hopefully this thread will become a point of usefull info.

I have some question that i would like to here from People that have turboed their lancer. 4g94

1. What are you using to monitor your Air Fuel Mix?

2. What are you using to mod your Air Fuel?

3. Are you using a Wideband 02 sensor?

4. What Rate RFPR are you using? like 12 to 1 or 9 to 1

5. Did you have to use Larger Injectors or are stock ones good?

6. Do you use a fuel pressure guage and what pressure should a turbo lancer be running?

7. Did you have to replace the lancer Fuel Pump? If so what are you using now?

Please i beg you not to start the RRM Kit pushing or Bashing please lets keep the info clean

 

i SUPPOSE you could use an AFR gauge to monitor, a wideband O2 is the sure fire way to see if your leaning out or what, i recommend wideband o2 and many others would too, larger injectors and fuel pump necessary, i went out and bought like a $35 fuel pressure gauge that you splice into your fuel line (its the top hose on the right side, vague i know, but you should know), its at 40 on idle, and i THINK it should go to 80 in boost, im not 100% sure about that

 

ok so if you use a A/F guage or wideband then how do you make corrections?

 

um, well, an AFR or wideband is only going to be telling you if you run lean or rich, if you know your kit is supposed to run you rich (RRMs), and your running lean, you know that there is a problem, so you should run through your spark plugs, and entire fuel system to make sure everything is 100%, also any connections really, check for boost leaks, exhaust leaks, if you know your system is running 100% and your doing a custom setup, your going to HAVE to get a standalone or piggyback and get it tuned

 

1. i am using a wide band 02 to monitor ratio
2. i am using a vortech fmu, aem fuel pressure reg, and safc on my car (doesnt do anything though)
3. yes im using an fjo wide band o2
4. 12:1
5. stock injectors
6. auto meter fuel pressure gauge @ 45 psi
7. 190 liter/hr fuel pump but will be upgrading again to 255l/hr

 

well i am not turbocharged yet even after my accident today i still plan on visiting my bro this summer to get spoolin'

anyways...rhyzin has the 2g DSM turbo fuel pump in his car, u can send ur fuel injectors to a company, and they can port them out to 300cc.

i've heard s-afc doesnt work and does work..so i won't comment on that.

some people say tuning a standalone is like training ur dog to use the toilet, wipe off the seat, put down the seat and make dinner, lol.

im full fleged for going custom...its WAY cheaper, and im sure u can get the same kind of gains. especially if u know someone that can do custom piping for u for free and u can get a turbo/fuel pump for free ..not that i know anybody

i think i may of answered some of ur questions, im also trying to gather as much info before this summer so i can do it all right...the 1st time

OH AND RULE #1!!!! ==== You can BOOST as HIGH as you WANT!! AS LONG AS YOU CAN SUPPLY THE FUEL RIPPMODS supercharger is boosting SAFELY on the stock internals at 11psi..whether thats the same as for a turbo i would assume it is...and RIPPMODS knows there stuff...so as long as you can supply the fuel, u can boost a LOT! but there is a point lol

 

I agree, those little blinky AFR gauges will only read out volts sent from the O2 sensor, but it can read the same light for a lean but safe condition, or a unsafe lean condition.

 

true to a point, dont forget rippmods uses a water/methanol injection system

as for TURBO, the highest a maual lancer can boost is 9 psi on stock internals, any higher and you will have a problems

 

ahh! I wanna get one for me! dont got cash!

 

ok gokusupersaiyen if the safc doesn't work how do you tune your fuel.

 

if u take your car to a dyno or u use a wb02 sensor, u can sit in idle, and change your settings on the afc and u will watch the afr levels drop or rise according to which settings your changing... so explain how that doesnt work.. its obviously doing something ??

 

Jvlancer so the afc does work and do you use a wideband 02 or just a AF meter

 

i have both.. but af gauge sux unless u spend the 250 and get a greddy af gauge.. which imho is not worth it specially if you have an o2
but the o2 is only used for tuning purposes, it just creates a log and tells you where your running lean/rich at every gear/rpm

 

safc only works to adjust your idle, it wont pull your settings when you get into boost, so its good if you want to smooth out your idle

like i said, only way to fully adjust your settings is a piggyback, standalone, or reflash (good luck finding someone to write out a lancer map)

 

a supercharger runs 11psi because it doesn't get its air heated up from being connected to the exhaust like a turbo does. the water/methanol injection also contributes to raising boost. a turbo is limited to 9psi due to heat, which causes predetonation.

safc works best with upgraded injectors and may do very little with stock injectors. turbo upgrade requires a new pump and boost sensitive fuel pressure regulator. a possible alternative is pump, afc, and very large injectors though i have my doubts about the ecu trying to compensate large injectors. vortech fmu with stock injectors and upgraded fuel pump can be used in place of a safc.

a wideband with datalogging should be used to tune. a wideband o2 with gauge should be required for FI apps boosting high psi for safety reasons.
