Warm Up Regulator Replacement Alternative
 

I installed a WUR alternative about 2 weeks ago and things are great so far. I thought I would share my results. Ihave posted this info to other forums so I apologize if you have already read this somewhere else.

I am in no way affiliated with this company.

The product offering supports 3 stages, each one costs a little more.

1. UTCIS-G Warm Up Cycle and Fixed Control Pressure
2. UTCIS-V Warm Up Cycle, Control Pressure Mapped to Manifold Pressure
3. UTCIS-PT Warm Up Cycle, Control Pressure Mapped to Manifold
Pressure over 1 Bar ( for turbos ), Control Pressure Mapped to RPM

Unless
you are having WUR problems or have modified your motor and need more
fuel I don't think it would be of much practical use.

Essentially it replaces the Bosch warm up regulator on CIS cars with
a programmable control pressure regulator. It mounts in the same
location as the WUR with the addition of a ECU that I mounted on the
left inner fender in front of the coil on my 928. I can program the control
pressures during warm up cycle ( from 0c to 40c ) and also the control
pressures after warm up with manifold pressure ( .4 to 1 bar ) via my
laptop. Right now I am using the factory control pressure specs from
the warm up regulator. But this product allows me to adjust for
better WOT ( probably need a wide band sensor to really mess with this
). If I lived in a place where the climate varied dramatically I
could adjust the warm cycle as needed. Monitoring the control
pressure and manifold pressure is as easy as plugging in the serial
cable into my laptop. This price is a little on the high side but
compared to a new WUR it is cheaper.
