Looks like a vacuum leak.

First, make sure CylAir is correct by doing what I mentioned.

There's always the option of rescaling the tune, but if you're at something like 1.36g I wouldn't do it. An alternative is to use...

What you're saying makes complete sense now. Know what I was doing wrong? When I looked at the SPA graph I always thought integral. No, it's literally a point lol. The Y-axis isn't...

Setup the injector data correctly then redo VE. Right now CylAir isn't reporting accurately. Deka 60's flow around 73lb/hr@4bar not 52.5lb/hr. Don't forget the other tables.

Probably one of your browser extensions. You should be seeing this:

Anyway, here's the same tune attached inline so that you can click it like the others.

Without being able to see the tune to make sure everything is setup right, I'd have to say turn off Spark>Advance>AC Bump Tq Spark.

What lol? Was gonna say all I did was adjust the complex temp model. That wouldn't make AFR that far off.

I just opened it. Idk why it won't work for you.

I dunno man. This is about the last thing I can think to do.

This is your tune setup for Deka 80 at 43.5psi if you'd like.

Do you have similarly poor VE tuning?

It'd be cheaper to select a cam that would work with PAC 1219's. The very slight difference in power will be made up by revving higher, and the engine will last a hell of a lot longer.

Mr. Banish, I'd like to be clear with you and everyone reading. I'm not trying to shit on your work. Actually, I think you do stellar work. The fact that you do injector characterization for...

Well he's going to have to figure something out. Without roller tips that cam is going to wear out the valve guides pretty quickly, especially those bronze ones. Maybe longevity is taking a back...

Oh that doesn't surprise me one bit. Thing is thousands of people have also tuned with that data. I guess what I'm getting at is you claim improvements over other's work and even your own previous...

Alright well it's responding to fueling commands. That's what I wanted to check. Rough adjustment to VE here.

Try this real quick.

Check spring install height as well. Shim as needed.

The errors become increasingly more important because as pulsewidth decreases the non-linear region comprises a greater proportion of total fuel delivery.

I'm not offended at all. I'm glad you...

Offset the weight of the roller tips with titanium retainers. Check wipe pattern with a permanent marker.

I'll second the Denso recommendation.

Right. MAP is decreasing. That tells me and edcmat that something in the the intake can't keep up. The decreasing MAF part points toward valve control.



You really need to be careful. ...

Thank you. I spoke to the error at low PW above. I also spoke about how the only response to my questions is the one you just gave - people are able to tune with it. Andy at AACorvette said the...

Are you sure the initial spark timing is correct? I'm having to give it a lot of advance at idle, and that's what you're seeing as improvement. How did you go about integrating the optispark with...

Yeah it's hard to tell. Looks like a normal shift except for MAF falling off. I'm leaning valve float. What's the P/N on the springs?

Sure, some component of the intake tract can't keep up with...
