Can you map a n/a car without map/maf?

Just reading my emerald and it says in map sensor settings that its not in use. its a race car by the way so dont use Iscv either?

 

yeah course, just speed vs throttle angle otherwise known as Alpha-N

 

when you say speed you mean RPM?

 

yes is the answer, tps is used instead verses rpm, tends to be used for bodies as ITB's pulse and require a chamber to smooth it out.
perfectly fine, more sensors mean more scope to get more power/smoothness, but also more work for little gains in some cases.
