And I recently bought a Schwaben scanner. The live data is very helpful. The only question I have is, timing intervention. I noticed that even at idle it switches back and forth between active and non-active. Does that mean that a knock sensors are picking up something even at idle? I was hoping to ...

Hello again it's been a little while. Still trying to sort out my ECU. Quick update. Beginning of this year my engine finally gave. 258000 original miles 14 lb of boost. A little blow by at first, then a lot, then a ton of blue smoke out the tailpipe. I built a 3 liter M50 Stroker motor. Full ARP Ha...

I thank you guys for all your hard work I've been following this post religiously. I have definitely learned a lot. but not enough to be able to really contribute anything solid. I was able to use a lot of your knowledge to tune a couple of my friends modified na E36s and 1 low boost turbo setup. Bu...

I have been following This Thread religiously. And I'm currently in the process of building a 3 liter M50 Stroker motor for my car low compression to be used with my M122h supercharger. But in the meantime I'm experimenting with my old Engine with over 250,000 on it. Took me a little while to get th...

That would be great. Right now I only have a very basic understanding of how these systems work. I did try to add it myself and somehow screwed everything up. I decided to save my mess up. And hopefully later on compare it to what your finished product is and hopefully be able to pick out what I did...

Thanks for your help. I know it's a lot of work I've been reading a lot about how you create definition files. I'm starting to get a basic understanding of hex. But I'm still a long way from being able to write my own. The xdf you wrote for the knock sensors is very clear and simple. Perfect for som...

I have it working pretty good right now. Drivability is very smooth almost as if my car was dead stock. Wide open throttle Vanos on and off is working very well. Still having problems with the O2 feedback trimming fuel at part throttle.Hairyscreech had mentioned earlier that I would most likely have...

Back again. I figured some of it out after reading a lot more post. I did install a larger Mas and multiplied the scale by 1.4. That seems to work good. Scale is from 0 to 1222 kg/h. I'm a little hesitant about changing anything else on it. But if I have to I will. Right now I have all the fuel tabl...

I did manage to get it running better. But I must be missing something. I think some of it has to do with the injector length and voltage. I'm not sure how or if I should change it for the larger injectors. Should I lower all the values by the offset size of 60% larger.? Or only certain ones to a ce...

I am using an air-to-air intercooler. No blow off valve. There is a bypass valve built into the supercharger that reroutes boost pressure from the bottom back into the inlet of the supercharger. But that doesn't open until it hits 13 PSIG. Right or wrong after reading more on the Forum I decided to ...

I've been taking in all the great information and trying to make it work. Still having problems down near idle. I did get the voltage set up as close to perfect as possible. No accessories on and every accessory I can find to turn on bringing the voltage Down The afr's Hold Steady. It idles good. Bu...

Thanks both of you... After trying a few things I did figure out that the vanos was load related. It's running a lot better. Still having some problems pulling enough fuel at idle and low load in open loop. Lowering the fuel pressure a little did help. WOT + 27.5psia = 12.3 Afr. So that's good. PT s...

That will definitely come in handy when I upgrade to a larger Mas. Can anybody give me an example as to what the fuel Maps should look like when rescaling for much larger injectors? Especially part throttle Vanos on and Vanos off? If my math is correct these injectors are 60% larger. I lowered the c...

That did it.. now the real fun begins trying to tune for 42 lb injectors. And boost from idle to rev limit.

Lol... I went back to the 413 again. Still getting code 1211. I'm going to reset and see if it comes back. I'm not sure which bin is for my car. A lot of stuff was swapped around by the previous owner. I'm using the red label one from tunerpro. The vehicle speed signal is good. After it hit some kin...

When it comes to this type of tuning I'm not really sure of anything. All I know is my car does run with a 506 bin in my 413 DME. But since it doesn't run right maybe it doesn't work?

Okay so my stubbornness won out. I went back to the 506 rescaled and redid all the maps for the larger injectors. But it seems like some of it doesn't do anything. No matter how high or low I set the idle it still hovers around 1,000. And I have a code 1211. Self test failed. But if I unplug a senso...

Hello again. I definitely mess something up with the 506 files. I saved and upload it and the car will not start. I'm completely new to this type of tuning. So I went back to the 413 setup and at least the car runs. It doesn't run right but it runs. I think I have the whole upload download , checksu...

Thanks for your help. I did try the 416 bin and xdf. but it didn't have the maps that I needed to reschedule my injectors. So I switched over to the 506 soft and the bin that goes with it. It's running a lot better. I can't seem to get the idol to come down from 1100. And I'm getting a check engine ...

Thank you very much. That did the trick. Still have some fine-tuning to do but at least it's idling nice and smooth and is drivable again. :D hopefully I'll be able to get it back on the dyno again this week. Two weeks ago it hit 303 HP and 291 torque. On a deadstock engine with 253000 miles on it. ...

I just tried a bunch of different times to load that file. The file is in HTML format and it will not load as in xdf file. I'm still running the stock Mas for now. I have the larger 3.5 one for a 540. The stock one was maxing out with the f i c 6 at about 4000 RPMs. I rescaled and clamped the upper ...

I must be missing something? The one that says BMW 413 Red Label chip 623 xdf. It shows up as an HTML document. I tried to save it in bin definitions and I tried opening tuner Pro with it. TP opens but still no xdf file. Tried going to file location and loading it and it will not load. FYI that is t...

I did find one and I saw it before as well. But how do I convert that to an xdf file?

That's what I figured too. Unfortunately after weeks of searching I could not find a red label xdf file that would open. Any ideas where I should try?

Thanks for replying. My DME is the 413. Right now I'm using a 413 bin. And the 506 soft xdf

Hello have been having some problems and can't seem to figure this out. Car is 93 BMW 325is my original build was M90 Eaton supercharger using fic 6 piggyback. Peaked out at 9 PSI. Had it running really good but decided to work on the M122h. Was able to get that running good. But after months of try...
