Few questions to get me started tuning
Posted: Thu Apr 08, 2021 8:57 pm
Hi, just need a few things clarified before i go out tuning.
My gauge screen is only reading a coolant temp of65-72 degrees, its erratic and i assume this is correct and the sensor is bung, the gauge on the dash is showing normal temp. This will constantly be using whatever multipliers etc as it still thinks its in warm-up mode? FIXED
The History Tables for Wideband state MAP vs RPM, but unlike in the Basic of Tunings instructions, i dont have a Target AFR, so i dont really have an easy way of looking at it and going "oh yes, 2400RPM and 65kpA is equal to 2400rpm/xxVE i need to take out X fuel" What can i do to make that easier to work out?
My O2 volts, running average is all over the shop, between 109-1088. I am running a Spartan 2, are these values right?
So i'll be changing the VE 20-100kpa Volumetric Efficiency etc map for the main fueling, does it always use this or does it target A/F ratio 20-100kpa Air Fuel Ratio vs map and RPM at any stage?
Shitty log attached. could have been better as this was a bit on and off the throttle.
