I'm not sure why they don't promote them more, but here is the page with the 85mm & 95mm Tuner MAF's http://www.cnlperformance.com/tunerMAF.html I found out about the tuner tube while using Clint's EEC Analyzer - he had curves for the "Tuner Tube" and I then called C&L and got one as my meter was maxing out with the straight-through tube I was using. I was immediately impressed with the cleaner voltage signal and the lack of adjustment needed to get the car running with consistent near 1 KAMRF's. Yesterday I was lugging at 30MPH in 5th gear (1000RPM) and was quite impressed with the smoothness - pretty impressive with XE270HR cam I'm using. |

I do remember seeing one of those meters. My 70mm meter has a straight tube - I got it from a Supercoupe though - I guess I forgot about that difference. The electronics are the same however.

I think i need to dump my 76mm C&L too and get w/ the PMAS80mm! Mark wasn't pleased that i had the 76mm when he did my tune, but for a couple of weeks all was well, smooth ride at 17-1800rpm in 5th (4 me that's low), or sometimes she'd get great gas mileage, others omfg sheesh this thing chugging too much gas down wtf?!
But ya grab myself one and get a re-tune all should be well after that! |

Update C&L testing
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.

Hi all,
Well I don't know what could be going on, but I've tuned my 76mm C&L with three setups on my 90GT 306. 1. NA with MAC cold air kit. 2. NA with stock air box and K&N. 3. SC 8psi KB Blowzilla with stock air box and K&N. All tuned very easily with an LM-1 WBO2 with rock steady idle and very smooth throttle response. Guess I'm just lucky. Don |
