Been told if you want to live map your car to get a safe reading of afr you need to put a lambda sensor on the downpipe, is this true or can you use lambda in tailpipe?would the readings be any different??

Reading AFR from the tailpipe only really causes a problem a low speed because air may get into the exhaust and 'influence' the reading.
Also, any leaks in the exhaust will affect the reading too.
Theoretically, if the exhaust is 100% leak-free, then the difference between measuring from the tailpipe or downpipe is very marginal.
