for those of you that haven't, you might wanna read this post dealing with afc and timing

Re:The truth about the afc hack!!!!!!!
 

Bro, I apologise. It was late at night, and I misread what you were saying.... I remember at the time thinking you stated it could be done that way, not that you were asking a question. I'm feeling pretty stupid about it right now, you did not merit the reaction you got from me.

To give general reasons why it wouldn't work, a fixed rate resistor put in series with a varying value potentiometer (the MAP sensor) will skew the signal instead of manipulating it in a linear manner. Depending on the MAP resistance, a proportionally larger or smaller than needed amount of load would be dropped across the fixed value resistor.

A capacitor is going to charge up and then maintain a steady level of voltage flow, in a DC situation. You want the ECU to be able to see the MAP voltage as it changes, not having it's response thrown off.

i jus wanted to add cuz i dont know if this was stated or not. and i remember someone askin. you dont wanna use a missing link cuz it wont let the afc do it's "hackin." and no fmu or fpr is needed. also, if anyone wants to boost higher then 11-12 psi. a 2bar or 3bar map sensor will let you do that. the honda oem map sensor usually maxes out at 12psi on most cars. sorry if i've repeated any info which has already been said.

how was ur idle b4 the hack? have u tried adjusting ur idle screw...

Re:The truth about the afc hack!!!!!!!
 

I have a quick question to ask too. Most of the guys on the board are running DSM 450cc injectors, but is it possible to use any other 450cc's such as RC? And will I be able to use the same settings as the other guys using Dsms.

Re:The truth about the afc hack!!!!!!!
 

Yep, no problem. The only thing is you won't have to use a resistor box.

Re:The truth about the afc hack!!!!!!!
 

ive spent 2 days reading the garbage in this thread. UUGGHH is the genral gearhead populations really this underinfromed ? uugghh. i was gonna wiegh on on this but i will prefer to sit back and let joseph eat you alive instead.


the issue isnt can but should you. Yes you can use the Vafc hack. Should you NO. if you cant figre out the freeware stuff get a hodnata or a Zdyne and find somebody competent to tune it for you.

I could realy dive into this Today and Joseph knows i could bury you with pages and pages and pages of S/d thoery until your eyes buged out of your heads. but bascially i wont. Dont use the stinky cheese VAFC. its like Playing a $5000 PRS guitar with a ------- sledgehammer.

Thats all i have to say.

Re:The truth about the afc hack!!!!!!!
 

And I'm going to have to disagree.
The honda ECUs do linear interpolation.
They have either a 15x17 or 20x10 VE table, which even you admit is overkill for most situations. With linear interpolation...

This site isn't about building a 9 second turbo car with the budget of a race team.
This site is about cheap, DIY solutions that work.

Unfortunately, I have to say the MAP-hacks work 10x better than a FMU, and when combined with a chipped ECU can be truly fearsome. It works, and works well.

That's all I have to say about that, I guess.

Re:The truth about the afc hack!!!!!!!
 

on the MAP hack working better then a FMU is absolutely agree. Big budget over here are nut house racing What budget were scrapping change to buy a new turbo
