Hello from Germany,
I experienced some engine issues (http://www.gt40s.com/forum/gt40-tech-engines-induction-exhaust/43096-roush-353ir-accel-dfi-ecm-file-needed.html#post441397) and finally (after searching the forum) checked the throttle adjustment via air flow meter and did not like what I found.
After playing with the adjustment I saw changes (good and bad) and finally had some huge improvements.
On the Roush website I found an "Installation Manual" which helped a lot during adjustment: http://www.roushperformance.com/engines/manuals/R21180001-10-AA-8-STACK-EFI-Instructions.pdf
However I still have issue when trying to tighten the turnbuckle style linkage rods like described in the Roush manual:
“With the linkage rods at an adequate length, snug both lock screws at the ends of the left bank rod in a position that does not put the ball ends into a bind. The locked rod should be able to twist back and forth about 1/6” of a turn or more.”
My problem is:
I get the airflow right or the alignment of the ball ends.
I’m not able to get both right at the same time. Currently I’m fabricating a “ball end alignment tool” so they don’t bind during tightening the lock nuts on both ends. The tool works like a fork to keep the two ball ends aligned (one horizontally, the other vertically).
How do you make the adjustment on your ITB or particular how do you retighten the linkage rods without forcing the ball ends into a bind and keep them horizontally and vertically aligned?
Thank you in advance.
Markus
P.S. I don’t tell you what parts I have already changed before looking into the basic things……
… but like usual, when finding the right thread you find a solution, it’s all there
