Hello,

I'm now on the 98ron map, i have 2 fuel maps, and i drove the tank all empty on Ethanol and filled with 98ron (here in Belgium). So right now the car doesn't start on normal 98 fuel with these Denso IK31... my ignition setup is:

EMU aftermarket ECU with coil on plug (i think from yamaha bike). So normal plugs like 071 don't work i guess?

What about if i go IK27?

Cheers for the help so far!!
