Thank you for this. I've been having this issue with my jdm xt but I couldn't find any information about it. Then a few minutes ago I see this video recommended to me
Adjust the maps on my 2017 Levorg and it fixed it. I adjusted 3 other maps that were the same. Thank! Just need to fix the rough idle at cold start now.
Looking forward to this - my Forester STI does the same - only whilst gently pulling out of the end of the road, having been left overnight so stone cold.
Ah bugger. I forgot to mention this when you popped down . mine kangaroos for literally 5 seconds from cold then clears . have to remember that on our next map session.
Yeah..warmup table in jdm is pretty lean as like they want to give time on slightly longer cold idle clearing snows on the car before start moving (in japan obviously) Meanwhile in malaysia we didnt have this issue from hotter climate... Apart if we were staying overnight on top of cold mountain with sub 20 degreeC temp in cold heavy rain morning...
This probably because japan imported cars are run on a 99 ron fuel base as opposed the uk 95 ron. High Ron protects against knock, so they are probably tuned leaner than uk cars.
My UK blob STI likes to stall when cold, especially during the colder months. Can a lightened flywheel cause this, and can the map be adjusted to compensate? Or should I look elsewhere for the problem?
@@davidwills4898 Yeah def a light flywheel can cause that along with lighter pulleys. Raising the idle rpm normally gives a little more time for the ecu to react 👍
Thanks for the video, I edited the maps. I'll try it in the morning to see if it helps. I have a 2017 Levorg with the 2.0 Dit. Apparently there is an issue with JDM model with rough idle when the car warming up.. Any idea how to correct the issue. Sounds like maybe too much fuel..

The rain in the background and your narration make this one tranquil video to watch.
Its like David Attenborough for tuners! LoL!! 🥰
Plus a hangover and even more hoarse voice from the football win last night 😂

Cool 😎
The lambda sensor on jdms are slow to wake up so it could be that it's running a little lean until it does ..check with a wideband 👍
@@racedynamix Ok. I will have to see if I can find one.
@@racedynamix which map would I add fuel to? There are 4 warm-up enrich maps. Enrich homogen TGV open and closed and Stratified TGV open and closed.

exactly... Easy fix for your chosen mapper 👍
I've been looking forward to this one...
Hopefully it doesnt disappoint. :)
@@racedynamix Great results. Hopefully you'll be able to apply this to my Cross Sports when I get it mapped.
Feel great after smoothing out the maps.
you did it in yours ?
@@racedynamix yes
Nicework Dunc! Wish everything was that simple to fix lol
Same mate. I was expecting to do a few mornings of this one 😂 Is your spare room ready yet ? 😁
@racedynamix haha absolutely, new bed all set up for visitors! More than welcome any time 🤙

yeah no probs Andy 👌

JDM spec c, same problem (along with the GR stumble) I thought these were all issues with just my car! Looks like my tuner is getting another video 😂
lol. Yeah 😎😎
Thanks for that Duncan
Just need someone up here do that to my ecu
@@neilbrown5657 possibly could do for you if send your ecu down...
@@racedynamix providing you can access it as my paperwork states ecutek software and it's not locked to andyf id
I think we have a plan then. I will be able to power it up in mine to amend the map 👍
I'm curious now.I pulled up my rom.I have that same dip.Should I adjust it in mine?
I will for you Joe in the next iteration 👍

Both target same 14.7 Afr. The warm up strategy is different 👍

Nice, thanks. Will be in touch for a bit of tweaking soon!
If only I could do this to my my99...
yeah even with remapping on Ecutek, the warm up enrichment tables aren't shown so it is impossible. Only solution is aftermarket ecu I am afraid 👍
Great video cheers
thanks Kalen 😁👍
Greetings from the US of A 🧘🏽♂️
hi buddy 😎
I can confirm my GRB JDM suffers this funnily enough. I give it a min to warm up or it’s jerky with a paddle clutch it’s a joke sir
Will sort it out for you Nathan next time 👍

my mitsubishi mirage does this
interesting..not just a subaru thing then
My jdm does this too. Why do Japan tables have these dips?
yeah it's weird... I can only put it down to laziness for the oe map creators.
