Have an issue, all 4 cams are not moving, just sitting at like -8 degrees
My current combo is a Gen1 FRPP Control Pack, coyote swapped '00 Mustang, T56, 1 7/8 full length headers, JLT Carbon CAI, Gen1 F-150 longblock, stock injectors, 18 intake, new followers, new lifters, Boss 302 valve springs, 3 new phasers and 2 new solenoids, nitrous outlet plate kit.
The problem I'm having is the cams do not move, they just sit around negative 5-8 degrees. Sometimes when you free rev, just the bank2 cams move. Below is the nitrous data log and current tune.
You need to add VCT Schedule mode and commanded angles to the log. My guess is that it's spending a lot of time in "VCT disabled" mode. This happens when it senses some problem, so it defaults to "disabled" and sends the cams to home position as a fail safe.
That said, this calibration is pretty hacked up. Where did it originate? Do you have the stock Ford file you can start over with? Not only are the mapped points in obvious error, there are lots of other problems. It's possible once some of these other issues are fixed, the cams start doing as they're supposed to.
I'm sorry that I am just replying, I get ZERO notifications that someone responded. This tune originated from a NMRA FS tune off a Ford Racing Control Pack. Two different tuners have looked at this tune and have said NOTHING about VCT schedule modes, commanded angle, or said the MAF was a noodle. The car cruises ok and made good power on a dyno.
I am at a total completely loss about what to do and/or change. Fixing to sell all stuff and get a pushrod with a carb. I just want to go racing
I found a stock file & copied nearly everything. Also straightened out that noodle as much as could, but the stock Period #s don?t match mine. Will get a log today & see what happens. Supposed to go racing tomorrow?.
You can change the axis values to match if you click on MAF period inside that table. On the side. And compare and copy over. Then it will match
The JLT intake will probably not like the stock MAF curve. Will need to be adjusted. You might be able to find the MAF transfer data from JLT or somewhere on these forums. Or you can add 10% or so to the entire curve and start from there.
Ok, the VCT schedule is going to OP, as it should. And the commanded cam angles are following OP, as they should. But the actual cam angles are not following the commanded cam angles and this is true for all 4 cams. The next thing I would do is clean up the log list so you can focus on the problem. You have some redundant PIDs and still have a lot that are unnecessary and slow down the data rate. Add cam error and VCT solenoid duty cycle for all 4 cams. In this way, you can see if the logic 1) recognizes the error and 2) attempts to correct it.
By chance, is your engine oil temp hooked up and working properly? I don't see it in the log and it can most certainly limit the cam phasing if it's not getting a good number. Also, under Engine Diagnostics/general/temperature sensors it shows ECT sensor is disabled but it is reading in the log. Might be worth trying to switch this on to see if its affecting phasing.
I'm using the FRPP Control Pack, every sensor is plugged in on the engine harness, even plugged in the oil pressure switch behind the oil filter. I have an adapter that allows the use of an aftermarket oil pressure gauge along with the stock one. All it shows on the log is low oil pressure warning. I have no idea where the Oil Temp Sensor is, unless what I plugged in is the oil temp sensor, not oil pressure sensor
