Hey guys, had anyone installed the big 3" cold air intake on their 86, which requires a tune( rescaling the MAF) to be precise. I'm not familiar with tuning and whatnot and have been getting great help from the forum members on how to rescale this. I ordered the OFT From Vishnu and am awaiting that now. As soon as I receive it, I will install my 3" CAI, then Plug my OFT and read it to my ECU, then use my laptop to adjust the scaling given by Perrin. Then Write it using the proper stage of course, which in my case would be EL header stage 2. Does this seem about right or am I missing something? Should I read my ECU Before or after I install my 3" CAI?
