Re: is thsi a good procedure, to Tune MAF transfer?
well yea. i have seen again that they are useless. but appart from that, if i had a wideband, would the procedure work?

is thsi a good procedure, to Tune MAF transfer?
hello forum. i have a real problem, finding a MAF with a given transfer function. my ecu is diy from the scratch,and my car , has no MAF (or injection for the time). i was thinking of buying a bosch MAF model, that can be found here : http://www.auto-consulting.it/DWN/Mass_Air_Flowsensor.pdf for the...

Re: determine engine load with MAP or MAF??
thanks allot for the extensive reply m8 :) i think i have figured out how to work fuel, based on MAF, and i know that the trnasfer function will need allot of tuning, since i anyway cannot find an "OEM" transfer function for any of the MAF sensors i can find... :/ i would really like if i ...

Re: determine engine load with MAP or MAF??
Additionally, your transfer curve for the MAF sensor may have non-linearities that you need to tune. ?? isin't the transfer function supposed to be factory made?? i will just take it as it is??.. (or uyoy mean that the factory function will have mistakes on some readings ? ) Use your wideband ONLY ...

Re: determine engine load with MAP or MAF??
so, here is where i am at: for the sake of my point, i will refer with RPM, to camshaft revs. with the MAF signal, and the transfer function you can have MAF = air grams / s Going into the engine. knowing the rpm of the CAMSHAFT, you know how many revs. the camshaft does per second . revs = (rpm /60...

Re: determine engine load with MAP or MAF??
believe me, i know i will anyway , have to do it trial and error way
i just look to find any info i can, before my exams are over, when i will start , to actually do things..
the project will anyway be hard, so why not take as much advice as you can...

after all, what kind of table , should i produce ??
engine load - fuel needed ??
engine load - rpm - fuel needed ??
