anyone that tunes would be willing to help me a bit? i have hp tuners on me and would like for someone to show me a bit of how to use it. like scaling the maf sensor for the afr and lil stuff like that for a start. if anyone willing to do so pm me thanks

 

get a couple of books by a guy named Banish on amazon called "engine management" and "fuel injection systems"

 

will look into that thx

 

what are you scaling the maf sensor for?

 

cuz i just got a base tune on my car and it needs some of that done for the afr and what not

 

lol, do you have a wideband?

 

yes car is rich as hell

 

do you have standard or pro?

 

pro...

 

I would set up a histogram to read Actual Lambda / Target Lambda to get a percent, you would then multiply this in your airflow vs Frequency table.

On the axis of your histo, Set the y axis as airflow and the x as frequency, and set the plot value as Actual/Target

 

i guessing this is wiring the wideband to the lil green box that goes into the hpt box?

 

not sure on that, I only have standard

 

is this all set up on the config that can be seen? or what

 

you would have to set it up.

 

um lol ill start looking into that

 

you need to run the 5V reference wire out of the wideband to the green box.

 

ok though so.. thx for clarifying

 

you should read the manual/sign up on hptuners forum

 

what kind of wideband do you have?

 

aem..

 

did you get a decent config file yet? There is a really good maf tuning guide on the redline forums under the tuning section.
