my F22 turbo project

k..sounds good. I got a mechanical boost gauge, and while I don't have boost yet, it will still measure vacuum. also, how do I straighten the stupid plastic hose that came with the gauge? where can I route it?

well, i guess knowing that I don't need the pump, it's another thing I can hold off on, I will get it later..but, once I do get it in, will I need to change any settings, like with the safc, or what? Also, what fprshould I get? I found a b&m one at area 51 for 65 bucks..not sure if it comes with a gauge or not. Also, how do I keep the map sensor from seeing that there is boost? since, it doesn't know what to do when there is boost present, ya know?

you dont need a new FPR either...unless you want one of course. The map sensor is taken care of by the AFC. Its a fairly complicated concept...but basicly the AFC intercepts the map sensor voltage and raises (or lowers?, i forget) it according to the settings the AFC has. when the voltage changes, the ECU uses a different point on the fuel map and sends more fuel because it THINKS the vaccume is in a different spot than it really is.

when the map sensor senses boost, the AFC interupts, and changes the voltage to trick the ECU into thinking there is no positive pressure....i know thats a horrible explination sorry lol

there is a better explination on the "engine management FAQ" on www.homemadeturbo.com

i never straightened mine out. its not a big deal. but you can run it through the firewall just like any audio wires...the make sure there are no kinks in it

[Swifty1638]

saweet! so, wut happens when the map sensor detects fuel, and the afc doesn't do anything for it? My friend had made some contraption for his boosted h22, and so I dunno if i'd hafta do the same..thats more money I am saving..also, how much psi are you running, and how do you set it?

got that pic yet? I THINK I know the alien thing y u are talkin about, but I am not 100% sure..

also, how am I supposed to use a t fitting to fit the thine white stiff hose the gauge came with? I think I need a pic of the t-fitting looks like? There are MANY different kinds out there..

*sorry if i missed this somewhere*

but may i ask how much all this ran you? i'm thinkin about a turbo and your pics FINALLY let me figure how a turbo works....

swifty - ill have a pic by tommorow, sorry for the delay.

i.c. - Iv spent about $1200 on the setup all together, every little thing included. and thats with having to buy 2 intercoolers lol



On another note, i mentioned it in MRXs tunning thread but i might as well mention it here too. My car is officially run by uberdata. MRXs map works great on the DSM setup, a little rich but thats because of his crazy T3/T4 CFMs so when i borrow my buddies wideband i can tune it to my car specificly.

only problem with the map that i have found is the Vaccume problem. F22s when in full vaccume produce upwards of -25 in/hg of vaccume, where i guess most civics stop before 24 in/hg so at that low vaccume it becomes very lean. I tried to play with the map scalars the other night in uberdata but like MRX i didnt get very far, there weird to modify. i think im gonna post up a thread on the uberdata support forum and see what those guys say about it.

hey accordr33 if i use civic 93-95 sohc vtec injector seals for the 450cc would it work and fit? aite thanks

[Accord R33]

um...why not just use the seals that are on your accord right now? they fit fine if you drill the centers out. i have no idea if the civic ones will fit or not. i guess they would but i dont know for sure.

if you dremel out the inside of the accord ones they will fit, but you will also have to drill the insides of the civic ones out too

hey Accord r33 and midnite....

how many degrees do i have to retard timing per boost (10psi)
or.....will the uberdata handle that, or do i have to still manually do it with the distributor...thanks.

[Accord R33]

you have to tell uberdata to retard the timming. i think the map im using which is midnite's has it set to .9 degrees per lb of boost which is pretty conservative.

[theone]

SWEET!!!

i shall have the same...

thanks man, one less thing to worry about

hey theo whats with the rake in that pic in your sig?
