Testing the modified files now - so far so good (modified 0pa bench flashed just fine), but actually I have some concerns on the calibration (0da).

While most of the settings from a 530i are going to be useful to copy to a 328i, I think there are many differences in parameters between an E60 and E9x that we need to make sure are taken into account. AFAIK - and Terra, correct me if I'm wrong - you only changed the power class on the MSV80 "330i" 0da - but there are several other parameters that should stay as the "328i" settings such as the chassis type, battery setup, etc.

Basically, the only settings we really want to copy are the same ones that differ between a 330i and a 328i - valvetronic settings, DISA, VANOS, ignition, torque limiters, fuel, relative filling, and possibly cooling (330i seems to run the pump more aggressively, at least compared to the 325i).

I only have about 1/3 of the parameters mapped out currently - and many of the constants are very difficult due to differences in layout between MSV80 and MSV70. But it may still be enough to copy over the things that I know are important for a "330i" version of MSV80, without messing up the things that are specific to an E9x.

Basically what I'm saying is, the proof of concept is there - but it probably needs a bit more work. However, in the end - it looks like the days of "black box" tuning for the 328i are over.

Well that saves a lot of work for you! I can only imagine how many times you had to get into where the DME is.

Just let me know, I'll work on getting a base dyno done soon.

When are you doing a baseline? Carb Connection in Kirkland isn't that far from you - if you can make a trip during the week, maybe I could meet you there.

I just flashed the modified 0da that Terra made. It works on the bench just fine - but I think I'd want to verify the parameters first.

The biggest thing is you don't need a $500 flash tool for this. The laptop I use for flashing literally cost me $20, the dcan cable wasn't much more.. I don't have the modified one like Terra does yet, but I'm sure it's better/safer.

I'll call them tomorrow and ask them if they can do it during the week. I'm sure they can.

What I've done was compare the 530i and 528i tunes, and applied those differences to the 328i and 128i tunes. The idea being anything that stays the same between the 528 and 530 are chassis specific, and anything that changes is engine specific. While that logic might not be 100% correct, I think it should preserve the important chassis settings and copy over the important engine settings.

OK, that seems reasonable - I think I can check it easily enough. While I'm not confident that many of the logical constants were really found correctly by the search routine (in fact most seem inaccurate), they're easy enough to find in the disassembly and I have most of the important ones anyway.

Is the Powerclass value the same for the 528 and 530?

528 is 01, 530 is 02

[hassmaschine]

we can do it all over OBD now using WinKFP.

[Dan Bilzerian]

So I called in, they said they want $150 for a baseline then if you can flash the car while I'm still on the dyno they wont charge me for a second dyno but they will charge me $125/h for the tuning regardless of who tunes it hahah.

The guy who runs the dyno was on lunch so hes going to give me a call back to see if they have time.

The guy was super cool, he said as long as I don't spend 30 minutes or more on the dyno then he won't charge me the extra $125

[hassmaschine]

yeah I don't get why they're so spendy. ouch. I guess cause there's really not that many dyno's in this area. Used to be one up here in the 'Ham but I think the guy died a few years ago and his shop is gone.

Yeah I guess it's not too bad if it'll be under 30 min you think. He said they have wide open availability next week. I have a second interview Monday and then I'd be training Tuesday and Wednesday. Does Thursday or Friday work for you?

[hassmaschine]

I could probably do Thursday.

Wouldn't mind doing a baseline on Thursday while I'm there. Maybe he'll give us 2 for 1.

Let's hope that's the case! Do you have a time in mind?

[hassmaschine]

first thing in the morning would be best; I can flex my work hours but I need to be here in the afternoon.

Sounds good! They open at 9am I'll call and see if I can schedule it then and I'll just shoot you a text confirming.

[Terraphantm]

Maybe you guys should just flash the RSA delete before strapping the car down just to make sure you avoid the $125/hr. Switching parameter flashes would take < 5 minutes.

[hassmaschine]

yeah good idea. And start with a stock 328i 0da.

I don't know what RSA stands for but I'm all about saving money lol

Maybe we should start an MSV80 thread...

I've got an '09 328i w/ 3IM and stock ECU if you're still looking for test subjects
