Since its Zero degrees, I left the car outside to get EGT down as low as I could. Base setpoint is 1050 at 3 degrees F, and 1025 at 25. The desired idle Starts at 1200, which seems a little high, and...

Bonus, I got the performance switch working with an SGS switch (Momentary) using tahoe flex fuel os. IF anyone else is having trouble with this, the pid is not trans perf mode (Yes/no) but Trans...

I finally got a shift. I am using bluecat to set up everything, and when I set the WOT to 6000 it shifter just before the rev limiter. Ther was a hang before the shift as I think I was over the top...

I run another, sitting here with engine off the highest it hits is 93.5 %. I have been unable to change this since I put the larger throttle body in.

Where is the WOT setting? Also if its not at...

I'm heading out to the track next week and would like to get my 2-3 full throttle shift worked out. Currently it never happens, despite lowering the shift RPM and MPH in the tables. Am I missing...

I converted a couple of f-bodies to e85. The injectors need to be bigger, and compatible with e85. I bought a ractronix fuel pump, which connect directly to the alternator for power, and has the...

I have noticed an issue while tuning that I have not seen addressed in here and was wondering if anyone else has seen this and how it has been addressed. If I tune idle while parked, I can get the...

I have a 1999 Trans Am stock with a 411 pcm running flex fuel os from a 2002 Tahoe. Having an issue when cold with idle surging to 2500 rpm, was doing it when warm as well and I reduced the numbers...

Also regarding the 16 degrees, multiplyier reduces in most cases

20 25 30 35 40 45 50 55 60 65 70 75 80 85 90 95 100 kPa...

Yes, i need to direct the vent at the windshild during fogging conditions.

Thanks for posting, ill check differences, I assumed the 16 degrees from the factory was conservative, but see they have...

I have a 2000 Camaro SS LS1 with a fairly large cam. I have been having issue with idle, thought they were fixed, then it suddenly acts like I didnt make any changes. I finally figured out the high...

Well I came up with a solution thats seems to be working ok, I enabled the throttle cracker at 2 mph, off at 1, zeroed out the table. The other tables seem to work only when throttle cracker is...

I tried multiplying rolling idle by 1.5 then 2, 2 and 2 which comes up to 12 x and the Idle at 40 mph drops to 800 rpm, still stumbles when I stop. Is there any setting somewhere that might override...

Ive cut the tabe in half 5 times and and each time there was no change, I even zeroed out the lower end and it acts like its not getting the data from the table. Started when I changed from gas to...

Added logs and tune.

I have 2000 camaro with OS from 2002 tahoe running flex fuel. When running alchohol, The idle while moving is about 2500, and causes acceleration at low speeds. If I disable throttle cracker it goes...

Thanks for the reply and sorry for the delay responding, recovering from spinal fusion surgery.

You mentioned not using closed loop at idle, I don't see where that can be set for idle, just on or...

Have been tuning a Cam Upgrade on a 2000 Camaro SS. Cam is a Texas Speed Tsunami V2 235/240 .629"/.615" Camshaft with Rhoads variable duration lifters. I adjusted the MAF and VE tables and got them...

I installed my wideband outputs to the EGR wires on my PCM, used 18 gauge wire from the console to the computer. When using the math formula provided with the AGM wideband, the lambda numbers don't...

So would a p59 pcm need the tahoe OS to run flex fuel? Was considering swapping due to larger memory, would it be worth the cost?

is it possible to run the alcohol sensor as well if it was never part of the os originally?

I dont have anything to read the bcm with. I am going to have it dyno'd once its broken in, ill see what my tuner can do.

So is there no way to run the Tahoe OS on the FBody without having airbag and service vehicle lights on?

I reloaded the Tahoe OS, set P0177 and P0177 to no error reported, same with p1638 Gen F Terminal which I assume I dont have. Oil change, service vehicle and airbag light are on. Reset oil, may have...

Thanks! I changed the Stoic afr values across the chart, I did get a light, but swapped the tune back before reading the code, so the the light was probably from the sensor not being hooked up. Ill...
