Not sure exactly, but at 8:29 in the “21c” datalog, you go WOT in 4th gear at 1000rpm and 12 mph. Looks like you were decelerating on 4th gear, then went WOT for 3 seconds or so in 4th gear at 12mph. You stay in 4th for about 30 seconds, and then downshift into 2nd gear. No big deal really, just want to make sure we don't rack up and knocks like that is all.

Re: 2008 Si Sedan map suggestions please and thank you
I looked at the log. I have an idea of where that was on my drive. I had to merge over 4 lanes in a 70km/h after coming off a highway and take a sharp left into a parking lot. Some creative driving has to happen. I don't know why I would have went to 4th but obviously I did. Feel like a new driver after looking at the data. hah Maybe because I didn't have my morning coffee... I'll try to get a log or with the 22 revision. Do you suggest I do a 3rd gear pull?EFICU wrote: ↑Fri Jul 09, 2021 8:49 am

I remember watching a video that Nick did-dyno runs with multiple intakes. I recall he did a run with a similar intake to mine and that he quit after two runs because of the intake temperatures were getting too high and were affecting numbers... I can notice this in my car once the temps get up. I don't want to say it feels gutless but it is down on some oomf. Have you watched the video of him driving the K24 Porsche 997?

Re: 2008 Si Sedan map suggestions please and thank you
Yeah I figured it wasn't a normal thing for you. I just wanted to mention it since it recorded a knock while doing it. I've had guys that do have odd driving habits, but it's none of my business.afauser wrote: ↑Sat Jul 10, 2021 2:22 pm

The Takeda will give you warmer temps than say the Hybrid Racing or Skunk2 intake. Those two are the best performing ones I have worked with as far as performance and temperature control. Your Takeda has a plastic heat shield around it right? If so, once that plastic box gets how, it stays hot. Just like the OEM intake, the OEM box heat soaks really bad. Again, it's not my business what parts guys choose, I don't want to make anyone feel bad about the parts they choose. And yeah, once the temps get above 86*f, the ECU will begin to pull fuel and ignition to keep the car happy and knock free. If the car sits idle for a long time, in hot weather, the temps will rise no matter what intake you have. It's once you start moving that some intakes get the heat out, and some don't. Intake temps will never be cooler than the ambient temp outside, so if it's hot, the intake temps will be hot. Generally get the filter as far away from the header as you feel comfortable with. Either behind the headlight, or down in the bumper. Granted a lot of people are nervous about a true CAI behind the bumper, so I say get the filter as far away the header as you feel comfortable with.
I haven't seen his new Porsche video no.
Re: 2008 Si Sedan map suggestions please and thank you
I'll try to be a little more mindful about driving like that.
There is no shield so it just sucks up all that hot air. I purchased it after doing a bit of research(obviously not enough) and it was easy enough to find. A local shop had it in stock and the price was good. They may have made an oops on the price but I wasn't going to complain that it was too cheap... If I knew then what I know now I would have just spent the extra money and picked up a hybrid racing intake. Or K Tuned intake. I'm also thinking if there is a way I could slightly modify mine to be behind the headlight. Battery needs to be relocated and upper coolant hose needs to be changed. I find the intake temps consistently above 86 and lately with this heat upwards of 130. Its a bit ridiculous.

Re: 2008 Si Sedan map suggestions please and thank you
I would still consider upgrading to the hybrid racing CAI. I had the injen SRI and saw intake temps over 140*. The other advantage is 3000-4500 rpm's has a big power gains, right where we need it for daily driving. The hybrid racing has everything including a component that will save you from hydro lock. If you stay with your intake, cheaper way to help is wrap your stock header down to the cat and then replace the heatshield.

Re: 2008 Si Sedan map suggestions please and thank you
Thank you for your input. I will look into getting the Hybrid Racing intake at some point. I just feel bad doing that after all the work EFICU has done getting this map for my car to where it is now. 22 revisions so far then having to start over again. I have learnt a bit with this tuning but not sure if I'm comfortable to do it myself. From what I was reading that once you go to a larger intake pipe( 3" or 3.5") the MAF is basically not used(I hope I read that right) and uses the MAP for the tunes...MM082001 wrote: ↑Sat Jul 10, 2021 5:57 pm I would still consider upgrading to the hybrid racing CAI.

Recorded a couple logs yesterday. One in the morning and one in the evening. Morning log I was chasing down a BRZ, the fun part is around 1:20... I'm sure he was full pin and I had to let up a bit because I was right behind and catching up. In the evening I attempted a 3rd gear pull but ran out of real estate and had to get on the brakes. The log is not very long though. The car feels great in the mornings when the temperature is lower. Thank you

Re: 2008 Si Sedan map suggestions please and thank you
Yeah the HR intake would help. Your car is MAP tuned (speed density), so you can move to the HR intake with no issues. It wouldn't take too much effort to clean up the tune for it. We have done the bulk of the work, the intake would need some simple fueling upgrade and perhaps some small ignition changes. Nothing that would require more than probably 5 or 6 revisions so we can get it all dialed.afauser wrote: ↑Thu Jul 15, 2021 9:55 pm Thank you for your input.

The datalogs look really good. No knock, fueling is nice and consistent which is good. Make some more datalog next week just so we can verify it's all good and we should be good to go.
Re: 2008 Si Sedan map suggestions please and thank you
So I went ahead and ordered the HR intake.. Should be here next week.
With your experience in the land of tuning do you recommend I remove the coolant hoses going to the throttle body? And what about the cold idle valve on the intake? Leave it on or disconnect it? Thanks

Re: 2008 Si Sedan map suggestions please and thank you
Nice. I think the HR will be a nice addition for you. We'll make the adjustments for it once you get it on to take advantage of it. We'll probably lock you on the 15, 30, 40, and maybe the 45 again for one revision each just to dial each table. The HR will bring in more air than you do now, so we'll need to get it right so we can take advantage of it.afauser wrote: ↑Thu Jul 22, 2021 8:47 pm So I went ahead and ordered the HR intake..

If warm climate areas like here in California, I would say it doesn't hurt to take them off. I have them bypassed on my TSX because it never gets cold enough to freeze the TB here. People have their opinion on why exactly the coolant hoses go to it, but in your cold months it would probably be good to have it on there so it would unfreeze the TB if it were to. Not sure how cold it gets where you are, but if it gets really cold in the winter months I would probably recommend leaving it. Don't touch anything on the mani, leave everything as it is, but if you want to bypass the coolant lines you can. The TB gets hot no matter what, so how much cooler it might be with them bypasses who knows.
Re: 2008 Si Sedan map suggestions please and thank you
It gets cold here in the winter I want to say average -15C to -20C. -30C to -40C last winter for a few days during a cold snap. I will leave the coolant hoses connected to the TB. I used a infrared temperature gun and was amused to see that the TB was hotter than the intake manifold. I was thinking that the intake would have been hotter being that it is attached to the head and block. But I guess it makes sense because the TB does have the coolant lines running though it.EFICU wrote: ↑Thu Jul 22, 2021 11:54 pm

I'm glad I looked into the HR intake again. The installation of it seems easier than the K-Tuned intake. HR utilizes holes that are already available and the K Tuned requires some drilling. I like less work. XoD

Re: 2008 Si Sedan map suggestions please and thank you
Yeah I would leave them connected then. I don't remember how they are setup on an 8th gen, but you could bypass them in the warm months and then connect them in the winter. TSXs are really easy to bypass, one hose basically goes right to the other hoses outlet. Makes me think some countries must not have these hoses, since one of my hoses that goes to my TB will also reach perfectly to the other hoses outlet from the block. Making the bypass way too easy. I think the TB might get hotter because the material is more dense. But I am no thermal engineer, haha.afauser wrote: ↑Fri Jul 23, 2021 12:05 pmIt gets cold here in the winter I want to say average -15C to -20C. -30C to -40C last winter for a few days during a cold snap.

I don't like drilling either, so it sounds like you made the right choice. That or the Skunk2, both the Hybrid and S2 seem to perform very well from my experience.
Re: 2008 Si Sedan map suggestions please and thank you
Got the intake. Will be installed tonight. Should I do a run on the current map then upload?

Re: 2008 Si Sedan map suggestions please and thank you
Nice. Yeah take it for a 20-30 minute datalog with one WOT pull in third gear like we have been doing. Only do one WOT pull until we look over the datalog and build a plan for the next step.
Re: 2008 Si Sedan map suggestions please and thank you
I have 2 logs with about 30 mins of driving between the two. First one has the WOT pull. Looks like it leans out a bit in the 4000 to 6000 rpm range.
Second log I was stuck in a bit of traffic. I noticed that the intake temp is easily 10-15 degrees cooler now that the previous intake. I also noticed that if the temperature does creep up a bit while driving slow or stopped, once I start moving with a bit more throttle the intake temperature does drop a few degrees much much faster than the old intake. Which all makes sense due to the placement of the intake pipe.
I do need to play around with the intake/filter a bit as it is pressing against the fender liner which is causing some rubbing/contact with the tire on tighter right turns. Just hope there is enough give to it...

Re: 2008 Si Sedan map suggestions please and thank you
Yeah it definitely changed a lot of things. Idle leaned out, midrange leaned out as you noted. You're also running on the WOT column 9 a lot more which means it freed up some restriction in the system which is good, basically bringing in some more air. You were running on column 8 exclusively with the old intake which is normal for higher elevation.
Based on what I see, I would probably recommend we sort of start over in a way. Go back and make a new 0* cam calibration and run through the cam angle maps again to clean them up. Then we can see where it likes what and get it all dialed. If you don't want to take that much time to do that, we can clean it up as is. So it's totally up to you, just let me know and we'll go from there.
