Custom reluctor ring, suggestions on where to get one
Ugh, still working on this. I had actually decided to buy an MS3Pro box and dodge the "pay a tuner" bullet, but then I bought a '15 R/T 6M and have decided to go back to the Magnum ECU to save the cost of buying an $1100 box.
So, got my reluctor drawn up with 8 teeth and used the 4 degree notch size, ended up being like .27" wide. Little concerned it might be too small.
Worse yet, found this thread - Megasquirt Support Forum (MSEXTRA) • 426 Gen3 Hemi crate engine No Start (View topic) where the guy had problems with MegaSquirt getting a good crank reading using an '11 and up CKP sensor on an '08 6.1 crank. As it happens, I am using the same '11 sensor on my setup. I'm sure his issue relates to Kit's concerns at the beginning of this thread, but in my mind that doesn't explain why the guy couldn't get a stable reading until he swapped to a matching sensor. I could see him having issues with it if he was running the OEM setup, but MegaSquirt? Maybe it was a bad sensor to begin with and swapping to the earlier sensor more more about a good sensor rather than a different one?
In the end I think I am going to run it the way it is and keep the above sensor issue in the back of my mind. Just looking for any thoughts on the subject before spending money (again - already cut a 36-1 wheel).
