traction problem

[m4f82kuwait]

after installing downpipes and switching to map 2 I'm having a traction problem at 3rd and 2nd gear. I've noticed it when i was roll racing 50 or 70 at the begining it went hard then traction sign shows up and my rpm stays still at 4500 rpm and sometimes again at 6000 once i hit 4th gear it runs normally.

so the problem is that i need to change my tires? or too much boost or some m4 safety stuff.

when i was using map 1 i had no problem with 3rd gear i just loose traction and my rpm goes on without stoping for a less than a sec.

sorry for my bad english

Turn off traction controll

i always turn it off traction and MDM

[m4f82kuwait]

thanks for help mdm was the issue. DSC off alone solved it.

I don't think that is very sound advice.

Loosing traction is one thing at lower speeds, but in upper 3rd gear/4th gear, you do NOT want wheel spin going close to triple digit speeds. It can snap loose on you and be unrecoverable.

Get stickier tires I used to have that issue I got wider and sticker tires R888 or cups help, and all that sand doesn't help with traction either :P

Tires, alignment and suspension are key to great traction. Pirelli Trofeo R are excellent. We run them on our 1000hp 997 Porsche turbos on the street and they do really well. They won't last long though but those are the tradeoffs.

This is absolutely on point. If you have ever had the car unexpectedly break loose at higher speeds, then you know... If you have not had this happen, then be careful and leave MDM on. Just like TRZ06 said - it can snap loose - and it happens quickly and violently and it is difficult to recover from. I had this happen in my M5 some years back and I will never forget it. It makes me really hesitant to be full throttle with TC off during gear changes.

This really interests me, as I plan on getting Ohlin R/T coilovers pretty soon and will be doing a "street performance" alignment as well soon.

It would be amazing if those two changes increased rear traction and front-end bite

Do you have a JB4?

If so you can limit max boost on lower gears

yes i do but I'm new to jb4 so i just need to search for a while how to lower the boost.

OBDII In Dash Menu

+1 Good advice..

and get stickier tires and wider helps. I put 285 RE-71Rs on and love the extra grip.
