Hi guys, I use the HP software and very farnilif with GM but looking at an xr6t and wondering where I correctly can measure the load. There was no conventional VE table, and I know the injectors have been calibrated correctly we are just raising boost pressure so I was wondering where we go in HP to correct any errors. Or even point ms towards a link that explains the system.

Cheers

Can you give us more background on the project such as mods? This is the 6 cylinder turbo DOHC with intake and exhaust VVT?

Modern Dual VVT engines with stock ECUs don't have a simple VE table. There is a whole set of gasflow model tables depending on VVT position. Search online for the Cobb Ford tuning guide.

It's totally different from tuning say an old LS1, or even a virtual VE based GM engine.

Car mods is an upgraded rear housing on the turbo changed to high mount. All the airflow are in cam angle degree and has been tuned properly by a guy with hp tuners who doesn't just dick around with the fuel figures to get it right he tuned it with HP tuners, has ID1000 injectors. Just got a customer with simple mods and it's completely non conventional like the Holden's are.ita all cam angle v whatever I would have sworn I'm over Looking something. This car is tuned and tuned correctly I just didn't do it so I can't compare to stock to see what had been changed. I would expect map vs rpm somewhere but I can't find it in airflow. What measures the airflow in these? A demo would be great we seen heaps of GM on hp tuners XR6 is not a thing like it except I use same software. Got me beat

Post screenshots of the tables you are looking at.

Ok will do I'm heading out there now under airflow I'll screen shot every thing I can do to do with airflow on the HP tuner and I'll show you. If you are from America these vehicles were only delivered to Aus and NZ. They are a straight 6 twin overhead cam with dual vct and a gt35/82r internal gate turbo. With valve springs and injectors these do 300 on like 12 Psi but I cant get anything that looks conventional I'll be out there in about 45 min

Lots just adjust the fueling side but as the lecturer mentioned that also puts you in the wrong area with timing so I need to calibrate the air correctly it's pretty easy to do the fuel side which has been done on this car and this car has had the VE tables changes correctly this wasn't tuned dodgy but Its got me beat. I'll show you all screens under airflow

Post at lunch ran out of time at smokeo

Hi Damien, it might pay you to take a look at this thread over on the HP Tuners forum - https://forum.hptuners.com/showthread.php?48134-Speed-Density-on-the-BA-BF-Australian-Ford-Turbo-6
