Re: Share your MAF Calibration
CP-E claims that their CAI calibration matches stock intake, i s that even possible?

Re: Share your MAF Calibration
The cp-e intake I put on my gen2 was about 7% lean.
IMO having slightly oversize ID and skewing the MAF cal is how most intakes make more power on untuned cars. It increses actual load, leans the AFR, and increases timing. There is some flow increse over a stock air box, but that is not where most of the power gains come from. On a load based tune, with an exact match on the maf cal one intake should not make any more power than another. The ECU will not use the additional flow potential because it stops asking for load once it hits the load target.

Re: Share your MAF Calibration
note that the table is for the 3.25" MAF.

I installed the CPe Nano SRI from my speed 3 2008 on my Cx-7 2012 and the trim fuels values are good on ly +/- 2% offsetmrQQ wrote:CP-E claims that their CAI calibration matches stock intake, i s that even possible?

Re: Share your MAF Calibration
Anyone have a Maf Cal for me to start at for a Sure SRI with Inlet hose?
Re: Share your MAF Calibration
Do you happen to know what's the inner dimeter of the MAF housing for that intake?

Re: Share your MAF Calibration
Sure says its 2.5"
Re: Share your MAF Calibration
Then start from the stock MAF cal and see where you are. The stock MAF housing diameter is even larger than that IIRC (2.58"?).

Re: Share your MAF Calibration
OK so I went and measured and its 2.625".
