So who wants their ECU's "Chromed"?

[sublime_whatigo]

Agreed. I'll start with a question.

What is everyone with a 1G doing for timing? Just pulling 3-4 degrees on the top end and scaling it back to no change or 1 degree pulled on the low? Also just want to verify that evoscan will be giving the reading for the new CAS setup? Is that something that could be corrected in future versions?

Aaron came up with an equation to compensate for the sensor lag. I had an idea for a tuning tool to implement it.

What you see in EVOscan is what you got.

I thought EVO Scan showed what the ECU is calling for, because the number for timing I get from EvoScan matches almost 100% of the time to the timing map for a given load and RPM.

The equation to calculate timing is fairly simple. You take RPM*.0005 and subtract that from the timing map if you are running the old style cam/crank sensor.

beautiful shiny mirror like chromed ECUs only here.

Aaron, everything is off. Not just ignition timing. I'll explain later.

Greg, you going to be at NG?

test it with a timing light under load and I bet you'll see something scary.

Explain. Because I bet I wont.

I know EvoScan shows what the ECU is actually calling for. I know that my car having a 1g setup will add progressively more timing as RPMs go up. I compensated for this by removing incremental timing at various RPMs to account for this. I.E. at 7000rpm, I wanted to run 20 degrees of timing, so I set the ECU at 16, because RPM*.0005 = 3.5 (rounded up for safety), so 20-4=16.

Yes.

I'll be at UMG too.

Ask Jesse how his last engine pounded out it's bearings. My memory is foggy right now. Something about timing advancing itself 3-4 degrees under load beyond the set correction that works under no load revving that everyone does for the conversion. I could vary well be misremembering.
