sounds like you would have to go to a custom O.S. or cut it in half like MNC5 explained

Ive been trying to tune this for a few weeks now and ive ran into a few things. Hope you guys can help me.
1. P0103 code for the MAF is showing in the DTC's. The SES light doesnt come on but the code is in the history and when i clear it, it pops backup right away. Is this giving me problems trying to tune in AutoVE? and how can i get it to now report?
2. When i returned to closed loop SD, when i would let off the gas it would go so lean that the wideband wouldnt read it, but when im in open loop SD, it would be very rich. any ideas?
3. When its in SDOL it reads the backup VE table, correct? does it only read the backup or blend with the main? when its in SDCL which table does it read?
thanks

1. What value do you have in C2903? If still stock, you may be exceeding the Hz value and tripping the DTC.
2. If DFCO is active in CL, it will shut off the fuel injectors at closed throttle and cause the lean ("pure" air) condition.
3. 98's - I feel for ya.

Who needs a MAP sensor on a supercharged LS6 anyway.
I have some logs but on my laptop, ill see if i can move some over, i have ALOT of them :-)
C2903 i took down, i dont remember the number, but i cut it down enough to get the car to get the same reading with only the ignition on as before the 2 bar.
I followed the AutoVE to return to CL, would that still have DFCO active?
ughhhh 98's :-( 2 of them
what about the P0103 code for the maf? should it even be reporting?
thanks

For C2903, review the MAF frequency in the log files and see if it exceeds the value in the table.
Two ways to check DFCO - reviewing the respective table values in the calibration and in a log, the commanded AFR will go lean, injector duty cycle & pulse width will drop, etc.

Im not using the MAF, im in SD. that wouldnt come into play then right?

You must have a MAF code set in order to get into SD. Won't run at all without the MAF if you set the code to not reported.Originally Posted by WicketMike

Gettin' the Groceries
I am finally getting my car back this weekend. Its been in the shop for almost 2 months getting an oil leak in the turbo fixed.
When i did have the car for a week, i was trying to tune it with AutoVE and just couldnt get it right in the lower areas. My white T/A which is n/a i have in SD mode and it runs perfect, but this turbo on the gold t/a, i just cant get it right.
So i am thinking about putting the maf back in and tuning it with that.
My question is, i have the 2 bar map sensor in there. Do i have to change anything so the 2 bar map will work if i dont go SD mode?
do i still have to change C6301 ?? or should leave that at stock and the 2 bar map will be ok while using the maf?
thanks!
