need help. Finally got the car to run better today but all she wants to do run rich.. and you will see that in the readings... I keep trying to a just dead time and the maf but just cant seem to get it right. Im about to go back to my stock injector and see if that helps but if I can get some guidance on here I want to keep the 650's in there... I also went to a 2g maf and dsmlink all at once. so here are some of the reading hope this helps just tell me what else you need and I will get it thanks in advance. it also bogs down with any throttle and at times will stall when coming back down to an idle.

Ok so I post this in the wrong area and get three people telling me I posted in the wrong area.. I'm asking what I have or did wrong with my tune and nothing. Not even hey start here. How do I get help post this agian in the wrong area at lease I got some answer. Thanks
 
looks like your idle control valve doesn't work as it shows 0 and changes in different logs from 8+. It should be at 30. Also you may have to much deadtime according to ecmtuning site 650s have around 200 or so.

Now I'm unfamiliar with v2 so I'm sure what you can do or not. However, you should run a tps adjustment if you can.
 
Thanks man I don't think I can change the tps with v2 if I'm wrong someone will let me know I hope. Some of the logs I may have turned on the tps setting to simulate the reading. But thanks for the help I thought I had the dead time but I will try that. Thanks agian just needed a fresh set of eyes.
 
Wally 255 with a fuel lab fpr and I do have a wideband waiting on the harness to wire it in. The WB right now is at full rich 10.0. I appreciate the advice. But I'm stuck with v2 for now til I can get it running better so I can get it home. That's all I really need then I can fine tune it and get v3.
 
Play with your Global. Write down what it is now and vary it up or down considerably and just see what happens, you can always change it back. I had to play with mine when I switched over to E85 this weekend and I did it while it was running and driving. Just know where you started so you can change it back. Did you use the injector calculated values? Sometimes they are close and sometimes you will have to play with it a bit or I did. Just giving you some idea's is all.
 
Good question Tony, I don't know what can be tracked with V2.

The tps is there I think but it shows no value. I did use the calculator and have been playing with it. Where I have it seems the best idle. It I move it off 210 and go up it starts running like shit but I will keep trying. And to the other values I thought I got them all but I will try agian thanks
