Would anyone suggest running a 94 corvette LT1 bin in my 94 camaro LT1? THe bins are pretty close. The only thing I see different are that the corvette has more of everthing. Even the shift mods I've done to mine are less than what the corvette comes with stock. The spark tables are a little more also. To my knowledge the 94 corvette came with the hotcam?

 

Never heard of the 94 Corvettes coming with the Hotcam. Seems you have the ability to program whatever you want, so why not do that? You could try the Corvette bin if you want.

 

No Corvette ever cam with a Hotcam from the factory.

I have a few different 94/95 Corvette .bin files if you need one. Also have an Ed Wright Hotcam/stock heads F-body .bin file if you are interested.

 

I found the 94 bin on moates. Both can be read by the EE mask so they must be compatible. What I heard was that the corvette put out 20-30hp more than the camaro simply because it had stock headers and a better intake. I have shorty's on full mandrel 3" exhaust and a 3" intake with better filter. Seems like I should be able to clean up my intake, polish my TB, and be right where the corvette picks up, right?

I'll give it a shot. I'll use the tunerpro dashboard to watch for knocks and such and see what happens.

 

The Corvette code will be unhappy if it doesn't have a CCM to talk to. Not sure exactly how that will manifest itself since I don't have an F-body to try it on.

Doesn't seem smart to do that when you could instead simply copy whatever differences you see in the vette tables into your F-body tables.

I think you will get zero HP from these changes. Differences in the stock ratings of the Y and F LT1 were due to hardware not software.

I recall no significant differences between stock Y and F tunes, but it's been years since I compared them so my memory may be poor.

 

I noticed that the cal file from when I got my f-car tuned says Y car. I think I saw that in Tunercat someplace, can't remember for sure. Works fine.

 

I've ran F-body bins in Y-bodies, don't know why it wouldn't work the other way around.

 

If you put the corvette tune in your camaro the A/C will not work. The same is true for running a camaro tune in a impala.

 

On closer inspection, both run nearly identical VE and spark tables. Only a one or two difference. I do notice a difference in MAF sensor calibration table, knock attack/recovery rates, cylinder fill trim, DFCO enable.

 

So you took a stock F bin and burned into a Y car and had perfectly normal operations?

My experience was that with F code in a Y car, you have two master devices colliding on the ALDL channel so you can't establish reliable comms with the PCM and you then have to bench flash back to Y code to get things back to normal.

The explanation for this situation came from one of the well known professional LT1 tuners, and I confirmed his diagnosis by repairing with a bench flash.

Since I couldn't even monitor the PCM with F code in it I did not try running my car with it, so I can't report which other systems would/would not work correctly.

 

Moved to computer/diagnostics forum...

 

I've also noticed some differences in DFCO and WOT conditions. The corvette went into WOT earlier by the %Change to Fuel/Air ratio vs rpm at WOT and %Change to Fuel/Air ratio vs cool temp at WOT and %TPS Threshold for WOT vs RPM (High Cool). THe DFCO Enable %TPS threshold vs RPM was also close to 0% in the ybod vs 12% in the fbod.

 

I just did "check VIN" with Tunercat on that file and it says for 1995 Camaro and it ran fine in my friends 1994 Corvette.

 

I just did a data log and this is what I have. It was noticeably more responsive with the corvette tables listed above installed.



Throttle position and MAF readings are on the right axis.

I was expecting it to go full lean faster or something. Does this look right? There was a little quirk with the right o2. Don't know what happened there, but I think its because of running the dashboard with the datalog at the same time. The display was kinda hickupy.
