Default B58 map 3 issues - 10-16-2018, 03:01 PM

currently running a c-a-tless d-own-pipe, been told by previous owner of the jb4 to run map 3, i added the EWG harness but the FF harness i was sent was incorrect so just the EWG for now, here are some logs, car felt horrendous in 4th/5th gear and this log is 5th gear can see how much the boost drops of throttle closes? any help would be greatly appreciated

TIA kyle

Your IAT !!! What is your ambient air temp?

Maybe load the latest firmware (v11, you are on v8) and try again using default settings on map2

I thought the same when i looked down and seen how high it was (on my phone), ambient temp at the time was probably around 13 degrees celcius, any idea what could be causing such high temps?

Try a firmware update first, I got some odd readings on earlier firmware.

I notice with my car when i turn it off and turn it back on 5 minutes later the IAT are high around 130F and it takes a while for it to drop down to 100F. When ambient is even 55F outside my IAT are still in the 90's close to 100's.

Only issue is those temperatures are in celcius not farenheit

Normal heat soak. After a minute of driving it should go down.

They are in Fahrenheit in the logs, the conversion to Celsius only seems to apply to the phone App display. Still way too high though at 170+ and likely the cause of your throttle closures.

i see, my mistake, run some more logs tonight temps are better. ran in map 4 as i was informed to do to get a baseline for my car. the car felt horrendous, the graph shows the throttle constantly opening and closing so i ran some logs in map 0 which effectively map 4, the car felt like a completely different car pulled way harder. I've sent my logs off to bbs directly and speaking to an employee on the live chat I've been informed that all logs are okay except when running map 3 seems a little too aggressive for my fuelling. but the car just feels quite frankly horrendous on wide open throttle and i have no idea what to do next....

Did you update the firmware? How are your AIT's on map 0?

yeah i completely removed the unit disconnected the battery ensured all connections were correct, then updated the firmware.

map 0 IAT started at 130F and then continued to rise to 148F with an ambient air temp of 50F

Still seems a fair bit higher than I see with a similar ambient. Normally it would come back down to mid 20's C when cruising at 70mph for a few mins, then only go up by 3-5 deg when doing a power run through 3,4,5 gears for example. That's in current UK weather.

the fan is on a lot as well which has never happened before. i know there s a few owners of the same car had issues with stone damaging the radiators, do you think that could potentially be an issue?

Possibly, although the main rad is the only one that has a fan I believe. I don't know if its possible to lose the coolant from the charge cooler without a check light showing up?

you'd think so but I've heard a few people had issues with aircon not working, taken it to BMW and then they have been informed the charge cooler and rad is wrecked and its not covered under warranty. i check my coolant level regularly now and when i first heard about it the large coolant tank was below min level and the smaller tank was also down but not at a minimum level. I've looked at some other logs on here and the only difference i can see is I'm running a c-a-tless d-o-w-npi-pe, are there any settings i need to change because i also have the EWG harness connected....

I run the same set up but have spent a lot of time optimising map 6 to suit my car. I started with Map2 and FUA set to 10, seemed to work ok.

just received an email from Terry and been told to change FUA to 20 and relog map 3, so i'll see how it goes, are you running meth as well or just the d-o-w-n-p-i-p-e?

haha i see what you mean, just been looking at your logs and its crazy how much lower your intake temps are compared to mine, I've got the standard airbox with just a drop in k&n, removed the slat from behind the grill and made an air scoop to directly feed into the opening. il give these new settings a go tomorrow and see what happens

some logs here, still unsure why the intake temps are so high, ambient temperature of 4 degrees celsius last night and still high, also timed the car via dragy and its nearly 2 seconds slower (100-200kmh) now than it was was i had just a tuning box

The charge cooler circuit has no level monitoring sensor. Has to be checked manually...seems daft

Kyle, start by looking at the level in the small coolant reservoir to verify if you've still got coolant in the system and top up if neccessary

Checked it last night and had to top it up, checked it again today and it was below minimum, may have a damaged rad by the looks of things. Had some feedback from the logs saying the fuel trims are maxed and timing is really bad so im going to try map 2 once ive checked the issue with high IAT
