Re: 408W - CL @idle leans out and runs bad - O2s stay at .8v

Thanks Decipha, much obliged. Well, turns out that both O2s were bad (I just replaced them and tested again - CL is working like a champ now). The car sat for a long time and my guess is that at some point that fuel went bad and that ruined the sensors. That is about the only thing that I can think ...

408W - CL @idle leans out and runs bad - O2s stay at .8v

Hi guys, I am hoping that someone can help me troubleshoot a closed loop problem. I am currently running OL at idle without issues and the car runs good and is actually driveable, but as soon as I enable CL lambse goes full lean (19) and the car runs poorly. I have also noticed that the O2s never ge...

Re: Tuning turbo 5.0 with sct tuner

Hi Vinnie, I believe that MAF is going to be too small for your combo. Check out the following info on that MAF, the claim there is that it will support up to 275HP. http://binary.uta.edu/EEC/MAF.conversion/MAF_Transfer_function.html You definately do not want to peg or max out the meter. Also, you ...

Code 15 - EEC permaneent Read Only Memory(ROM) Test failed

Code 15 is perfectly normal when you are running a chip or a tweecer. This code basically points out that the checksum value does not match for the ROM that is being used. You can just ignore it.

Rick Firing the injectors is correct if your cam has no overlap. The larger the overlap the more of a chance the fuel will go out the exhaust. The injector timing has two objectives. One to cool down the engine and get better fuel atomization by spraying the back of a hot closed intake valve. The f...

For example – Enter 320 where you currently have 352 So your saying we should lower the #'s "not raise them" when using a larger then stock cam ? Basically, the smaller number is earlier in the intake cycle. A larger number is later in the intake cycle. If your cam has more duration than the stock ...
