Rover gauge questions

[l6rth]

I have just been checking out my 98 450 using rover gauge and it has a fault code 21 map/fuel resistor out of range and is running map 0, I don't think this is correct but it may have been mapped before I brought it. On further investigation I can't find a resistor like I had on my 400 original or modified I did find a plastic plug with a few black wires all leading back into the loom which I don't recognise, I don't think its related but I also have a faulty lambada sensor. It does smell fuely and has pre cats in and and act y.

Just seen on another thread that map 0 is limp home mode which can't be good. Would this be caused by a faulty lambda? Also I saw that map 2 is uk non cat map, how do I get it to run this map?

Thanks

Done some more digging, found the connector where the resistor should be but wasn't luckily I had a resistor from a previous car so I am now running map 2 fully de catted, would limp home reduce power? Also change lambda's however since doing that rover gauge isn't showing the lambda' graphic at all. Can you help with that blitz?

Hi mark, the resistor now connected is the one you told me to buy from ebay a few months ago, don't remember the rating. I'll check my emails from you mark.is running map 2 a problem?

Can't find your emails mark, can you pm me your email address so I can search for them. Thanks
