Help with engine management
Ok Im making a turbo shoping list so once I get my new trans drop in I get to start this but one thing that i can't make my mind up is going with PCS XFC or The new aem FIC system. I dont want ems or kpro. My goal is may be max 15 psi for racing but i want about 7-10 psi driving on the streets. so far my list is
Garrett t3/t4 E
Dezod parts mani, inercooler, piping, and downpipe
Crower stage 2
crower valve springs and retainers
Crower rods
wiseco piston 75mm bore
wilbro 255 pump
catch can
srt-4 injectors
Tail wastegate and blow off
arp studs
FMS hg
dezod PnP head
koyo radiator
jdmfab IM
Bigger throttle body
02 wideband
oil cooler
comeptition clutch and flywheel
Boost timer
turbo controller
NX ntercooler more for show
I know that with this could lay down more power if i wanted to but i only want but 15 psi max, and I know building up the motor i will have a lot less promble down the road then if i half *** it.

Re: Help with engine management
$8000 in a motor and people want to run them on piggybacks, I'll never understand this.
Either one will require an Aux. MAP sensor, since the stocker can only read about 9.8 psi, but rather than reading off a 3 bar and doing something with it, a piggyback just screws around with the stock signals. You'll never have the control over a piggyback like you would over a stand alone. You'll have to frig around with everything to make it run right. F/IC will only allow you to pull timing out from the stock map, which in theory is all you need to do, but you'll fight with either tooth and nail to alter VTEC engagement, it'll probably end up being different in closed loop vs. open loop, and the piggyback will really only have semi-total control in open loop. In addition, any excessive or crazy alterations that you might have to make are going to **** off a stock ECU. It'll only let you adjust so far before it exceeds its own limits and shuts the party down when it thinks there's something wrong, AND it learns the tune as you go, then tries to fight back trying to trim it out. Just get it out of the equation and the whole thing works much more smoothly.
15 psi is A LOT of boost. You should be wanting complete control over everything (i.e. a standalone ECU), but whatever. No one's really played with an F/IC enough to know what exactly it can do, the PCS seems to be hit or miss as to whether its a set up and go, or a fight to make the car run.
Both the F/IC and the PCS are in the high 400's. A Kpro is around 1100 plus a K-series donor box. Basically for $700-900 more (depends on price of donor) you can be running complete control, with on board boost control w/ boost by gear (because at 15 psi 1st and second are nothing but tire warmers), a huge, completely adjustable set of maps, and all the cutoffs and protection limiters that keep the motor in one piece, not to mention the extra control = extra power. With the amount of money in the motor, it makes zero sense to run a piggyback. At least give it a fighting chance to hold up for a while

Re: Help with engine management
I hear you on the stand alone system but i wa wondering since speed foo was able to 12 psi with pcs. I was ssaying 15psi max. I would love to have Kpro but the only thing is no near by shops to buy it and tune it.The closet shop is like 700 hunder mile away. boiler I trust evrything you say, I know you know what your talking about. So what if i did this with pcs what could i reach,o that way i could save for kpro

Re: Help with engine management
I have to agree with boilermaker1 your willing to drop that much money into your engine and then you are going to half *** your fuel and engine management system your asking for problems down the road. If I was dropping that much into my motor I wouldn't want anything less than a K-pro. And donor ecu's are cheap if you keep your eye out I got mine on ebay for something like $85. lose the NX ntercooler or the pnp head and spend the money on a decent standalone system you can always save up and get the other stuff later. these engine are too fussy without it
Re: Help with engine management
the nx setup i can pick up for cheap as hell like a wholesale price i got hook ups in cali, and the pnp could wait. But like i said the only tuner is in tennase 700 mile away and i live in arkansas so try to get the car up thr for install and tune would be a bitch. the only one that could be tuner around me can do ems but i like kpro alot beter, I can get a band new ecu at honda cost my uncle works for IRL and very good friend with honda vps, that way i got my band new 2001 civic and for only 10g for an ex full loaded . I dont want to drive that far on a non tuned system. I wish i was still live in cali

Re: Help with engine management
Why are you wasting money on a motor build for only 15 psi? You won't come near enough horsepower to destroy a stock motor if you're tuned decent. I'm on 15 psi right now with a stock bottom end....

Re: Help with engine management
I think the only thing that saved me is that my head lifted enough under that much boost to blow some pressure out instead of keeping it all in the cylinders and breaking the rods.
So yes I hit 12 psi, but it was neither intentional nor safe. Don't sink all that cash into a bulletproof motor and then hamstring it with a piggyback. Don't get me wrong, I love the PCS-XFC, but I know both the car and I are going to outgrow it.
Andy, what happened to those Crower and Wiseco guts you used to have in your bottom end?
Re: Help with engine management
Thanks for the low down guy! I trust in your replys I know you know your stuff, andyman could you help me out with one more thing, when I go to kpro dealer sites they have three differant kpro so my qustion is can all kpro work with the em2 or is their a D17 kpro. speedfoos I been reading your build since day one and it was really cool to see it on the road that why I want a turbo. It sucks that I would have to tailer my car so far to get tuned, The only reason why I wanted a "bulletproof" engine is beacuse my uncle told me that if I'm going to turbo iI should build up the motor. Just so you guys dont think he know about building, He work for IRL Andgetti green team building indy cars mainly for tony kanaan and dario franchitti indy camp. If any of you fallow IRL dario is going to nascar, words for his mouth to some of the team.

Re: Help with engine management
I'm glad I was able to corrupt someone else!
This is the k-pro you want:
Hondata Link fro D17 K-pro
Your uncle is right about building the bottom end, you'll be able to run a lot more boost than 15 psi on it though if you want.
