OzBMR Can you do a virtual dyno on this log? I want to see how accurate it is (this was my log when I was dyno'd).

Couldn't see a link, but it won't work if it was done on a Dyno, the loadings are different. Has to be road runs.

Do you have a 4th gear pull with WOT from 2500 RPM?

If you flip back 10 or so pages you'll see that I posted a log after doing the BEF and was told the same thing - dangerously lean AFRs with fuel rail drops. I immediately yanked the JB4 and have been much happier ever since. I think something is wrong in the MHD/JB4 BEF instructions or coding. Is anyone running MHD/JB4 without meth that is happy with it? Has good, safe logs? Strong dyno performance?

EDIT: Which adaptions should I be resetting? All of them? Also, do you think I should look into doing anything with sparkplugs? I am using OEM and have never replaced them and I'm at 47k miles. I'm going to drive around a bit and do a couple logs and post them tonight. Last edited by baldeagleman; 02-04-2020 at 11:44 AM.. |

Install a set of new NGK 94201 plugs SILZKGR8B8S If you are still getting timing corrections after that, flash the 91 map

Your gas lacks the octane to best support that tune. Your fuel rail pressure is holding better. A few more WOT runs and it should adapt and dial itself in. I think you should flash the 91 octane map, only take a minute. You might end up with a little less power and torque but it'll be better for the engine.

Should I still go through with the ngk sparkplugs? I was also thinking about trying the 91 flash. Before I try the reflash I'm going to try the sunoco gas tomorrow when I fill up as well as a few more WOT pulls.
Btw, is there any resources out there on how to analyze logs out there and/or how did you learn this stuff? EDIT New log with the 91/95 ron tune https://datazap.me/u/dparadis21/mhd-...data=5-6-19-44 Seems like the timing isn't getting pulled anymore but the rail pressure seems to be dropping. Making about 15 less whp on this tune. Last edited by baldeagleman; 02-04-2020 at 05:32 PM.. |

An easy way to test if octane is the problem is to throw some Boostane 100 in your tank. I suggest going back to the beginning of this thread and reading through each page. You'll start to pick up what's important. For an off the shelf (OTS) tune from BM3/MHD etc the boost and air fuel ratio are all going to be OK, assuming your car is mechanically good. You want to see ignition timing for each cylinder do a nice smooth curve from 20 - 30 degrees at low load, close to 0 degrees at peak torque and then increase towards 12 - 17 degrees at redline, depending on the tune and octane of your gas. Ideally all cylinders would have the same ignition timing, you have zero timing corrections and delta for knock stays at zero. Also, if you get wheel spin, or even if DSC is active and anticipates wheel spin, you may see boost drop, throttle closure and timing being pulled.

After a flash it can take a few pulls for the car to adapt. Your fuel rail pressure should be OK, see how it goes after a few more pulls.

Could something like this indicate throttle closures?
View post on imgur.com Maybe because I didn't have TC all the way off, only sport+? |

You'll also see throttle closures, reduced boost and timing too, with wheel spin as part of TC to reduce power going to the wheels. Personally I don't look at the throttle. Assuming DSC/TC isn't intervening to reduce wheel slip you shouldn't feel throttle partial closures related to managing torque.

MHD st1-93oct-xHP st2
First MHD stage 1 logs...
https://datazap.me/u/instigatorx/log-1581110609 https://datazap.me/u/instigatorx/log-1581110769 https://datazap.me/u/instigatorx/log-1581112253 100% 93 octane (not E10). Doesn't feel that strong and my amateur eyes tell me timing is out of whack. Octane problem? |

The 16_16_07 run has really good timing (16 degrees at 6800 RPM) at 16 PSI boost, in all but cylinder 1, which tends to struggle for B58 How many miles since you flashed the car, how old are your plugs and what is the weather conditions you did the logs in (dry road etc)?

- Road was fairly dry. Rained earlier, but was long straight stretch of road and I turned DSC off (long press). Temp was around 50*. - plugs are less than 2k old and gapped to 0.025. Should I go the whole 0.022 like everyone's been talking about? - car was flashed same day and I reset adaptations before the first log. |
