Ita 33.3% but it works well

You are putting too little

Yes but as mentioned in another thread, if you keep doing that you may end up increasing the ethanol content unintentionally.

The first time you do it, you might be running 30%.

If you fill up with 15 litres left (which will include ~4.5L e85), then you will end up with 24.5L e85 in a full tank. 24.5/60 L = 40%

Fill up again at 15L left, and you'll have 6L e85 effectively (15 * 40%)... so 26/60 L = 43%

If you repeat enough times, you're going to end up with more ethanol than you wanted and the fuel system won't be able to flow enough ethanol. Your system will lean out.

Even just running map 1 would it be recommended to do plugs, coils, CP, DV first?

Nah. For map 1, just change coils and spark plugs if you're not sure when they were last replaced.

Unless your charge pipe is already damaged, map 1 is unlikely to cause any problems with it. Dame with DV's.

Download the e85 calculator on your smart phone. Phones are pretty smart to be able to calculate this
