Got everything pretty much buttoned up. With the swap the tach still didn’t work and the rvr gauge clusters that were on the forums/Facebook groups have been sold. I read up on some things and used Jason’s write up on the tach filter for the csm. Had a spare gauge cluster torn apart and found the tach signal pin.
Here is the tach input(Phillips head circled in red) which goes to the dash harness fourth pin on the top(red arrow pointing to it)
I pulled the coil pack and had to pull the fuel rail to actually be able to pull the coils out. Installed the 90 tach filter and wired it in. There’s two “in” wires that I connected one to each coil on the top. The “out” wire went inside to the underdash connector.
Favtory 2g 98 coil pack on left and 90 csm on right
I used the same 98 bracket and there was a threaded hole so I mounted the tach filter there and was out of the way of the rear of the components.
The out wire(white) from the tach filter was ran under the dash and connected to this connector here. It’s a black connector on one end and white on the other.
On lilevos’s site he goes to a big black connector under dash but it’s not the same as the van. Instead of cutting the wire and soldering into it I pulled the pin and taped it up as I had a spare pin I could use(just keeping the factory one uncut for future reference if I ever need it)
Since I had the fuel rail pulled I also had some pte 1000’s from the engine with spun bearings. Pulled them off the old engine and put new o rings on.
Used DSMLinks site and set the injectors up with their data.
Got the van fired up and the tach works!!!!
Got a quick log and I’m seeing positive boost at 1600rpm and spiking 11psi at 5600rpm and dropping to 8psi(no boost controller hooked up, vacuum line straight from turbo to wastegate). Intake air temp got up to 202* so next on the list is a FMiC( I have an evo 3 IC and most of the piping I’ll have to mock up)
I’ll be putting some miles on it as my DD and the next update will hopefully be a fmic install and e85 along with a little more boost out of the 11b.
