bucking in drive and OD

Posted

I have been trying to get the bucking out of my truck. It is driving me crazy and i just found out how to do a datalog. It seems to be getting worse over time, and I'm at a loss for what to do. Can someone look at this datalog and tell me 1) what is going on and 2) how to try and remedy it. Thanks for any help.

    I like ot set Timing reduction to 5* then timing reduction scaling to %50.  That way you get a very fast pull in timing when you try to pull in a lugged state.

I'm wondering if it could be an injector issue

This past weekend, I put the stock ones back in and it did it bad, then I have a set of DDP 125's and I put them in and it still did it. It only throws the one code, so I just ordered a reman ECM. All I can say is we'll see.

First and foremost let me say this site is awesome and second I'm a dumbass. So in my signature you'll see I put this motor in my F250 and had to build a wiring harness so I contacted the guy that I bought the engine from because it was supposed to come with the harness and he sent me one. Evidently it wasn't an O2 harness or a 01 so it had a crankshaft position sensor plug which is exactly like the Cam sensor plug so when I looked up the wiring to do my harness I reference what wires were in there instead of going to the 2002 wiring harness for the engine at this site. Well after ordering a computer and putting it in and still not working I decided to rip my harness completely out and print out the schematics so I could go through it. Well what do you know I found the issue I didn't have the cam position sensor hooked up so this whole time since I've been driving the truck it has never worked. Well I redone my harness, reinstalled it, and put my old computer back in.  Works perfect so now I'm stuck with a new computer or I can just send it back and lose 50%. Either way it was sort of an expensive lesson. So I guess my question is now with the cam sensor never hooked up and the ECM never reading it then how did my tack on the Quadzilla work?  Was everything based off of the vp44's own timing? Now I hope this is the last bug I've got to chase down. I've only got two other things to do and that's to hook up my AC and do the cruise control. Thanks for all the replies and all the help I really do appreciate it and my knowledge is vastly growing on this motor.

    Man what a relief that must be.... Maybe you can put your new ECM in classifieds here, seems a lot of people lately had issues with them.
