What are the sizes of our stock injectors and waht size should i upgrade to? I dont want to pay for rrm's stage 2 since i can probably get injectors and a safc2 for half the price of a stg 2.

 

Good luck with SAFC... as for stock injectors they should be 210cc.

 

I thought stockers were 240cc, but safc is fine if you need help ill help you out with the settings

 

what size do you guys suggest i get to upgrade?

 

If you've got an SFC to work on the lancer you should let everyone know how and just how you install it as there has yet to be done... i take that back they have used it to take fuel out but not add... ecu just won't see it for some reason. Let us all know if you've got it going though.

As for the recommended injector size you need to give more info... like boost running, turbo size/flow, fuel management your using, and fuel system info ie pump, regulator, etc.

 

i have the rrm nonIC kit but will be getting an IC ina few months. ill run like 8 or 9 psi when i get it.

 

stock injectors are 240cc. to use safc, bump up fuel pressure or upgrade injectors and tune down. to get positive correction, run a larger MAS along with the fuel upgrades. RPW gives 300cc injectors with their turbo kit to work with an safc, but based on JVLancer's settings, i'd get 310-350cc. what were your settings again JVLancer? (just for a broad sense of what the corrections might be)

 

also, i believe by stage two, you'd have to control timing. so i guess you'd have to invest in an emanage or an outdated S-ITC. just going RRM is a no hassle solution.

 

The bad thing about adjusting the lancer in only negative using the afc is that the timing gets drastically pulled at the same time... how you ask is because the maps are interdependant. The fuel curve and timing curve operate off the same principles. If you pull fuel by adjusting the the MAS signal lower then you will make the car think it is seeing less air at that rpm. At the same time you do this you shift the MAS signal on the timing map as well. The timing will get pulled the more you go... at higher RPM's this could be as much as 15 degrees. You'll be safe but a lot slower than you should be. Just some info for you.

AFC's work to pull fuel but due to the mapping they have negative effects when used. Also the range of adjustment is very large in between settings... meaning you adjust a large RPM range with each knob. I don't know how much better the SFC are but you lose out when you do such a wide range. The RRM piggy adjusts at over 20 intervals... meaning there are over 20 points of RPM adjustment with the RRM piggy. Much more accurate this way.

pgmike... i suggest adding up the costs of doing it your way and the tuning time then compare that to the upgrade. Call RRM for specific pricing on that as your mods make differences. As Rhyzin has said its an easier package but to add to that it's also a developed one. You could possible blow you motor or damage it when tuning yourself. If your going to pay for the tuning then the price is going to go sky high. Good luck

Just remember there is a lot of help on the boards so upgrading yourself is very possible but can be frustrating and lengthy. Either way just don't rush or it'll cost you more than expected for sure.

 

i dont think i want to try and tubne it myself especially since my friend that knows that stuff is going to law school in a few months when i would be wanting to do it. rrm told me it would be 1300 to go stage 2. just a lot of money that i need to be spending on rent and other things. thanks for the info guys even tho i didnt understand it all.

 

Ill show u a few pics of the fuel curves on my afc but i reccomment talking to RC eng. and see if they can custom make you some injectors, the punched out 300cc's would work fine for 8-9 psi anything above that is pushing it, which we all know once you boost u want more and more... and like i said before about the HI and LO settings with the afc you have to let the computer do most of the work letting the computer work till 98% of the LO and HI - 99% is how I have mine set, runs perfect no glitches at all, but ill take some pics of my fuel curves so you guys get a better idea. Also keep in mind that im running 55psi on my fuel
