Tuning 02 Suburban 5.3 advice

[joecar]

Might want to set B3609, B3610 to zero, and set B3616 lower to allow easier PE enable.

Erik,

Which methods did you use on your VE and MAF...?

Tuning is lots of fun, nice work on VE and MAF as Shawn said.

Joe, Ive set everything up based on 14.68 in B3601 so Im going to leave it alone for now I think.

Adjusted B3609 to 0 and B3610 to 3000, this Burb never really gets revved higher than 2500rpms unless Im driving it. I have logs where my gf didnt go over 2400rpms ha. Set B3616 to 75%, should I go lower on it?

Added between 1-5* of spark to the high octane table and copied it over to the low (tuning only, when I know how much I can actually run I will take that new spark table and subtract a few degrees for bad gas).

Used Shawn's Calc.VE tuning method for the VE and MAF tables, its pretty darn dead on now for the normal driving cells.

OK well I ran out of time to really play with the spark settings, so I went through the tune and set B0129 back to stock. Added a few degrees of timing all around, should be pretty conservative overall. Reworked the low octane table off the high octane values by subtracting anywhere from 2-5* in the different areas. Cant believe stock commands like -25* of timing in the low octane table, WTF!

Here's the last tune, really its based off the 0006 tune and shares nothing with the 0007 one.
