Art, 4 cylinders probably sound a lot rougher than an 8. 12.8 is where I run mine. If your ECM is fast enough that should get it. You tap the L key on mine to make it learn. Takes more than once. If you can set the Gain for the learn function kinda low it won't be as likely to over shoot the target. Mine tends to do that, go too far first time. I just log it and make a change, then run & log it again. I can usually hit second time if not the first.
