1. Can this program be used to disable trouble code's?
I have a few things that have gotten removed over the years and they trip codes. Not a big deal because they wont turn on the CEL, but they can be quite annoying when watching datastream while driving. About every 30 sec. or so the scanner will pop up a message saying DTC triggered than begin to record pid's. This can be aggravating when I am focused on a certain thing. The codes that it is triggering is for the Air Intake Heater, Wastegate Solenoid, and EBPV. There might be more but cannot remember. 2. Can you change the programming to alter when the wastegate solenoid is activated? I have twin turbo's and have only one wastegate on the primary charger, and the gate is being controlled with a manual controller. I plan to add a second gate to the secondary charger and thought it would be pretty cool if it could be controlled with the factory solenoid. 3. Can the programming be changed so I dont have to run a boost fooler, and how would this effect everything else? I think thats all for now but I know there will be more. ![]() |

Good luck with the above. Like I said, these aren't guaranteed to work but I haven't had any trouble running this way.

Yes I am using the Genisis
![]() As for the map sensor the only reason I would want to enable it to see higher boost is so I can use the factory wastegate setup. If it will read 25-27 PSI that will be perfect, thats about where my drive pressure on the secondary starts to get a little high and just gets worse from there. Looks like I have some experimenting to do, but I need to focus on one thing at a time. ![]() |

I went to a scan tool demonstration the other night and just about had myself convinced I needed a Verus.
![]() It would be handy as hell. A scanner....Windows XP....a 4-channel scope.....all of my tuning software on it instead of the home laptop where my wife can accidentally delete stuff (yes, she actually does that). Don't get me started on wanting one again....... ![]()

Alright got a couple more for ya:
What is the reason for the reflash when installing a LL injector in #8? What happens when a regular injector is installed in #8 with the reflash? What are the effects of the blue CMP sensor? I have read that timing will be retarded when using it but cannot understand why. Let me explain, I have been chasing a random miss on the # 8 cyl. The miss is only noticeable @ idle and comes and goes with a rhythm to it. I was thinking/ reading about IPR duty cycle being to high(dual hpop's). Also read about people experiencing this with the "new" gray cps which I currently have. I purchased the blue on from international remembering the fad from a couple years ago, only to discover that there were alleged issues with them. Then started thinking about the reflash for the LL, and curious what changes were needed. WOW... a little jumbled but hope it makes sense. ![]() |

There is almost zero change between the LL8 and non-LL8 programs. In fact, the reflash can be (and often is) used whether or not you had the LL8 injector installed.
The reason for the blue CPS timing shift may be related to how the sensors are manufactured, with some folks speculating that the output signal from the sensor is not quite as strong as the black CPS while other think it might just be that the inductor is shifted a little bit in the sensor housing. I don't think anyone really has an answer on that. Not sure what the cause for your miss is. Can you isolate it to a specific cylinder?

It is consistently #8 cyl. Strange because it only happens when warm, I have changed injectors thinking it was a worn poppet, but there was no noticeable change. Whats even stranger is how it "rolls through" the miss. Like it runs smooth than will miss for a few seconds than run smooth again. But sometimes it will be a steady miss. I have a couple programs with reduced ICP duty cycle than I will try and see if I can get a change. But all this talk of the grey CPS causing a miss on #8 got me wondering if this could be my issue.

Well here's a video. This is the best I can get it with dropping ICP duty cycle. Kinda hard to tell from the vid but listen closely.

Sweet.... got it working now, thanks Bill!
After many attempts I have been able to get the idle pretty smooth by dropping ICP + duty cycle+ PW just a tad at idle. Why is this? Last edited by 907DAVE; Tue, December 1st, 2009 at 02:19 AM. |

My guess is that the maps you listed are just a bit too "much" for a desired idle speed of whatever is programmed. When the maps ask for too much of something but the idle speed is commanded to be lower than what is able to be maintained with the higher PW in the map the PCM constantly tries to correct itself. There's a reason the "lope" tune works the way it does......
By the way, have you adjusted any parameters that I listed above?
