This is a very good thread! To me it seems like "lean tuning" can only be done in Open Loop... I added a few degrees of timing, originally commanded 16.5 AFR & added a few degrees of timing; -...

I'm experimenting with MPG here & have read many other posts; My Question is: when my tune is commanding Open Loop, (IE, closed loop is enabled at 284 F)

Why do I have a LTFT that varies ???? ...

On this tune, I had this car at the drag strip and saw a max of 1.5 KR; it's a daily driver & I recently did a MAF tune on it; I'm really surprised to see some KR in the Low RPM band.

I scanned...

This is like learning how to ride a bike; Thanks for being a mentor Russ! :) Before tuning, my LTFT would lock at -2.3 at WOT; now they lock at 0.0 (regular driving seems to have much better LTFT...

So, with the newer open loop table that we have, there is no need to tune the lower half of the MAF frequency & the upper half separately? I'm assuming that with the OL table commanding 14.7, that...

I was initially confused by this... To clarify, I think I should leave the PE at 14.7 for doing the first part of the tune, under 4,000 RPM & under 50% TPS for the lower MAF cells; then when I...

I have an LC1 permanently installed, so I'm assuming I can go to the "Open & Closed Loop" tab & set the coolant temp to 284F (so that closed loop doesn't enable)

Isaak, this might be a bit late, but it looks like you need to add the MAF freq error to the primary table in the VCM scanner.

Thanks for the reply. I will temporarily remove my wideband and put the stock O2 back in the rear.
