This all makes sense in my head but I just want to ask before getting my hopes up. I know the ef's get their speed signal from the speedometer itself and not the speed sensor in the tranny like anything newer. Could I stick a newer sensor in an ef tranny and just do a little wiring and have it all work right? I'm sure with obd1 it would be fine, but what about obd0?

[HiProfile]

So you mean replace the cable unit in the tranny for an electronic VSS, then wire it right to the ecu?

The problem I see is how the cable-based cluster gets it's info. I would imagine the cable system converts mechanical motion to electrical signals, which is then fed internally to the gauge, then externally as the speed wire. If that's the case, you'd just tie the new VSS into that one wire, and it would make everything happy.

I've not tested it; however, this would make a great argument to switch to an obd1 cluster.

[PhilStubbs]

My reasoning for it is for a race car with no cluster, just a tach and a tunerview panel.


Damn, as I typed that I remembered the tunerview panel only works with obd1, so all should be well.

need a 96-00 VSS to clear the rear tranny bracket

Getting the old speedo drive out is the hard part.

[PhilStubbs]

I can mod the bracket, I have a plasma cutter and welders

Theres a couple of write ups on fitting obd1 vss in cable trans. The 88-91 civic crowd do this to get 94+ instument clusters to work

[crttaz]

fitting the OBD-1 VSS is not the problem, fitting it around the rear bracket is.

You can't get either for about $25, get the 96-00 and no need to weld, cut, or mod the bracket.

I have two SCCA Solo2 customers running the above setup. Took me about 30-40 minutes of grinding and fitting on a OBD-1 VSS to get it too clear.

what motor/tranny? 

I did a gsr cluster swap into my EF and had to do the E-VSS.  in my Z6 (A6 trasmission).  It was a bitch to get in but all I did was unbolt rear mount, get clearance, install E-VSS, then rebolt mount.  Wasnt exactly hard to do just a bitch to figure out.

[PhilStubbs]

I don't know yet. The car is in the planning stages. This was just a question that popped up while thinking about the build

[ironcrx]

Well with the crx si tranny (or most and D series Id guess) The E-VSS can actually fit with little to no modding.(from my experience!)

Since I just swapped a B18a1 into my ef, I wanted to keep the gsr cluster.  The speed sensor location is a good distance from the rear mount so Im able to reach down and pull it out no problem.

[PhilStubbs]

I ran an obd0 ls in my eg for a while. The stock sensor worked in there just fine. I don't really expect problems from the actual sensor, I was just concerned about the signal the ecu sees if it was the same from obd0-obd1.

[ironcrx]

ah.  with obd1 it was easy Well with obd1 I ran a leech wire from the signal wire (which goes from my sensor straight to the cluster) then used a leech wire from that to the conversion harness (speed signal)

however on obd0 it doesnt appear that easy lol.  ran it just like i did obd1 but cel stays on.  Its a small thing im messing with when I have time

[PhilStubbs]

I also realized after posting that the tunerview panel only works with obd1. This thread kind of becomes useless unless it helps someone else
