Basically you need fuel, spark, compression and spark at the right time. Bosch or Regina system?

Hi,


Does it have an Air Mass Meter?

Regina was a cheap knockoff variant of the fuel injection.

starts and runs good now i replaced air temp sensor and IAC and fixed fuel guge wiped codes and no new owes cam up but i dont think that would have made it die at 55 mph.I think I still have something going on .

"Regina was a cheap knockoff variant of the fuel injection."

You neglected to mention that the Regina FI does the same job, to the same B230 specs, as the Bosch—with nothing to indicate any "cheapness" in either performance or operation.

I can't say why Volvo chose to use The Rex-Regina systems it for a few short years on the 700/900 NA cars. But I can say from experience, that in 8 years with a '93 940, I've found no reason complain in any way.

What's your Regina experience?
