02020003 with 0411 will not go semi-open loop

[LS1_Dragster]

I replaced my computer in a 97 5.7 4L60E 4x4 with a 0411 computer.

I would like to run CLSD without MAF.

I would like the computer to use B3647 for the commanded AFR and not use PE mode.

I would like the computer to use the O2 values to run closed loop when commanded 14.68 from table B3647

Am I asking too much!! I did the same thing in my 71 firebird with a 454 and MPFI and it works perfect. I have spent 30 hours now trying to make my Yukon work and it just will not. I verified both Hi and Low wires from all 4 O2 sensors to the computer. The only real difference from the firebird to the yukon is the yukon uses the CPFI, the spider injector setup.

Can someone at EFILive help me figure this out?

The spider should make no difference.
Have you PM'd Paul or Ross? Maybe there's a 'glitch' in the software.

[LS1_Dragster]

I just updated the software and firmware praying that would fix it but it didn't!

It has to be a glitch, to have one work so well and the other not at all.....

I noticed that you have a similar setup, does yours go into semi-open loop?

[hquick]

From memory yes....but I've been running OLSD for a long time now. Next time I get a chance I'll try it (Truck is off the road having some 'cosmetics' done at present).
For the sake of reference, I've attached my current tune...incase anything stands out.

ok i went though same thing and was ready to kill my self after days of messing with it now i have done 30 cars with no problems 2 things i found where if the o2s are wired wrong or not any good it will not even try to go into closed loop,the other thing was i got mad and just took it for a drive mile up the road when all the peremiters where meet it went into simi closed loop i just wasnt getting tempature and time frames meet for it to work.it drove me crazy on like 3 cars now its no problem to figure out

Your good!

Story: 12 years ago a put a blower on the truck, took it to the track and put C114 in it. The guy said no problem running a little of leaded fuel, he was wrong. The truck ran terrible and smoked big time. I diluted the fuel on the way home and it ran much better. Once the fuel was used up and was running clean I replaced the O2's from checker auto. The truck has been parked ever since and only gets run a few times a year. Only has 13K miles on it!

I got under the truck and removed the O2 sensors which are 4 wire ones and got out the Chilton's. The wires 180 off! I put new O2's on and it works perfectly. BTW, I rewired the old ones and it still didn't work.

Thanks for the help.
