Compression ratio and speeduino

Is Speeduino a better option for single cylinder turbocharged engines.

Also due to high compression ratios knocking is the main problem,how to calculate how much to reduce compression of an engine and can it be done by removing some material from piston crown.

Hello

i do not understand your question

what are you comparing it to ?

in many cases you can reduce compression ratio by several means

remove from the piston crown, renew the piston, add a thicker gasket or modify the chamber, there are online calculators to help with working out compression ratio
