Idle w/1000cc injectors and 280 cams with stock ecu and maf...

Sounds like it needs a lil more timeing. And you need to get a aem bro to get rid off that cel. If your car was tuned right the cel will take away timeing at idle but you can still get around that. Nice whip did you paint you trunk black or is that CF

 

Pretty dam good, for 1000cc's Did you tune the idle yourself?

 

I dont think it is a timing issue it actually sounds real good for 280's.

 

My cel is a bad rear o2. I have a new one I need to install. If you watch Evo Scan my idle is pretty solid at 1000 rpm were I have it set. I bought a Lancer es trunk and painted it black...

 

Wow that idles as good as my 272/264 setup with stock injectors at 1100 rpm.

BTW Another way to get rid of the cel is to purchase a creader off ebay

 

Creader just resets the CEL Light, the problem is every time you reset the ECU it has to go through a drive cycle to complete all of its tests (used for passing an inspection)

 

His idle is actually very good, the CEL light is an O2 sensor from what I gather.

An AEM may get rid of the CEL, but it won't make it legal to drive nor pass an inspection.

My car actually has a similar setup and never gets any CEL lights.

 

good day,
I did not listen to the file, but with an ems I found a little extra timing helped with idle quality. However if you have a steady 1000 rpm you are doing better than I. mine goes from 950 to 1050, that's with the revolvers (listed as a 262 cam) and a paltry 660 injector.

so Jack you have the 282 cams and feel an OBD2 test can be passed? I guess it is different than a sniffer test. I ask because I just felt it would be a no go. So an OBD2 only asks the car if anything is wrong?
I am going to be switching over from a hydra to the ecuflash in order to get plates next winter.
secondly, will a cel eliminator bung extension actually keep a cel light off on a catless car? not that I would try that at an emissions test.

 

Well, the cat is required if you still have a sniffer test, but yeah, federal law requires you to pass the OBD-II tests, many states no longer put the car on a sniffer if the car is OBD-II compliant.

My car does actually pass a sniffer test though, but the car has a cat, and it is approaching the limits of the test..

As long as the car runs in closed loop properly, and the catalytic converter is efficient enough at idle, it should pass.

So far the evidence I have is the mechanical eliminators generally work correctly, the main problem is visually its pretty obvious that their on there, besides the obviously missing catalytic converter, if you wanted to be stealthy about it you could hide a pipe and the extension under a heat shield.. But that goes against my personal feelings on what I feel is "The right thing" to do, which is to make the best effort to have a clean running car. If it can be done without a catalytic converter, then I'm okay with it, but the government isnt..

So, when I tested my car on the sniffer for the hell of it, it passes.. However it took some time to get everything dialed in to eliminate all the Cel codes, so the tests can complete sucessfully, when they do, the car passes an OBD-II portion of my states inspection. Visually my car would also pass as it has all its emissions controls intact, and in my state, sniffer is not used. The only portion of the test that ever comes up is the safety portion, they always seem to want to sell me new brakes, or tires, or wipers, claiming mine are no good, which I know for a fact is not true as my car is well maintained.

 

when you start messing with timing at idle you really start messing with the amount of micro carbons produced, more timing might mean a more stable idle, but doesnt mean that it will cure your CEL or make you pass emmisions.

but if you up the fuel and timing at idle, its only going to hurt your chances of being stable at idle. just food for thought.

 

lol, those dirty gas station attendants!

 

True, altering the timing and fueling at idle will affect emissions, sometimes pretty drastically, if you try to leave timing as close to stock as possible, and the car runs in closed loop properly at 14.7 AFR, then it will pass a sniffer, though it may register some emissions high due to the cam overlap, in my case it was still within the test limits. Again, sniffer isn't used on OBD-II vehicles in my state, this was only done as an experiment.

 

Hypnotic sounding audio

Is there a limit on the # of times you can reset the battery, like that of # of flashes?

Interesting thing on this OT subject is that whenever I battery ECU reset the car will Idle high for about 20 min

 

Nah, disconnecting the battery just clears the memory, High idle is really likely due to the BISS settings since the idle stepper resets to its home position until everything resets itself..
