Apologies if there is a really obvious answer to this question that I'm not seeing! Is there a list somewhere that ties the stock file catch codes to the actual model and year? Looking at stock files is a great way to learn what Ford changed in various tables. I knew the BA F6 code which was useful to compare against by BA XR6T file, but the changes aren't significant in relation to timing etc. Looking at say an FG F6 etc would be useful.

This was useful mate - thanks! It was one of the strange things in my tune that I thought was sus (thought my car was stock but turns out it wasn't). Needless to say I've turned it back on.

Edited the original tune last night to match the stock HAANFHZ strategy and flashed it in. The compare feature and apply feature are both excellent! Main things to revert were the boost control, some base fuelling (At WOT and high RPM, was set leaner than the factory tune!) and turned cat overtemp protection back on. End result is attached. There were also some differences between HAANFHZ and my file in relation to some torque management and transmission tables. The changes seemed a bit more extensive than the rough approach taken to boost, etc. so I'm a bit suspicious that these could be an official strategy update or something at some stage. I haven't put these tables back to match HAANFHZ yet. If anyone is familiar with these tables and has a view on whether they look modified, that would be great (ie comparing my file to HAANFHZ). The other interesting thing is that my file refers to HAANFHZ/A3HD. Whereas the tag on my ECU refers to 3R23-12AB50-AHA and A3YA. Not sure if that is relevant, but made me a bit reluctant to change things other than those that I was 100% sure were different to stock. I'll drive it for a couple of days on the current strategy to make sure everything is behaving itself and then start on my boost control and fueling tables. BA XR6T A4 2004 return to stock except trans and torque mgmt.tec

Thanks Darryl! Yes, I think you are correct. I ran a file compare against the stock strategy (excellent feature by the way!) and it showed me a few other tables that have been modified too (a bit of timing, some transmission tables, etc.). Given I've got no idea of the source of the original tune I'm not inclined to trust it, so I think I'll use the file compare feature to set my tune back to factory. Then I'm starting my tuning from a known base. I'll drive it for a bit on the stock tune to make sure everything is working as expected and boost control is fine. Actually, if you are interested in the file I sent it to support on Tuesday as Roland was troubleshooting a licensing issue for me. Keep up the great work guys!

Hey everyone. First time tuner here, trying to learn on my 2004 BA - so be prepared for some dumb questions! Hopefully my early learning will be useful for someone doing the same. Car is completely stock tune-wise (as far as I know) and hardware wise just some supporting stuff - high-flow cat, twin 2.5" cat-back, wideband, boost gauge, oil pressure gauge, fuel pump. About to put in a trans cooler for the BTR and a bigger intercooler. More detail of the mechanical stuff will be here http://www.fordxr6turbo.com/forum/topic/93864-ba-turbo-build-thread-sort-of/ So far I have just done a fair bit of reading on forums and books to try and get a feel for how all of this works, particularly Greg Banish's Engine Management book. My first round tune will aim to up the boost pressure to maybe a max of 9 PSI, plus richen up the AFRs accordingly. Later on I'm planning to give it more boost and a set of new injectors. My first problem is my desired boost table (auF0306). It looks like this: If I look at the stock files for my strategy (HAANFHZ), the table looks much more like what I would have expected. Similarly the wastegate duty cycle table is a flat 0.45 across the board. My boost gauge only ever reads about 6 PSI, so it is obviously not even trying to reach the sort of boost that is in the map. So I'm thinking that maybe the car has been tuned before, but in a very unusual way? Now that I write that, about 2 and a half years ago I had a new turbo core put in. I had previously fitted a new boost gauge teed off the BOV and removed the hose from the old gauge to a contraption I assumed was a boost pressure sensor specifically for the gauge. The turbo place that did the CHRA replacement said there was some sort of weird boost control device hooked up to the turbo, which he removed but couldn't work out how it functioned. I said nah, its just the sensor for the old gauge. Maybe the car had some sort of boost controller hooked up (I'll see if I still have it floating around the shed for a pic) and the tune boost tables were just zeroed out so that this device did the boost control? And now that the device is out, the boost I'm getting is just a function of load/WG spring pressure and the WG duty cycle table? Any thoughts or suggestions would be great! I'm thinking I probably need to reset my boost control tables to match the stock strategy, flash that and see how it behaves? Or any thoughts on why else my boost tables would be so whacky? Base fuel table is untouched compared to stock strategy. AFRs are bang-on what I would expect too, so I don't think the tune has been beaten-up too much otherwise.
