Hi Stangers,

I got tired, of messing with the 76MM C&L and decided to go back to the stock MAF. My plan was to get the car running real good and then try the C&L.

I was able to get the stock MAF running fine. Without changing any mechanical adjustments, I put the C&L back in, tweeced the new MAF curve, and gave it another shot. The tune was really close but I could tell the idle was not as good. The KMRFs were perfect though.

With the stock MAF, I was able to disconnect ICS, and the engine would drop to about 700 RPM. Trying the same trick, with the C&L, stalled the engine right away.

If you recall, my problem was that the engine would stall almost every time the low speed fan would come on. After I went to the cobra tune, with my stock MAF, those problems went away.

So, what do I think I have learned? Well, for one, the idle MAF was the same for both the C&L and the stock MAF. That tells me the MAF calibrations were good. By the way, I used Clints 76MM black tube 24# 70MM sensor curve from the EECA.

I think the C&L has problems at the low MAF flows, because the larger flow area, and the way the tube only looks ,at flow in one spot. the stock MAF sorta averages it because of the divider that goes across the MAF.

Where to go from here? The stock MAF is getting to about 4.8 Volts WOT. I suppose I could live with it. I probably will given that spending $200 would only get me about 10 HP. I probaly will put a K&N fliter in and call it good.
