HOWTO: Ghost Cam and VCT simplification


Recommended Posts

Hey I've done this in an FG with HAEE5T4, works great with AC off and in N or P but stops when AC in turned on or in gear.  I can see from the logs the rpm isn't changing but MAP is increasing from 14/15 inHg to 20inHg and that's when the ghost cam stops.  I have tried looking for various TPS maps to see if theres an adder somewhere for load/AC.  Has anyone dialled this with an FG or am I using the wrong OS?  I have the professional version.

It controls idle to rpm used a closed loop airflow and spark controller. So when you turn on the AC the idle drops, this makes the airflow controller kick in and give more airflow which then increases idle back to the setpoint. You'll see that the TPS and the load increases when this happens. To make the car still chop when this happens you need to datalog the TPS and load making sure the cam timing tables have overlap at these two values.

I have an FG Mk1 Manual N/A, code HAEDJC5. Ive got the ghost cam intermittently working after following this thread and playing around with it for a few hours, it works 1/2 the time the engine is running and cuts in and out of the ghost cam  and i cant figure out why, and when it does cut out it sounds like a misfire not normal idle. I've attached my tune if anyone has any ideas. Thanks in advance

Hi there.

We've got a barra converted patrol, running fg turbo motor with the ZF. For some reason after copying over the parameter file, it works perfectly for about 15 seconds, changes spark source from base to idle and after that it seems to smooth itself out and stay on idle spark source. If we give the slightest throttle opening it works perfectly again, but the second you take your foot off the accelerator, the cams no longer overlap, and the idle smooths itself out again in a few seconds. If anyone has any idea that could help, it would be much appreciated. I can post a datalog if you would like, just let me know what pids you would like to see.

 

Thank you!

Turn off LTFT when the ghost cams are enabled, this requires that your fuel injectors are dialed in within 5% with the ghost cam is disabled. Then make sure you lean it out at idle via the overlap SD adder so that it isn't pig rich. Finally I recommend setting up the camshaft timing rpm breakpoints so that at 500-600 you run -30 overlap (a reverse ghost cam). This will make the rpm kick back up if it starts to stall.

Yeah, so that's what, $500 or so?

Wow

Cheaper than an xcal or ngauge. Plus you can change the tune with the engine running instead of waiting 5 minutes. 

Different boost levels, launch control and all sorts are possible. There is no other product that can do this.

Oh yes, i do see that

I just wonder if it's worth it for an NA?

@Roland@pcmtec NO NEED FOR SMART ASS REPLIES , I SIMPLY ASKING WHAT YOU RECOMMEND TO START OF WITH ( ANY OTHER SUGGESTIONS THEN STARNDARD ) , BUT I HAVE NAILED NOW THANKS ANYWAY NO WHERE NEAR YOUR GHOST CAM PARAM BTW. ALTHOUGH I DO UNDERSTAND ALL VEHICLES ARE DIFFERENT.

That is because there is no answer for the question you are asking. It depends how lumpy you want it and also the misfire limit with your injectors and spark plugs. Anywhere from. 28 to 34 deg of overlap is what people typically run and what was put in the howto guide. You need experiment and take videos then ask for help, eg this is what I have tried, here is a datalog and here is the problem I am experiencing. Help other people help you.

auf0111 - vct angle

 

auF0114 vct max retard 

is not mentioned in the how to , what would u suggest a good start for reall choppy idle

That is because intake cam angle doesn't really make any difference. It is the overlap that matters. What is stopping you putting numbers in and testing it out?

Running that rich will likely foul plugs causing stalling issues and wash the bores if you leave it idling like that for an extended period of time.

Definitely turn off LTFT/lean it out at idle in those areas.
