Worked like a champ! Fires up as soon as I hit the starter... Went for a ride and let it idle for a bit in the garage when I got back. Engine temp wasn’t as high as a 100° day but still fired up quick when I hit the starter.

I just cheated and mirrored Big Dave from 70-100 KPa / 750-1125 RPM’s. The Top Right of the Tables just needed to be backed off they were way too high.

I looked at few other area’s on that map and I might consider loading it up a running a few auto tunes?

Big Dave,

Was that map canned or from a Dynotune?

That was a Fuel moto map an adjustment with quick tune for the hot starts and a few auto tune runs , Im very happy with the way mine runs

Glad it worked for you

Now do a couple autotunes and you will notice the difference. Assume it is as good as it gets and you will never feel the difference. ;-)

What calibration did the original start out with? Most SE and TTS cals have zero's or negative numbers to start with. Only time one needs positive numbers is low compression. People put to much into the fuel side of starter cals when really. That's the easy stuff that needs to be addressed. As they send out the same old timing tables for most everything.
