Fg Xr6T Tuner Help Required

[FGX 40T]

I have an FG XR6T2009 6spd ZF. Car has stage 1plazmaman pipe kit, FG F6 injectors and a custom tune. I have searched the forum but can not find a solution. Since the car was tuned with mods the car has an intermittent stalling issue. It has been back to the tuner many times for no result. The car drives perfectly and idle seems ok in Park and Neutral. The stalling happens as you pull up to a full stop. Sometimes it's fine other times it stalls. The car seems to hunt a bit at idle (in drive) revs drop very low the car shudders a bit as the car tries to recover the idle. Are there any tuners out there with some advice. My tuner has said he does not know what is causing this issue and what more he can do. I am at the point of returning the car back to stock but since now I have blown off my warranty I would prefer if someone could assist me with this issue. Sorry for the novel- very frustrated

Sound exactly like the issues they have with nissans and toyota's when they tune them with the AFM to close to the turbo..

No idea about what sensor arangement fords run as I'm only new to them. But as already mentioned. Its a tuner issue..

the idle may have to be lifted a bit 250 r.p.m max ( 550 ) is normal, but before u do that clean the throttle body really well this should be a decent fix if its only every now and then , I had this issue a wile back t/b clean normally fixes it

As you already know I am trying to work this one out. I spoke to someone who sold his FG F6 because of this problem. His car was stock and under warranty and Ford could not fix it.

Its just one of those niggly computer problems. Is it software, could it be hardware. Not sure yet.

Mine was tuned by XFT and he couldn't solve it at the time. He said the problem was there prior to the tune. That was a 6 months ago. Maybe now he may have a solution.

I was doing some datalogging the other night. Datalogging shows the timing spike at 5km/h. 5km/h is the switching point for addaptive idle control. So when it goes from decel timing to addaptive there is a reference to the MBT table.

I am going to datalog the spark source codes via SCT livelink this week and this will give me a better picture.

Is it the same problem as yours. Dunno, but if you datalog yours and the timing spikes sometimes when it switches to adaptive spark idle control them maybe it is.

Raising RPM helps but the problem is still there.

It was happening to me when I first got my car tuned. Spiro from autotech diagnosed it as being a faulty o2 sensor. He replaced it and I've had no problems since.

I've presently got a car doing this and have made a few changes from normal that shouldn't need to be adjusted but appear to be making it better, But believe SCT may have messed up something with the tune data ?

My car did this ages ago.. Used to have to chuck it in 'N' (auto) when coming to a stop, so I could start it back up in time if the lights went green, it happened that often. It would drop revs and shut down when coming to a stop.

I dunno exactly what fixed the issue, it either went away itself, but I also changed tuner so it might have been that, but as far as changing any hardware to fix it, I didnt change anything. I believe its a software issue. This topic gets brought up every so often you;d think we'd know what the go is by now..
