NOTE: This is a complete list. Not all are specific for each car. There may be more or less depending on vehicle like Corvette, Camaro, Firebird, Impala SS, Caprice and RoadMaster that came with the LT1 engine
11 Malfunction indicator lamp circuit voltage was wrong for 26 seconds.
13 Oxygen sensor voltage stays between 0.35 and 0.55 volts for 60 seconds. Engine was at normal operating temperature and had been running for at least 2 minutes after start with a throttle angle above 5%.
14 Coolant temperature sensor signal indicates a temperature of over 284° F.

Disassembly of $EE
Here's a collection of LT1 bin files for 1994 and 1995.
94 vs. 95 code
If you install 95 code in a 94 you need to disable DTC 83 and copy over the TCC apply/release rate tables from your old bin.
Here's a few more
WOT BLM Locker for LT1. This little program locks BLM to 128 at WOT with the 1994 and 1995 LT1 engines. I have run this on a chip and tested and it does just that. Then adjust your WOT AFR up 20% and your right about 12.9 to 1 AFR. Made a big difference in my car!
Two tools.
Spreadsheets to use with Data logging BLM in tunerPro for BLM VE tables in Open Office and Microsoft Excel.
MPH calculator, here's a little tool to calculate the right numbers to enter into your bin file if you have changed tires and gears on a $EE 1994 1995 and been told it's the same for OBDII 1996 1997 LT1 engines but have not checked that myself. It does work for OBDI ! :thumbsup:
steveo has taken on the $EE mask and improving the TunerPro RT XDF file. Great work! :thumbsup:
http://www.gearhead-efi.com/Fuel-Inj...223-new-EE-xdf
It is recommeded that this XDF file is used. All data tracing is still in tact for use with $EE-16188051-V3.8.adx
Until they are completer here is a link to where the latest files will be at:
http://resfilter.net/files/carstuff/...DF_CURRENT.zip
Thanks for sharing your work steveo! :thumbsup:
The ADX and XDF files below was built from scratch and a much improved version then what was available which also work on B body cars as well as F and Y body. Some people get a bad connection first time. I have tried this on three cars and found the same thing. Disconnect and second connection is always good solid data. If I can work this problem out I will update ADX file.
The V3 files or higher version work together for Data Tracing as well in TunerPro V5 RT
EEB.xdf is for early 1994 Rev B chips which are very rare. You can reflash PCM with newer bin if you want? It is recommended to reflash using an $EE file.
and since it's been asked multiple times, this seems like a good place for it.
