Commanded A/F problem

[driver456]

My comm. A/F is going down to 7.xx & 6.xx and I can't figure out why
.Its screwing me all up.Also in the tune Table B3617 is 1.000001 and also B3641 is 1.000001,I can't get rid of the last 1. Look at frame's 4703 to 4735 in the log....................Paul

Post the tune file as well....

Don't worry too much about the 0.000001 thing. A number of tables will default to an insignificant figure above or below a set minimum / maximum value for a cell. It's just the way the system works out values.

I'm still working on the tune,I just put new injector's in.Maybe somebody else can see something.I use the TPS VE table all the time.

Paulie, I looked very quickly at your files...

I see that possibly:
- B3617 and B3641 are each adding EQR 1.00 to the PE EQR (but there is another contribution because the EQR's don't add up),
- B3643 is ramping PE out too slowly.

Hey Joe,I shut off PE mode and ran it off comm. fuel and it works fine.I'll look at those 2 tables.Yea I figured something was up with B3643 because it was causing havoc on the parkway when I tried to drive back to normal if you know what I mean :),It wouldn't lean out for nothing for awhile and the car sputtering and black smoke coming out the exhaust.What should I set those table's at? B3617 & B3641.For now I need the car to idle & to go WOT for Saturday:).Thanks Joe.................Paul.......OK I guess they should be set to zero,Hmmmm I take it that was my problem.

Set those tables to the same as 2002 Corvette/Camaro, see www.holdencrazy.com for either file (basically those 2 tables contain zero at normal operating conditions, and non-zero otherwise).


I'm out of town so I don't have a pic handy.
