Your TC lock and unlock tables will need to be modified with this new TC
How did I figure what out?
There are tons of calcultors out there you can adapt to a coblalt, or just use math
I have seen their factory and performance tunes....it is all i need to see
Don't forget the IFR tables are still WRONG. Air fuel is TERRIBLY LEAN down low and TERRIBLY RICH up top....
I am sorry to say it, and I know it sounds harsh but GM has no clue what is going on
You will also need to adjust the batt. compensation table when changing injectors
Commanded AFR is 11.5, actual AFR is 11.5 and this is what I was going for. If you look at my thread about stock .vs. tuned, i am using 12.0 and making more power
We know there is more power to...
I forgot to get an overlay compared to his Dyno Day Results, which was with a GM Stage 2 Flash. A note for those using GM's flash. Not only is the air fuel all over the place, they are WAY off the...
If you come in to the shop, or have one mailed out you are looking at $250.00
We will also be programming PCM's with the latest gm flash and our flash, with your VIN and sending them out. Price...
Thanks guys....once i find a way to lock mail order files i will be sending them out
I am talking about a 2.0L Supercharged`SS
You cant adjust the maf table to add in fuel because the maf is not actually seeing more air. By not calibrating your maf vs commanded air fuel, load will be off and you will have improper...
PE EQ Ratio is your DESIRED Air Fuel. You calibrate the VE table to MATCH this Value
PE Enrichment Rate....increase this.
Let me know how it works!
There is some good advice here but I have to correct some statements. Lower spark at idle, will help trim a rolling/surging idle. Running about 10* timing at idle will improve the idle quality. ...
If you are spraying POST MAF, you will not be reaching the limits of the meter as it still thinks the same amount of air is comming in
When you inject nitrous into the combustion chamber/intake...
I dont think they made over 10whp on a stock vehicle....any charts???
Is it possible to send out the .hpt or bin files to customers with HP Tuners, but keep the file locked so they cant ready it...simply write it to the PCM and that is it?
Also, what has to be done...
Sorry guys, can't do that.
The obvious fueling changes, spark adjustments, other adjustments which allows the vehicle to run much cooler. Drivability is better than stock, car feels way better than stock with other not so...
94 Octane, Colder Plugs, STOCK Car, Tune. I think these are the highest documented gains for just a tune and would have been higher if I pulled to 7k...
i have lots of experience tuning all ford vehicles, especially mustangs.
Your air fuel is like that because the gm flash is crap, and they have a poor understanding of how to properly calibrate a vehicles pcm. That flash, they are commanding a 13.0 AFR in the top end,...
Vettes and older camaro's, under dynamic airflow use a high rpm disable function...does this exist on newer vehicles anywhere under a different name?
Correct, in the ford world this is called open loop delay. You want the enrichment as fast as possible when going WOT
