I can’t comment on how BLMs behave in OBD2. Probably best to ask in a thread about obd2 or start a new thread.

BLMs are learned fueling corrections that the Ecu stores in different “cells” (depending on current engine parameters) for closed loop correction of A\F. When you are in a cell it’s applied the...

No problem. Back in a third gen after a few years. Haven't been on in quite a while. Seems this place has slowed down.

Yes, timing may be added. But only until you get kr. Then back off a bit.

15-16 at wot or what?

I no longer come to these sites, so I probably won't respond again.

I probably will never...

Sold some stuff. Current list is Current.

Still have stuff

That's all you need.

The biggest thing is going to be your timing vs. map vs rpm table. Add timing in the associated tables until knock is detected, then back it off. Start at lower rpms.

You have not said what you've tried.

These two tables:

%change to afr @ WOT vs coolant temp
%change to afr @ WOT vs RPM

Have you changed either of these? You can change it via these or...

You may not need ported heads to reach those rwhp numbers. Cam only can definitely do it, but with stock manifolds, it will take some work.

Cat tuning? You mean tunercats? I have no experience with tunercats. But they are probably the most popular lt1 tuning program. You can tune for free with tunerpro rt. Check out Grobs writeup in...

I didn't see if this was an m6 or a4? An A4 you'll need a hell of a build with stock manifolds to hit your 350whp mark. M6 will need mild heads and cam with stock manifolds. Basically get some...

Read my tuning guide. If it's too crazy for you, buy the cable pull your tune off the PCM email it to me an I can change the settings for you and email it back for you to upload.

OBD1 or 2? OBD1 needs to be tuned. OBD2 you have a problem.

uhhhh...

Yes

If that's a real anniversary car, I will stomp on your testicles if you part it out.

Only way to tell if the timing is even giving you more power is to dyno it. At a certain point more timing is pointless.

And where you are is good.

That's the last thing you should be thinking about. Start with the basics. When you are good with the basics the complex things will be easy.

What the hell is wrong with his tranny?

Did you read my write up? It's "the ultimate blah blah blah" about 4 threads down.

A datalog would help. We could see if it's pulling timing, flooding etc. Can't tell for sure.

Raise the enable rpm to 4400 or so. Leave the diagnostic on, I'd say. Also raise your fuel limiter and possibly lower the shift.
