What is the SPARK ADJUSTMENT feature which Indus Motor's installs in the factory fitted CNG kits of Cuore.
How is it different from the ordinary Landirenzo kit.
Any difference if cuore is converted to CNG aftermarket?
spark advancer and timing advancer are the same as far as i comprehend.If u can just add a TAP/timing advancer in the after market cuore, it would be good/compatible with the factory fitted one. How ever if u rarely drive on petrol, u dont need a TAP i suggest
Indus actualy installs retarder which works on petrol to retard timing coz petrol is less frequently used. do check it out from Toyota Dealer. easy installation but not easy money
for coure, i suppose, BTDC is 8~10 degrees on petrol and add 8 degees more to run on CNG. well, experience suggests 2 degrees tolerance falls in acceptable range. good tuners also advance spark timing for good initial acc. and help cold starting. let's say upto 2 degrees. but don't fiddle with spark timing unnecessarily.
