I am helping a friend out tune a CTSV that's got an underdrive pulley and the car was setting a P0068 and P012B. I pushed out the threshold for P0068 so it no longer sets but it still sets the P012B....

Kevin, thanks for the reply. I was helping a friend get the car running and the exhaust didn't have a bung in it yet(currently open header). The goal was just to get the car running yesterday. I can...

Just got a 5.3L swap running today. Mods are 5.3L, FAST 90MM intake/TB, LS3 MAF/IAT, 235/242 .621"/.592" 111+3. The car starts and idles but the idle desired airflow keeps walking down to the point...

I just recently got my 02 WS6 back on the road after a cam swap this year. I was able to get the cold start and stationary idle dialed in before taking the car out. Mods are: Full bolts ons, 243...

I've pretty much got the cold soak start dialed in now. Modifications to the Prime,First, and Second Pulse Mass volume did the trick. I ended up having to add 20-23% more fuel in the ECT ranges....

That was one of the initial thoughts I had, but a few times I would key cycle the pump on before cranking and still had the same issue.



Injector pulsewidth was active during the crank. I...

Hello All,

I recently got my build together and got the idle calibration pretty dialed in. The only issue is the very first cold crank is very long. Any cold start after that, and the motor...

I figured I'd post here to see if anyone could help me out. The car is a 2000 Camaro with a LQ9, LS3 heads/intake, full exhaust, 4l60e with a 4k stall, ebay 90mm TB, and a 235/239 .627"/.624" on 112...

I'm looking for some insight on if I can get my transient fueling any better on launch at the track. I typically see my w/b jump to the mid 15's before it settles into PE mode. Motor is a LQ9, with a...

How can I load in old user configs I had? It looks like 3.0 will not let me load in .cfg files, is there a work around for this? Also, the default config is not reading my TPS and I've tried multiple...

I made some progress since this post. The car now starts and doesn't stall on a cold soak start, however, it still surges for about 3 minutes and then all of a sudden idles perfect. Attached is the...

Car is a LS1 with stock 243 heads, ported fast 90 intake, 90mm TB, and Texas Speed MS3 cam. I always need to give the car help to get it initially started but once it's idling I don't have any...

I thought the Iac's were at zero because I disabled throttle follower below 45 mph. The cam is a 113 LSA. I set my idle set screw back to close to where it was originally and ported in some old RAF's...

So I went out tonight and played with a few things. I ended up deciding on turning the throttle follower enable/dissable speed to about 45 mph. I also readjusted the idle set screw and RAF tables....

I fixed what i thought could be the vacuum leak and adjusted the idle set screw and redid my braf map. I am getting a little bit of vacuum on decel and it is definitely better, but I'm getting issues...

Ed, I didn't actually do a log from cold to hot to set BRAF. I rescaled the iac steps and then took the car on a ride to see how it drove on the old tune. I only ran a log on BRAF at hot real quick...

So tonight I rescaled the Iac steps, lowered the idle screw a little bit, and added about 15% to my RAF table. The decel issue is a lot better/90% fixed. I was playing with shift scheduling/tcc...

Ed,

I will fix the table correctly and retry tonight if the weather holds out. I did multiply the whole table by .9 last night during one of my tunes and it did bring the iac count down slightly,...

Thanks Ed. So I setup a config to log idle cracker airflow and idle desired airflow. I zeroed out the iac steps under 20(Like you suggested). I also lowered the throttle cracker airflow table by 7%...

Hey guys, I just got this setup up and running and am looking for some tune help. The basics of the setup is stock MAF, a 92mm TB, ported fast 90, 36lb/hr injectors, stock 243s, texas speed MS3 cam,...

Bluehawk have you ever figured this out? I'm currently having the same issue with my car and most of the threads I find on the subject end up with no posts on what the solution was.

Hey guys, I just picked up a car with an MS3 cam,BBk intake, and 3600 stall. I took the car to the track last night just to get a baseline for it and the car cut a 1.66 60' on the stock 10 bolt but...
