It's been over a month since I drove the 325. I actually forgot how it felt. but now I think the thoughts I had initially that I felt not much difference between the two is may be due to poor initial response.

may be I will just bite the bullet and budget AA tune fir next month before my track day.

The website says $499 for MS45 DME? Am I looking at something wrong? Btw how good is the tune?

The tune is great. I needed it for my headers with no cats for the check engine light and the 7k redline is nice to have. Your correct, $499....

Re: 325ci ECU with ZHP engine

I have an issue going downhill with cruise control on! My car kinda burps very time the elevation on road changes to downhill. There is a small hesitation !

What could be the cause? I got a ses light while coming to work this morning. Could these both be related? Car feels smooth otherwise..

I will find out the reason for ses 1s I am done with work.

Re: 325ci ECU with ZHP engine

Ok the ses light was because the system was running lean on bank 1&2.. this problem has happened after around 25miles after adaptation reset. I cleared the codes and drove back from work to home and I got the codes back after 25 miles. So is there something actually wrong? Or is it coz of the adaptation reset?

Only problem that I see is o2 sensors or dirty maf sensor. The intake boots are brand new. Maf sensor work coz unplugging it gives me Maf related codes. Can it be DISA?

Is there a way to use inpa to pin point the cause?

I just suddenly realized this morning,

when I got the engine from the junk yard it had this Part #18101740207, vacuum canister. I found it was for some fancy exhaust flap thingy. did ZHP have this feature? Is my engine actually from a ZHP?

Regarding the Air-leak I did delete the part and disconnected the hose from intake manifold but I dont remember plugging the outlet on the manifold. Even though I might have plugged it, I just dont remember If I did that. I hopefully think that I haven't and that is the problem for lean codes. I need to remove the cabin filter inorder to have access and still its a tight spot.

I did exactly the same thing except that I replaced with a regular 330 engine. So I went ahead and reflashed with 330 zusb. Haven't tested yet but expecting some performance boost.

Quick questions, gentlemen:

1. Does this procedure reflash all control modules all at once, to the latest daten files? Or did I only got the DME up to date?

2. Is there a way to remove 6500 rev limiter? I hope to raise it to 7k.

Thanks!

ZHPs did not have the exhaust flap

i'm glad you followed my tip and found what you found. If your engine has that, then highly doubt its a ZHP engine as the ZHP engine did not have the flap as Terra said

why not just flash it to a regular 330 tune. I heard from someone that there is no specific zhp dme tune when comparing the same make/model/year/dme version from a zhp 330 and a regular 330.

You heard wrong. The changes are not huge, but they are there

A 330 swap is still an improvement man.

True No complaints on that part but I drove 600 miles up&down because I wanted a ZHP engine.!

Now that I know its 99.9% normal M54B30 should i flash normal 330 software ? If I should can you help me with the latest ZUSB #? Right now, I have absolutely no issues with the car with ZHP 7561520 software.

I am planning on catless headers so is there an Euro2 tune for Ms45.1? If there is, ZUSB# for that too please!

Thanks

I thought you had MS43 ECU? You should have flashed with normal 330 tune instead of ZHP. I don't think the ZHP tune which was designed for MS45.1 module would actually work on MS43, and didn't dare to risk my own ECU. If that's how you tested and turned out to be ok, I'm surprised and glad to know.

FYI. Use "7571613" for normal 330.

Originally mine was a 2005 325ci, so I always had a Ms45.1 DME, reason for flashing zhp tune was because I believed the engine was infact a zhp, but now it seems not

7571613 for ms43 or ms45.1?

That's for MS43. I do not know a MS45 tune for normal 330. I guess you can stay with ZHP. I don't think there's a whole lot of difference. Probably just the fuel mapping for hotter cams and higher rev limit.

BTW have you tested your max rpm with the ZHP tune? Does it go up to 6920?

It does rev past 6500, about little less than 7000 but never got a digital reading out of the exact rev limit.. Also I thought it is 6800 not 6920?
