Thread: Mapping a de mafto n60?

I do not have the bin saved on my computer, but it was over the calculations I had made:

(old injector size/new injector size) x old_K = new_K

(370/333)(28646)=31828

I remember i had to bump it up a little bit to get the idle to be around 14.7.

Recent driving has shown that sometimes the car will idle down below 1000rpm, and the afr's will richen up to 10 or so which bugs me. Full throttle is around 12.8, so that will need to be tweaked as well.

I will have a chance to look at voltages this weekend, crazy week at school.

And for anyone else this most deffinently has given me a noticeable power gain up top. And I have used the SAME bin before it was modified for the maf. This is Calums stock cam bin, which I suppose is designed to be safe in the timing dept. The tires spin in 1st when vvl hits on dry pavement, which rarely happened to me before. Also the top end of 2ms and 3rd feels really good!

I was also meaning to ask you: When tuning, all the bins i have if I floor it under 4k, the afr richens to 10's and slowly comes up towards target afr. Is this extra fuel needed? Or should I tune it out so it is 13ish all the way down under wot? Make sense?

Thanks!
