10V Turbo swap question

[Ben Swann]

Dan,

 

The computer functions are totally auxiliary to the engine operation.  You
would need to install these as an entirely separate subset of wiring, etc.
or not at all.

 

Fuel pump cutout related to boost pressure is handled within the ECU. - a
wire (pin 21 - See pinout)  controls the fuel pump relay.

 

I may be mistaken, but you may need to install and rework the engine in the
vanagon syncro so it runs backwards( cam, crank seals) - I'm not sure.  You
might want to do some searches on this.  It may be the transmission handles
this.

 

Anyway, other than that, the engine management system can be made to run
standalone as long as you have the Idle stabilizer control unit as well as
the ECU, proper fuel pump relay setup,  and of course 12V positive and
ground connections.

 

I laid out some of this wiring detail - see:

When someone does a 10v turbo swap, and they save and rework the ECU and
wiring harness.

 

do they retain the trip computer and the boost/milage display part?

 

does it work without those components? how is the Boost pressure fuel pump
cutoff 'feature' dealt with? 

 

I'm not doing a 10V T swap just yet, and mine will be slightly unorthadox ..


not going into a 4000Q but into my 1987 Vanagon Syncro camper. 

 

I'll be driving and enjoying the 5000 CS Turbo while I accumulate the parts
necessary and restore the body and interior of the syncro
