Hi guys

I just got meth installed for my N55 XI yesterday. The kit i bought was from BMS to run with their JB4. The shop told me to use auto map ( map 5 ) . They also did the mixing 50/50 meth and distil water for me.

Today, After a 3 hours country trip with hard pull and average speed of 70, when i check the 2 gallon tank in the trunk, it still full with the mixture, just like it never been used.

1. Should i use the map 3 for meth , or map 5 is fine ?
2. With no drop in mixture level in the tank, does that mean meth system not working properly ?

I did search the forum but did not find any topic relate to meth with map 3 or map 5. Please help me

Thank you

Meth works on map 3, 6 &7. It does not spray in map 5. Your best bet would be mAp3. It is an auto tuning map like map5. Start with a 55adder and log and go higher if everything looks ok.
