Here is my 90% map:



And this is my 94% map:


Notice the lack of difference??

Thanks Shiv for that confirmation.
That's what I thought, but then started to second guess myself (and my dyno results) when people pointed out the was no "0-100% status bar" changes after hitting "apply".

Good to know, Merry Christmas.

From what it looks like you can bump it up even more, your logs show that u haven't even reached you max 15 yet....Go 96% and see where that brings you....

4) Use "File" & "Open" on the newly saved map. The map should load / software should show the loading process (0-100%) at the bottom.
This is exactly how I change the map. Ensures it loads the map correctly.

If he wasn't seeing a big change in Boost after upping the % maybe he didn't let the ecu adapt?? When I upped my settings it took a bit before I could log increased boost.

Don't we adjust the boost (%-setting) and ignition is what adapts - not the boost?
How much more boost one should be able to log by an inrease of 2 percentages?

+1

And if you have the time, disconnect the negative battery terminal for an hour to reset the ECU and adapt from scratch.

The number you're changing is a percentage of maximum torque available. The ignition and methodology of how it's all controlled is really a question for Shiv or maybe Eugen.

Is it normal for some cars not to show a torque increase in line with a boost increase.

This could be possible. However that could mean now (many miles later) my car has adapted and I am running 16 psi.

This is getting technical.

Looks like the boost is exactly the same. Not too many explanations. If the ambient temp was clearly lower with the higher settings, the boost could be dialed down the same amount that the settings brought it up.

those graphs are different. Especially boost wise. Yeah maybe with some adapting it will change.. but it is holding a higher amount of boost longer. The nice part is the way it was tuned it is keeping very similar characteristics while boost is increased.

Re graphs, the peak boost seems to be the same 14.3 psi at both 90% and 94%, remains at the top plateau between 3500 and 5000 and begins to taper down at 5000. If we aim at the 15 psi, OP could increase the figures a lot, since 4% points did not affect the peak boost.

My concern is that I have not seen a boost increase as a resulting of raising the torque setting from 90% to 94%. I just wish I knew if this should be expected or points to something I am doing wrong.

I have very limited technical knowledge so would appreciate some advice form Shiv.

Why not try raising by another 4% to get more data points to find out the effect.

As long as the engine does not blow.

I did not see a big difference with boost levels between 94% with 91 octane and
100% with race gas. However, there was definitely more power.
