Help with log

Here is my log having a issue at knock when under boost. Towards the end is where the knock is when doing a pull.

How are you running 550cc injectors without adjusting anything in regards to fuel (global % and deadtime, for example)???

Take note of your DTC code that's being thrown. Not an important one, but an issue none the less.

Post back an idle log once you have done all that plus a boost leak test.

Everything is getting signal from the safc for now. I don't know how to take out the safc so I will wait till shop does it and tune it but in the mean time everytime I have to pass someone or go up a hill I hit that boost it spools so fast but I always get about that same amount of knock. That is only about 8psi of boost. Do I need add more fuel?

It looks like you are running an estimated 9:1 AFR, so you'd need to take fuel out (might be rich knock).

Can you zero out the SAFC until you have the opportunity for someone to take it out? This way all the controlling is done via ECMlink.

havent got wideband signal to ecu yet but the wideband read 11:1ish at boost. But your right I will try lean it out see if I get less knock.

I really can't tell you what to do then. It seems like the car is still "tuned" using the SAFC but you're just logging some various values with link.

I zeroed out the safc and set globals -18.4 and 180 deadtime. Here is the log.

You are running waaaay too much timing. The ecu is pulling up to 9 degrees of timing retard through that pull. Thats 27 counts of knock. Your motor cant survive that for very long.

weird I have been driving with that tune for awhile.. I guess I'll take it in ASAP to get tuned it's still pulling fuel trim under boost from safc so it might not be reading 100% correct on link.
