Stupid Noob Spark Table question for MSPNP MegaSquirt
Okay, I'm getting snowblind trying to wade through everything you need to know to tune. All I really want to do is pull some timing a la the Bipes ECU to compensate for about 5 psi on my Greddy setup.
I understand the timing numbers and obviously the RPM, but the kPa I still don't 100% fathom. I know the definition, but what does 100 kPa correlate to? 19 kPa, 230 kPa? I think that the larger the number, the greater the air pressure but where's the median? I'm guessing I don't want to pull timing from everything, but only when the airflow/load increases. That's where I'm a bit out to sea. Any and all help would be appreciated. Cheers and TIA, Jon |
100 kpa (approx)= air pressure at sea level, 0 psi boost.
6.9 kpa = 1 psi. 106.9 kpa = 1 psi "boost". 114 kpa = 2psi, so on and so forth. |
Aha! Simple. Direct. Thanks.
Cheers, Jon |
