i have this code it is killing me my car is running like crap i think it is the intake i got off ebay not sure tho did anyone fix there problem

 

I did, but it required changing parts of the fuel map in my RRM Piggyback to do it.

 

i dont have a piggyback wish i did

 

I have an 08 Lancer GTS. I just installed my piggyback from RRM yesterday. Got the same code today which translates into bank 1 too lean. My car seems to run fine anyhow... How did RRM fix this for you? Did they reprogram the piggy or just send u the map via email and you uploaded it?

 

I started getting the code, p0171 when travelling to work back and forth but there is no problem since no Limp mode is on. I read all the post, cleaned my MAF, check the O-ring, loof for vaccum leaks and even the gas tank cap tighten....

I got my home made CAI, no cat, magnaflow catback, lightened pulley (not rrm, no udp) and home made water meth injection.

I did an experiment.. the CEL is thrown if the Cap is not completely tighten. This might be because loosing pressure on gas pump??

I made my own water/meth install before the MAF and did tests.. using an OBDII we got great results in IAT reducing in less than 5 seconds from more than 40ºC to below than 25ºC.. then something strange happens and my car stops revving 1 second as if Maf saturated.. no CEL codes and everything's fine.. I am sure that the code is nothing to do with MAF... I have had problems with MAF before and your cars should go on Limp mode when it fails..

 

are you sure that the MAF housing that you made was the correct diameter? if its too large i believe you'll get a CEL

 

Raikiri, I used the same housing as the original airbox.. used silicone couplers from Autozone to hook everything up.. working like a charm for about 8 months or so. best time 16.0 @ 1750 ft... I need to run again since I changed all suspension kyb and tein s tech, removed a resonator that restricted airflow, and need to test water meth injection at the 1/4 mile...


............

For everyone out there I used my maf some time with 3'' piping and yes there were some issues with air flow.. I solved that since I didn't want to cut the original airbox...

Get that cheap looking 3'' maf coupler from autozone
get some 3'' coolant tubing, cut a section so the sensor fits and the other side cut along all the tube a small 1/2 inch so you can actually fit the tubing inside the 3'' maf coupler.. works like a charm.. got it working about 6 months.. then I got tired of it and made own CAI .. painted it black and works great. my filter is on the driver side before the wheel and removed the plastic panel below.. never got a CEL except 1 week from now...

Today I drove to my work and no CEL on.. yesterday I changed to a more trustworthy Gas station and tighten the cap... any information I will keep you updated

 

I had this p0171 and a p0300 (multiple random misfires) and the source of my problems was the RRM CAI, just changed back to my SRI last night and now my car runs like a boss.

It must have taken awhile for my long term fuel trims to be affected because my car was running very poor, couldn't pull at WOT, etc.

Very strange.

 

check fuel pressure.

you're running meth injection on an N/A motor? have you dyno'd it with and without?

 

nerdbot, did you noticed if any air leaks after the maf? that misfires seem to be because ECU didn't recognize that much air entering the combustion chamber, since it is not recognized, enough fuel is not injected thus causing poor AFR's and possibly missfires... the car wouldn't pull at WOT because it entered at Limp Mode.. did you notice if you could revv past 3k or 4k rpms??

 

I haven't dynoed at all... I use only Dynolicious and I will see changes at the 1/4 mile if any... first I got to hook up the activation of the meth injection when mivec goes on using the relay and all that stuff also an activation button so it doesn't activate always.. I check temperatures with OBD-II maybe tomorrow or friday I can get you a video so you can see my poor mexican-engineer installation so you can laugh


My meth/water was almost free.. well cost me about $15 since I bought a cheap spare washer fluid assembly... since I am NA I don't need 200psi of pressure to inject.... I got my injector from a hair sprayer, did tests and I got about 120cc of injection with great mist.. just enough for NA 4g69... i made calculations for that.. (im an automotive engineer btw).. but I just run water and 5% meth no ignition advance changes seen right now. IAT lowers greatly when using this spray.


There's a 06 ralliart turboed here in monterrey, mexico..with gt28rs or gt30 arias pistons and eagle rods, meth, etcetc unable to run since they couldn't flash the ecu.. hahah. I am buying openport and start playing around with my ecu and maybe one day I could reflash mine so I can get advantage of this...
I can't send it to hackish since I can't stop using my car.. I prefer doing it myself..

 

what kind of gains did you yield with water injection? I love the ingenuity of your setup, ghetto as it is I was considering running meth with my turbo setup, but i think i'll wait till the next stage.

Hackish's software is in beta testing right now...so when it's released, you just buy it, like you would with DSMlink for DSM's, and you can tune all you want...

 

haha thanks. let's say I am an engineer with engineer friends all willing to destroy engines for the sake of knowledge... and fun! haha.

Well as you are turboed your meth will boost great since 50/50 meth water will give you better results against knock... methanol works both as a heat remover for the charged air (past turbo) adding water will do the same trick and also avoid meth to ignite in case of accident

I will recommend you to add Water meth from AEM right now.. just be sure to get the 200 psi pump. you need to calculate your spray cc's its easy since there is the calculation.. about 130cc's its good to get 200 hp... friends with turbo setup about 230 whp get at least 20 whp whenever using water/meth...

I have at least 5 friends running this setups 2 civics, 1 audi 1.8t running 32 psi.. jetta gli 1.8t running 28psi other jetta gli 1.8t running 22 and the list goes on and on... I personally tuned 3 of them.. I will work on a 4th tune.... ga16dnet, r18t, k20t and soon ka24det ... the Sentra ga16 will soon have meth.. and I worked on the AEM FIC installation and tuning of this car. also for the Civic R18 with an AEM FIC and the Civic Si with Hondata.. all with AEM Water meth hoooked up.. work like a charm... the K20 with hondata could read knocks and we got 1 or 2 knocks on 4th cylinder only every 3 or 4 runs..

if you need assistance on installation or recommendations feel free to ask me.

just be sure to get all of this after MAF.... my mexican setup is before MAF so I can read IAT and see it actually works.. but I am cutting my intake soon after I take the video for you guys so I can get Maf before water meth.. non boosted maf gets saturated if IAT goes pretty low ... that's because water spray at low temperatures does changes phase to gas thus wetting the maf sensor... this is why you should move water meth after maf..

I got experience on tuning ecus.. that's why I am getting my own openport and start playing with ecuflash.... I already played alot but never dumped my bin hahaha

 

turbo's not in yet...welding up all my charge pipe this weekend...then i'm done, and can begin the process of tuning...

 

after reading your mods we are almost the same setup except for the sri and cherrybomb and aem things.. haha

me:
custom made cai, custom magnaflow catback no cat, cel eliminator, tein s-tech, kyb gr-2, sunpro gauges. kumho ecsta spt ku-31, cross drilled slotted disks + stoptech ceramic pads, custom made water/meth iny, 1 lb lightweight pulley, evo 8 rear wing (cf real wing)

i was planning also to turbo my ra but i dont know hahha.. nice setup... i'll be visiting your post of your turbo setup
