C208 Mods?

[Deleted]

Does anyone here have the Carenado 208 WITH the customer-made mods? I know about Bernt's modified files but not long after the 208 came out, someone at Avsim did a number of engine (and maybe FDE) mods that enabled you to cruise at normal power settings without the ITT being in the red constantly. If anyone here has those mods, could you let me know please? Mine have gone MIA.

Thanks much!

Hmmm, I can't find mine, either.  I've got the FDE's and the gauge mods and the better sound files but I don't see any engine mods anywhere.  Could be I never got them, I suppose.  I'll look again.

Fritz, I think the gauge mods are what I'm actually looking for. I believe that's what fixed the ITT problem. Would it be possible to get a copy of that mod from you please?

Many thanks for your help Fritz.

It turns out that the file I have marked 208_gauge_mods is merely the CAB file for the better cockpit sounds.  However, I did find this in my "tweaks" folder:

TEST RESULTSFirst thing, I'll tell you what I changed:Aircraft.cfg[GeneralEngineData]fuel_flow_scalar = 1.18 [turboprop_engine]maximum_torque = 2040[flight_tuning]parasite_drag_scalar = 0.8Air file (I use Aircraft Airfile manager v2.2.)Entry 1526ITT scale factor 0.95LIMITATIONSAs you all well know, FS has some limitations, so I had to tweak by reaching a good balance with the numbers.EXPLANATIONWhy did I decrease the torque scalar and increased the maximum torque? FIrst I increased the torque value to 2040, as it is a value "unreachable" by the aircraft if not sitting still. We need a 1970 torque during cruise, though. Do you see the red line "TO" at 1865, and then another one at 1970 on the torque gauge? Well ,that's the one. But setting the torque limit at 1865 wouldn't allow us to reach 1970. Setting it at 1970 neither. We need that value, during cruise, at cruise speed with full throttle you won't go over 1970 torque, setting the limit at 2040 in the cfg. Ok.I had to lower the scalar, though, or the climb (and the cruise as well) would be way too fast. Keep in mind I had the manual in front of me, it's not a random number. If you look at the "cruise climb" page you'll see it reaches 12000 feet. Because after that we can't reach 1865 torque any more, so you just keep full throttle and keep climbing. I managed to use that value, 0.85 (it was 0.83 originally, but it seems a bit too low), because in the cruise page I checked the values of torque at different altitudes (ISA cond), and as you can see there are strange numbers, like 1428 at 14000 feet, those seem to be absolute maximum values. But the values for lower RPM are higher! Simply because reducing the RPM will produce a higher torque, but not in FS (or not here, at least). So, if you climb above 10000 feet (about), and you want to cruise fast, just keep full throttle and 1900 RPM. If you want to slow your cruise, you can use lower settings of torque and RPM, but at least our speeds and performance aren't compromised.So remember: climb at 1865 torque and 1900 RPM until you can, monitoring the ITT, of course. Don't use full throttle from sea level, it would be unrealistic. ITT, you need to open the airfile, it's an easy step, just change that value, save and close. I tested it at 42°C at sea level, then 50° sea level with 1700 torque, as per the book. It works. I think it could be lowered a little more, like 0.94 maybe, but 0.95 looks more challenging. And after all, how many times do you take off with 42°? Unless you always fly in the desert...This setting will also control the ITT during climb and cruise, where limits are at 765° and 740°.Fuel flow parameter. Not much to explain here, it was too low, this is the optimal value I could find for all altitudes. My tests were run at different RPM and torque settings at 4000, 8000, 12000 and 16000 feet.Parasite drag remains as yesterday tests, at 0.8, cruise speeds are just fine.CONCLUSIONSYou will get a balanced plane overall. If you are looking to change these values to make the plane as real as you can, you won't cheat. Yes, because you can. Increasing the torque will give you more power available, but it's not our purpose. You will fly it as it supposed to be flown. So take off at 1865 torque (be very careful when incresing the power to TO, or you'll stress the engine), take a close look at ITT temperatures during all critical phases of flight, such as takeoff and climb out. Be within the limits, and you'll have a very nice bird to fly. Gauges are just plain perfect, Carenado style. You have everything you need, so now go fly it!CheersFedeP.S. This was the result of a whole afternoon of testing, we may tweak a little more the numbers, just try it this way, and let me know

That was from some time ago but I did find the thread at AVSIM.  forum.avsim.net/topic/294309-speed-temp-issues/   I'm pretty sure that's what you're looking for.

Ahhh, super! Thanks Fritz. I didn't know there were mods to the cockpit sound. Do you know where I might get that as well (assuming they are freeware)?

Thanks a bunch - I'll copy this in tonight. Much appreciated .

OK, there's a link to a patch with all those mods to the ITT, fuel flow, etc.  at Carenado in the "update" section.  It's called "C208 FSX - Service Pack 20100922" 

Log:

C208 FSX - Service Pack 20100922

Released Sep 22 2010, 2200 GMT

Modifications:

- Drag adjusted (both induced and parasite)
- Climb rates are more accurate
- Flaps drag and pitch adjusted
- ITT adjusted
- RPM change affects torque
- Atmospheric density on torque available corrected
- Engine spool time improved
- Fuel flow adjusted
- RPM needle adjusted

Known issues:
Problem with the door manager. We have detected that some customer have problem trying to open the doors
with the doors manager.
Looks like customers with Acceleration Pack don’t have this issue, but customers with SP2, not the one included in Acceleration,
have this problem.

This package was developed with the collaboration of Federico Bellato and Kreg Earhart one of our Beta testers.

You don’t need this Service Pack if you download the aircraft after 22 Sep, 2010 at 2200 GMT.
You don´t need this patch if you bought the product from any reseller.

As for the sound file, I'll zip it up and upload it and get a link to you shortly.

Glenn, see your PM.

Many thanks for this Fritz. I re-downloaded the airplane the other night so it sounds like I already have the updates then. Having this info though will help in case the issues aren't resolved. Really appreciate the help on this!

See your PM as well please .

[pivo11]

At your service. 

P.S.  No problem for that link.  Plenty of room left in my account.

Hey Fritz, please check your PM.
