They have the same baseline - but with the MAF delete, theres no issue with stock manifolds because it was already tuned that way.

First time I hit this was alarming, the oil temp gauge dropped 10 degrees while I was in heavy traffic on a hot day. I had to do a little digging to learn why.

Yes, I live in Florida and it can get really warm in the summer.
yeah, KL_KFT_HK and KL_KFT_HI - by default they are 'flat' so the ambient temp doesn't affect anything. but you could make the coolant temp drop with higher ambient temps - however, I still don't think you'd always want your coolant temp to be 80c just because it's hot outside - that would be a 'track only' situation.

Would it be easier to just run a MAF tune with catless headers? I believe 6ixSpd has no issues with the base 330i tune and his headers.

Yup. No issues with the base 330i flash and headers.

Not sure if this is the same but MHD lets you pick coolant targets. The Sport mode temps seem like a good balance:

Sport Mode
• Coolant normal 95c (104c Stock)
• coolant high 90c (95c Stock)
• Coolant high+kft 80c (85c / 80c Stock) (This mode is activated at full throttle)
• Amb threshold for high mode 27c (32c Stock)
• Amb threshold for high + kft 32c (37c Stock)

Race Mode (only for drag race application)
• Coolant normal 85c (104c Stock)
• Coolant high 85c (95c Stock)
• Coolant high + kft 80c(85c / 80c Stock) (This mode is activated at full throttle)
• Amb threshold for high mode 22c (32c Stock)
• Amb threshold for high + kft 27c (37c Stock)

Yeah, but the N52 has most of the same maps.

hass did you try to change map KL_EXWMX_N (excentric angle limti..) , so it doesnt drop off after 6800, is it safe to do 180' all the way ?

did you try to tune vanos, I mean with method that worked on old ms4x cars,
first make run with vanos off to find max power, and than with vanos always on to find
max torque. then you find where curves intersect thats ideal vanos switch off point?

Hass,

I see two files, both apparently for non-maf configurations. Any insight?

Vanos is continuously variable, it's not like the older M52 cars with an on and off switch.

Hello

Sorry for potentially posting prematurely. I'm about halfway through this thread, wanting to order a spare DME to start playing with by the time I'm done reading. I'm building an n51 e92 track car, and wanting to leave the original DME alone. My question is, can I (or would there be any reason to) try and use n52 software or DME on my n51? I'm not sure if you have more tuning options available for one or the other, or if we're even capable of cloning the msv80.1 yet.

Thanks!

cloning is possible with MSV80.1 but it's not straight forward like MSV80. First of all you need to be able to recover the boot password.

as far as running MSV80 code on the N51, yeah, you could do that - but I don't think it would work too well, and you'd have to create some sort of franken tune that used the MSV80 program/boot sector along with the N51 tune.

Cloning should be the same process for both (actually marginally easier on the .1 since it already has the extra can transceiver).

Wouldn’t be difficult to run msv80 code on a .1 - pretty much identical code. Just have to change the ID byte to match the destination DME.

Right, my point was the N52 tune isn't made for the low-compression N51.

The offsets are the same anyway IIRC, so there's no reason to really do that, except maybe to make deleting the extra emissions stuff easier.

My thoughts as well. I'd love to get rid of the secondary air pump, I'm just not sure if anyone has cared enough to find the fault to disable in MSV80.1. Also not sure if any of it is worth the hassle, vs just buying a tune for MILVS and being done with it.

fault codes are easy to find - the N51 doesn't have any unique ones anyway. It's best to just modify the base tune.

yes, you need an N53 330i file with the power class changed to match your car. Otherwise, it will run in limp mode. The checksum has to be corrected but that's a separate issue, and you also need to bypass the RSA signature check.

Is anyone interesting in helping out an 328 getting flashed to a 330. I have everything I need to complete the job, but also having trouble getting the ear of those who do remote sessions to setup up the software/flash the DME over.

I understand people have busy lives, just seeing if someone could help on my final step to getting my mods finished up.

I do have bwm tools installed, though some things seems to not be working. I will trouble shoot that this evening. Then i just need the flash done. As I've' never done it I'm shy.

Thanks in advance
