$EE Mask Anyone here a pro on the $EE stuff? It has both MAF and MAP tables. I can't seem to find any constant or table that identifies when it's using MAP based fuel calculations vs MAF ? -- Joe |
Re: $EE Mask There should be a flag for speed density enable to turn off maf |

Re: $EE Mask Found some of my own posts from 2006 which was the last time I tuned one of these LT1 Vettes. Man I've long since forgot. I gotta find one of my old tuning notebooks :( -- Joe |
Re: $EE Mask Unplug the MAF to get SD. |
Re: $EE Mask I'll have to see what mask files i have because the last one i did had a switch/flag for the sd mode It was a 94-95 lt1 in a thirdgen but motor was out of a vette as the 96-97 were obd2 |

I'm not putting a cam or anything in it. I just did an EGR and air delete so I'll set those features off, maybe change the fan temps, etc. -- Joe |
Re: $EE Mask They are right, $ee is MAF. SD is backup only. |
Re: $EE Mask I think it's on my website downloads page... if not, let me know and I'll email it to yoh |
Re: $EE Mask Yes its maf but you CAN disable it in the definition file, or atleast it uses speed density as primary fueling |

Re: $EE Mask You sure? Last 2 car i did were both speed density and had no ae issues noticed. One was bolt ons one was 383 stock heads hotcam |
Re: $EE Mask Well i dont see any ae tables or scalars anywhere so maybe the maf does do it. It doesnt say in the mask notes i have |

It doesnt say in the mask notes i have I'm on the fence as far as if I'd use it for performance use, but for a stock car it's not terrible. Closed loop correction for each bank, SFI with cylinder trims, and of course full electronic transmission control. -- Joe |
Re: $EE Mask I've worked on several LT-1 Camaro's with Vortech and ATI superchargers running up to about 15psi and those computers did a real good job with just minor tuning. |

Re: $EE Mask Well its been 16 years since I touched one, but as I recall they were doing things to trick the computer. Like running a higher flow MAF and just re-scaling some of the tables (dont recall exactly which ones now). Also running a MAF translator. I know its a band-aid sort of thing but in 2001 the options were a lot more limited. I also seem to remember things like rising rate FPR's I dont recall those extreme external tricks being very necessary on NA LT-1 engines. I was just mentioning the boosted ones as an example of how far you might go with an $EE based setup. |

I disabled ASR on my tune, but didn't realize the CCM on the y-body also controls ASR so now I'm stuck with an intermittent flashing 'sys' light. -- Joe |
Re: $EE Mask Did you find these tables? "%change to AFR at WOT vs rpm" and "%change to AFR at WOT vs coolant temp" |

You know what is amazing to me, after all these years nobody has figured a way to either flash the CCM on these cars, or simply replace it with an ardruino or something like that. -- Joe |

Dang, I'm working on some LCD graphics displays for gauges right now and part of this project is to make a sort of body control module using an arduino mega board. Its a long ways away from realization, but yes the idea has come up and is being actively perused (at a very slow pace). Although my design is all intended to be standalone and not intended to interface with the OEM control modules. Mine works, but I know one day... -- Joe |
Re: $EE Mask The thing I working on is not vehicle specific, its just a universal body controller type thing. It will interface with the gauges I'm working on and has a bunch of analog and digital I/O. But it will do things like windows, locks, lights, climate control, alarm and such. A programmable speedo interface would be really easy as well. Anyhow I have several projects in the works that will have to come first. But this one is in going to happen. |

Re: $EE Mask I have an 84 vette with several issues in the stock instrument cluster. When I get a little farther along on the LCD gauges for my 2nd gen bird, I'm going to spin off a version of the display units for the vette, for a drop in replacement of the circuit board and LCD's. How are the 90-96 units different from the early C4's?. (I'm just barely starting to look into the vette dash right now) |

How are the 90-96 units different from the early C4's?. (I'm just barely starting to look into the vette dash right now) On the '90-96, the gauges are mainly analogue except for this little square LCD in the center, which happens to be the speedometer, odometer, fuel gauge, range, and other things. It is 100% controlled by the CCM. https://cimg7.ibsrv.net/gimg/www.thi...5b2bd65c5c.gif https://cimg8.ibsrv.net/gimg/www.thi...b5c64eacd7.gif https://cimg0.ibsrv.net/gimg/www.thi...951c32f6ca.jpg Some people do this which is pretty ghetto: https://cimg1.ibsrv.net/gimg/www.thi...847930e563.jpg -- Joe |
Re: $EE Mask If I was a bad *** coder I'd try to hack the ccm. But I'm not. So My method would to be to just program an arduino and color LCD to fully replace that center display unit. I'd just pipe in the raw sensor data to the Arduino and bypass the CCM altogether. Thats my way, based mostly on the limits of my skills. Here is a work in progress on one of my 74 Firebird gauges. I'm doing this in a modular fashion so that I can easily port to other display's and show different parameters. This Tach screen will have 2 smaller gauges in the upper corners with a 90 degree sweep. I'll show the gauge readings in numeric form also. For example the tach will show the RPM's in large digits right below the needle. This is a 7" display (barely fits the height of the 2nd gen bird inst panel), I have smaller displays also. And I can very easily (and very inexpensively) do touch screen as well. In fact touch screen is easier to program and less costly than physical buttons. I also have a 3" display in the works that serves a similar function to the one on the Vette you showed. It shows info about the headlights, blinkers, gear position, TCC, OD, and much more. It also can show scrolling text along the bottom if I want to show some type of info.The 3" will be placed in portrait mode right above the column between the tach and speedo displays. I have one more 7" in the firebird that will be to the right of the dual 7" tach and speedo (where the heater controls used to be) that is touch enabled and can show any and all sensor data I have wired up to it (16 analog inputs and expandable to more if I need to). I will have multiple display pages on this one, some of them set up to drill down into small details. Ridiculous amounts of real time analysis based on comparing multiple sensors is possible. Anyhow, here is a work in progress picture of the tach I took about 10 months ago. https://cimg3.ibsrv.net/gimg/www.thi...8d03c86a18.jpg The project is currently paused until I get a couple of my more urgent projects wrapped up first. I probably will be working on it again before new years. |
