ign timing seems to be only be changed in 0.75 intervals so i usually don't use a % adjustment. I usually use the Ctrl U and Ctrl D (basically increasing or decreasing the selected areas by the number you set next to the + and - figure)

I only really mess with the aircharge in % and the rest i usually increase or decrease by certain amount each time.
I usually start off by messing with aircharge before anything. if you are limiting the output by not increasing the aircharge, you might not fully use the parameters you have changed.

also keep in mind, even if you have the fuel pump limit set to 88%, it can and will overshoot that and hit 100%. You will see the air charge get choppy because the car is trying to limit the fuel pump.

Yeah I read the notes on the fuel pump limit, hondata says it can and will go above that. Ignition values all came out in variables of 25 (25,50,75, 1) But i'll take that advice for when I try it again. Today is super hot so not the best day. Aircharge didn't look choppy, just lower than the base tune, fuel pump never went over 90%

I'm hoping its just the air charge %. But I was using the same table which comes with the 93 map. I wonder if it didn't work because I increased the torque targets but not the aircharge.

I haven't had time to really look into the logs but it would depend on other parameters but yeah the first thing i actually do is raise the aircharge.

let's say for example, you raised your torque targets to 600 and it required 270% air charge in order to hit that target. If your aircharge limit is set to 230%, even if you raised your torque target to 600, i don't think you would hit it because the aircharge would never hit 270 due to the limit.

I would ditch the pump limit, if you pump is peaking at spool up then drops off then that is fine you just don't want 100% the entire pull. Mine will hit 100 at spool then drop down half a second later. The reason I would not use the pump limit because it will pull from your aircharge tables to keep the pump happy so making changes to the aircharge table would be pointless with that enabled.

i agree. I am not a fan of that either. Just tune your aircharge accordingly and not use it. Makes your air charge all choppy too at times.

Ahhh, cool, thanks guys. I'll have to upload some new logs after I change my calibration. The new one I started is a little different than what I posted

Edit: increased my air charge variables and max turbo pressure table, disabled pump limit, but the car still makes less boost and peaks at 205% manifold pressure. Wasn't choppy in the data logs, just didn't give me anything. This is really getting frustrating. Wondering if I need to alter the fuel tables. In WOT the AF ratio is where it should be at 11.5-12.5 so I'm not sure that will do anything. I'm thinking of just giving up and doing a remote tune with innovative. Saturday is supposed to be much cooler, I need to force myself to wake up early so I can spend most of the day trying to tune.

Is there any way or trick to raise idle on the FK8 with FlashPro? With an upgraded RMM bumping the idle by even a mere 50-100 rpm would be a huge improvement comfortwise. I know there is no idle control per se in the current version of FlashPro but perhaps there is a trick, like changing timing or torque at idle speeds etc. that could influence idle speed by even a small degree?

AdamD19DFK8 · Aug 26, 2019

Have a couple weird things going on now. At WOT in 3rd or 4th gear the exhaust will pop 4-5 times while accelerating. Could that be an ignition timing issue or fuel running lean? Ignition is only advanced 1.5 degrees, I've had it higher before but figured to back it down. Looking at logs sometimes the fuel pump goes to 100 percent even after turbo spool up, but most times it's in the high 80s or low 90s.

Popping under wot can't be good for the car.

Another weird thing I noticed is that if I'm cruising around 80mph in 6th and I give it a lot of throttle the rpms will go up higher than what speed that should be at. Now it does this at 3.5-4k rpm, right when peak boost is ramping up, but I wouldn't think the wheels would spin or anything in 6th gear, it doesn't feel like they are

I don't believe this is possible. I know what you mean though. I had RMM on my 9th gen and just liek another 100 rpm would fix all the nvh when sitting at a light.

popping? are you misfiring?

rpm going up higher than what the speed should be sounds like a slipping clutch.

Has anyone gotten a custom tune with the new EGT setting enabled yet? I'm really curious to see how the dyno went for you.

boosted180sx · Aug 26, 2019

i still have a cat and limited by shitty quality fuel so i won't be touching that unfortunately.

I haven't seen any engine knock show up in logs ever. I looked over them when I first experienced the popping. The only thing I saw that wasn't good was the fuel pump was at 100% for a few seconds, I'm pretty sure that's when I heard the popping. My Max air charge value is 260% then tapers down afterwards.

The clutch still feels the same and there's no slipping at WOT when I'm in the right gear for it. I never launch my car or anything (well I did I'veonce and awhile ago) never smelled it
I have my torque targets at 590nm at 100% throttle although I'm pretty sure it doesn't make close to that. I thought hondata said they've been making 450ft/lbs on the stock clutch for over a year with no issues

boosted180sx · Aug 26, 2019

a misfire wouldn't show up as a engine knock so having no knock retard wouldn't really be an indication. You can try checking your spark plug gap and regap them.

well you are more likely to experience clutch slip in a higher gear than a lower gear so it makes sense you don't feel it right now if you are in the right gear.
Also, just because one car is fine, doesn't mean another one is. I know a guy who regularly tracks his car and is experiencing slight slip and he's nowhere near 450 ft lb.

Yeah I'll just stop giving a lot of gas in 6th gear lol. All my Google searches with popping at wide open throttle go to classic car forums with carb engines where the problem stems from lean fuel mixture which makes sense since when this fuel pump gets maxed out you can see the pressure drop by around 15-20%. I've had the aircharge and ignition timing higher and it didn't do it. I'm not sure how the fuel table parameters work at all, but I think adjusting lambda could help. I could also back the tourque targets back down to 575-580. I had it at 576 before +20% increase from the base map with no issue other than not feeling any stronger than 480

adjusting af ratio is easy on this ecu. It's as simple as inputting it w/e af ratio you want at a certain aircharge/rpm. Although, if you are already capped on the fuel pump, you'd just run out of fuel even faster by making it run more rich. best bet is to limit aircharge by changing the max aircharge or lowering your torque tables.

I appreciate all the help you've given me. I was thinking just back off the torque targets a little since 590 is close to the limit of 600.

As it is with air charge limit at 260% boost peaks at 28psi (in logs it reads it around 27.5) which I'm not sure if at that point it becomes inefficient

In general on 93 octane what would be a safe advance ignition value, at the moment it's at 1.5
