    This transmission uses the same gears as the stock transmission. Not sure why that would need to be changed unless the slipping converter is coming into play.

  4. Built NAG-1/A580 harsh shifting at low loads

    Hi guys,

    I've done my fair share of stock 5 and 8 speeds but this is my first built A580. It's an Extreme Automatics transmission with a 3000rpm stall.

    I've flashed this thing probably 20+...
  5. Knock Retard on modified engines- What's the answer?

    I'm sure many of you have seen it. Knock retard on modified Gen V engines. Whether it's a pulley on a LT4, or a supercharger on a LT1 or even just headers. There are countless unanswered threads on...

    I did find that running richer helps, no doubt about that, but there's no good explanation for it. The wideband was mounted in the rear o2 spot on the dyno. Through quite a bit of testing I've found...

    So we tried the Procharger 2 bar with stock SRT4 2 bar scaling which reads 98kpa a KOEO and pretty much traces the boost curve from before. Exact same stumble at 2,400-2,500 rpm. What odd is all...

    I assumed this was the issue from the previous tune which is why we switched to IDs. Used their data as well. Thanks for the input, though.

    I've found even on the stock ATS-V tune it will shut the throttle to control torque. This has been up for discussion for a while. Any input on throttle closures aside from the peak torque tables? I'd...

    Just do some basic cam sweeps on a dyno. Change cam timing in small amounts and record the changes. You will have a sweet spot for making TQ at different RPMS. If you don't have access to a dyno you...

    Having the same throttle closures another member was talking about. Any input on this? seems to happen pretty relentlessly.

    Thanks Higgs!
    I will try all of this from a troubleshooting standpoint, but I like the idea of a stock high/low oct table (for 87 fill ups) and maximum power on E85 by modifying the flex spark only....

    Hi guys.

    2016 Sierra, non-flex fuel model with sensor added. Ethanol is confirmed at 70% according to ECU.

    The truck responds to all changes I've made in the ECU so far, but seems to run...

    I've noticed this as well. Cranking and idle spark at 13-15* seem to help a tad, but i'm still curious to what people find.
