Fuel pressure- 44.5
mbc- 1/2 turn short of all the way. It still only goes to 10 psi.

 

1/2 not enough turn more.... turn all the way down and try. dont forget the watch boost gauge.

go go go .....

 

I dunno, the timing got even worse on the last run and I really don't want a new motor.

 

no need to do 3rd gear red line to check your boost level. just try it in your first gear. it should easy jump to at least 15-20psi at 1st gear @ 5000rpm

 

I'm not driving it anymore untill I find out what's wrong. It maxed out the timing retard on the last run and I'm not risking the motor on another run.

I think you don't know what a MAF does........

Some cars run totally MAF LESS. I don't know if the UNI programming is written with some kind of safe mode, but my MAF failed... It gave Signal Too Low code (as good as dead). I then tried to run with the MAF unplugged and it ran exactly the same......

 

good luck man.. some pretty good insight there on AZ

 

Do you have logs to prove that "it ran exactly the same"????
A maf is used to determine the mass of the air entering the engine. The air mass information is necessary to calculate and deliver the correct fuel mass to the engine. If you take it out, you are going to run rich no matter what. The ecu doesnt see the signal so it makes sure to add more fuel because it isnt gauging the amount of air flowing which for all it knows could be a crap load of air and make you run lean.. Most ecu's know to add extra fuel if a MAF signal is non existant to prevent it from running lean.. Especially the ecu's that are tuned for forced air induction. Im sure without a maf you are running at least a little rich which in the long term will reduce the life of your cat/02 sensors, and short term hurt your fuel efficiancy.

You would need some one who is good with B5 to look in to it.
From what i see you have a programming problem.
Your A/F reads below 11 at low RPM under load - this is not right. As full load and 4K RPM you run low 11 AND pull timing due to knock.
This is not right. Get the software sorted out. I do not think this is hardware problem.
Who's chip do you run?

 

he is running unitronics software
