I've been through the subroutine in the 9653 and 8859 ROMs that determines the weighting factor for the running master load average. After looking at both subroutines, its become clear that setting the over/under value to 255 will fix the low rpm stutter, but it will limit the load-based acceleration enrichment under heavy load conditions, so this may not be the best solution. I have found another way to stop the low load stuttering...

Good info, still spendy 'lil buggers though!

This is an ETS 3586 kit...build thread here: JohnBradley's 2.2 long rod build

It's interesting that you say that as I had noticed some different acceleration enrichment type behavior. I wasn't sure if it was just my mind playing tricks on me though. I'll make the change and report back.

Will definitely share any new info that I acquire. A few questions - The Decel Fuel Cut tables, should i make all of the tables (Decel Fuel Cut Delay #1,#2,#3 ) the same using the values you posted - 32 61 80 95 95 95 95 I also noticed something I have never seen before...when i first start the car it runs rich with negative timing for a while @ idle. Is this normal?, because before (on 96260009) when i first start the car it never ran...

no i think change all tables to the lower value from 9653 table 2... or just change table 3 to the above... i have had decel issues even on 9626 so either of the two work... obviously making all the lower values means even less fuel... but it still pops for me.

I have to assume you don't tune under OSX simply because of a lack of logging tools.. Yeah, it's worked for years. After I did the initial hack to make it build, colby got a first working in short...

The way the SSQV operates when working properly is pressure is fed into the initial chamber, and then through the...
