How would I do that? Just decrease timing?
Fixed the trimming issue. Is there any way to get rid of the bucking that happens between 1500 and 2000 rpm? It's a big cam.

Thanks Hondaeater.
I started over with the tune.
I'll post the tune and log files later this week.
I adjusted my throttle body screw and opened it 1/16 of a turn. No more stalling issues.
...
Cracked the TB screw open slightly. No more surging or stalling.
Drove "ok" for 15 mins and then all of a sudden went pig rich with the AFR reading 8.8. I think I have a bad coil, plug, or wire....
I'm going to play with the TB tonight and open it slightly. This weekend I'm going to see what I can do to keep closed loop. Otherwise I'll go open loop.
I think it needs more base airflow.
You're probably right. Here is the latest tune and data logs. Less stumbling under load but car wants to stall more. I sent you an email Ben if you're able to help me with the tune.
Anything else...
Here is the rest of it:
Absolutely.
Here is what I found on another forum too that I would like to share.
Is he referring to the HOT and COLD tabs under Power Enrich>Throttle?
Sent u an email Ben
Thanks guys. I?ll do a new log tonight with more channels.
The car has a 244/256 cam.

Open loop is pretty good but in closed loop it trims too much fuel off both banks and causes a bad stumble under load and the car goes super lean on the...
Thank you.
This ever happen to anyone?
Idle used to hover around 14.7 AFR before electric water pump was installed. After I installed it, it's now 12.9 and takes about a minute or two to get back to 14.7 but...
What do you do when there is no resolution to your ticket and support hasn?t responded for the past three emails in the last month?
VCM editor and scanner keep crashing. Bricked one ECM. Bought a...
For those of you that are bricking ECMs, you can mail your ECM away and have it unbricked by http://www.pcmcalibrators.net/
I also noticed sometimes my scanner will crash the same way the the...
I'm another victim. Just happened. Tried unplugging the battery for 30 mins. Loads the tune part way and then VCM crashes and shuts down completely.
Thank you.
Switching back to Delphi tomorrow.
Here is the complete list of mods:
Trick flow heads.
228/228 cam
Long tube headers.
102 TB
FAST intake
LS3 fuel injectors
3" true duals.
Mighty Mouse Catch Can.
When accelerating I notice my MAP KPA will drop at anything above 2800 rpm leading to a lean condition. Tried a new MAP sensor. Same issue. Any ideas?
I have a FAST 102 intake and 102 TB. Used a...
Wideband was fine.
No vacuum leaks.
Rechecked the injectors. Despite the shop and the seller telling me they were 42# LS3 injectors, they were not. I should have double checked myself and not...
Ok. Actually, I'm going to borrow a buddy's wideband next week and use it instead as a sanity check.
The wideband is right after the header but yeah, it could be off.
Midas checked the car today. No vacuum leaks. They said even when they loosened one hose, the car would start surging and it's very obvious...so no leaks.
K I'll do that right away and post back.
Thanks.
I'll take another look this weekend thanks.
