I've used a few clones and they've all worked well. I think the downside is that they may not be as fast as the $100+ devices, so you may not be able to log data as fast.
Here's the pricier versions.

OK thanks for the info. I wont be using my smart phone since
I dont see one that works with BlackBerry phones.
My laptop has BT onboard so no problem.
Would be nice to be able to check things out right on my phone tho.

If you're using your laptop, I would recommend going with the modified USB ODBII cable, so you can use the INPA software, which is very powerful.

Just wanted wireless connect.

No, BMW 1.4.0 dongle will not work with INPA or NCS Expert.

I assume your mileage increase was mainly from the thermostat change out and now the temperature is running above 90C?

Have you changed your intake boots?

You likely need to replace your thermostat? See this thread - http://forum.e46fanatics.com/showthread.php?t=964491

CCV is another major problem area. CCV lower oil return hose is almost always the first part to go bad and is very easy to check.

Also you may want to check out the 2nd link below in my signature as well.

Not sure you have a fuel pump issue, but if everything else checks out, then this is something you may want to consider?

E4/B1 - Oxygen sensor controller, bank 2, deviation too great, deviation rich
E3/B1 - Oxygen sensor controller, bank 1, deviation too great, deviation rich

The light came on when it was in town warmed up.

it still idles low in gear but not when its cold

I used to have secondary air pump codes running to lean. Running the seafoam into the line directly. white smoke coming out the exhaust shows me that SAP is working. could be stuck open. ill check for hot hoses

cleared the code and drove a mile...hasnt come back but i didnt expect it to.
The item for the torque pro app should be here soon.....i should be able to see fuel trim and like you said.....maybe o2 values. I know the o2 needs to be replaced but i do want to find out if thats the cause before i just throw money at it. what gets me.....both banks are banks are rich. the o2 for both banks going out at the same time is unlikely. I may have a vacuum leak causing it to go rich.

at first after the mileage indicator was cleared i ran 27 average for the first 100. now after 168 miles and some in town driving im running 22. This wouldnt bother me because i know the in town should be 19.....but before this problem i have never seen numbers that low....it usually stayed around 25. Doesnt this mileage calculator average what is in the tank over time.....like 27 highway....19 city should be showing 23 or 24 at least. im used to seeing 25 all the time on the dash. it could be 27 hihway and 16 city to give me averages like that

the secondary air pump to check valve hose is shot as well. very deteriorated but wouldnt this only affect the car at cold temps like when first starting even if it was leaking. maybe ill replace it with heater hose. the seafoam basically finished eating it. everytime i touch it now i get black all over my hand

What's the history on the MAF?

cleaned 20k ago.....cleaned yesterday. thats all i know of it. with maf cleaner only. there is an app for the ipad that will tell me maf readings.

it registers like a gauge measured in g/sec numbers 0 to 700. and another that reads 0 to 100 would something like this tell me what i need to know about it

I thought it could be a vacuum leak but figured a leak would cause a lean condition as it would be air coming in post MAF not allowing the MAF to adjust the mixture

Just wanted to know if the MAF had recently been replaced with a cheap online/ebay one.

There appear to be some MAF's on the market that are using thermistors rather than the more sensitive hot film and they under report airflow, but in your case, I would not think this is the case.

Any crankcase leak could possibly cause lean codes, more often than not, a cracked valve cover and/or compromised valve cover gasket can be very hard to find.

Almost all the other problems are basic vacuum leaks that are over looked and/or very hard to locate. Under the back of the intake are the most difficult ones.

But I do have a question, didn't you remove the CCV and install a catch can at some point? Or you were at least discussing this?

The issue is the crankcase in today's cars is actually an integral part of the intake airflow path and have to be treated very carefully.

I looked into it but decided to go against it. Instead i ran a new cold weather ccv instead. I had a 1074 lean code at the time and the ccv fixed that.

it was after all that work was done that it idled low. I replced the disa o ring and the TB gasket, also cleaned the icv but it didnt really need it.

This rich with bad mileage problem is new. Its been going on for about a month now. maybe with the torque pro app letting me know fuel trims will help solve this?


The o2 sensor can cause this but both of them at the same time showing rich?
the MAF could cause rich but sensing wrong amount of air.

BE VERY CAREFUL HERE.

The terminology of the codes you gathered is different to what you might think it means.

Not sure what tool you used to read your codes, but what these codes are really saying is your engine is running LEAN, and the DME deviation is MAX rich and cannot correct the fuel mixture running full rich.

Once you see your fuel trims they will likely be +7% or greater, they will not be running in the negative values.

using pa soft

what could cause that.

I thought it was rich because of the bad mpg

Thought it was likely PA Soft.

I am not 100% but some people had claimed that PA Soft can provide real time data for the engine. I never found that feature as I do not use PA Soft for real time data, I typically use other tools. It may also be for only some engines as well? I may have missed this as I tended to use PA Soft on my s62 M5 more than my E46?

But anyway, what the code means is the DME has deviated to its Rich limit, to attempt to deal with a Lean mixture condition.

It is kind of a semantic issue that will really confuse a lot of people.

VERY rarely does any engine ever run rich, usually an engine running rich is due to fuel pressure being too high, leaking injector or the engine temperature being too low, otherwise there are very few other circumstances where an engine will run too rich, it is almost ALWAYS a lean problem that the DME is trying to correctly by enriching the fuel mixture. This is what your current codes are stating and the issue is the O2 sensors are maxed out in one directly and not able to provide decent cyclical feedback.

i took it for a drive. gas mileage is back down to 21 even on the highway. the idle is low,,,,,unplugging the MAF had no effect on idle at all. pulls fine and has plenty of power. when i started it the idle was fine. i would drop it into drive and the idle would drop to 520 and then shoot up to 7000. i also threw the sap lean code again this time but not the rich code

car should have been in open loop when the MAF was disconnected

Unplugging the MAF will typically put the engine in a fix fuel and maybe timing map. Many times unplugging the MAF will make a lean engine run a bit better, many times nothing other than a few MAF codes.

You cannot really condemn a MAF by unplugging it, usually a bad MAF under reports airflow and usually more so at high RPM, high load situations.

So on to a few other issues.

You say your idle is low, how many RPM and is this with a manual or automatic. FYI, as I recall these cars do not idle very high normally.

How you are determining fuel mileage so quickly? OBC?

At the codes you pickup with with PA Soft Active or Shadow?

Do you know for sure the O2 sensor are plugged in the proper connectors?

You may want to unplug an O2 sensor and see if it triggers a code for the proper back?

ive never messed with the 02 sensors so im assuming they are in the right spots.

the car is automatic and idles in gear just above 500...like 520. out of gear it goes to 600.....when i turn the ac on it goes up.

I am going for fuel mileage by the obc. Since ive had the car it has ran around the 25 range...then suddenly dropped to the 21 range last month. the oil turned dark with less than 1000 miles after it was changed....before i was at 10,000 on the change and it was still slightly brown.

the codes are red and not shadowing. will try to reconnect o2 sensors
