which leads me to my next point.... then, modyfi MAF reading to trick the ECU into providing more fuel (while running more BOOST :banana: ) :headbang: :grin: :grin:

how about, instead or building led-based thing.... an analogue voltometer, with a scale from 0 to 1.0V again, the exact measurment is not possible, however the rate of change is what's important.... and how does it vary.... basically, I want an indication, when is it too lean... otherwise i dont really care. so, from the sensor... low voltage - rich, and high voltage - -lear or vice versa ???? FFS, i could even connect my Digital multimeter there temporairly, to see values.... grrrrrrr.....

yeach, thats what i thought....

Thanks guiys heaps for very extensive and great input. Now, I do check my ECU often for error codes, and it's clean, i.e no errors (once i had an error when i forgot to plug in one of the pressure sensors almost ****ted myself when engine died in the middle of the highway ) anyways, I noticed strange blips and stuff in power output which would point to the throttle position sensor. I'll get some quotes today... thing is I dont want to spend $1000 for a handfull of new sensors (they do get quite expensive here in New Zealand). plugs are the ones all other JDM subaru use (forgot the exact model number), but they are iridium NGK and all other subbies in NZ use them. where in the engine bay will i find throttle position sensor and oxygene sensor ??? I will check out that PVC valve when i get home. thx in advance.

yeach, i can make that - thats easy. but i dunno where to plug it in or how to calibrate it, etc...

thasnk for reply. Yes, i have MAF sensor I use apexI pod air filter, they do not need any oiling, and they came out as the best cleaning air filter in several independent comparacment test i've seen. The engine does not take any oil, as long as I change it every 5000 kilometers.... but indeed, if i drive more than that it will start to swallow oil (that is once the oil is worn out). i got no idea how to find PCV valve. :-\ gap might be the reason. initially i set the gap to 0.8mm, was ok for first 1000k's then started missing badly, i drove like that another 1000k's, then checked the plugs and they were black already. corrected the gap to 0.7mm and they stopped missing.... after 3000k's they are starting to miss again... I guess my sub is going to get a set of brand sparking new spark plugs for x-mas :santa:

great. check out this link http://usmb.net/repair/?CurrentDirectory=FOLDER_3f35c591bdc2e0.78531895/&FileType=Article&File=ARTICLE_3f7bb215ea91b8.39054402.art do you think it's worthwile ??? how accurate would it be ??? - i do not need any exact values, just i want to know when it's leaning off to the stage that it is unsafe to run that much boost.

Hello. I have JDM 94' Twin turbo legacy RS. As the only modification to the engine, it has an pod air filter. problem is that my spark plugs are wearing out pretty fast. last time i bought itidium tip ones, and just after about 8000 kilometers they are black and engine is missing under heavy acceleration at the upper end of the powerband. can worn coilpacks be the cause ??? what else should i check ??? what might be the other reason ???

Hello. Did anyone builded one of those according to the article on this site ??? I need more info on where do i connect it up to and how do i calibrate it..... can anyone help ???
