Default HFS-3 install Opel Astra OPC

I'll let the pics do the talking )))

The car itself (also sold as Vauxhall Astra VXR in UK).


The engine (2.0lt turbo, very similar to the one found decades ago on the Calibras and Vectra A)


Installation in process...


Tank behind the front bumper (right side)


Filling spout in the engine bay (behind the right headlamp)


Pump behind the front bumper (left side)


FAV in the engine bay (behind the left headlamp)


Pump relay in the engine bay (left side, closer to the firewall)


All wiring to ECU (injector, BCS) in the cable tray behind the rocker cover. All wires are behind the OEM plastic cover (taken off in the pic below).


HFS-3 controller in the cabin, below the glove box, covered with an OEM plastic cover from below (plastic cover taken off in the pic).


No good pic of the gauge unfortunately, will add later.

A couple of pics of the first fill-up (used some vodka for the start - it's Russia, you know).




Now, to the results. For me the reason for using WMI was an extremely aggressive map I had, too lean in the midrange and hence causing knock, ignition retard by ECU (as a protection mechanism, stable 9-12 degrees compared to base ignition angle) and eventually EGT over the roof (more than 1000C easily). With vodka (40% ethanol, 60% water) the knock didn't go completely and the peak ignition retard was not much lower, but the retards went rather sporadic, i.e. peak retards of 9-12 degrees are still in place but no prolonged retards under load. I suspect it may be also due to knock sensor hearing the noise from the exhaust or other tuned engine components - but will sure further play with the w/m concentration and HFS-3 setups.

The important part is that with retards now being only sporadic my EGT went normal which finally made it possible for me to put the car on a rolling road.
