Mitch1987 Posted April 9, 2021 Share Posted April 9, 2021 Hi new to all this I have a 2014 fg Xr6 turbo and it’s been tuned with pcmtec normal on tune 1 and tune 2 is same tune with ghost cams if I slightly touch the accelerator it will hunt between 500-1000 rpm same when slowing down and level out after about 3 times is there something in my tune wrong ? That you have come across thanks Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted April 9, 2021 Author Share Posted April 9, 2021 You need to speak to your tuner. Ghost cam will always have compromises. Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted July 30, 2021 Author Share Posted July 30, 2021 Reverse Ghost Cam Thanks to Stathi at IMS for his time and perseverance we have a procedure for doing a reverse ghost cam. This allows you to close up the overlap at idle or change the intake cam angle. This procedure was tested on an auto FG, this should also work on other vehicles however we have only been able to test it on an auto FG. You will need to experiment with what angle works best, it may be positive or negative depending on how the cam shafts are degreed. Intake only First ensure the scalars used to enable a ghost cam idle are set back to stock auF1035 == 1100 auF1079 == 1200 auF0102 set to 20 auF0100 set to 20 auF0103 set to 20 VCT angle auF16610 set to 20 in the idle range VCT angle auF0115 set to 20 in the idle range VCT angle auF16501 set to 20 in the idle range Beware that with a large camshaft the TP can be as high as 160 at idle and the load as high as 0.5, so you need to cover a lot of the table to get this to work as expected. You may also want to tune your spark timing at these higher loads to assist with bucking and jerking in carparks. To get the exhaust cam overlap to close during idle up the best method is to simply degree the camshafts so there is no overlap when installed. If you cannot do this then you can close up the overlap at idle by setting the following tables This will cause the exhaust cam overlap to close up to -20 when in CAM SOURCE == 4 (idle mode) when CAM SOURCE == 1 (in gear) we couldn't get the overlap to close up (eg an auto in gear). We found that the overlap being at 0 actually gave a stronger idle however so we did not persist with making this work. In a manual this would be not be an issue. auF0098 set to -20 auF0097 set to -20 auF0116 set to -20 This combination of tables is fairly specific as we found auF0115 (max overlap vs oil temperature) is also used as a "max intake camshaft position) when in gear. This was required to be set to 20 to get the intake camshaft to do what we wanted when in gear. The actual angles to use for the best idle will need lots of experimentation as it depends entirely on the camshaft aggressiveness and how they have been degreed, eg do they have overlap built into base position or not. Here is a log showing the idle camshaft angle and load. This showed an idle of 0.36 load and 19 inHG/ 61 kPa Happy smooth idling guys! 4 Quote Link to comment Share on other sites More sharing options...

BeerTurbo Posted October 10, 2021 Share Posted October 10, 2021 having a play with vct tonight, just to see if i could advance exhaust cam fully on decel to aid in possible decell flames. the scallers for decel cam angle dident seem to change anything. changing the angles in low low etc etc definatly got them moving, but i would prefer to work out how to make decel cam work instead. for testing i saw a max of -10.4 or 63.7 degrees cam actual on the exhaust cam. within the paramaters i gave it, there was the ability to go more but it did not seem to like going past -10...so maybe thats where max is? even just cruising and the exhaust cam at -10 you can smell alot of fuel leaving the exhaust. 1 Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted October 10, 2021 Author Share Posted October 10, 2021 The logic is a bit complicated as there is max overlap vs max exhaust cam and also max intake cam. You might have to adjust the intake cam position as well at light load high rpm to get it to do what you want. I believe there are some closed throttle scalars as well with load and tps that decide when it's in closed throttle mode. Quote Link to comment Share on other sites More sharing options...

I believe there are some closed throttle scalars as well with load and tps that decide when it's in closed throttle mode. yeah I had the intake set to 0 and requested overlap -15 and max overlap -15 and it was still sitting around that -10. interesting enough it would do this at idle too , so it seemed to ignore the idle setting and go straight of the main tables. the decel exh cam setting has a -18 option so tonight ill see if i can play with enough settings to see if it will go further... but also looking at max negative cells -10 does seem to be what factory uses. i had a play with these last night as the way its worded i thought maybe vct will only go to closed throttle mode from 0-1300 rpm but i could be reading this wrong.

Callum Posted November 22, 2021 Share Posted November 22, 2021 Howdy guys, not long purchased pcmtec pro to tune my ba xr6 turbo manual and wanted to give it some ghost cam along with my buddies bf mk2 xr6 na zf. My manual wasn't too hard at all and seems to work great however the bf I just couldn't get stable. Now matter how low I went in overlap it would hit overlap drop a heap of rpm then jump back up and just keep reving up and down. My ba xr6t very slightly does this only once or twice before settling fine with 30 overlap. Any input into what I might be doing wrong would be excellent. Tried fiddling with rpm but being auto going too high loads up the tc too much and too low and it'll stall. Loving the program guys excellent work 👌 1 Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted November 22, 2021 Author Share Posted November 22, 2021 Is your cam timing oscillating? Show us a datalog of it happening and post the file up. It might be hitting the anti stall or the cam might be oscillating more than you want due to your load kicking it out of the overlap then back into it. If the cam is oscillating all you need to do is datalog what load and rpm it occurs at and adjust the cam timing there. If you find the rpm is dropping too low hitting the anti stall I would reduce the overlap and put -30 at say 600rpm as your own anti stall to stop it going that low. Anti stall kicks in at about 350rpm from memory. Quote Link to comment Share on other sites More sharing options...

Could you take a datalog showing the tp, rpm, commanded cam angles, angle error and cam source. Try touching the throttle a tiny tiny amount and set the ghost cam to work up to 1200 rpm and see if it works. That will see if it's the idle mode being the issue or not.

Roland@pcmtec Posted October 9, 2022 Author Share Posted October 9, 2022 Some fairly obvious problems here. TP never drops below 124 and your over lap map only requests 0 deg between 5-250 TP I can't see engine RPM in your log but make sure you are idling above 900 rpm also. As soon as it dips below 900 its going to go back towards 0 overlap quickly. Tweak these numbers to suit your idle rpm and whether you want the stall recovery or not.

NickIsNotSus Posted September 11 Share Posted September 11 Just a query, i had played around with the ghost idle.. was fun to try out.. i stumbled across and downloaded the param file for permanent ghost cam idle. I'm no expert, I am just learning but i compared the param file to the instructions and found it to be quite different to the settings at the beginning. After flashing the ghost tune from the website "HAEE3_FG_Permanent_Ghost_Cam.param" i had a horrible flat spot going from no throttle to just touching it and made it quite jerky at low idle moving while the revs were hunting up and down (assuming the vct timing was changing). I changed the throttle position A/D counts 10 and 20 set to zero. it still idles the same ? from idle to acceleration is smooth. still a little jerky rolling at idle but i think its probably something thats part and parcel of having ghost cams. its not some i intending on keeping long term. its just helping me get familiar with the software. Is changing these ok ? like i said i'm learning and reading a lot and experimenting ..cheers Quote Link to comment Share on other sites More sharing options...
