Roland@pcmtec Posted July 31, 2018 Posted July 31, 2018 This is a guide to set up a ghost cam on a BF/FG. This involves understanding how the VCT system in the falcon works. NOTE. This is NOT emissions compliant. This cannot be done on a road car, it must be for vehicles that are used on a racetrack or a powercruise event etc. This is the same as using aftermarket cam shafts. The unburnt fuel will not be cleaned up by the catalytic converter and you will be releasing high levels of carbon monoxide (NOx should be quite low as it is running rich, not lean). Do not leave your car idling in a shed with poor ventilation. E85 is much safer than Petrol however it is still not recommended to breath in the gasses. Firstly the VCT works by the PCM calculating an intake camshaft position, it then adds the calculated overlap angle to this position to calculate the position of the exhaust cam. Eg: VCT_Intake_Cam = Calculated Intake position VCT_Exhaust_Cam = VCT_Intake_Cam + Overlap_Angle. Finally to confuse things the PCM then adds/subtracts from the intake and exhaust cam based on boost error. Note this in only in the FGs. This will not affect idle however it will affect your vehicles performance depending on how you have set up the boost control. To achieve a ghost cam we need to understand how the overlap angle is calculated. There are 3 modes of VCT operation cam source == 4 is Idle mode cam source == 99 is VCT Fault/Not Installed mode Cam source == 3 is power/full throttle mode cam source == 2 is part throttle mode. Now in idle mode the camshaft overlap is capped by the same table that determines the intake camshaft position, so you cannot achieve any overlap, the best you can do is set both the intake and exhaust camshaft to 50 degrees which will give you some lump. An easy solution to this problem is to force the PCM into cam source == 3 at all times. This means the main VCT tables are used at all times making tuning the vehicle much easier. To force the camshaft to use the main maps at all times simply set these scalars out of range to -1000 rpm. auF1079 (VCT Closed throttle disable RPM) set to -1000 auF1035 VCT Closed throttle enable RPM) set to -1000 Now to get a ghost cam the following tables need to be modified auF0115 (BF/FG) Maximum allowed overlap angle based on RPM and Oil Temp. Set the lower half of this table to 80 degrees Now we can change the commanded overlap at idle via auF16492 (BF) auF0116 (FG) Here you can see I have commanded 35 degrees of overlap at a TPS reading of 5, this means as soon as you touch the throttle the cam timing goes back to stock making car parks and low load no problem. You also need to modify auF16503 (BF) auF0097 (FG) to have similar timing values in the low load/low tps cells. In this example I set 600 rpm to -30 deg to stop the vehicle from stalling, this will also increase the lope when the rpm drops low as the decreased overlap will kick the rpm back up again. I changed auF0494 (BF) auF16487 (FG) (TPS) axis to 5 in the lowest cell, this means you keep the commanded overlap when hot/cold. Finally I suggest increasing your idle rpm to 1000 rpm to avoid stalling. In the FG there is an overlap adder for speed density auF2260. You will need to put smaller values in the 30 and 60 degree overlap cells. This will clean up the idle fuel trims. BEWARE that some FGs command 30+ deg of overlap when coming onto boost, if you modify this table you may be modifying the WOT fueling as well. If you are using a multi-tune another way to clean up the idle AFRs is to simply add the slope of map table to the tune. auF2928 may be a more suitable table to use for the FGs as it also has an RPM component. It is also recommended to disable LTFT when the ghost cam is active by adding this to your ghost cam tune. This will prevent closed loop fueling from maxing out adding fuel (auF0164) Beware that if you command too much overlap you will foul your plugs and the car will misfire until they clean up. 35 degrees is quite a lot and I would only recommend this as gimmick not in a daily driven car. Here is a video of what the above settings will sound like. As you can see low speed reversing etc is not a problem. Edit: This is possible to do on a BA if you use HAAT3VC or possibly HAAT2xx as these are the late model FPV BAs that had independent cam control. Here is a procedure to upgrade a BA to use the F6 operating system Edit 2: You can increase the lope quite dramatically by modifying this table (auF11706). This is the proportional gain of the idle spark feedback algorithm. By increasing it to 5000 it will toggle between min spark (-7) and max spark (MBT ~25 deg) causing even more lope. This table is only available in workshop edition. In the 5.0 Coyote v8s we have found the figures below tend to give quite a good result without even touching the cam timing. There can be a hesitation when transitioning from idle to throttle, so you may need to add timing to the low load main spark map to help the transition. In the 6 cylinders the numbers don't seem to affect drivability much so you can put silly figures like above without issue. If you are using the multi tune to do ghost cam you can add the following table to the ghost cam tune to increase your idle rpm, this means the non ghost cam tunes can retain a completely stock idle rpm. Here is an example of the required tables in a BF to add ghost cam to to tune 4 only if utilising the multi tune functionality. Value files now available for FG and BF 3 Quote
fordsrule Posted July 31, 2018 Posted July 31, 2018 i'm keen to try this but is there a possibility of doing damage? thx, steve Quote
Roland@pcmtec Posted July 31, 2018 Author Posted July 31, 2018 If you have stock cams providing you don't you don't touch the tables such as "Expected position of cam hardstop" you will be fine. If you change these tables you run the risk of hitting the physical interlocks to stop the cams from causing valve piston interference. If you run aftermarket cams and extend the overlap even further again (no one would do this) via the VCT system there is a possibility of valves making love to the pistons depending on the cam design. The only other risk is fouling your plugs if you leave it idling lumpy for a long time without your air fuel/spark being correct. However that is no different to running actual cams Quote
fordsrule Posted August 1, 2018 Posted August 1, 2018 ok, i understand. i drive in traffic quite a lot to and from work, do you think that fouling the plugs would be an issue with the ghost cam tune? i have the FG mkii XR6 na. cheers, Steve Quote
Roland@pcmtec Posted August 2, 2018 Author Posted August 2, 2018 Depends how much overlap you command and how much idling you do. Just tweak it until it drives how you want. Take your laptop with you, you can always adjust it. Quote
DarkHorse Posted August 2, 2018 Posted August 2, 2018 You can clean up your fueling by adjusting auF16657, Exhaust cam adder. Under speed density. 1 Quote
Roland@pcmtec Posted August 2, 2018 Author Posted August 2, 2018 Yes if you do this your trims will max out at idle. Fixing the various sd maps will be required as suggested above. Quote

Just want a little "tiny" rattle from ghost cam ? Very tiny bit Quote
Roland@pcmtec Posted August 30, 2018 Author Posted August 30, 2018 It is the TPS vs cam angle. So it depends what TPS angle you are seeing at idle as to what you need. Eg if you set the low TPS cells to a high overlap but when you flick he AC on it the TPS increases it will drop you out of that cell. So you need to experiment and see. Quote
richardpalinkas Posted November 5, 2018 Posted November 5, 2018 Just touching base on this, has anyone fine tuned their ghost cam settings and willing to show what they have found works best for drivability too? Mine tends to want to drop idle rpm too much coming back into the overlap cells, even with idle speed set higher Quote
Roland@pcmtec Posted November 5, 2018 Author Posted November 5, 2018 What fuel trims are you getting at idle? Quote
richardpalinkas Posted November 5, 2018 Posted November 5, 2018 I will double check in the morning. Even with 35deg overlap, i barely get much lump, would running e85 have an effect on this? The effects were a lot more noticable on 98, on e85, same settings seems to just "stumble" rather than have a lump. Maybe the fuel trims are off Quote
richardpalinkas Posted November 5, 2018 Posted November 5, 2018 So i checked stft and they were at 1% with the stock overlap adder for fuel. Changed to the settings in the 1st post and its still at 1% but sounds better. Quote
Roland@pcmtec Posted November 5, 2018 Author Posted November 5, 2018 What about LTFT they are the ones you care about. Quote
richardpalinkas Posted November 6, 2018 Posted November 6, 2018 (edited) With stock cam adder values, around -10. Lowering the numbers for 35 and 60 degree overlap brings it down to about 8, but cant lower it further, and thats lowering them from 1 to 0.5 Edited November 6, 2018 by richardpalinkas Quote
richardpalinkas Posted November 6, 2018 Posted November 6, 2018 So adjusting auf16657 in the 30 degree, 550rpm to 1000rpm, should these values be increased or decreased to make it leaner? Quote

richardpalinkas Posted November 25, 2018 Posted November 25, 2018 Got all the fueling sorted. Sounds good in park/ neutral but driving still has the issue of overshooting below idle rpm, sometimes stalling. Ive tried gradually reducing the cam angle so its not as sudden, which doesnt make too much difference. Is there more parameters that nees to be adjusted such as idle airflow or spark timing at idle to help it not overshoot? Quote

Definitely recommend setting the idle rpm higher and also more airflow at idle. If you raise the airflow to get the idle timing lower (eg 5 degrees ish) then you have more timing reserve to catch the fall. If you are already idling at 20 degrees the PCM can't respond quick enough to catch it. Timing cause the idle to jump almost immediately, more idle air has a small lag delay and can oscillate. I also recommend leaving the oil temp table fairly standard, that way when the car is cold it won't have the lumpy idle. Quote

Roland@pcmtec Posted July 3, 2019 Author Posted July 3, 2019 You also need to modify these tables as they limit overlap as well. auF16503 Angle to Overlap exhaust cam auF16492 Maximum overlap allowed auF0115 Maximum allowed Overlap Angle based on RPM and Oil Temp Quote
Roland@pcmtec Posted July 4, 2019 Author Posted July 4, 2019 Use some intuition. If you are just guessing and blindly plugging numbers in you won't ever get results. If it isn't working datalog why it isn't working. Quote
Roland@pcmtec Posted July 7, 2019 Author Posted July 7, 2019 Update You can increase the lope quite dramatically by modifying this table. This is the proportional gain of the idle spark feedback algorithm. By increasing it to 5000 it will toggle between min spark (-7) and max spark (MBT ~25 deg) causing even more lope. You can also set 600 rpm to -30 deg overlap, this will stop the vehicle from stalling and cause even more lope when the rpm dip as the decreased overlap will kick the rpm back up again. If you are using the multi tune to do ghost cam you can add the following table to the ghost cam tune to increase your idle rpm, this means the non ghost cam tunes can retain a completely stock idle rpm. 1 Quote

Are these tables you refered to just the idle inlet and exhaust overlap settings? Just trying something different that's all Quote

Are these tables you refered to just the idle inlet and exhaust overlap settings? Just trying something different that's all Yes but it was quite a bit of work as there are about 10 other tables you need to access. It is much simpler to just set the closed enabled/disable scalars to -1000 and then set the main cam maps. Then you can just modify the intake camshaft only. This is the same way you can get a mild ghost cam on a 5.0 which doesn't have overlap control. Quote
Roland@pcmtec Posted November 19, 2019 Author Posted November 19, 2019 Updated the main post to add these numbers which work quite well for a coyote 5.0 to give it a "ghost" cam without actually changing the cam timing. Cam timing can be modified for more affect but this gives it a mild lope. auF11706 Quote

The file template level is professional. Quote
Roland@pcmtec Posted December 14, 2019 Author Posted December 14, 2019 It is only in Workshop level at this stage as we spent a fair bit of time researching to find and test it. Quote

Hey Roland. Thanks for the speedy response. I’ve had a bit of a crack myself-I’m OK with altering my GS tune to the equivalent of a GT335 and I’ve got a waaaaay better traction control than the factory ever gave me. However, I’m certain there’s a lot more power/torque on offer with E85 and a set of tunes from an experienced workshop than I’m willing to push with my limited resources. I think I’m best to have a chat to one of the workshops who have runs on the board with your software. Cheers, Ben 1 Quote
