Re: Another Successful Haibeck Upgrade
Paul - thanks for the honorary membership! I feel like I've just been admitted to the Knights of the Roundtable!
Dom - attached are the last two dyno runs. As you can see, there's a significant issue going on in the mid-range. When I got the car home, I, of course, immediately downloaded the program (😉  1470962824868.jpg and can see the problem. Should be an easy fix and will, hopefully, get it taken care of this weekend. For those of you asking for a video, please be patient. Can't seem to be able to send it thru this mobile app, so have to wait until I get back in front of a computer.

Re: Another Successful Haibeck Upgrade
So your RW torque is a little on the low side....looks like mine. I did not get mine tuned but got 441rwhp@7100 and 373ftlbs with siamesed runners. Would be interested in the result with 36mm ports

Re: Another Successful Haibeck Upgrade
The mid-range torque dip appears to be a fueling issue. Marc tells me our secondary fuel pumps kick in around 4500 rpm which causes the AFR to go rich until the fuel pressure regulator catches up. Need to take some fuel out in the mid-range to compensate which should bring the torque numbers up.

Re: Another Successful Haibeck Upgrade
Dennis,
Can u display the AFR curve? Also that torque "dip" is not atypical. Appears that it's a characteristic of the LT-5. Maybe Graham could chime in Last edited by XfireZ51; 08-12-2016 at 12:32 AM. |
