MAP not showing any value

Post by Snake____1 »

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.

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 :roll: So I would like to try 2bars at another date :mrgreen:

Maybe you should add a customizeable maximum MAP value? :D

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

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?
