Title: Marelli Contactless ignition : changing the coil ? Post by: Modano on June 04, 2022, 11:15:58 AM Hi
I have the contactless marelli on my Coupé (Pickup sensor, ignition module, SM806AX distributor ) My coil is a Marelli AEI200A and resistance measures are OK. It doesn't seem that there is any specific ignition weakness, but I have a brand new coil (Elprom B1174) I got a couple of years ago. Is there any case when, (assuming HT cables, Distributor cap and spark plugs are ok), a coil with proper resistance measures is not deliviring its maximum output , and swapping to a new one would enhance the spark power ? Same might go for the ignition module below the heatsink. On the other hand, I know the cable below the distributor rotor may wear, but I would experience misfires. Here this is not the case, so it's rather a potential free optimization. Of course, assuming my Elprom coil is for contactless ignition but I cannot find anything on this reference. Not even sure the manufacturer is still alive. |
