I've never had an issue just completely zeroing them out.
You would be better starting the question off with what year/ model/engine then narrow it down by OSID
You have a stock tune repository if you log into your account.
This isn't a perfect world. I just looked at your log and I do not see anything wrong with that at all.
We make a bunch of different electric fan kits for TBSS.
I don't. there are are multipliers and things that you can't see behind the scenes. So if you changed this stuff there is a decent chance you are also not getting some multiplier that you can't see....
I see this often. 3 times in the past week on here alone.
There are two settings in the transient section that need to be changed.
ECM 2284
ECM 2282
I've seen some people say to reduce...
With a injector of that size you will need to reduce or zero tables ECM 2284 and also ECM 2282.
This is critical.
Some people say reduce it.. I've never had a issue zeroing it out.
That...
that doesn't look great to be honest. I'd continue to watch it... especially under a heavier load.
It sounds like you got a miss other than that.. have you done the simple things? Wires/...
Does it cool at speed? If so it might be a fan
Have a good A/C tech put the system on a vacuum, check for leaks, refill with proper amount.
It sounds like you have another issue to be honest. If you diagnose a bad fan clutch which is computer controlled on these. Than I would do electric fans because of the cost replacing the stock...
Just to be clear.. i wasn't referring to anything min airflow related.. I would be sure that forcing it in speed density or open loop improves or doesn't change the situation. Maybe retest. It's...
Your post sounds like a non native english speaker so there might be something lost in translation.
A ZL1 has two IAT sensors. You want to pay attention to IAT2 for a ZL1. That will tell you if...
Where. what timestamp is the car surging?
I'm surprised this feels good at WOT. It has very little timing in it.
Is the surging better if you forced open loop? Is it better if you force...
sure but better to ask questions here. might help someone else in the future.
when adding a the pid search Short term idle trim and long term...
That should find it for you. It will be in engine - idle xxx
It doesn't look like he has that peak intentionally.. like he's tuning for the lean spot you are seeing..
Rather it looks like the harsh boundary edges when the RPM/MAP boundary tables could use...
yes.. computer controlled electroviscus clutch. They have problems.. usually lock up when they go back. But i assume it could go the other way.
I'd do electric fans if it was confirmed bad. ...
If I do 100 cars I might touch idle airflow pids on 1. Most people who go into that are masking other problems.
Fueling, the fueling as the engine decelerates, and timing are key for a good...
The fins will get blocked by debris. Externally.. not internally.
FIC did that. Among others.. It comes after they refit/redrill/reoriface whatever to a stock injector.
But both of us have asked you to verify fuel pressure under heavy load and I haven't seen a...
After the changes I recommenced you would need to go back over the tune.
Again I'd be wary of any map sensor that wasn't an OEM GM part.
I'd encourage you to look into EFIconnection.com This is a complicated wheel to re-invent and he's already done most of the hard part.
It's been a long time since I've seen one.. but a injector that drips will cause a hard start.
I don't know where we are at.. have you mechanically verified fuel pressure while trying to crank.

thank you..
For me I used to be pretty guarded on what I know. I mean almost all of it came at the expense of fighting some problem here at the shop.
But I am/was involved in another...
