I am getting ready to do the hack on a little budget project i have and want to see if anybody could tell me if i am going in the right direction...

Also, what corrects the load factor when using the hack?? As far as sometimes i can be at 4000 rpm's at 1psi or at wot it could be at 9psi?? What determines that it dosent go rich as hell at 4000 all the time??

Anyways, Here's my plans dsm 450's, S-afc, map 6 in 14 out, stock base fuel pressure, all on a z6 with 9psi??

BTW, I have searched alot, But every single thread has been so cluttered up!! It sucks....

Thanks in advance

 

what does the map 6 in 14 out do? make it to where u dont have to set the afc to -40?

 

From my understanding, It converts the honda map sensor voltages close to that of a GM 3 bar which is roughly half... Letting you zero out the afc at idle and so on??

 

it would be 14 in and 6 out, also the stock map is good to around 11 psi. and as far as the load factor you cant realy tune for partial throttle well with the vafc. its basicaly good foro WOT tuning and thats it.

i thought its 6in, 6 out

 

okay nooob question.

What exactly is this AFC hack everyone is talking about and what does it do?

for the stock map sensor it is 6 in 6 out

variablevalve: dick answer = SEARCH, nice guy answer = it is a method of tricking the stock honda ECU to idle and run using ~450cc injectors which also supplies the necessary fuel under boost conditions up to 10 psi or so by manipulating the MAP sensor voltage output to the ECU. Search for more detailed information...

the actual MAP signal controls the fuel

if u are at 4000 rpms and only 1 psi, the ecu already has a table for a specific fuel pulse...

if 4000 and 9 psi are seen, then theres a diff fuel pulse...

thats why there is the fuel and ignition tables... so u can tune based on rpms and input

you are forgetting that the AFC deflects timing as you tune fuel, so when you are at 4000 rpm and 9psi, it is reading that you are at 4000 rpm and 10hg vacuum, or something similar. that is how it works.
