Tune #2014_10_31_0006

Logged several times while minor tweaks were done along the way.

B3613 - Normal PE Mode Enable (TPS%)
sharpened slope from 1200 thru 2800 rpm. 3200 thru 7200 rpm changed to 20.0
B3306 - Cold Engine RPM limiter
Raised ECT 154 - 284 to 7500
Sloped ECT 68 - 133
B3305 - Cold Engine Protection Timer
Increased low temp cells
B0504 - Purge Cannister Min Run Time
Changed from 100 to 13421770 (*effectively disabled)
B0501 - Purge Cannister Min Temp
Changed from 84 to 283 (disabled)
B0502 - Purge Cannister Min Speed
Changed from 10 to 255 (disabled)
B0503 - Purge Cannister Min Air Flow
Changed from 1.587 to 67.720 (disabled)
B0506 - Purge Cannister vs Vac (lbs/minute)
Zeroed graph (disabled)
B0507 - Purge Flow Map Multiplier (Multiplier)
Zeroed graph (disabled)
Notes: Since the purge cannister plumbing has been removed, I felt disabling all the tables would make sense. Seems I have smelled gasoline near the passenger side gas tank now and again, and it may be fumes from the cannister. Not sure disabling all these tables will do anything, but likely can't hurt.

Table B3616 was just tweaked a bit to lower throttle position for higher RPM response and the rest of the table sharpened slightly to bring in PE mode at an increased rate. PE mode should kick in with increasing RPMs even if the gas pedal is held constant. This should work nicely when the turbos also kick in.

Nothing negative was noted during logging, but there still seems to be a slight leanout at throttle tip-in that PE doesn't seem to be smoothing out. Might be another tree that needs barking up. Although I certainly can't complain about the throttle response, regardless of what the graph is showing.

Been tinkering with a "valet tune" lately and have come up with something that works pretty well. The car will not go over 20 mph nor 3,000 rpm. I'm thinking it might be worthwhile loading in this tune if I go out of town for a while just in case someone might break into my garage and want to snatch that pretty blue car for a joy ride. Sure wouldn't be very joyful for him...

Notes: Logging shows that the fuel is cut off when any of the limits are hit. The car is still drivable, as it recovers quickly after the fuel is shut off, but speed and engine RPM is drastically reduced. I could catch up to the car on my bicycle if I needed to.

MAN...............that's a neat trick. Too bad you couldn't have 2 tunes loaded
and use a key lock switch to go between them. Well.....there you go.....!
Another money making idea from navy2kcoupe. It's all yours to produce, patent,
and make millions on. I won't take a penny either

EFIlive already has that capability in some of their custom operating systems. It requires patching a wire into the PCM harness to run a signal pin to ground via a switch to trigger it. I didn't feel like going through that trouble since it really doesn't take long to load in a new tune for the rare times I may want to use it.

Long ago I used to have something like that on my Bronco by putting a switch on a signal wire that killed the distributor.

c4 corvettes had a valet key switch.

So on to the 1990 model year and the big news for this year was the introduction of the ZR-1 coupe known as the "King-of-the-Hill". This engine was still a 5.7 liter small block, but it was a duel over head cam 32 valve V8. It was designated as the LT5 and was rated at 375 hp. A special feature for this car/engine package was called the valet mode. This allowed the owner with an in dash key to have full power (375 hp) or turn it off and limit the output to 250 hp. You could only get this car with the manual 6-speed transmission.
also JET chip had what you are referring to for the older replaceable chip vehicles.
