Tuning Anomalies using TuneECU and wideband

[Claviger]

Which tune did you use of mine, Hybrid, Domination, or Smooth? Glad it worked out for you! Nice to have confirmation from another captain that it's not just my optimistic butt dyno that registers some extra torque lol. Just curious.

The secondary map signals on 2 and 3 might be used for the per cylinder vaccum reading for balancing them, not sure though.

As an aside - I would strongly warn against advancing the timing anywhere in my tunes without a proper load cell dyno, pyrometer, and exhaust gas analyzer. The values as they are, are safe and I used some professional ignition tables developed using a load cell dyno as a guide, then pulled a little from their tables for safety and smoothed them.

I just don't want to read a story about someone reading advancing timing can increase power and blowing a motor because they added way too much timing not realizing my tunes already use an improved timing table.

I have had a report of a virus being embedded in my tunes. Due to this I will be removing and reposting Domination Tune later today. If you have concerns please convoy me and I'll post it to the convo.

I can assure you it is nothing I have intentionally put in the file, and my PC is very well maintained and protected.

@ROCKETHEAD: Did this solve the high idle issue?
@Claviger: Nicely done! Confirmation of what I had found. Also, points out that a lot of dyno tunes in use make great full throttle power but are no better or worse than stock at cruise and mid-throttle.

The bit about WOT being tuned but nothing else refined is why I set about doing this. That combined with lots of tunes having apparently random fuel/ignition spikes in them tells me they were a quick job done with minimal revisions. Precious few 4 stroke engines have any reason to add 20-30 percent fuel 400 rpm apart, they don't just magical flow that much more 400 rpm later (specialized race, turbo, and variable valve time engines excluded).
