Last year I installed the Fast Forward Automotive? Hasenwerk VSS Korrekt Speed Signal Calibrator that can convert the frequency of one pulse train to another:
http://fastforward.ca/signalprocessors/ (about 2/3 of the way down the page). I installed it, and went for a series of short drives, each time adjusting the converter so that the speedo reading coinsicded with the GPS reading and the OBDII reading. It took
two or three tries. That fixed the overspeed cutout problem with the Subaru EMU.

Re: Evoscan . speed sensor signal . & other signals
Funny thing is that I have been running this for a decade and never noticed a cutout at speed . maybe it’s a OBD II thing . I use OBD I for California reasons …

Evoscan . speed sensor signal . & other signals
Hi .?
?I am doing my best with evoscan without support .?
?quick question .?
?I know there are many ways to get a speed signal back to the ECU . Mine is a sensor off the back of the speedometer . i drove while logging data with the EVOscan yesterday and to my surprise I am reading a much higher speed than indicated on the speedometer of GPS . . I have used this setup for 100k miles on the previous longblock so i cant imagine it's that big of an issue but has anyone seen the need to adjust the speed feed ...?

"No-Donor" Harness Launch
Greetings,
?
Since taking over SCP 2 years ago we have been slowly revamping, creating, and building new solutions for our beloved Vanagons.? I want to thank everyone who has responded for beta testing the next generation of interface board.? The boards
should be here in the coming weeks for QA and we will reach out to people interested!? ???
?
In the meantime, we have been working hard to stand up production for “no-donor” harnesses.? We are live and scalable.? Imagine a world where the harness is on the shelf ready to go or the lead time is a few days?? There is no need to hack
together old shoddy wires that have been through thousands of heating and cooling cycles.? And for those of you in 49 states (sorry CA)—this should be a welcomed addition to arsenal of products to create your next generation of Vanagon using drive by wire
motors with higher HP and better reliability profiles.?
?
We will be evaluating more model/year combinations and there will be some opportunities to create harnesses to satisfy more people’s needs.?
?

Re: Anyone want a free chipped EG33 ECU and/or MAF sensor?
I will send the ECU to you when/if I find it. Do I have your address yet??
Jeff: Derek sent me an email saying he only eeds the MAF. I'll take the ecu ifit is still available. Please email me at:??whocanduncan1@...
Thx!

Richard, I've been trying to understand your suggestion to disconnect battery ground then connect positve to that ground. Won't this still create a short and wreak havoc on the capacitors? Maybe I'm not understanding which positive and ground wires are involved?

Re: Anyone want a free chipped EG33 ECU and/or MAF sensor?
It will most likely be a D1, although the tune chip would be an aftermarket addon. All OBD1 versions ('91 to '94) are interchangable, I think. Someone please correct me if I'm wrong, as I have limited investigative knowledge and would like to know more.

Re: Anyone want a free chipped EG33 ECU and/or MAF sensor?
Not sure about version. I believe it came out of a '92. It has an EcuTune chip.?
3.0...that's what I should have done 1,000s of dollars ago. keep in mind if Derek changes his mind on the ecu. btw, what version is it?

John, If your speed sensor is set too far away you will get this problem. Same thing with Hall effect sensors. Put your sensor closer and you'll get better pick up. Good luck Terry
Subject says it all. Have 2.5 installed with Precis ECU the harness conversion done by Busaru. Stock '91 auto tranny and stock 14 inch wheels. At 65 mph and above the engine starts bucking. The only way to stop it is to reduce speed below 65 mph. On a few occasions I have managed?to hit 70 before bucking sets in. At 70 mph the tach reads 4000 rpm. Has anyone got any ideas about the problem and how to fix it? I should be able to turn 6500 rpm easily with this engine but I have no particular need to do faster than 70 in most cases. The VSS is Busaru and is set 4 mm clearance from stub axle flange?bolts.?
All comments and and suggestions would be appreciated,

Re: Engine rapidly off/on/off/on/off/on at speed
I am not sure if this is relevant or not....but I have an old Audiovox CCS-100 Cruise Control on my Vanagon with EJ22.? It works Fantastic!? It uses magnets on axles to determine speed.? Well...I replaced those magnets with modern ones....you know, the rare earth metal kind.? Before, if I would hit a bump in the road, the Cruise Control would lose it's mind and shut down.? Now, with powerful rare earth magnets, everything goes just fine, bumps in road or not.? It made a huge difference.
