I resolved partially that problem transitioning all my parameters to new file in tunerpro And noticed that if shift time too short -PCM itself...

well i compared your tune to another tune and someone has adjusted things within your tune. Now what does that mean? Until you start...

Great information, I had no idea and this makes sense. Curious to dig in and see. I am sure your connection protocol also influences this. Bluetooth...

well, assuming this is a e37 PCM.... you can disable VVT. sounds like youre in the same boat as this guy.......

uploading tune attempt

Great information here, was just coming in to wonder out loud why I could read and write a gas PCM, but not a diesel. I will give this a try with my...

In comparing the stock to your current tune... This section is zero'd out in the OEM tune. I would start there (returning it to stock). I...

I'm not sure how much help you are going to find for this Frankenstein. Without a wiring diagram of everything, we can't tell what is controlling...

In the data log you can see that timing drops as low as 8 degrees at 3000rpm where I am commanding 17. That's the whole problem. I have used this...

After reviewing your log you seem to have some sort of electrical gremlin. Your Pratio just drops off and your fuel system goes into an unknown...

Where are you physically located, I have a dyno in Annapolis, MD. I'd like to see a data log of the vehicle and see what is really going on.

I'm also confused on what the ask is here.

I don't think you'd be able to feel 2ish degrees that it varies. The timing is so low on what looks to be a NA car i'd bet that is what is making...

thanks for looking, can't get a log right now in this state. what paramters are you basing that off of?

i have the same issue, its happening most on decel , in manual mode it will happens every time that you decel on a gear for a few seconds. the dtc...

Another user here running an M4 Mac 16" MBP, latest version of Parallels Desktop and Windows 11 ARM. VCM Editor and VCM Scanner seem to work...

looks like your boost might be unlimited. would need a log of main parameters to know for sure

I thought ChatGPT would be good for this stuff until I asked it to do some simple math calculations (calculating vehicle speed based on gear...

RRt, can you pass over a diag log so i can pull the proper cannels, or a list and i can get them added? also any pedal input request (my inputs) for...

I should be able run it that long on that stand, given it will idle. Have not had a chance to get back to the garage yet and test out your...

Ah, that does make sense, mostly. If idle is controlled by MAF, VVE calculations at this point serve no purpose? Will hooking up my wideband be of...

Do you mean you think the data log is actually causing the commanded timing to fluctuate or just a visual error? I can confirm by my dyno that the...

I doubt anyone will tune the car for you, but start your own work and post it here, I can offer suggestions

I suspect this is a scanner bug and prehaps that channel is polling too fast. I think it would be a good idea to remove all burst knock just in...

thank you, this is good info

When I swapped the cam I added alot of timing at WOT but didnt raise the MBT table. I raised it this morning to match my max timing and it shifted...
