67 dart stroker hellcat gen3 hemi with twin turbos...

interesting. heads ground strait to battery. checked tonight(pic included) i installed them and ground goes back to battery. they are also tight not loose on connectors etc..
im running factory 6.1 coils but do have old plug wires. which im leaning hard on replacing asap with better wires.
running ngk6010 plugs. not sure if resistor or not right now.
it doesnt have a miss fire. it literally loses cam sink at random. it might do it at idle. it might do it at wot on a pull or maybe just trying clean rev the engine. never a crank sensor error in the system logs.
im hoping v6 update software does the trick but ive yet to install it. plan to this weekend.

now besides that issue. non of my i/os work either. my boost controller did for about half a pass and died as well. never to work again.
no cheap sensors except on my water pressure sensor. it worked for maybe 10 seconds and **** the bed to.
ive replaced the driveshaft sensor twice. no luck. has power, signal and ground...no operation. checked gap and adjusted to closed to wide open..nada.
cant go fast or make a full 660ft pass till dss and cam sync issues are resolved. sucks having a car i know will run well into the 5s on 5psi but cant make it to the stripe without problems.
never mind my bump box doesnt work.
so ******* frustrating. its warm enough to test but when ***** fucked. nothing but defeating to say the least.

We are having similar problems. My bump wasn’t working (Holley V5) either. It works now but it’s not perfect. I have to spend more time on the brake to get the settings dialed. Those plugs are non-resistor. Its amazing how sensitive the EFI is on grounds. David Reher of Reher-Morrison did an excellent article on grounding ignitions. He stated that on aluminum heads you need to ground both ends and that chassis grounds are not good enough. This was from the early 90’s before widespread efi.
