Re: TPS Enrichment

without complex piping your only sensing the MAP on one throttle and that fluctuates badly. It's not that bad in rusEFI: 1) We have "MAP Sampling Start Angle" and "MAP Sampling Duration" - very powerful instrument; 2) We have nice and smooth MAP averaging (isMapAveragingEnabled=true by default); 3)...

Re: TPS Enrichment

So with ITBs this getTpsEnrichment will not wok, since between two engine cycles i will never have a tps movement that bit to detect it rusEFI firmware works with ITBs just fine, including speed-density and TPS-TPS enrichment. Have you tried setting "Fraction Period" and "Fraction Divisor" options?

The idea behind KE1xF Kinetis in Deucalion is a combination of several features: 1) 5V-compatible inputs/outputs; 2) High-speed 168 MHz clock - so we have STM32F4-comparable performance guaranteed (most other 5V NXP chips have lesser freq); 3) 3x high-speed hardware analog comparators + 3x ADCs - ve...

HS-mode 168 MHz, which is preferable for realtime multichannel analog signal processing (trigger + knock/ion sense).

Re: Daewoo Cielo/Nexia 1.5 DOHC #51

autotune is trying to catch the correct values. Autotune in TunerStudio often tends to "saturate", when there's a big difference between actual and target values. So I'd recommend to restart it more often. If you see that Autotune has stopped responding and cannot change the VE values anymore, then...

How did you managed it? AlphaN algo ?
Speed density + TPS-based VE table + TPS-based advance table. But it also worked with pure speed density, just not as good as with hybrid MAP+TPS-based setup. As for the MAP, I've enabled option "Use minimal value of = 4" (for 4-cyl).

Re: Idling issues

This does not seem to happen. As rpm's increase above 750 , 1000 or more Rusefi still seem to take values from idle tab...
