I think it's here: Engine/airflow/General. Far left column under Intake Air Temperature. Map Estimation. I'm boosted and mine says 105.

I do not have that option. Editor version 4.4.4

Curiously, my MAP sensor config is set to NA-Throttle Inlet. It was set this way from the factory. Shouldn't it be "Manifold"/NA-MAP? Can anyone else confirm?

weird. I also have 4.4.4

I don't have these parameters either.

Now I don't know how reading a tune off a car really works under the hood, but it's conceivable that if an older version of HP Tuners is used, it only reads what it understands at that point, and re-reading with 4.4.4 would make it appear. My tune was definitely read and written with an older HPT version.

I just tried opening my old tunes from 2018. It looks exactly the same. I DO have the parameters.

I'm going to re-read my car again tonight with the tune that is on it and see if it shows up. Maybe it just missed it the first time I read it a month ago...

mine is set to 200kpa.

I re-read the car tonight. No change. MAP Estimation still doesn't show up for me. I guess its time to put in a ticket with HPTuners. Thanks yall!

grampa_ss · 11-13-2019, 02:09 PM

Maybe being that you and arpad _m are a 2018's and King and I are 2016's is the difference?

That may be a possibility. If any other 2017 and up owners with VCM Editor 4.4.4 could chime in with what they have available, that would be great.

I got a response from HPTuners this morning. Their response and what you have said leads me to believe that that particular parameter may not be available for 2018's. Hoping to hear an answer back from them soon.

E92a vs e92

Yeah, it's gotta be that. I checked a bunch of 2016, 2017 and 2018 ECM tunes, the 2016's have it, 2017 and 2018's are SOL.

Z0Tex · 11-15-2019, 01:05 PM

Heard back from HPTuners this morning. The MAP Estimation parameters are now available to (I assume all) E92A cars in Beta 4.5.975, now available on the HPTuners site.

I'm going to hold off changing mine though. I eliminated my Static Retard and my timing dip @5800-5900 RPM went away on 2 pulls this morning. I'll adjust MAP estimation maximum if the dip returns on future logs and report the results.

Thanks everyone!

No luck here with the latest beta (plus it's way slower and crashes on exit, so I wouldn't recommend it in general anyway).
