Is there a setting in the ECU where I can disable the speedometer? I'm losing it with these ECUs. One of them revs fine but has run-on, and the other doesn't rev past 1500 but shuts off immediately.

By the way, in case anyone is using the same wiring harness, and having the same issues, here's the link and explains the pinout issue and how to fix it...
Latest Update... After staying inside during Florida's hellish heat wave, I finally started working on the Jeep again. I couldn't figure it out so I took it to a local shop. After a couple weeks, the...
Quick update. I checked for vacuum leaks, and even adjusted the rocker arms, while it was running. I got rid of a slight knock, from piston 8, but it's still misfiring. I'm going to upgrade the spark...
I've been debating on redoing my dash to add a speedo that connects to the wiring harness, so I'll research it to make sure it'll fix it, before spending that much money. Thanks for all the help....
So here's the log with the Repo tune, a new PCV valve, the clean air port on the valve cover closed, and the same port capped on the CAI 132613.
I know I'm all over the place, and if I'm going too...
I was using the repo that you sent me. Should I try that tune after the changes to the CAI and replacing the PCV valve?
I have an extra PCV valve, so I'll change it out and see what happens. I went ahead and removed the tube from the intake, plugged the valve cover hole, and capped the hole on the intake. Here's the...
I'm going to take Sirius' advice and check all the mechanicals. One thing that got me thinking though, the passenger side valve cover has a breather port over the #8 cylinder, which is connected to...
I went ahead and emailed the tuner who wrote my ECM to see if he'll give me a way to access the tune. If he doesn't, I'm going to start from scratch, with Sirius's repo tune, take whatever...
Thanks bud. I checked HPT though, and it doesn't have an injector balance test option. I don't have another scanner either.
All the spark plugs look good and similar. The misfire plug looks normal. It's not oily, saturated, or black. I plugged the brake booster port on the plenum, but it didn't change anything. I...
I never heard that. Either way, I need to use the stock tune, because if I need to make any changes down the road, I'll need an unlocked ECM.
This is only my second engine build and my first EFI build, so I'm still learning everything about it. Other than looking for a vacuum leak in the intake, is there anything you can recommend? I'll...
I didn't need to remove it so they're still in from when I installed it. I switched over to the cann ECM and left the vacuum port uncapped. Here's the log 132348. I'm not sure how much I can trust it...
I didn't block it off. I just installed it a few weeks ago so I didn't even think about it. I'll do it later today and post results. I'm also going to try running the cann ecm with the vacuum port...
So I connected the fuel pressure gauge and it showed a steady 52psi while it was running. Before starting it, I tried finding the option to activate each injector individually, but I could only find...
Key On Engine Off. Never mind :doh:
I know I should probably know what this means, but what is KOEO and when you say pressure drop, you mean hook up my fuel pressure gauge to the rail, activate each injector one by one, using the...
One other thing I forgot to mention. When I ran it, using the repository tune, and before adjusting the fuel pressure to 19.1, the ECM wouldn't let the engine rev up past 1500 ish RPMs. It did the...
I did go in and replace the injector assembly, but re-installed the same gasket, because it was brand new and I didn't see the need to replace it again. I'll run it again and cover each vacuum port...
Took me minute, due to some VIN issues, but I was able to write the flow rate change. Here's another log after the change132278. It ran pretty rough and still had the misfire.
The part number for the Injectors is FJ504 and the link to them is https://www.summitracing.com/parts/smp-fj504

I'll fire it up this afternoon. I'm assuming there are channels for reading the individual injectors?
So I decided to just buy a couple credits and licenced the file. I understand what you were talking about now blindsquirrel. I installed the junkyard ECM and wrote the file to it. I fired it up and...
