Hi all,

So i have been trying to tune 3D sd on 2150s [ pump gas ] idle and cruise.

I am constantly getting STFT Max +25-22 at idle and cruise. I have de-linearized map volts to kpa & kpa to load values in cruising areas.

So the question is.. Is there any relationship between map volts to kpa fueling and STFT ? or it is purely Scaling and Latency related.

Send me your SD 2.0 Rom, maybe would have not the best injector latencies

Hi, what is your opinion on my question ?


Can you please share your rom latencies and SD map volts to kpa settings ?

MAP volts to KPA does affect load, however you shouldn't have to touch that table unless you really have to. If you are trying to adjust your fuel trims stick to tweaking the injector scaling and latency tables.
