUDM ECU. It SHOULD have VTM signal wire on the ECU harness. You said u wired up everything else but the VTM...so does the RPM work? Are you getting throttle signal and rpm signal readouts on the display??

I think you might have wired them up the opposite way. Are you sure you're looking at it the right way? Don't forget the wiring diagrams shows the actual pins on the ECU and NOT the ECU wiring harness, so when you wire them in all connections have to be reversed. Makes sense?

 

OK I'm back, yeah I am getting RPM and pressure signals but testing this today there is one problem, I was thinking maybe it's wired up correctly but I'm not driving fast enough to activate the VTEC, I set the VTEC to 5000RPM, and drove the car past 6000 - nothing happened, I looked at the recorded RPM on thr Apexi and it read 4444RPM, I think the 2 tachos (on my Teg and the one on the V-AFC) are too miss matched, I 've been through the manual but never really understood how the rev calibration worked, at low revs there a little difference but the higher the revs then bigger the difference is. How do I calibrate this so it's more accurate?

Yes WH-2 not 29 sorry
