    Put my original timing map before I started pulling it out with 1.1 fuel scalar on E25 and not a single timing drop. Now to add more timing and boost! I'll start by getting it running nice on 14psi...

    3 (bank 1) are brand new. The other 3 are original to my knowledge (car is 12/2008 manufacture). 85,000km (53,000 miles)
  3. I've pulled timing to the point that the timing...

    I've pulled timing to the point that the timing drops are very rare. The downside is that the car barely feels faster than stock. I've still got 80L of straight Ethanol from my Nissan S15 which i...

    I suspected so. Just never had a Cobb to check. BMS back end is also identical.

    Traction control was completely off.

    I have improved the frequency and severity of the timing drops a little by making it richer down low and pulling a little timing out up high. Also I increased...
  7. Good fuel, VERY conservative tune, yet timing drops

    Hi,

    I thought I'd do a log for the first time with my very conservative flash tune. I run the JB4 on Map 1 with option 4-3 enabled, all CPS (except 7000 for 6cyl logging) zeroed and open loop fuel...

    I had the same issue. Try without changing torque monitor ceiling. Worked for me.

    I believe it's the later model valve body that you need to fit to the transmission for it to work.

    They upgrade earlier MSD80 to MSD81. If you already have an MSD81, it's just a flash.

    But we do need ISTA to list which ZB number to use for which car. Hopefully we can take it from there with WinKFP after that.

    Indeed we do. Anybody?

    I suspect that ISTA can look up the ZB numbers for use with a certain Production code and option combo but ISTA will not let you flash the Performance Pack file without some...

    Has anybody got access to BMW ISTA software to look up ZB numbers for various production codes in a similar way to what TerraPhantm did here:

  15. BMW Performance Power Kit software. How is it installed?

    Does anybody either work for a BMW dealer or know someone who does who can shed light on how the PPK software is installed?

    My suspicion is that it's simply a different ZB number readily available...

    A higher WGDC will cause a boost spike, being more likely for a timing drop to occur.

    Looks like the Differential component of the boost control doing it's job properly. Your boost curve looks great. You would probably get a boost spike without the WGDC dropping like it is now.

    Is it actually not acheiving the requested boost in the area between the 3psi and full boost? If it is, then I wouldn't see that as a problem. An open wastegate when you are not requesting boost...
  19. Yeah I might drop timing a little where EGR has...

    Yeah I might drop timing a little where EGR has been reduced. Going leaner than 14.7:1 reduces flame speed, requiring more timing so I'll prob start by returning timing to stock values where the EGR...

    Now I'm not so sure. Initially I did get misfire with a code but only once. It hasn't misfired with a code since but tip-in is still very 'jerky'. It could be sudden timing pulls. I'll log some...

    The spreadsheet has fixed colour scaling so you can see the changes you make in colour without Excel 're-adjusting' the red colour with the automatic scaling.

    I changed my mind again lol. I took a little more EGR out (again, only a tiny bit), changed the fuel scalar to 1.01 and left the AFR table because there should be no problem with 15.5:1. I think I'm...

    The goal is to add unused air by running leaner and moving slightly up in load to achieve the same torque. I'm hoping that there will be more unused air added than the EGR gas taken away so economy...

    Wow that's a very crappy factory r/s ratio. With good strong pistons, pins and rods, the pins could safely be downsized to 21mm and pin height reduced to around 25mm. That'd allow for a considerably...
