Not sure of the exact details. I was looking at similair setups and doing compares. Used pcs of other tunes until I got desired results. So at some point I copied that min spark table into mine.
...

Thanks I will do that. The spark tables were low because we were trying to get the timing to change and couldn't get it to move. I didn't set the retard table I copied from another tune.

I had...

Also why would this table only take affect at wot?

Now that makes sense, what should I have in that table, should I go back to stock settings??

Here is current tune and log file.

Come on now I maybe dumb but not that dumb. Even reread the pcm and it had the changes to the tables just didn't change anything when the scanner read the timing.

Also knock retartd never moved,...

I was at a dyno today doing some tuning and we would change the Main Spark Advance tables under low and high octane. We would then do a pull and every time the timing once I was at wot would go to...

I have a 1998 Vette with lots of mods, Going to tuner soon, but wanted to put some milage on before I go. Don't want to hurt anything. Thanks J

Well its pinned correct if the info I found is right

From LS1 harnes;

Pin letters on ls2 tb/oem wire colors

What are you saying its causing?? The surging or high idle? The TPS jumping around??

The harness looks good, I pulled on wires to make sure nothing was loose. It is a Casper Harness.

Why in...

Not much change on tune 5, did does seem to surge less (not moving 300-400 rpm now moving maybe 100 at most).

I've included the new scan

Checked tb it has no holes. The wire colors match up on the harness I got from LS1speed.com not sure the pin sequence on the tb itself. I will do some research.

The tb was ported by Total Engine...

Here is idle log tune 4

I have a brand new LS2 90mm tb, so unless it comes from factory with hole there shouldn't be any.

Hey Russ,

Tune 3 and 4 are keeping the idle even higher around 1800-2000

I have attached a scan for both.

Thanks J

CR is around 11 to 11.25 shaved heads to 60cc.
Stock metal gasket .054
Stat is a 160.

Also running ngk tr6 spark plugs, because of higher cr and should be pushing over 550hp on motor.

As...

Maybe a dumb question, But you did check all fuses. How about wiring anything melt??

Seems weird that everthing in there seems to work except pulsing injectors.

Just trying to help. Good Luck

Thanks for your time. :)

I have attached stock file for m6

Having idle surge and idle wants to settle around 1400 when hot.

I have added a lot of mods and have an appointmnet with tuner, but wanted to get a few miles on before I go in.

Any help would...

Thanks:)

Does anyone have a stock file they will share? :pray:

Need a 98 vette with manual trams. Repository only had autos.

Thanks J
