Can any one tell me how many steps the niehoff IAC part number 21774 motor has? At 300, and the block that was purchased from DIY auto, will not seal. I went to 320 and got a message that the setting had to be 300. Please advise.

That number can be changed in the activated megasquirt ini file, located in the megatune mtcfg folder. For example, if your using msII edit the file megasquirtII.ini and looks for iacstep, and change the Hi value to something over 300. As for the amount of steps for that part I cannot say for sure, my GM IAC motor seems happy with 300 ish.
