ZL1 Open Loop EQ Ratio Gas

Attachment 41990

I'm having difficulties sorting out my current ZL1 tune and I am not really sure where I am at. My question is this, every time I see this graph I can't help but think something isn't right. Any input is appreciated.

My car runs pretty well from about 4000 - 7000 RPM, unfortunately the lower loaded rpm range is where I am having issues.

Is that your stock EQ table? It looks nothing like mine.

Stock was this.

Something definitely doesn't look right.

I was looking at your 955 pulley header tune file and your table is the same as the stock table.

I was looking at your 955 pulley header tune file and your table is the same as the stock table.

I really see no need in changing it with my mods. Maybe with a cam it could use some tweaking.

return that table to stock, its a basic multiplier for fuel. no need to make changes to it.

what mods have been done to the ZL1 that you are tuning for?

Took the car for a mild drive yesterday and accelerating from a turn at the light, the car stumbled and I just happened to be scanning. The scan file I included has the stumble around frame 32900 if anyone has input it would be appreciated. Thanks.

What are the PE settings? You are at 120+kPa and still commanding stoich. Post your tune so we can take a look.

Thanks Ed

Can't really see anything except the PE Enable is 0 as well as the hysteresis. Knowing the way computers work with zero's....I would set the enable back to 300 rpm and the hysteresis to 30 and see if you trigger PE.

Thanks for spotting that. I was adjusting the MAP enable but never hyst or delay so I'm not sure when I did that. I'll look through my History. I have so many saved files for this that it really is getting pathetic. Backup drives, dropbox, cell phone... crazy.
