[OFT Question] Car Bunny Hops After Changing CAM Tables

[Muchikori]

So as title suggests, i changed the Intake and Exhaust CAM Tables on the Stg1 OTS at [.8 Load and up, 3700 and up] and noticed that after flashing it to the car, when i reach a certain RPM the car starts Bunny Hopping then stalls.

I know i reported this on a separate thread but that's for a different table. This time, i changed the base map without changing others.

Will add pics later if needed.

Did you touch engine load limits?

Logs would certainly be helpful.

This sounds strange for just changing intake cam tables ie engine stalls.

Are you sure definitions are correct ? And you flashing correct tune, just seems weird like your ol/cl delay changes causeing stall. Did youback out all the other changes. Maybe start with fresh copy of tune

here's a copy of what im using (ots as base, rev7 as the one with only cam changes, and definitions) i downloaded the definitions from oft for my ECU's version(ZA1JN10C) and made the changes there... would it be possible that rom raider v0.5.9 is the one screwing up the file?

I'll try again using a fresh copy

Hi Guys,

I went and created my changes from scratch (OTS + Definitions newly downloaded) and unfortunately it's still happening

I made sure i made logs this time: https://datazap.me/u/muchikori/bunny...10-11-12-13-14

Does the unmodified stage1 v4 Bunnyhops too or does it drive. Good

Are you sur3 you only have those defs on romraider?
Also dont understand why are you trying to do those strange things on closed/open switch an those unusual cam settings?

Yeah only one definition is on my Rom Raider.

I just wanna make the car faster as these are some of the similar changes i did to my Mazda when i was tuning it. sorry iknow those are 2 differnet platforms.

Would you be able to give me advise as to which tables should i modify in order to squeeze out some power from a drop in filter + inlet tube?

[tomm.brz]

Stage 1 are already wrtten to squeeze out more power from stock car stck exhaust header, i wouldnt modify the cam
I would just modify last value on the 2 engine load limits tables as i see my17+ tends to go higher than 1.3 and just try the map for some time

See if it knocks and how is the afr and ltft

I wouldn't bother bar a bit of MAF scaling and as above. You're not going to gain more than a couple of HP max, nothing you'd notice.
