Will a ecm from a 99 automatic work in my 99 manual?
I know a mad ecm for an 01 auto will work just fine in an 01 HO.
The 99 auto ecm wont have the idle up to prevent stalling that the manual has. I can send you an 99/manual/federal recovery to flash with your smarty.
when doing the auto to manual swap in a 99 do you have to change the ecm or jsut run it with the auto ecm is it necessary thanks alot for the help.
Did it fix your problems?
it will work just less horse power and you can take it to a cummins southern plains if you have one near and they will flash it to work for the standard.. my 99 use to be 5 speed and switch to auto and still run the standard ECM..
