Look forward to searching for some stock LT1 Bin Files

i'll help ya as much as i can, but tunerpro with my definition file is a damn good start, considering most stuff is documented:

Steve thanks for the offer. I was looking a stock LT1 with A4 so I can work out some Transmission issues with the lock-up going in and out. I beleive I'm going to have the valve body updated to fix the issues. As for the Tune that's in there I did the email order through LT1 PCM Tuning with Solomon getting me close. Thanks Again Ken

The converter acting up is likely in the tune. Have you got TunerPro with the correct xdf and adx files setup so you can log and open bin files? Have you got Winflash or another program to pull the tune and look at it?

There are a number of stock tunes stored here;

I'm hoping I can get it straightened out with the stock trans settings. I do have the RT Tuner from Tuner Cats and a Trial version of Data master for data logging. Unfortunately until I purchase the Data Master registration I can not access the trans info. Does Winflash record the trans Info? The trans has been rebuilt but I'm not sure what was done as far valve body updates. Other possible issue maybe the less exspensive Dayco Torque Convertor. What I 've read about the 95 4L60E was that is was the begining of a new version of the 4L60E where GM started adjusting how quickly the TC Locks-up. I also read some articles about staking the TCC valve or installing a longer spring to keep the TCC valve from moving and making the trans act more the 92-94 4L60E's.

I have aready download a stock 95 LT1 A4 for the F-Body only thing is I'm running the caprice/impalla (all cast iron ) LT1 with the LT4 HotCam Kit with Camaro/Vette 3.5" MAF Sensor 3.5" Cold Air Intake with 58mm Throttle body. So don't think I can't just put in the Camaro or Vette Tune. Anyway I'm almost finished with a modified version of a purchased tune while incorporating alot of the stock trans setting that make sense. Hopefully I will get it loaded and datta logged Saturday. Hopefully it will stop raining here in NC, so I can run it through 1st & 2nd at WOT after i see everything is ok. I really need to get the Datta Master registered so I can view the trans.

You have the OBD1 RT Tuner? TTS Datamaster will log the transmission without registering unless a recent version changed that. You can bring up the recording window 20 times. In the recording window, you have to switch from engine to engine&transmission or transmission to get the transmission data. Then, just switch to a different port when you are flashing and switch back to the correct port to log again.

Or, download TunerPro RT and the xdf file linked by steveo (which is awesome work) and the adx linked below and use it to both log and tune. You can use Tunercat Tuner to tune if you want and to read and flash your computer.

Yes it's the OBD1 RT Tuner.

I will set it to engine and trans tomorrow.

There is a huge amount of information on here. Man do I have a lot reading and understanding to figure out.

94 to 95 are different bin files as are 94 to 95 transmissions. So what transmission do you have? 95 went to PWM TCC lockup. The bin files should not be switched.

[nchittman]

I agree and have the 95 version. I have been using a 95 F-Body LT1 A4 for comparing the stock transmission settings to my purchased tune that was set-up to be fimer and shift later .

I mentioned the 92-94 trans when I spoke of a fix to the 1870 Trans Code by staking the TCC bore to stop the TTC valve from moving in the valve body. The way I understood the article was this staking , made the 95 trans function more like the 92-94 by having only the on-off lock-up solenoid working the TC Lock-up.

Thanks

The main things to know are the gear, throttle position percentage and the speed to adjust the TCC. Then, you open the engage and release tables for the TCC, pick out the gear and %TPS and look at the speed in the cell that corresponded to the driving condition when it acted up. You then change it to what you want it to be.

Each gear and the TCC have the same settings. Each upshift, downshift, TCC lockup and TCC release is a curve using %TPS vs speed.
The transmission will downshift or release the TCC when the speed is below the mph corresponding to the %TPS in use.
The transmission will upshift or apply the TCC when the speed is above the mph corresponding to the %TPS in use.
The transmission will do nothing when the mph is between the two speeds in the tables.
And yes, the release or downshift speed for each %TPS has to be lower then the corresponding apply or upshift speed.

Thanks, This makes alot of sense. I will take another good look at all the trans and TCC Tables.
