OFT Stage 1 Cold Start Stall

Hey Everyone,

I recently flashed to OFT Stage 1 V4.0. This morning the car stalled a few seconds after starting. The temp was about 10-20F. The stall happened when in was in neutral and let off the clutch, I assume the added load of the clutch disc, input shaft etc was a bit too much load for the engine a few seconds after startup.

I noticed that the rpms immediately after startup are much lower than the OEM tune. Can I just adjust the cold startup rpms in RomRaider?

petrol or e85?
i don t think the clutch disc is too heavy for. the engine, the moment you leave the clutch the ecu "uses" a table that essentually pulls ignition timing, that causes the rpm at idle to dance around

maf scaling is for a stock airbox, do you have something different?

in romraider you can open the 2 maf compensation after start tables and raise the value on the 2 first rows
they force the throttle to open a bit more

I'm not saying the clutch is too heavy for the engine. I think the idle speed is just too low for very cold weather.



I'm on the stock air box.


Would it be easiest to edit the Idle Speed Target (A-F) tables?
