jgklim's JB4 Build
 
Hello JB4 community!

Very excited to be using this system. I've started this thread to document my journey/build with JB4.

I'll add to this thread content like photos, logs, and experiences as I go :happy

Introduction:

2018 Civic Sport CVT, I won't elaborate on the cosmetics for now

From Canada, B.C.: which means the weather is either like this...

or this...

Mar 2019

I got a package in the mail...

Didn't get any pics of the finished install, but...

The intake is great! Really improves the engine and turbo sounds!
Throttle is definitely more responsive...as I mash it repeatedly :burnrubber:

Awesome! Can't wait to check out your logs. :)

Idle values look like this
https://i.ibb.co/0QT2WMk/Screenshot-20190303-185022.jpg

Until I actually get some good pulls, here are some baselines for map 1:
1st - Idle, slightly warmed up
2nd - On and Off

If trim scaling is correct, idling at 35 is spot on at 0%, and in the 2nd log i'm dancing around 3-5% under load.

Question: Is there a parameter for CVT trans temperature?

Possibly It was 170 yuan for the cover when I bought it. I used superbuy.com as an agent and also purchased SEDAN seat covers to make the shipping more worthwhile. Cost me overall 450 yuan for both items, then duties :)

The sedan covers fit the rear bench, but not the back seat. It needs some trimming and adjustments

Intake updates
Having installed the intake first... I haven't gotten a chance to log with the stock intake.
https://i.ibb.co/hWpc65P/P-20190304-...v-HDR-On-1.jpg
It looks and sounds so good!

After about a week of using the intake and looking at logs, I think my trims1/trims2 are sitting a little high.

Correct me if I'm wrong:
If 25=0%, and 50=33%
Then each (1 trim unit) in the log is = (33%)/(delta25) = 1.32%

https://i.ibb.co/2qJX09S/Screenshot-...8-223422-1.jpg
Map 2 Pull: My trims2 being 32 or 33 (+7/+8) means I've got about +9.24% to +10.56%. Feels high :(

Is this something that should be adjusted? Looking at the new SI intake and the resulting trims (spot on!), I wonder if I've done something wrong to get the lean trims.
A Type R on these forums is also getting around 25 for trims.

Edit: I wonder if this is due to "up to 10%" ethanol in the Chevron 92 I filled with

Attached: Map 2 pull - gotta start logging in lower RPMs:happy

Map 2 and LTFT

Pull in Map 2 - Seeking check before Moving to Map 3!


https://i.ibb.co/sHRDxp9/Screenshot-20190312-195156.jpg

Following my previous inquiry - Found that after putting in some 94, trims went down :)
- Finding that when changes of fuel is detected, avg ign goes up. I suppose to adjust to new fuel
- It takes about a day or two (driving 30-50 km) to go back to 4.9

I figure this means half-filling tanks/filling more often means that the car has to adjust more often.
Ethanol does affect trims: making the car "think" to add more fuel:popcorn

Next question: When to stop adding boost (Upping maps)? How can we be "safe" with the CVT? Is it avg_ign? Any other indicators? What about long-term?

Hi I also have a Civic sport CVt 2017 , I知 getting my JB4 installed Monday
With new springs and intake , so did you get the answer with how much torque
Or boost the CVT can handle ??? I知 new to this and not sure I値l be making my own maps , will map 1,2 and ,3 be ok , with out blowing my CVY or turbo are the presets safe .

jgklim 08-11-2019 03:27 PM

I have no doubt the presets are safe. BMS also has a cvt which they developed with. That being said, I run map 3 most of the time and my experience has been positive. It's been about half a year, and no problems.
If you want to get supporting mods, an intercooler may help

Ricky going fast 08-11-2019 06:48 PM

Awesome! Thanks for the reply. Intercooler makes sense now that I think about it I知 in south Florida that would help a lot , think that will be next on my mod list Can稚 wait until the end of the day tomorrow
I知 making sure they are going to check my cars over all health it痴 a 2017
But have 57,000 miles on it all highway miles . Your hatch looks great
I have the white with black trim sport , I値l send you some pics and logs when I get the car back with it lowered Eibach Sportline Springs the k&n Intake also adding 20mm spacers to the rims and JB4 all tomorrow.Have a great week !

Terry @ BMS 08-11-2019 07:56 PM

Our CVT is still pulling hard with zero issues. We switch between 91 octane map1 and E30 map3. :)
