We can hit the NGP dyno on the same day once you get yours sorted and we get a few revisions of this map. We'll be able to compare the TTE460 vs Pure 500 on the same map, and different maps on the same car. |

However - I can get it to work on my street runs, and when I have it set up properly, the results were actually spot on with what the dyno was reading. When I changed my inlet and intake, I was able to overlay my prior results to see the actual gains at higher RPM. Leave road and weight are key to the measurements. For me, this is just a fun exercise in the car off season.

The new map has less load than the previous 494whp one, less timing. Running "OTS lean" over 13.0AFR To simplify things, for a small turbo of ours, every 1psi ≈ 5-10whp. 13.5-15.5peak timing. To get a rough picture. Yes, Halim can lean your previous map out by running richer AFR, making your injectors and HPFP less stressful, but it also sacrifices cooling. I'd say keep your lower-power one for tracking. Last edited by ericlr1225; 03-13-2024 at 11:06 AM.. |

I am not sure tbh. 215-220% to me is right above 500whp on my car.
My Stock turbo MM stage2+ E30 map has 190%, assume it's making 440whp. Peak power is between 5500-5800rpm for popular tuning strategy. Big turbo may see peak later. I think we can get a rough idea by scaling it, but again, it's just a rough guess. |

Load won't lie. I was running v1.2 MM stage2+, it's detuned from v1.1, less boost so probably 410-420whp. Since whp moves with rpm range, we don't know where is the peak power. I was assuming 5500-6000rpm. It won't be accurate. Last edited by ericlr1225; 03-13-2024 at 11:02 AM.. |

Keep in mind I have a custom tune with cam angle/timing changes, I have MILV rockers that increase valve lift and I'm using a HPFP. I'm probably just going to hit the dyno sometime soon and test all of these revisions to see what works in real time.

Halim doesn't want to push further on my setup. If my fueling situation was a bit more robust (currently Dorch Stg 1, stock LPFP, stock injectors), we'd add more ethanol & timing to the tune.
Not really interested in spending a couple more grand just to gain a little bit more hp from a turbo that is likely already max'ed out, or wanting to run more than E50, so will leave as is and dyno it at some point to see how it compares to the other maps. Altho, I was heading to a meeting this morning and gave it some gas around a corner. Let's just say it woke me up and it's good that I have some track skills. It's quick!

What Halim is doing isn't anything that another tuner can't do. There is a reason everyone wants to work with E85 - you can increase timing to the moon and back. That's why it's an off the shelf tune. More efficiency can be gain when it's actually tuned for your car. But if you're happy this is as far as you go. Anyhow, Excited to see what the P500 does - I'm also curious to see how my final tune will measure up to these off the shelf tunes. Of course, I don't plan on running E85 at all.

As is I have >10 maps that I can quick switch between for street and track, not to mention built in ethanol scaling within those. And, a custom tune isn’t going to fix what is likely a hardware issue on track that I need more data around first. A custom tune isn’t a holy grail thing either. It works for a particular setup and conditions at a point in time. Deviate from those much and it becomes not the ideal tune. |

Your car is at a sweet spot for the setup you have. I took an OTS MM stage2+ log this afternoon with my current setup. Halim said he could send me the MM Stage3 that you guys have, I'll do another one with it later. For reference: https://www.bootmod3.net/log?id=65f2...d7553872919237 BM3 pre-load "F10 M5" injectors table drives weird. LOL |

Take a look at these vides - the first video is Fixed cams, and the second is variable cam timing and you can already see what that a few degrees advance or retard can be worth as much as 30whp under the curve. Quote:
They have the ability to adapt as much as any tune does. It's your car and money, no one is saying you MUST do anything. But to act like this OTS tune is the best you can do is not correct.

This is for everyone else, just in case you're curious.
Here on my VD dynos comparing lift and VVT changes ONLY. Timing and boost are the same. You can clearly see that adjusting the cam phasing has an impact on the power of the car. Adding cam advance increased low (and even mid range, but there are some timing drops on this log) power, but towards the higher RPM the "standard" (still different from the stock cam angles) produced a more power until high rpm. https://f87.bimmerpost.com/forums/sh...&postcount=147 You can see the stock cam angles here https://datazap.me/u/amuroray/stage-...ata=4-23-37-39 And my Standard tune and MILV spec tune with just VVT adjustments here: https://datazap.me/u/amuroray/log-1696463639?log=0 Another thing to note - WGDC changes because of Cam timing changes. This is like arguing that the Armani suit you bought off the rack can't get any better with tailoring. Like yeah, it's a nice suit and a nice cut, but there is room for improvement.

How are you guys getting into contact with Halim?
