Just finished my COS tune and no start

[joecar]

B3647 does not provide sufficient fuel for a cold start...

you will have to use A0008 to add more fuel while cold (I don't remember anymore, but A0008 may have an inverse relationship).

[joecar]

Not related, but take note:

B3647/B3649 have been set up using wrong units (Lambda confused with EQR), correct this (as noted above);

B3616 is set to 90% which is too restrictive, you want PE to enable easier than this (look at 2002 F-car for example).

That log also shows it going into boost while cranking/trying to start

For B3647 can i just change that table where I would need more fuel or do I have to change A0008?

For B3647/B3649 I thought I changed it to EQR and then reentered the data. Ill double check.

"P1514 indicates that the throttle/airflow sanity tables are being exceeded (see the Engine Diagnostics folder of your tune file)."

I'm a little lost as to what tables control this and how to adjust them.

Thanks for pointing out these errors

I never noticed that...
C6301 is at 190 (I'm pretty sure thats right)
C6302 is set at 10 (not sure what it does or should be at)

Could one of those cause that? that will defiantly mess with things.

[yzriders182]

For P1514 would I raise the values for C6101?

I also have a gray cell in that table. What does that mean.

Sorry for all the newb questions.

[joecar]

Can you post a screenshot showing the gray cell...

No worries.

You also need to log throttle position and GM DYNCYLAIR DMA. You are also getting negative timing when cranking, I believe this is happening because of the numbers in your boost ve being calculated to airflow and there is negative timing in your spark tables at higher airflow.

For B3647 can i just change that table where I would need more fuel or do I have to change A0008?

B3647 does not have a temperature axis, so you have to play with A0008.

For B3647/B3649 I thought I changed it to EQR and then reentered the data. Ill double check.

Ah, my mistake, I was looking at your tune file in post #1 rather than post #28.

[yzriders182]

Just went to take a screen shot of the gray cell and it is no longer gray... going to raise the whole table for C6101 to see it that fixes the issue and going to throw more fuel at A0008.

Also want to find out why its seeing boost...
