1st DT Malfunction

[KMORGSM5]

Did a few pulls over the weekend, car was running well given the heat outside. I did get my first DTM Error at the top of 4th. See list of codes in attachments. I quickly got off the exit, turned car to Map 1, turned it off, locked for a couple of min, came back, started and drove off. No codes and was running fine again.

I don't see anything attached. What map were you running. Do you have the BCM?

Do you not see the PDF?

Yes i am running BCM, I was running map 2 on 93 pump. Terry at BMS Said my fuel pressure dropped in the log. Waiting on what he comes back with since i did say that i was at about 1/3 of a tank.

do you have comp package? If not you may have maxed out your short term fuel trims, also i would run a little more octane at 22psi with a jb only and no meth

I just looked at your codes, it misfired all over the place, I would definitely say its fuel related. A spark plug or coil issue wouldn't happen on so many cylinders at once

join the darkside, go flash with me buddy

I see on Mobil app my pic doesn't show up. I've done it on my app, should show up now.

Yes, it's competition package and have run it on Map 2 most of the time no issue, could have been doing the run on less than 1/3 a tank of gas. Fuel trims looked ok until fuel pressure randomly dropped then came back up.

I know a few have had problems with a tune (flash or JB4/Piggy) where when the fuel tank level drops low (~1/3) and had missfires and DTM's etc. Not sure if its a LPFP problem or just starvation.

[MCarsFan]

Your best bet is to load a tune and join the dark side.. No dtmal for me.

[KMORGSM5]

Might go that rout in the up coming months. So far I have been happy with my set up, plenty of power. In fact I love the fact that adding a tune would make the power more usable.

[ur20v]

No DTMAL's for me either with JB4+BCM at 23psi. Not sure what that proves or what the point is.

I am guessing there is an underlying fault (LPFP or pick up etc) causing the problem, CP's are normally perfect as they run richer and have a higher cieling for fueling where non-CP's can be marginal on Map2/23psi.

Other than the muffler being different, can't a non-CP car just be flashed into a CP car, then when adding a tune and/or JB4 you're at least starting off with a better base?
