Newbie question

Sounds to me like it'll kill your catalytic convertor by running the engine on a rich mixture.

If you disconnect the vacuum supply to the regulator, it goes to full flow. So you could simply series the FSE with it and transfer the vacuum pipe.

It improved my old Rover 3500 EFI which tends to run weak at cruise, but I can't see how it will help a closed loop catalyst equipped car - the lambda sensor would simply try to correct anything it does.

Their website is very misleading. A standard regulator simply counteracts the 'suck' on the injectors as engine vacuum alters to keep the pressure at the injector tip constant.

Mixture control is achieved by altering the dwell of the injectors.

However, as I said, it might well improve performance on an early open loop injection system, but only at the expense of fuel consumption.

So it's not going to much on a 1.4 K series, which ISTR has the pretty good Rover MEMS.

Not much help if you've already bought the thing, but just in case you haven't; it's a waste of time and effort :)

Thanks for the reply that's the kind of info I was looking for. However I don't think I'll be getting one having read your next post and several others from various people.

I'm beginning to gather that. Thankfully I haven't bought one.

Have a look on Burgerman's website, spend the £100 on building a nitrous setup and get some serious go :). Then find another grand to pay your insurance ;).

I've paid a visit to the website and Nitrous appeals very much, but as you say there are the inflated insurance premiums after :-(
