235whp or thereabouts
0.32" currently on BKR6E plugs.

Either the block is fucked, or I need colder plugs or turn some MSPNP corrections off (AE, CLT/AIT corrections and all other stuff). Cuz I see AE active while at 100%TPS in boost.

Take the gap down to .025" and see if it changes.

your TPSdot threshold is way too low.

your entire log is also interesting, the entire log shows your gammae at 93-95%, so your MS is pretty much always running 7-5% less fuel than your VE fuel table at all times after warmup. looks like it's all Gair related, so due to air temps.


nothing in your log really shows anything that would cause a weird lack of power.

Thanks for looking into this.

I've already reverted my TPSdot to something more sane and need to test that yet.

I've turned off CLT/AIT fuel and ignition adjustments, that helped a little at most.

I found an issue with Gammae at the point that my drop out seems to occur. I don't now what this is, or why it reacts the same way at 6k as the throttle being lifted after the run.

I've added my msq for those interested. You may have to select the Gammae from drop down menu

It's true that right around 6krpm is see funky Gego, Gair or Gammaae fluctuations. Not huge, but still... turning that stuff off and testing again.

Heres a better log of it happening on mine. Looking at Gammae something is happening around this rpm. Sorry about adding my msq instead of my logs. oops.

Spooky:

Let me know if you want me to scram from your thread.

gammae just shows the entire amount of enrichments, it doesnt tell you what is add/subtracting, only that it is occurring. it could be o2, Air temp, warm-up, baro, etc.


when i look at your first log I see a few things battling for fuel. your Gair is dipping to 90%, so as temperatures increase in boost you are trying to pull more and more fuel. for some reason your baro corrections are locked at 104%, so you are constantly trying to add 3% on top of your VE table. Your gwarm is locked at 113%, so after you hit 160% you are still adding 13% more fuel.

so when you average 103, 113, 91%, etc. you end up with your value of 105% in that log.

You have too many enrichments battling it out.

look at your warmup enrichment curve. at 160*F it's at 113%...so after the car warsm up, your telling it to add an additional 13% to your fueling algorithm. make that cell 100%, you probably will have to increase the VE table 13% throughout.

the Gair is pulling for based on the built-in ideal gas law code. It's fairly aggresive after 90*F, so that's why you see the Gair drop down so much. I like to reduce the MAT correction value to make the built in corrections less aggressive, and I also use the MAT correction table to sorta negate the subtract of fuel altogether. This will also help warm starts.

your baro corrections table should be zeroed out, right now it's showing 1% increase across.



now.

as for the gammae dips, if you look at the indicators in MLV, you see at every dip the bit 8 goes Y. that's MAPdot decel. so you might need to go to general lags, and decrease the MAP lag value to "smooth" your MAP readings so the decel doesn't get triggered in boost. in acceleration wizard you can also increase the mapdot threshold.


try all that and may the force be with you.

WOW

I'm asking for a little spoon feeding here...... What's a reasonable value for the MAT% and MAP avg lag factor???

Since I won't be testing in on a dyno I will have to do some logging. It wasn't always noticeable becuase of how fast it happened so I amy not be able to get it perfect. I fixed the accel enrichment, increased the fuel cells by 13% and set a 0% correction for baro on the baro correction table.

i tuned my AIT corrections by monitoring my AFRs while sitting at idle and letting it heatsoak.

my table looks like this:

40 5%
50 0%
78 0%
83 2%
101 8%
120 16%

Do I need to adjust the MAP kpa to include the max boosted kpa???

turn it to 1000 and see what happens. i dunno why it's even using mapdot when technically it's disabled, i was having this same issue.

What about the MAT correction scaling factor. I don't see the page where the AIT table exists. I'm diving into areas of tunerstudio that were previously uncharted by me.

Are you talking about "non-linear MAT correction"

I've found the scaling factor pV=nRT at 100% Just not sure how much it should be reduced.

I haven't seen this question asked, and it seems important.

Do the enrichment graphs time out???

Do you have to set the last value of after start enrichment , warmup enrichment, etc to zero?

I always thought that once it was above the last set value it turned itself off.

After start enrichment terminates after a set number of user defined cycles correct?
