Copied over the latest cranking tables as mine were way out of date and finally did the fix for the fans to come on sooner. Too lazy to log but quite a nice difference in IATs when sitting in traffic when it is 80*f+ ambient. Thank you for all your help @Wayno

@Wayno, is your v104 Stage 1 safe to run on pump-gas? You mentioned something that "it is for flex-fuel", but i never will run on any Ethanol.

Haven't posted anything for flex fuel and if i did it wouldn't be for stg1. But yes it's fine.

I see you've changed overrun a fair bit in your latest. Any links explaining what it affects?

Did you look at the table properties?

Throttle plate angle.

This is not the full picture as these are paired with exhaust cam, a 3D graph of the valve overlap would be better. But gives some indication of the work done on AVCS.

EL OTS 91 vs EL v107 Intake cam

STOCK vs OFH vs UEL v107 Intake cam

If I wanted to use the E85 cranking tables with DW 700cc injectors what would I need to scale the tables by? It is current value x old injector scaling / new injector scaling, right? The E85 roms have 171cc/min scaling (stock roms have 228cc/min) and I am assuming I would use 700cc/min as the scaling for the larger injectors. So in that case, the cranking tables should be scaled down to 24.43% of their current values?

I've no idea. Better to start a new thread in software section to ask some of the FI guys that are FI - kodename, ztan, shiv, etc. These values are for stock/NA only.

The E85 ROMs scale "down" the value to provide more fuel for the requirements of E85. So what you need to do is give the new injector scalar the same ratio. So (171/228)*700.

For the cranking values, you would reduce these by (228/700)*original value. That's based on the original E85 cranking tables.

Don't forget to set the latency values too, and confirm that 700cc is the correct value to set.

Your VVT smoothing gives a pretty striking improvement to driveability when just cruising around. Almost completely removed bogging down on light throttle 2500->1900rpm upshifts. Going to give it a go at dialing in a bit more, but fantastic work.

I got 5L/100km @ 115kph / 2200 rpm the other day. That 56.5 mpg. So I would recommend not touching 2200 rpm.

It's possible the 2000 rpm row could use some more advance though as it was also 5L/100km, like this.
0, 0, 8, 10, 12, 14, 16, 19.

I just didn't want to stray too far from every other calibration out there and also I'm tired of flashing and testing.

I've added that timing to the OP as v107.1.

I was using the OFH AVCS tables and it was a bit difficult to drive in the lower RPMs (it felt very gutless below 3000RPM). It kind of felt like I had to avoid having my RPMs fall below 3000rpm or else it'd drop off a cliff and I had to climb back up, but after switching to the v107.1 tables, it felt much smoother and more linear. Thanks Wayno

Attached Stg1 with smoothed AVCS tables at part throttle.
For comparison against vanilla Stg1/v107 only.

It should either feel noticeably improved with better economy
or will feel noticeably rubbish having too much cam advance for stock header.
