Saw a thread that might help solve your cold idle issue I cant beilieve I didnt see this when I had my ilde issue

steven does have a good point but oddly enough I started noticing idle issues as well and NA no less. Sure it could and very possibly be tthe colder temperatures.

How long have you been running that boost level and orr how different is your tune from last winter.

I saw this beffore I lefft for worrk which I needed gas. Prices had dropped. I keptt thinking to myself is tthis screwing my scalings up considering in wintermonths gas goes down as there is more additives in fuel than full 89 or 93 octance especially in colder areas because gas will oxydize w/o heat so thus fuel companies put addditives in there and gallon for gallon there is less"gasoline" and more addittives in the winter.

May thats a cmplete hair bran idea but I see no reason why it couldnt throw off your precisely tuned scalings and you STFM ad LTFM readings...

 

In addition:

Throwing a 507 code (idle higgher than expected along with either fouled plugs or something up with my stock scalings or injectors going back (will check with evoscan in the morning) Its leading me to believe its foulded plugs as it has a tendency when the car is colder than warrmer. Have a "skip" sensation on accell and decel however code doesnt quite reflect that. HOPE ITS PLUGS!

 

Use evoscan to adjust the biss screw on the throttle body to lower the idle

 

Thats the plan. Im a bit more concerned with the acel and decel throttle jumping. I dont see how the biss could be contributing factor with this and the idle is a bit high but not extreme. It cranks VERY low even with a brand new battery (had idle flucuation issues with a deep cycle battery that was going bad and did fix that problem). Low Im talking starting idle is estimated at 550-600 and slow increases as temps warm or switch to close loop. Will identify that as well while adjusting screw.

Was intending on buy new spark plugs (NGK) but went to the store and realized I had no driver side head light ($40) thanks auto dicks). Im not overly impressed with NGK and cannot understtand or justify 22 dollar spark plug (singular) that was specially laser cut? Has anyone experienced this. I typically (In past cars) gone with iridium $11/plug. Just thought I would share on here since the topics are fairly relevant to each other witth consideration of weather changing evoscan and ecu readings.

 

start on page one . If money isnt much of a option, I always thought a Disco Potatoe (yes its a real name, I thought someone was messing with me as well) made by Garrett, would be one of the most optimal turbos. HOWEVER*****the other aspects from what I have read for the past year and some change and reading and reading, r3complies video series per youtube or wiki page, and Merlins Guide to ECUflash for EVO 7/8/9 have the potential to make your build take longer than you might currently think. Im far from any expert on this as I just started my build recently I still have a expedition ahead of me as far as learning. Read the stickys, read 03's build thread from page one (Iv done it twice) and ANYTHING written by the following individuals; TEPHRA,r3complie jcsbanks, mrfred, phenem, jack_of_trades, SENATE, RoadSpike, green bandit, hornstarbu, ryancb, malibujack, jakemiester, (sorry for those that arent off the top of my head as iv been translating my ROM maps and tables to V7.) If you come across a build thread by any of these guys treat just as previously stated, start at page one and read. If they dont have a build thread I would consider jotting down notes (seems a bit elemetary but I wish I would have, even in build threads as I try to reference majoor points and cannot find them because the thread is 200+ pages).

Train if ya want to be a jedi haha jesus why cant I stop working on this...im flat out delerious and I have to work in 3 hours

 

Thats why I went with the Garrett T25. Spooling starts at around 2300rpm on mine. Havent heard of anyone using the shim in our rides. I believe 03 bought one but decided against using it.

 

was the t-25 what RRM used in their kits Grind3r? I long debated and bought more than one turbo before deciding to use the evo 8 turbo. I do know the t-25 mocks up well. did you run into many issues on the tuning side of things per ECUFlash or are you using alternate EMS? im waiting on fedex to shw up with my boost gauge and greddy oil adapter so currently bored at the presentt time

 

The started with a t25 so you could use there headers with it. Then they switched to the evo 3 16g knockoff....(long story) with a turbo mani. We are all on ecuflash/evo rom's

 

love that part

 

No RRM Kit. I believe they use a 16g like the evo's. but I have yet to hear what the actual brand of it is. I didnt run into any real big issues on the mock up. I had to fab my down pipe. all my intercooler piping was modded a little as well. I didnt use an oil sandwich adapter on my setup. My feed line is T'd out of the oil sending unit sensor. Tuning was originally done at English Racing since they are only a few miles from my place. But I have been fine tuning it myself for the last month or so with ECUflash and EVOSCAN with the help of 03, ryancb and roadspike.

 

Ryan would know Read his thread.

 

Thanks Jake....jab the knife a little deeper kidding..

 

LOL its all done and over with now so I'm sure you can laugh

 

Hey have any of you guys bought the black depo headlightw with HID's pre-installed? I pulled mine out today because one light is dim compared to the other and so I was going to swap sides to confirm if it is the bulb causing the issue (hoping the dim light would now be on the opposite side) the only problem is I cant disconnect the bulb from the wire harness. I swear its one whole unit but wth good would that do. If anyone has these and had to replace a bulb lemme know what you did or if it just slide right out like its supposed to.
