Got my OBDII gizmo and messed around with the torque app. I'm impressed, seemed very accurate. What are some values I should be looking for? I was watching boost, max I saw was 15psi. Max coolant temp was 221, AFR was in the 14.6 range. I'm most confused about how to read the timing, can anyone offer some advise? Do those #'s seem right? 12' MCS 6sp manual, 25k miles, I use 93 octane. Its 80 degrees out today, 63% humidity and I'm at sea level. All I have is a JB+ and k&n drop in filter.

 

Also, the JB+ came from the factory slightly above the default 50%. I'd say its at around 55%, I left it at that and have not adjusted it.

 

You should data log and do a couple runs. Look back at data log to see max readings.

 

Timing advance is reading for the #1 cylinder only.

In normal partial throttle and idle it will bounce around a lot and for the most part is meaningless. What you want to look for is during wide open throttle. The ECU responds to knock by retarding the timing in 3 degree steps.

Go and do a 4th gear pull WOT from about 2500 rpm to 6000 or so. Timing will settle at some number and stay constant or slightly increase. If it suddenly drops (by the 3 degrees) then this could be a sign a knock activity.

It is safer to record and play back later.

 

The track recorder add-on for torque makes recording runs pretty easy.

Great, I'll give these ideas a shot. The car seems to be running perfect at the current settings. I thought the boost reading I saw would be slightly higher since its pretty warm in FL right now. Just wondering if turning that dial up another 10% or so would be safe. I don't really want to pay for high octane or try to find ethanol and mess with that. I love the JB+, just looking to see how far I can take it and not damage anything. I don't race and rarely go WOT. Just wantbaome extra reliable power. I am happy thus far though. Thanks!

 

What do you consider high octane?

 

I guess anything over 93 only because that's all that's readily available. I've not looked much but never noticed E85 around here. I have seen race fuel. I think it was 105 octane. I could mix it. Is it better to mix a higher octane or E85? I wouldn't want to mess up any sensors using E85...

 

Just looking for a little more reliable power. I'm under warranty for another year otherwise I'd just upgrade more stuff and get a tune.

 

You might look at a W/M injection system, you can choose to use it for cooler intake temps or tune your meth kit for a huge boost in octane rating without having to buy race fuel or a tune.

 

Your temp seems high, mine is around 190F always, even at 23psi

It does seem high. I'm new to the mini world and from what I've researched, looks like they do run pretty warm. I thought 220ish is about right. Can anyone else chime in?

 

Having a Mini operate at 226F might not seem bad in a cold climate (UK) but here in the stated where temps approach 100+ F 226F seems nuts!

 

221F (105C) is pretty normal for our cars unless driving all out (several full throttle gear runs will drop it). I see the same.

Full cold ac on high fan will drop it on all cars to the lower temp (~85C/185F).

On later years (2012+?), the sport button drops the temp as well.

Mario, the GP2s are programmed to run cooler all the time.

The thermostat housing is a dual path unit to alter the temps as it sees fit. You get better efficiency and fuel mileage at the higher temp but can be more prone to predetonation.

220ish is right.

 

What app are you guys using? is there an actual app named "Torque" for iOS? Is it free or pay?

I have been using DashCmd for a while, but I don't see a record feature.

Thanks

 

My 13' coupe runs about 220ish normally, and around 190 with sport button depressed. Also I would slow down on turning up the JB+. 50% (factory setting) is what is recommended when your car doesn't have any mods to support turning up the JB+. A K&N drop in filter isn't one of those mods. You should read the JB+ thread .

 

I am using "Torque" on android. I'm not sure if it's available for iOS. There is an add-on for it called "Track Recorder." It's pretty cool, takes video while showing you the gauges you choose to monitor. I haven't spent a whole lot of time messing around with the app, but I'd like to find out how to log the info on to a graph, especially the timing. It's too difficult to just watch a meter and determing proper timing. With boost, AFR ect., the gauges are pretty easy to just watch after a run to see where you're at. Can anyone give any insight to how to get the torque app data on to a graph for better analysis?! Also, I just found a station that sells E85 close by, going to do a mix with 93 octane and turn up the dial a little once I figure out how to properly use this app!!

 

I've read the entire JB thread since I started this thread and I didn't really come across any "supporting mods" for the JB. Higher octane and the ability to moniter the data is what I got out of it. W/M or a FMIC can help but from what I've read they're not as essential as raising the octane. Did I miss something? It was a long thread!!

 

The important thing is to reduce the possibility of knock which happens to be the main function of all the things you mentioned: higher octane, intercooler, W/M.

 

Agreed, and I wouldn't even feel comfortable with going 100% on the JB even if I had all three of those working for me. I'm still under warranty so for the next year or so, I'm going to keep the mods and tinkering to a minimum. Just trying to learn how to monitor the data and see if mixing E85 with 93 is worth it with turning up the dial alittle past 50% on the JB. Sounds like there has been some success that is still in a "safe range" of operation. And that's all I'm looking for right now. Thanks!

 

You might find that there is a sweet spot on the dial. When I had my JB+ it was around 70-80% (I was using Torco)

 

I'm also trying to get meaningful data logs from my Android + Torque App.

 

Since the JB+ fools the computer into providing more boost, is the Torque app reading actual boost or what the computer thinks is max boost? Since it is OBD II, I think it is reading what the computer thinks is the boost whereas the actual boost is higher using the JB+.

The data from the OBDII port is from real sensors in the car. The PID for reading boost is calc.boost_pressure which is sae.map - sae.baro. It is the actual pressure in the intake manifold corrected for barometric pressure.

So the boost reported by the OBDII port is accurate.

The JB+ works by altering the mass flow rate signal which is a different sensor.
