    I added a full 6 degrees of spark advance in the idle region, from 22 to 28, and I seem to have plenty of torque. I have good AFR control at all temps because I have tuned the MAF and VE tables in...

    Since we are on the topic, last two nights I went out to start it, I had it tuned perfectly the day before and the next day it says it isn't getting enough air. It warms up and the step counts go 100...

    Thank you Greg. I ended up having to enlarge the IAC bypass port with a dremel. This helped my issue significantly. It should still be bigger but I don't want to tune the IAC steps vs. effective area...

    Just my two cents, I have been working on and learning my idle for quite some time now and I spent hours and hours dialing in air flow and IAC tables to get it to idle right, go into gear right, and...

    You CAN log AFR with stock o2 but its only accurate within a very tiny range. Like 14.5 to 14.9 AFR or something like that. Not a big enough range to be of any use unless your tune is really close...

    When I run in open loop, disabling the VE, my wideband says the MAF is spot on. Unless I didn't correctly derive my transfer function for the WB when I brought it into HPT. I also have not even begun...

    My scan says my desired air flow is .3 lb/min while the dynamic air flow is about 1.76. The IAC is at zero. The car will not start when it is cold and it wants to die when coming to a stop. There is...
