That's not even close to any table I can find, nor does it progress like anything I can find?
Post up your bin file and let me take a look at it.

I'll find time to look at them later but how'd it do? Did voltage come up? Did knock go down?

Volts are up, first drive same knock, wot drive same knock, ADJ after log is better. but still alot of knock at far less rpm's Im on the right track i think. I will post the new bin of pulling timing. Please let me know if i pulled to much... Do you think i should add some more to the % table?
THis is the newest bins for pulling timing, on the way to the car to tune the computer. I will let you know how it does.

Well is it real knock? If you pull a bunch of timing does it go away? If not could be false knock.
Got good fresh fuel? I've been stung so many times by guys that got there car running and didn't tell me it was year old fuel...

I'll catch up and try to help...
But here's one thing tying me up today, my kids truck with the new TBI conversion that tuned out perfectly a week ago has been running worse each day. So kid says "I don't know" so we pull it in shop to find out whats going wrong... this filter was one week old. Happens all the time on conversions in old cars, new fuel system keeps gas flowing and sediment stired up and this is another reason you always run a filter before the inline pump.
So you say you made need a filter ay?

I looked at your last log in Datamaster under a few cars and all the same but what is it? Camaro, Caprice? Looks like Auto...
Your WOT voltage did improve but at 5900 RPM your down to 12.8 volts and from 850 RPM to 3500 RPM your at 13.4-5. So maybe a belt slipping too?
Went back and read first few posts and you got a cam and 1.6 rockers, regular driving your rich, BLM should be closer to 128 and your hitting rock bottom at 108 so you need to adjust the VE tables for fuel. Is your pressure stock?
But WOT your hitting 90% Injector Duty Cycle in spots and O2 reading left stays in .9xx but right drops to .2xx and it shouldn't. Injector duty cycle should not go beyond 85% tops! Seems to be an area getting some knock too. Your running out of fuel. Or injectors are going static?
Watch your data log slow around Rec# 70 to 75 and 460. Actually watch the whole thing slow and study it. When the boxs change color it's an alarm, you can also click on View Knock Retard for another KR window. Looks like all real knock to me.

ARGH! im changing the filter in a just a minute. The tank was very clean, im thinking the pump or filter... I watched the injectors and they max out quick. This car is almost stock, that should not be happening.. I am watching the data very slowly and taking notes. We will get this worked out. At least its real knock.. Thanks for all the help.
Since you recently did everything but filter I would change it as it's easy. Partially clogged would explain fuel supply issue at high demand.

Filter did not help. I think my pump is bad. Turn the key on (but do not start it) and the pressure goes up, but bleeds off quick.. Like when you have a bad diaphragm in the FPR. The pump was used, and set for a couple years in storage. Might be toast.

That's to bad but at least you found it before you leaned out your motor to a puddle...
