Go look at the PP3 tune in the repository. That is a solid starting point for a bolt-on Coyote.

So lowering the table makes it leaner?

After more reading it seems I need to adjust the cranking fuel table also, but not sure which way to go on that table.

Lately I've been having a problem starting the car after it's been sitting for a while. Cold starts are fine, hot starts after just shutting the engine down are fine, but if I let the car sit for 30...

Do you have the tune?

Sounds like you have too much timing variation in those cells and the computer can't hold a steady continuous timing thus it's surging.

The intake sits on top of the radiator and the sensor is in a silicone tube in between the radiator and throttle body. So it gets heated up real quickly when sitting still.

I haven't had a chance to mess with the bias table yet as I'm away for the long weekend, but I plan to try upping it soon and see if that does anything.

Yes car is tuned in speed density. So then basically it's always 50/50.

Have you ever messed with this bias? What is it really for?

Ok cool, I'll try that.

I assume only need to worry about the 0mph values. But what is the other reading (LB/H)...is that in regards to fuel flow?

My table starts out at 0.5 at 0 LB/H, then as...

Well I was able to verify a few things over the past few weeks. First, the battery is ok so that's not the issue. Second, I was getting a security code which basically disabled the pump, so I was...

Thanks. So I can in fact change the idle characteristics of say neutral vs. in gear.

Do you happen to know when the PCM shitches from the neutral values to the 1st gear values for example? Is it...

Does anyone know when exactly each of the different rows and columns are being referenced in an E40 PCM with an M6 transmission?

I'm looking at the min airflow table under idle and it's got all...

So I did all that and didn't really seem to do anything. Here's a log of what happened this morning. You can see how long it cranks for with 0rpm and then it finally catches and goes.

I see the...

So cut the VE airflow at 400, put the cranking VE to 80, lower cranking spark, lower min airflow and lower startup airflow?

What about the cranking FA mult stage 1 table...I have that almost...

58609Yeah here's the stock tune for the 2006 GTO E40.

And the intake is a FAST 102 along with the cam and heads. I do think that the min airflow is a bit high as the idle RPM is about 50-100...

Both really.

It's not, has 0* of overlap at 0.050 so idles pretty smoothly otherwise.

Thanks. What about for warm starts...do the same if it has trouble cranking?

This is the cranking spark table, which I've added 3* across the board from another suggestion. So you're saying it actually likes less timing and I should actually lower it to single digits?
...

Yes, I have a cam signal and it drives and idles perfectly fine otherwise. Just has a hard time cranking it seems.

I recently installed a fresh LS2 engine, new top end, cam etc. along with some LS3 injectors. This topend was on my previous stock engine and it worked fine, but lately it seems to have a real hard...

Hmm thanks, I'll search for that.

Going back to making sure there are no big jumps between cells, should I worry more about left and right (as in between different RPM) or up and down (as in...

Yeah that's what I noticed about the spark. I'm trying to even out the timing table so that there aren't huge swings between cells.

About disabling spark smoothing...isn't that exactly the...

I'm getting some pretty bad surging at light throttle between 1200 and 1800rpm mainly in first gear. Any other gear at those RPMs is pretty smooth.

It's a 2006 E40 PCM, 6.0 with heads, cam,...

Ah ok thanks. It seems most are not editable, however the ones that are don't give me the option for *more* resolution, just different. So while I can change the values in each of the 32 columns, I...
