Logs check MHD

[pablom2c]

Hi,

Please check out my logs and see if everything looks good?

https://datazap.me/u/dieguitov/mhd-s...og=0&data=3-21


Running MHD Stage 1+ ACN91 with VRSF chargepipe and intercooler.

I live at very high altitude 8200 feet / 2500 meters, and gas is bad quality.

Downpipes are coming and will be installing stage 2+ so I want to make sure everything is fine. Car runs super smooth, zero problems.

Thanks.

I believe there's something that should be fixed with the altitude correction,,, it should bring the fuel/air model back in line so the stft's aren't pulling so much fuel.

But so long as stft's don't flatline you really aren't in bad shape.

I think it's safe to try stage 2+ and datalog. You'll want to just keep an eye on the STFT. You don't want them to really exceed too much past 20. Everything else looked OK.

Great thanks a lot guys for checking my logs, I will log again once I have stage 2+ installed with the downpipes.

Is there anything I can do regarding stft?

Honestly I'd address the STFT issues before flashing for more power. All more boost/power is going to do is stress that adapter more and might be enough to flatline them and risk running lean.

I don't have a running car I can look at but, I thought there was something for high altitude in the user options, or flash options, I don't recall the wording of it. The section of the flash where you can pick the coolant target, 3.5/4 bar map, etc. I think it was near the bottom there was a high altitude checkbox. Click that and grab another log. See if it does anything.

OK thanks I will see if there's a high altitude option, but from memory I don't recall it being there. Would a custom tune help with this? Could it be due to the exhaust burble? Also I have never changed the injectors in my car could that be causing it? I'm not sure which version are on my car since I bought it used with 30,000 km around 5 years ago.

No burble won't affect it.
A custom tune would, but see if that check box is there first.
It should not be something with injectors, it'd be odd for all of them to be the same if bad. If/when an injector goes bad it's most often only 1, or a bank.

I think I found where my altitude confusion comes from:

So a custom tune may be the best option here.

I have now installed the downpipes along with MHD stage 2+ 7.1, these are the new logs if you can please check them:

Right now I'm running the ACN91 maps because the gas is supposed to be 91 octane in my country, I'm also using Liqui Moly Octane Booster, do you think I could try the regular 91 OCT map? I don't know if you can tell that from the logs, or if the gas is really bad already?

Thanks a lot!

I'm not seeing much of any difference ...
