2022 Launch Help

[FarmerMagnum]

Hi All,

Trying to understand/improve my off the line performance and I'm wondering if the 2022's are programmed a little differently than older models. I've got a 22 GT2 AWD with JB4 running E30 on map 3 and K&N Drop-ins - obviously not heavy on the mods yet.

Both when using launch control and just mashing the pedal from a stop the car will roll forward for what feels like a full second then blast off like a rocket. Honestly it feels like the throttle is opening really slowly from a stop. My draggy says the best 60' time I have gotten is 2.27 seconds and the best non-1ft correct 0-60 is 4.58 seconds.(that was DA of 3300). The fastest 0-10 i've got is .75 seconds. Pretty rough. I'm seeing sub 2 second and 4.0ish times all over this forum.

Has anyone else with an AWD 2022 had this experience or is there something I can do to improve things? My JB4 logs look great with very little timing pull and great AFRs. No stuttering or stumbling. Once it's moving the power is definitely there.

IMHO, LC doesn't let you build enough boost, so you get pretty flat performance for almost a second.
Late last year I got a Lozic TCU with LC torque limit disabled, but I haven't been back to the track yet to try it out.

yep, you aren't getting any boost at first, the car is probably trying to protect the transmission by being tuned this way. You either have to do the Break Snip mod or get a TCU tune like Lozic or Lap 3. Every stinger/genesis model using the twin turbo engine has this trait. I wouldn't do anything about it unless you plan on taking the car to the drag strip.

Thanks for the replies.
Yeah, half a second I'm probably not going to miss is not worth a 10k transmission replacement to me right now. I think in the future I'll do some exhaust and intakes and just try to get the turbos to spool a little faster. I purchased the EWG wires with that in mind anyways.

Thanks again!
