haha yea I have been hearing that a lot lately, just need to learn more about 1 bar sd tunes

Using my config both O2s (Front) are shown. For some reason the logger doesn't allow me to log my non SAE passenger side O2, so I had to use SAE. Really odd if you ask me.

I did some more work and...

Attached is another log from my driving today, and tune modified after drive. MAF is getting more and more dialed in, 1100-1200 needs some more work due to them still being off. Still getting some of...

I flashed the computer with the tune from Bret, I am able to drive it and log. I noticed that the MAF calibration from right above idle to around 1500 rpm is horribly off. Already it has gotten...

Thanks Bret - Going to try this sometime soon as I just got back in the country.

Yea the slope def needs to be smoothed, I was putting that off until I get the idle fixed. When running with the MAF off the car runs great, no hunting or stalling. I haven't physically touched the...

I bumped the timing by 2 degrees as I already had those tables matching my main timing tables. No change.

It wont even idle now, would a vacuum leak cause this? I had no issues when tuning VE,...

My car is a C5 Z06 with ported heads and 231/236 camshaft. Previous to my clutch job this winter the car was running great. I noticed the fuel trims needed some work so I tuned the VE table, and now...

My main issue was the VE table, now that its much better I am working on the MAF. The % error vs afr was (so far) 10% off at idle, and some other spots. Going to drive around and tune some more soon.

Drove around a bit dong some logging for VE and the car doesn't dip or die anymore (since I changed the VE from 400-1000). The logging shows the VE table needed to be updated so I updated it with...

Here is the tune I will start with tomorrow. I smoothed some of the idle transitions (spark) but if something stands please let me know. Besides for idle sections and WOT it is pretty much stock. The...

Thanks for all the help, tomorrow I am going to start over with a stock ve table and start tuning it from there. I will try my best to smooth all areas that the histogram doesn't hit (this is the...

Went for a drive, it didn't go well. The car didn't stall but when I let off the clutch the rpms hunted up and down (and repeat) until I came to a dead stop and then idle caught back up. I don't know...

I smoothed the 400-1200 region of the VE and it seemed to help, couldn't get a dip below 850rpm. Going for a test drive later tonight to find out if that was truely helpful.

Returned those tables to stock. Still can cause it to dip, just not as frequently, timing does head real low though
.
tune:...

Davecs1: I looked at the tunes and re did my timing, and it helped a little but the car still dips to 600 rpm after giving it some gas. Any suggestions?

I've updated the idle park/gear tables and it seems to help a little, but the idle is not perfect. Still dips some, I will update the base idle air table (subtracting 32.42) tonight and post back....

Thanks I will take a look at the tune. I tried changing the overspeed table, some cells were -13 and I changed them to -11 and didn't notice any improvements but i don't know if that was a large...

thanks :cheers:

I thought the throttle cracker isn't involved when the car is below the set value (1 mph in my case) ? Also I noticed when the car is recovering from the 500 rpm dip it adds fuel to to the tune of...

So I am working on idle now (ve/maf dialed in) and I ran the russ k idle config. Copied those values over (log attached) and then put my idle startup airflow back to stock. The car started hot great,...

I am working on an 02 ls1 with milled 243 heads and a Trex cam. Just did the first round of base idle air tuning using the Russ K config file. There is a hole in the TB (not large) and we used the...

turns out my tune was fine, the plugs were fouled :banghead:

Tried a few different older tunes and nothing helps, can anyone take a look at the tune and let me know what they think is causing this?

Adding my config
