4.8 Truck norris cranking with no start

[edcmat-l1]

So I looked over the coil packs and they were definitely wired backwards...fixed that and the car fires right up. I can't put it in closed loop right now anyways since I haven't welded in my O2 bung and finished the exhaust yet. I appreciate the advice edcmat, you definitely put me in the right direction by saying to put the laptop down lol...now I can get the rest of the car finished up.

Good deal glad you got it figured out. Glad I could help.

That tune is in open loop and the VE is um, odd to say the least. I guarantee if you put it in closed loop it would have real issues trying to idle at stoich. I would imagine you have a meth system or some other form of fuel system (secondary pump that comes on via hobbs switch). But it doesn't even look right for that situation.

Yep. I have it in open loop for that reason, no o2 sensors just running on the ve. cruises at 14.7 and ranges from 11.5-11.8 in boost. No meth, just 93 with a single 450 pump. I do see what youre saying about the VE looking "odd." I assume youre referring to the duty cycles at a higher kPa. That is because I only have ran it up to 7 psi, so I have not yet tuned the VE in that range.

I'm referring to the overall shape of it. There shouldn't be dips unless you're pulling fuel because of some other source of fuel being introduced.

Cruising at stoich is one thing. Idling at stoich is another. I'd bet money it doesn't idle at stoich. And even if your WB says it's stoich, doesn't mean it actually is. You hook up some narrow bands and put ti in CL and it would not be able to toggle them correctly. I can tell by looking at the injector data.

You are right. It does idle a little bit rich. The dips on the table you are seeing im assuming are past the boost level that I run at currently, but how would you get it to idle a little leaner without affecting the AFR while cruising at nearly the same RPM and kPa.

TEAM OL4LYFE, amirite?

Proper injector data and closed loop operation.
