looking for a map that could help me start tuning to the 20-24 psi range..... doing a stupid crazy build right now and about to do some exparamenting with some parts to hopefully break some new ground for us msp ladies and gents. litlle bit of mazda here, a dash of dsm there, with some crazy madman machists thrown in...... sound like a date for my msp!!!!!!
I believe the map sensor in the AFC is only good for 16psi?
He could have one of those AFCs that you can only tune "in boost" - I believe Ken was offering those some time ago. Either way, at those boost levels he's going to need much larger injectors and therefore need to be able to tune in idle conditions which that version of the AFC wouldn't allow.
Hate to break it to you but you're going to need more than the AFC to run 20+ psi. Oh yeah, and we already have members pushing the 30+ psu range (and they aren't using AFCs).

actually about to buy the new 21 psi unit from ken... going to try to make us some coil options avalible as well do the the lack there of... hopefully high boost, lots of power, and still keeping it 9.0-1 on the compression... wish me luck ken! o and thanks for talking with me ken. you helped alot of my issues i was battling with out for the build. hope you dont mind me calling more to talk at a later date! lol

I think he means they are prob. using stand-alones, but i dono
Yes, all the big-power guys are using either a Microtech of Haltech (F10X, E6X or E8) full standlone. So you're going to get one of the "boost" only AFCs? So what are you going to do when you throw in those massive 565+ cc injectors? You won't be able to tune the idle with the AFC because you won't have that control. Are you just going to deal with an overly rich and possibly stuttering idle? As far as coil packs go the stocks are fine for just about anything you could throw at them. We hav/have had guys above the 300 whp range still using the stock coils and wires with no problems whatsoever.
Don't get me wrong, I applaud your enthusiasm but you should probably start doing a little more research before you jump right on it.
BTW, what's with people asking for perfect AFC maps for there car here? I hate to break it to everyone but no tune made for someone else's car is going to be perfect for yours, even with the same mods. All cars will behave differently. My advice to everyone is to start with the supermap that comes loaded with the AFC and work on that from there.

565's idle fine.....
But for 20+ psi you're going to need more than 565 cc injectors and IIRC there are none larger that are direct drop in or compatably with the stock ECU.

i dont think so. if kicker ran 17 psi on the gt28rs with 440's i dont see you needing bigger then 565's to go over 20 psi. O and azian6r(sp) was at 15 psi on the 30r 15psi and he was rich in the 10's with 565's.
Go check out Sam's injector-sizing formula. All I know is that at 10 psi and I am close to full duty cycle with the stock injectors. shane02p5 or whatever also has some good information on injector sizing as he too ran into duty cycle issues with larger injectors and high boost.

ehh dont really need to look at a injector sizing chart when there some one running the same size turbo i am with more boost and smaller injectors. O and btw miguels only using 760cc injectors on that 35r at 30psi and he can still make it dip down in the 10's if he wants. So 20psi depending on the turbo size will be fine with 565cc's

So he can still run rich but what are his duty cycles on the injectors? I bet he's damned close to maxxing them out. Running at a constant high duty cycle is not good. If/when I build my motor and get a larger turbo I'll probably be using 565s but only pushing 15 psi or so.

565's can be run a bit over 20 psi and not be over 80% duty if you know how to do it right and tune... big thing is being able to tune!!!!!!!!! so by saying i have to run over 565 isnt true. we have new tech now.... and saying my coils will be fine... yeah if i had 8.5-1 or 8.0-1 pistons! i am running 9.0-1 pistons. did my research and talked to alot of guys including ken from protegegarage.com and he said... actually ask him yourself! spark will blow its self out!!!! wasnt looking for a perfect map either was just seeing if anyone might have one to start me out or any pointers on one for higher boost! read before you post!!!!!
There are lots of differing opinions so whatever. Have your fun speculating but when you make big power with the AFC and 565s then you can brag. I'm not saying I know everything, but I've been here a while and there's a pretty standard formula for making power with a Protege. Why do you want 9:1 compression anyway? You're going to have to run race fuel to keep that from detonating at 20 psi.

there nothing wrong with 9.1 compression you dont need to drop down your compression when you can make more power with less boost then you can with lower compression. You also sacrifice some spool time with lower compresison too. Im not just talking out of my ass either ive talked sam who hates his 8.5's and Avarela86 who said he definetly noticed some more lag when he switched to 8.5 compression. Me personally i went with stock compression with a thicker head gasket to put me around 8.8

Very good choice. What thickness headgasket are you using?
