Can you post your stock file, Im seeing a couple of things that aren't adding up..although I only see a couple of small issues in the idle that may be your stalling issue, I would like to see what your stock file shows so I can see exactly what all has been done.

Also modified the boarderline spark tables and a few other tweaks for a 93 octane tune. Taking it to the track tonight to get some logging in. Not sure if Ill have time to make changes, but definitely want to get some good logs in, both with hptuners and my other handheld (more parameters) and compare the two.

Im attaching the file if anyone wants to take a look at it. Car runs great, no wrench/check engine lights, and overall great drivability

Sounds great! Could you be more specific as to what was changed in your tune for the cammed part and what you changed for the 93 performance part. I have a TVS sc and would like to make this work for it. If I understand the logic behind the tune, you are taking part of you upper range on the VCT tables and copying it in your idle and low rpm range? Then making changes like you would on a car with bigger cams to get it to idle? Looking at your tune, I take it you are M6. I'm A6, if that makes a big difference.

Bill271974, I had a feeling you had copied every table from that tune I posted to yours, and that's a HUGE problem for your drivability. The only tables that needed to be were in Idle and in Airflow/variable cam tabs.

I am going to attach a series of pictures that will hopefully get everything straightened out as I can't modify the tune you posted without buying the rights for the vin. It may take multiple posts due to the picture attachment limit.

I have never dealt with the auto trans and cam part together. From what I have heard/read, there are multiple issues with doing the ghost cam tune on an auto equipped car.

The tables that need to be changed to play around with the ghost cam tune are
IDLE TAB
General subtab:
Enable RPM error raised
Minimum VSS lowered to 0
Rpm subtab:
In gear and park neutral values raised
AIRFLOW TAB
Variable Cam subtab:
Mapped points - Intake and exhaust valve closing (for points 0 and 1) these will control cam timing at idle and allow you to dial in overlap

Also, may want to raise the RPM min to above idle rpm in the engine diagnostic/misfire tab to avoid CEL while running the tune.

Well, I gave it a shot, but it would not run or idle for long. It would crank and surge from 2k to 800 a couple of times and the rpm kept lowering til it died. I'm still learning the basics and this is out of my league for the moment.

I just bought a new 5 liter and I am going to Ghost tune it. It is an automatic. The guys over at MPT say that the auto cars can't handle the overlap that the M6 cars can handle. The call the auto ghost tune a stage 2 lope and the M6 can handle their stage 3 tune. They won't tell me specifics, but I would just keep in mind that the auto can lope but not the aggressive lope heard on youtube.

Anyone interested can PM me and Ill send you a PDF I put together on the basics of the cam tune, file is to large to upload directly to the site (376kb). I hurried through it so hopefully I got all the steps, as its been a while since I have done one.

EDIT: Try the link, its a free upload site, just have to ignore/close the "Flash player may need to be updated" advertisement pop up thing.

Thanks for all the hard word putting that together Toyo! If I have -30* Intake timing and 20* exhaust timing, that will give me 50* of overlap?

Well, the reason my tune would not run was a unit conversion problem for the injectors. I corrected that and it runs! :yay::yay: It didn't stall when I put it in drive either. I'm playing with the cam timing now to see how much lope it can take. Thanks Toyoguru for all the good info!

that file from the link doesn't open. Says invalid format. If you send it to me, I'll see if I can host it.

Here's a link to my tune. I haven't tested much, because it still has cats. I did drive it a couple blocks and it didn't stall.

Sounds great! I'm kinda curious how much overlap you were able to give the cams with a blown auto car.

-40 and 30. So 70* of overlap. I did drive it and it didn't stall but it almost did. It needs some more work.

Good deal man, glad you got everything together and working. Hopefully you get the stalling issue ironed out. Im sure its just a couple small tweaks from being right!

Just put my ORX on, so I will be sorting this out a little better.
