Hi there,

Any suggestions on why the MAP value isn't showing up?

I have tried both PA0 and PA7 for comparison. @2.63v the MAP value is reading 0. On floating in a noisy 50hz enviroment MAP value bounces around 56kpa.

Just downloaded the new firmware 20180104_1855 and still no value.

please post
mapinfo
and
analoginfo
output from console

Ah, I see! But it's limited to 250kpa... What does this limitation correlate to?

250kpa is a lot of forced induction! What units do you speak?

normal atmosphere should be 100kpa give or take.

Yeah, I know. Hehe...

300kpa = 2bars of boost.

I have a 3bar MAP sensor. I might swap it out for a MPXH6400A "4bar" over time. Running 1.5bars of boost isn't to uncommon for a forged engine So I would like to try 2bars at another date

Maybe you should add a customizeable maximum MAP value?

Also note, the VE table almost looks inverted for some odd reason... Any Idea as to why?

Because certain areas were self-tuned for longer than others, while some areas were never touched? (see the green and red maps on the right)

Hi,
I take this post to ask a question.
What is the maximum pressure that rusEFI can handle?
Because I am preparing a car file for drag, and I am aiming for a maximum turbo pressure of 340 to 350kpa.
But I do not understand why I can not put values above 300kpa

No reason, will change limit to 500kpa

What is your MAP sensor maximum pressure hold ???
Model of your MAP sensor ??? PDF !!!

Hi, I have this one MPXH6400 => 400 kpa
For this race car, I will try 340 or 350 kpa

Thanks a lot...

I will try soon
Peugeot 1.6 16v with gtx3071r for dragrace.
Hop more than 450hp for the moment.
Pics & video soon

One question, I would like to know if LC & NLS work?
