Default Anyone know these tables in Tunercat?

. And what exactly they correspond to?

Fan, Hysteresis, (Coolant Temp.) = 3.0 Deg C.
Highway Mode Spark LV8 Disable Thresh = 100Counts
Highway Spark Cool Temp Disable Thresh = 59.8 Deg C.
AE Enable Min. Delta LV8 Threshold = 20 Counts
Accel Enrich Enable Pos Delta TPS Thresh = 3.9% TPS
A.E. Disable Negative Delta TPS Thresh = 3.9% TPS
Accel Enrich Delta TPS PW Scale Factor = 0 Mult.
Power Enrich Enable Min. LV8 Threshold = 50 Counts
TCC Enable Min TPS Threshold (High Gear) = 0% TPS
TCC Enable Delta TPS Thresh. (Mid Gear) = 99.6% TPS

Thanks...

:D :cheers:

Accel Enrich Enable Pos Delta TPS Thresh = 3.9% TPS
This one monitors the TPS for a change (delta) and if it sees the value it is set to adds a small amount of fuel.

These are a little different than in the 165 ECU, but if I'm not mistaken, these would be where the Torque Converter Clutch locks/unlocks. Looks like in High Gear the TCC is always enabled, and in mid gear its enabled with less than a 99.6 percent change(increase?) in throttle?

TCC numbers are always fun to play with :smash: can't really hurt too much unless you have it engaged at a full stop.

If you haven't look under the Tuner Cats help button at the top right. I'm using a different ecm so I don't know if the help is correct for your ecm.

Nah don't be surprised. There is a nearly 0 help in Tunercat for most ECMs. :)

Heh, yea I noticed Tunercat likes to take the money but absolutely no useful info.

Anyways, I am leaving those at stock levels for now.
Made some timing/fuel/maf table changes, burned my 1st chip and the car fells quite better in 2nd and 3rd gear. More responsive, and 2nd just pulls way harder than before.

I love this shtuff.. :conehead

Tunercat is cool! Thanks for giving me a demonstration. It's close to DFI as far as the basics go.

I dunno. They make what they make and are damn good at it. I wouldn't expect them to be a tuning school also. :)

I found another one :

Overdrive Disable %TPS (In 4th Gear) = 99.6%

Does this mean at WOT overdrive is disabled? (TPS=100%)

Well I would say yes, but the OD is all hydraulically controlled isn't it? The only thing electric is the TCC lockup. It almost sounds like a 4+3 field, but I don't recognize it.

I'm not sure about OD, but I know 1-3 are hydraulically controlled, and like you said I thought only TC lockup was controlled via the ECM.
