76MM C&L volts goe up when RPM goes down
Hi Tuners, I have been chasing a problem and I think I have discovered a significant clue. Normal idle is 800 RPM, about 22 KG/HR, .7 volts.
When the fan comes on, the engine usualy dies. I data logged this and saw that the MAF voltage went up as the RPMs went down. see below RPM 800 700 600 500 400 300 MAFV .7 .71 .72 .78 .8 .85 Maybe it's time to give up on this C&L meter and go back to stack or a Pro Air meter. Input? Thanks, Eric
