(I'm not too worried about that, though, because I had thought I'd set the safety to 24.5, and even with it set at 28.4, the highest I hit was 24.1.)

Looks like there is quite a few maps already - Is it correct to say that the trend of the map is Map1 is least aggressive tune and the higher number, the more aggressive tune?

Yessir.

0 = stock
1-3 = a bit over stock, make sure and use good fuel.
4-5 = blend your gas with E85 and know what you're doing.
6 = Custom map; disregard for now.
7 = Full send, haha. Probably best to just forget this one is there for now.
8 = Valet map. (Kills boost, kinda like driving my wife's non-turbo 1.5L Honda Fit)

That poor bastard, haha. I didn't even realize we were racing at first, but he quickly learned.

However... I notice in my logs that the boost safety is still 28.4. I know I changed this. But, when I did I wasn't connected to the JB4. Do these settings only properly save/change when actively connected?
I'd probably kick the map down for now until we can evaluate the higher boost levels. But, the log indicates everything is fine here. Boost, timing, and AFR all in check.

Due to the interface change over you may have to hit save a couple times to get it to save the updated boost safety trigger the first go around.

I've been on it since Saturday running great, but if you think I should back it off for now I will for sure. Think 5's good?

5 seems like a better bet short term, to keep boost around 22psi or less.

It's interesting that your KC almost never moves.. I get a lot of movement on our CVT even with ~E30. We'll have to look at more manual trans vs. CVT logs to evaluate.

This is just pure speculation, but I wonder if perhaps the non-Si cars have a higher sensitivity to knock? The Si has forged rods and some other parts that are a bit beefier, so maybe they make the knock sensor less rigid since the engine itself is more stout?

Could the temperature difference also have anything to do with it? If I'm running cooler, wouldn't I be slightly less susceptible to knock?

Both could be factors. We need more customer logs from different climates and fuels to compare with.

It should be warmer and Sunny this weekend on Sunday... I'll be sure and get logs with the warmer temps and see if that makes a difference.

Oh, and actually speaking of temps... since Ando's car is using a SRI and I'm running a proper CAI, our intake temps are probably way different, and I know high temps will cause these motors to pull timing to avoid issues.

I'd wager temps are a big difference.

Did some pulls in 7 for **** and giggles in the new firmware, and it kicked me to Map 0.

Dropped it down to 5, same thing.

Went to 4 and I'm good.

I think the MAP temps (Trans Temp in the app) aren't right. The IAT I think are pretty on, but the MAP ones I've seen in the last few days either below ambient (which shouldn't be possible) or WAY above (and when I say "way" mean way; before I left for these pulls it was saying my MAF intake temp was like 90-something degrees and it is like 57 degrees outside... I popped my hood and felt the MAF sensor and the intake tubing and there was no way it was 90+).

Could incorrect temps trigger the safety map?

Give 'em a look over and let me know what's up.

Yes if you set the boost safety to 22psi then it's going to exceed that on most of the higher maps.

Logs overall look OK to me.

On MAF temp seems reasonable in the logs. The sensor itself will heat soak sometimes internally. What intake is on the car again?

Was able to hit the dyno today with a 2018 Honda Civic TypeR for a little JB4 tuning. Test car is 100% stock with around 12k miles on it. Running 91 octane pump gas.

After a lot of tuning the best results were found running around 4psi over stock down low and around 3psi over stock up top. Gains on map1 were around 30whp and 50wtq.

We played around with higher boost levels and while power went up a bit the data showed the engine wasn't as happy. Next time we'll try with some better fans and maybe an intake on it to see if we can push power up. But overall happy with the gains. Car feels like a rocket compared to our Civic Sport CVT.

We've split apart the JB4 firmware for the typeR and I'll be posting that separately in the first post shortly along with a typeR specific map guide.

I'm an idiot, it even says that in the firmware notes, haha derp.

Intake is a modified Mishimoto. It has the silicon tube from the turbo inlet pipe to the MAF housing, then instead of the filter surrounded by a heat shield, I ran a tube covered in heat tape down and placed the filter behind the fake grill/foglight (where PRL and Injen place theirs). And, on the fake grill, I've cut out part of the honeycomb to mimic the open holes on the passenger side, so it's getting direct air straight from the front of the car. Perhaps I need to wrap the MAF housing itself with some gold tape to further help intake temps.

Don't forget the Si and crv both also run less compression to allow for more boost vs the regular civic turbo. This will make it slightly less susceptible to knock once fueled right.

That would make a huge differences, yes. Let's get more Si and non-Si logs posted on various fuels and climates so we can draw firmer conclusions.

As soon as I get the rhd cable I'll start making logs, hot climate 95 ron fuel.

This is from the posted engine specs honda japan.

the standard civic is 10.6:1 compression ratio, 16.5 max boost

Civic si compression 10.3:1 ratio, 20.5 max boost

Crv compression 10.3:1 ratio, 18.5 max boost ( same engine mostly as the Si but tuned differently ).

Oh wow, I knew the non-Si motor made less boost, but I didn't realize it was that big of a difference; I figured they made at least 18.

This absolutely plays into why I've been able to run Map 7 and hit ~24 PSI without my knock going insane.

Difference between static compression isn't much.
CR-V/Si turbos do have a higher flowing turbine. The better flowing turbine and being tuned for premium is what gives the Si the advantage.

We have a local Si we'll be dyno testing in a week or two, to better evaluate the differences.
