PCM Traction Control is ignition retard.
Traction Control braking cooperates with but is separate from pcm.
Disabling pcm's Traction Control does not disable Traction Control braking.

The part of the table that represents the most sedate driving (drivin Miss Daisy), 14.7 is fine.
In fact, for decelerations (those not covered by DFCO) feel free to target as lean as 15.2 - 15.3, if...
FlashHack to read .bin from 16181333 & 16188051 pcms
TunerPro & steveo's $EEX to copy & edit the .bin file (the RT part of TunerPro is superfluous here)
FlashHack to write your .bin file onto pcm...
Each pcm has limits to what it keeps from the previous engine run.
In other words, not ALL the changes; some, maybe most - depends on the pcm or what the .bin file allows.
Powering down the pcm or...
Capt1501,
why did you change the 2Up3 shift @ 00.00% TPS to 0MpH?
At what coolant temp does that electrical fan start blowing?
'96 & '97 OBD2 LT1 pcms are STILL the bastard stepchildren of the tuning world.
There are very few OBD2 LT1 mail-order or ride-along tuners left.
For slightly more than the cost of an OBD2 LT1...
Sorry for not getting to know him, but still grateful to him for what he left for us.

EGR Min MAP > 103KPa
EGR Enable Min RpM 6375RpM
EGR Enable Max RpM 6350RpM
EGR Enable Coolant Temps (both) > 116C
No need to zero the EGR table with constants set as above.
OE IronHead LT1 is 10.5to1 compression.
If he uses the gasket that goes with the iron heads, but with the aluminum heads instead, what will his compression be?
I'm not a lawyer, I'm genuinely...
'Have to be' is a strong phrase.
If you use the aluminum heads and cam, you'd be better off using the '95 F- or Y-car spark tables.
If I were not going to port the heads, I'd use the iron heads,...
No insult intended by any of the following.
More than 11.0to1?
OE LT1 thermostat is 180F. There's a 160F thermostat available.
My LT1 experiences (sedan & wagon) with 160F tstats did not yield...
nilak, IFF I were stuck in your shoes (big if), I'd start by:
a. calibrating the spark map using 87 octane instead of 91 or 93
b. NOT using WOT-PE below, say, 2750RpM
c. under-utilizing WOT-PE...
Never heard any definitive news, only that those cars also use the same optical sensor. Don't know for sure if it's actually true.
Same goes for a Nissan 3.3L V6 ...
(No, I would not be.)
No thanks needed. Plenty of the characters on this forum are far more helpful than I am.
It doesn't typically lead to detonation with LT1s.
Anyway, if you're gonna delete it, you disable it via the pcm by
1. raising the EGR Max RpM constant to 6350RpM, AND then also the Minimum RpM...
Thought the sacrifice was a Mitsubishi 3000GT / Dodge Stealth?
As in, I could swear that the '90-'00 also uses the same Mitsu optical sensor as the LT1 Opti-Spark?
As for roadside assistance, there are other options besides AAA, especially if your credit card and/or car insurance policy likes you.
Want to supplement my OE jack with an exhaust filled airbag...
Every LT1 car should have a milk crate or somesuch container with an entire spare LT1 ignition system - don't forget the Opti-snorkel / Vent & Vacuum Harness.
Any other small parts that you would...
WOT-PE is not a Closed Loop 'Disablement'.
It's a temporary subset of Closed Loop. (Same goes for Highway Mode / Lean Cruise in other pcms, by the way.)
It just goes off the last non-PE BLM...
While this is absolutely true, IF one had enough battery to store enough energy prior to (say) a 1/4 mile run, the parasitic load could be minimized during that following 1/4 mile run.
Makes me...
The $EE definition files developed by jthompson, dzidaV8, kur4o, and steveo are several steps ahead of TunerCAT's $EE version DO.
Between their newer definition files, and what $EEhack is capable...
If you mean, the 700R4 / 4L60M-not-E, the 12200411 does NOT.
How could it? The 700R4 is a purely mechanical geartrain.
From the pcm's point of view, any purely mechanical transmission may as well...
They're moving even harder toward the JET / CAT business model than JET /CAT: pay-to-play per play.
Anything after HPTuna Version 2.2something, the gatekeeping gets serious.
They probably figure...
