248/254 114+2

Got it to idle at 900

stock pump is good for 450-460.

Put in a walbro 255lph with a hotwire kit and it is good for about 600 with stock lines. (i've seen cars push more, but this is a conservative number)

install a...

I had this problem really bad on my car (I didn't even have to be at full lock, just a slight turn of the wheel was enough to bog it down and stall it out)

After doing some logging I found that...

I had similar issues with my car, in fact... I had it VERY bad (18-18.5:1 AFR until the car reached 170+ temps).

I recently changed the ECT Enrichment table values in the startup temps to 1.1 and...

And once you've populated the table and you're ready to enable it and make adjustments, just change the Data parameter in the map to your BEN Factor.

initially you will want to disable A0003 so that you can populate the A0007 table from your already good VE table.

You will do this by logging and using a map to record the VE values from the main...

they probably only made changes to the high octane table and left the low octane table stock.

you need the 12212156 calibration, which you can get at http://www.holdencrazy.com/EFILive/stockTunes.php

Make sure you use the 02020005.tun/cal from the COS#5 files. The other set is for the...

yes, you can.

But I believe all you really need to do is update straight to the Custom OS 5, and use the 12212156 .tun file to flash the calibrations into the PCM.

Correct. Which is why cams with lots of overlap kill catalytics. The cats really like to stay at or above (within reason) stoich.

What tordne said is pretty much exactly what I did. Except I did limit mine down to under 3000rpm and below 25% throttle. It's pretty difficult to really get good values outside of that area....

It's not that most of these people don't want tutorials... the more information that is out there, the better it is for everyone.

However, I do believe the tutorials should be done by an...

I agree with the reasons of some of the others who said no. Tuning is about knowing why a change has a certain reaction... which really cannot be explained through a tutorial... it is a trial and...

It seems to be a pretty common issue among SD tuned cars... mine runs like complete crap until it is warmed up... AFR at idle sticks at about 17:1 and is crazy lean all over the place if I try to...

I can't get the calibration file to download... anyone else able to get it?

btw... you rock Ross!

I was wondering the same thing... but when looking a little more into it, I found that 3647 is in the Holden OSv5, but not in the F-Body OSv5... even though it was in OSv3 :nixweiss:

that zip file doesn't have any valid EFILive files in it.

I know with the LS1/LS6 control panel, you must load up the control panel prior to starting real-time scanning and logging. It is probably the same with the allison control panel.

Why did HPTuners not come out with tuning for the duramax?

Each company has their own ideas on which markets they wish to focus on.

I personally don't see a market for half the cars on the...

With fuel trims on, and bidi controls, I can on-the-fly adjustments for both air/fuel and timing with EFILive, then make the appropriate adjustments in the tune file. On the street, real time tuning...

well i've gotten my TPS VE table dialed in to within +/-2% between 0-3000rpm & 0-20% TPS.

My setup is in my sig, and with the largeish cam I've always had some driveability issues, and most of...

Well I got bored today and decided to start playing with the TP-VE table as well. I started plotting out the data a little bit. It sure is a PITA to get all those areas plotted. I turned off all...

That fixed it Chad!

It is VERY funky... but it appears that changing over the whole commanded AFR table to 14.63 and moving the PEvsRPM table to 12.x has fixed the issue.

I'll get out here in...

Desired Airflow needs to be that high to keep this motor idling properly.

Car's setup is a 408, AFR 225s, 248/254 .622/.612 114+2, 11.3:1 compression, FAST 90/Nick Williams 90mm, SVO 30lb...

emailed it to you.

For anyone else that might want to take a gander and offer a new perspective.
