Just to be a nitpicker here - things can't intermittently fail. Failure is permanent, so if your issue is intermittent. it is not a failure. Ignition Coils playing up will causes misfires but shouldn't the transmission make a bang sound. Did that sound a bit like the engine revving up and then it going clunk as it changed gears? If the coils have been replaced, possible that they were replaced with fake parts? These are rife on ebay on online stores. Also if you have a suspected failed coil easiest way to test is to swap it to a different cylinder and you should see the problem follow the suspect coil. If the problem doesn't move with the part then your problem is suspect.

I am again wondering whether configuring what the PCM outputs on 0x623, 0x640 & 0x650 CAN ids is enough to 'trick" a TCM or ABS module into functioning with a different strategy/config. But I have not a lot of experience with the automatics.

"LandBarra". That is genius.

at this stage unsure, its something that may be better tested with modules on a bench and a simulator rather than in a vehicle.

is this a 5.4 or 5.0?

There is a diagnostic routine that can disable the safety software - it may be possible to actually do this with minimal effort, just need to test it in practice. Test it in the red herring mobile.

Has anyone fiddled with this flag? I set to 0 today, yet to log any data and see what it does.

Mate I have a 5.4, it is a 300k track car. Almost.

It is just saying if the sensor output seems unlikely to be true the PCMs failure strategy is to ignore the sensor and replace that value with that of the cylinder head temp sensor value - keeping the engine runnning pretty much as it was before the failure - so trying to fuzz this signal to the pcm wont work - as it will just ignore it. You probably want to cause a condition where the pcm sees 140-160 degrees celcius at the CHT - as it will start shutting down cylinders and dumping fuel in to try cool it down. Roland has mentioned it in these forums before i'm sure, all the parameters are in the software, you can set the failsafe point temps as they rise and fall.

Bosch ABS Boot Mode (nefariousmotorsports.com). Its on my list.

@WhitefordIf this is just the rear tyres - you could wire up a switch that causes an open circuit in both Rear Wheel Speed Sensors -> ABS module wiring -> CAN Data now broadcast from the ABS for the rear wheels becomes 0xFF(invalid) and an ABS fault is triggered, you lose ABS, TCS and DSC and the cluster doesnt shut up, but you are not in LIMP mode and can race car all day, hit the switch and back to normal. Yes / No ? Take it a step further and open up the ABS module, get into the firmware and write some software that can edit all the thousands of parameters that are probably in there. Then you can "tune" the antilock braking system.

Edit: Could be this. As those DTC from your scan tool reference the following: 1381 P1381 Camshaft Position Timing Over Advanced (Bank 1) 1383 P1383 Camshaft Position Timing Over Retarded (Bank 1) But they do not error for the following: 1380 P1380 Camshaft Position Actuator Circuit (Bank 1) 1382 P1382 Camshaft Position Timing Solenoid #1 Circuit 1384 P1384 Variable Valve Timing Solenoid A Circuit

Wiring. 4.5V before issue and 12V after issue happens (operating temp) Is a this a signal wire into the PCM from the Cam Angle Sensors? if so I don't think a signal wire is meant to be 12V for an ecu. I would check every wire on the PCM plug for shorts to a 12v power source. What gets 12V at operating temp? Cooling fans do, might be something to check.

May be of use to note that the data provided by manufacturers for their injectors is obtained using calibration fluid - which is of a different viscosity to fuel, so the data from the manufacturers may not be necesssarily the best data to use as it was obtained with a fluid with much different properties than fuel.

I don't mind snapping a few bolts here and there. Is anyone willing to donate a SOHC 5.4 Crate motor from the states? I think theyre about $30,000 and come with 800 horsepower ready made.

I am thinking that the 5.4 PCM is not going to work at all with the Terry ABS module. If it was a 5.4 PCM and ABS, no dramas. Edit: The 5.4 220 KW engine OP is talking about is different to the later 5.4s I was talking about - OP's engine is a 3V 5.4, not an XR8 or GT Boss 5.4 4V engine so that may need to be taken in to consideration as well

Nah, 5.4 V8 PCMs are only going to work with......5.4 Litre V8s

Nah, 5.4 V8 PCMs are only going to work with......5.4 Litre V8s

Hey this is a bit of misinformation - The ICC will work fine regardless of PCM or PATS - when a PCM is changed out and the AUDIO CODE ERROR comes up on the ICC its cos the battery was likely disconnected during the PCM swap, you just have to do level 1 security access 0x27 on the ACM and it will clear it. No pats or pcm relation.
