Default Help with my C63 JB4 - solved only with removing jb4 - 05-27-2019, 11:21 AM

Going to install this finally on my 2017 C63 W205 sedan EU.
After install use only map 1+2 ? Send logs to Terry or who? After reviewing the logs he can make some setting? I have been using Ecutek before.. i have 98octane fuel and possibly E85 also.

I would like to make some video comparation before/after and I am also going to dyno same day.
Thanks

Log looks clean to me on map1. No obvious sign of issues with boost, timing, or fueling.

Thanks Terry. Lowering boost in those gears means using map6 with individual settings? Or where can I set this in Android App?

So after few hundreds kilometres with JB4 I have to say that the increase of power in my C63 is very addictive. I am glad that I went this way.

With map1 or mostly map2, (I have new P4S 275 in the rear), there is still something weird even with higher gear, like 4 if I do full throttle there is some slowering of rpm, its like when you have too much boost and clutch cant take it (had this with previous car). Is it really some DSC thing (no TC light) or ?

Friend of mine who was doing the install with me, thinks that he can see it here, but it sometimes happens in lower rpms, around 4krpm. Will try tomorrow to reproduce it and send the log

View logs in the JB4 windows interface.

I don't see any issue in these, at what time stamp do you think there is an issue so I can zoom in?

I tried to make a video with map2 and jb4 C63 jb4 on Vimeo and if you compare this video with this one with map 0 you can clearly see rpm problem c63 jb4 map0 on Vimeo

so what do you suggest Terry?

That just looks like some sort of slippage and catching again, of tires or trans, rather than a tuning issue.

If map1 has the issue then use map6 to lower boost further as needed in that area.

I dont think that its slippage of tires, thats why I did the video on dry Road with heated P4S, on 5th gear in 80mph (130kmh) with ESP in sport mode..

Car is 2017 model, with 30k miles so transmission should be ok

What settings do you recommend for map 6?

update : with map 6 seems like no issue. Will play with it. where to add more boost?

Well I tried several settings for map6, car is behaving OK. Could you tell me which PSI uses map1 compared to map6 ? There is less taper in higher rpms?

Here are some logs with this settings. Could you please check them?

Here is screenshot with my settings od map6 and also screenshot of max 23.1PSI which scared me .

Thanks Terry. I have to say that its too much fun with map 2, but the ''slipping issue'' is worrying me.. I was thinking if it could be some transmission torque limit which cuts fuel or releases friction in transmission, because in is not happening on 2,3rd gear only 4+5..

What do you think?

It's difficult to tell, we haven't observed anything like that in in our development car nor had anything else reported. I'd just stay conservative on boost for now and we'll see if we can triangulate in to your issue in the future.

Sounds like a misfire code, from plug gap being too wide for the boost level. But none of those seem to be ECU codes. Maybe delete all codes so when it comes back we have a clean slate to look at.

On plugs we've only used OEM so far, but I'd close the gap down to 0.022".
