So that means depending on what gear you are in 260% can mean 23psi or 18 psi depending on conditions, such as airflow maf is seeing, and temperature changes and gear you are in?

 

So how the hell do you determine what cell block you are sitting in? There is no way because too many conditions then?

 

ic see what you are saying tae.

again, like my first post said it is an in terms of psi vs load it is an approximation to help people understand whats going on.

I have a good idea on how to determine for sure whats going on with the load, on monday ill hook up my datalogging equipment and try to figure it out.

 

the load percent correlates to MAF freq + whatever correction factors the ecu puts in due to other sensors.

Unfortunately our human minds think in terms of boost, and that's why my chart was divided in that manner. It may not be 100% accurate, but it is close enough to give an understanding of what's going on to enable you to tune the car.

 

All I can contribute to the load question is that with Mercedes it is a calculated figure that has something to do with manifold presure,air flow, rpm and throttle position. It can be veiwed in actual values so mitsu may very well allow it to be veiwed in theirs. the engine even at idle has some load on it and it can be surprisingly high.
a small amount of pedal travel has a large effect on load, for eg. 50% load isnt 50% throttle its closer to 1/8 on a naturaly aspirated engine. I havent had a chance to check on a supercharged or turbo engine yet

 

That would be great. Thanks for the response.

it also looks like pretty good reading for info on the basics of engine managment. not evo specific but take away some basic ideas

this leads me to believe that load is a air flow referance which would make sense. is it possible that the load #s are a near direct estimation of volumetric efficancy base on maf and map sensors? for eg. at the 200 % load portion of the map the calculations are estimating 4 liters of air are flowing through the engine for every 1 combustion cycle

 

Ok that is very understandable. So all you can do is guestimate and just hope your are in the right cell range for a given rpm and load point.

 

I think that if you can data log airflow and compare it to rpm you will have an idea of load and be able to know where on the map you are at.

boost level could be used I suppose at 0 bar and up as a rough estimate of load 95% and up. it will not be exact but may be reasonably close

at less than 0 bar things change and you are referancing vacuum, which could get tricky


If I am off on any thing I have said please let me know. I would rather be told I am wrong than spread false info.

 

that's my plan + a few other things

 

that will be great

 

Sorry to throw the discussion in a different direction but some of us are far beyond the stock boost limits, I push 28psi daily but with the 260% load= 23psi how can we change the entire table to higher loading

 

the 9 ecu is good cause it goes to 300% from the factory useing a larger map with more columns.
not sure if they can be rescaled. that would be nice if they can

 

I like to know as well.

 

200% load would be 2 liters per revolution. The engine only displaces 1 liter of air per revolution.
