Anyone know anything about Stand alone Engine Management? Are they reliable/durable? Do they screw up the engine? Do they suck up a lot of gas? Thanks.
I've got about 3-4k miles on my Hydra with no issues. In my opinion there can be quite a bit of tuning involved but if done correctly there really is no real worry about harming the engine. It depends on the exact one but allot of them even have features to cut off the ignition in an over boost scenario or under excessive knock. Again it's all your work to set this up properly and if you paying someone that can get pricy but again done correctly I don't see an issue.Anyone know anything about Stand alone Engine Management?

on the high-end (EFI, Pectel, Motec, etc...) they all work similarly. From my experience using these systems one manufacture might have a feature over the next one and vice versa.any standalone works as long as it can control VVTi.. motec is probably the most comprehensive, for track use..
I am confused...No standalone I'm aware of will legally pass anywhere in the USA (unless its on a car thats exempt from emissions/clean air act/obdii ) Most of them don't have the software to run the OBDII or properly pass the emissions standards (not the 'sniffer' test)
Its a federal law, not a state one.
Of course just as in CA you can fanagle your way around it , but its not legal.
My '83 VW GTI uses standalone (megasquirt) and passes emissions. Ironically it also has a 1.8 liter supercharged engine however it puts down a bit more power than my '09 Elise SC.So would they them be legal on cars that do not use OBD-II...
