Yes , the Volvo setup is a first generation vialle .
The pump is the achilles heel . Won't last for 25.000 km .
The next generation pumps is a little better .
The pumps , I think , are rpm controlled by the ecu .
They are constructed like a 3-phase asynchronous cage
motor , and require substantial electronics to get them going .
I'll try to make some pictures next sturday of the components .
Or check the yahoo group foto section .
Folder called PAT , there where pictures once .
I'm dutch speaking , and I've send a lot of emails
to the vialle company in Holland . Never got a single reply .
Guess they don't like diy people .
The injectors are put on the IM by vialle itself .
Injector pockets cannot be obtained , you have to ship the manifold
to them . The injector itself spray's on the side .
At a 90° angle so to speak.
Don't know where they aim them , but I've heard of problems
with ice blockages inside the runners . Guess they have to be dead on the intake valve . Best bet imho is to get rid of the petrol injector and put the lpi injector in its place .
The engine was an I5 ( not an audi ) non turbocharged .
The lpi engine management , wich I also have from the volvo is an 68HC08 based . I can even extract the hex dump out of he eprom in case you'd like to dissasssemble it .
The management reads the petrol injector pulses , and recalculates them
for the lpi injector .
Altough vialle states they have sequential injection , I can proof
that their setup is a batch system , just like ms .
Each injector has its own driver , lm1949 based . But all the drivers
are tied together to a single . No way to do sequential with that .
I can obtain these injectors , and maybe a tank with pump from a friendly dealer I know . If I'm not mistaking , one injector is abt 150 euro .
Tank with pump close to 700 euro .
I'll make sure to post some pictures , and explain how I think some of the stuff functions .
