My email is shown in the envelope in the signature area.

I've also been documenting the bare bones steps of the Stage 1 phase here and now Stage 2 here.

That has a very different req boost profile from flyboys' logs.

Lets concentrate on a single file here. If you want to start another thread, do that...

I found that the last tweak to LDRXN had not been incorporated into his file.  Perhaps that is the culprit?  Aside from that all the other changes match up with what I have.

For flattening the boost curve, do you suggest raising ldrxn at the lower end to bring requested boost up?  I'm also thinking that holding a bit more boost mid to upper range is possible, near the top the injectors are close to maxing out so I'm fine with dropping down to around 10 psi in the 6000 rpm range, but it seems like that middle upper area could support a little more boost.

I think for the sake of safety we should leave a buffer of injector duty in the top end, even then the "fun" areas of driving tend to be the mid ranges.

one thing to remember though is tons of boost at low speed low RPM will strain the motor and ignition more. But I'm sure we can squeeze it a bit.

After further comparing bins I discovered a change that was made as a result of this discussion but did not get posted to the thread.

KFLDHBN (max requested PR) was modified as shown below.  On the left is the resultant table I'm now using, and to the right is the delta over stock.

You should request more load even earlier es k03 comes on boost early. Just a few 100rpm.

Earlier than 1600rpm?

Yes, or twiddle with the KFURL path (load->boost) to make req boost flat with respect to req load.

In any case, cleaning up IMAX is way more important I think..

I have yet to overlay your data with the compressor map, so I'd hate to make a guess at this point...

I think there's room to have a little more boost around the 3500-5500 rpm range.



This is my new proposed curve (black) versus the existing curve (red).

I would have max request at 1600-1700rpm.
He has it at 2000. Bit late imo.

Two data sets with the recent revisions incorporated.  Was a bit warmer today, around 82F at the time of logging versus mid 60's last time out.

Dataset 1

and

Dataset 2

what we're the ldrxn values you used to create the new curve? I would like to be on the same page value wise but i cant get exact values from the curve

Based on the injector DC from the last logs I'm going to pull back on the top end boost a little more.  New curve for LDRXN in black, last is the red line.  New values shown in the table.



Updated the DIMX values slightly as well, dropping them a bit.
