Are you trying to use a laptop with scanxl to talk directly to the car?

Curious about this as well. I thought you had to log with DashCommand, then use ScanXL to read the data.

Yes definitely. We would also have to agree on a test method too. Ex: flat land, 3rd gear, 3000 rpm to red line, 5 runs take the average. Regardless of the validity of the hp and torque calculations of the app any assistance would be appreciated in picking the best numbers for...

• brake specific fuel consumption (most confusing because it is not really a constant)
• Drag coefficients
• Frontal area

The brake specific fuel consumption setting adjusts the hp and torque calculation up and down. Per this post, "Our horsepower calculation relies on the BSFC setting and the calculated fuel flow (which uses MAF, or MAP and VE is MAF isn't available). Increasing the BSFC setting will lower the calculated HP". If nothing is entered it defaults to 0.44 (I get crazy high numbers. ex: 248 hp and 282 ft-lbs). Palmer recommends 0.50 to 0.60 for turbo charged cars (I have been using 0.50 and the numbers seem plausible. ex: 202 hp and 208 ft-lbs). Only found one article listing the minimum BSFC as, "348g/kWh at 2000rpm/2bar BMEP". I think this converts to 0.57 lb/hph. This page gives general BSFC numbers for different types of engines.

My Dashcommand iOS vehicle settings:
Engine displacement: 1598cc (owner manual)
Fuel type: Gasoline
Fuel tank capacity: 13.2 gal (owner manual)
Brake specific fuel consumption: .50
Tire size specification: 205/45R17
Final drive ratios: (NAM VIN Decoder)

• Axle ratio: 3.65
• 1st gear: 3.31
• 2nd gear: 2.13
• 3rd gear: 1.48
• 4th gear: 1.14
• 5th gear: 0.95
• 6th gear: 0.82
• 7th gear: nothing entered

Curb weight: 2668 lb (owner manual)
Additional weight: 150 lb (my weight)
Drag coefficients: 0.36 (here)
Frontal area: 1.99 square meters (here)
Maximum engine speed: 6500 rpm
Minimum engine speed: 700 rpm

Drag coefficients: Hardtop 0.36, Clubman 0.34, Countryman 0.36 (From the TheCheatOSX's service bulletin database here, SIM000210)

Cerenkov,
Hope this helps. Page 30 of attached the CALC PID reference document from the Palmer website.

• Ambient air 42F; 50-90 run; 15psi boost; engine 221F; IAT = 63F

In all cases the IAT returns to about +2F above ambient very quickly while traveling at speeds of 30mph or greater. Even after the highway run (+21F) it returned to +2F in about 20 seconds.

Pepper I'd be curious if you have consistent temp readings if you replicate your runs with your stock airbox. If so I think that speaks to the effectiveness of a good stepped intercooler. The RIS helps provides a cool (semi pressurized environment) like the stock airbox with the added benefit of a K&N cylindrical element and its reduced air flow resistance. Personally I also enjoy the "etherial" sounds that emanate from the RIS. The downside is it interferes with strut tower brace installations. I also had to modify the rubber seal on top of the RIS to some degree in order to best channel the incoming air from the hood scoop.

Regarding timing and AFR, what numbers should I be wanting to see to make sure my engine is running up to snuff? Or, is there some place someone can point me to know what numbers are desirable?

For the most part you're only need to be concerned about these values while WOT so during WOT or high boost conditions:

1.) AFR should drop to about 12 or so toward the end of a 4th gear pull from 3000 rpm to redline. This means that the engine is running rich which is safer but less powerful than lean. During normal driving this will bounce around 14.7 which is the stoichiometric ratio for gasoline engines.

2.) Timing is going to be all over the place during normal drive but under WOT it will settle at some value - the actual value is not terribly important. Here your looking for timing being retarded (or pulled) due to knock. This can been seen by 3 degree step reductions in timing. This is really only a concern if you have a tune for increased boost and/or using low quality gas.

There is a lot more information about this out there with regard to turbocharged cars (it doesn't have to be MINI specific), personally I like youtube videos.

Have I missed something simple or do I need to change some settings.

Any help would be appreciated.

Thanks and I'll be up and running tonight
