I thought I'd add a couple notes
pulses out of VSS for MK3 - this is a Can 99 car is 6000 for 1 mile.
Ohms for fuel gauge is 33 at full, around 250-260 empty.
For the W- rotor has 12 lobes and with pulley sizes works out to around 18 pulses for setting the VDO tach I have.
I have looked for stuff like this on this site and others and it's always hard to find.
One more thing - a 2252 turbo is to big for a 1.9 - I only have stock injectors as a qualifying statement. At full fueling I get 5 psi boost at most. I'm looking for a 2052 with a wastegate, to test next...
When I was still thinking of going wastegate the GT2056 was seeming like a good option. The compressor map fits the engine a little better than the 2052 variants, especially if you are planning on running higher than stock boost.
The 55 trim .53 ar looks better than the 2052. thanks
definitely looking for higher than stock boost - T25 flange is currently on the car so the 2056 is just a bolt on - outlet will need a bit of fabing.
