Need a little advice from some experienced tuners

Rechecked the stock CAD. Cruising is between 10 and 11. I just added two more degrees. It is sitting around 15 degrees now.

Just got back from WOT test run. The roads are damp so it mostly just spun the wheels through third gear, but with boosting the Torque Based Fuel and adding 10% to the PW, the truck is CONSIDERABLY faster. Interesting note, the EGT really struggled to make it past 1200. My previous tunes were much hotter for the same power.

In cruise, it is VERY quiet and responsive.

Time to do some more reading on Pilot and Post injection.

Cheers!

P.S. Yes, stock wheels.

Good. Glad to hear there are more good results. My testing is going considerably slower as its on my dads truck and he likes to load a tune and drive it for a week to get the feel of it. And really it's hard to get a good mileage average on a shorter time frame

But when I go home it's like a tuning blitz lol. He hands me the keys and says if you break it your fixing it.

That's a trusting father! Good luck with your tuning. It's a fun time for sure!

Haha yeah thanks man. He's seen the research I do before I start anything and I know he isn't kidding when he says your fixing it.

I wrote a spreadsheet to calculate the dwell in degrees. In terms of the stock truck, in the high power, high RPM settings, Chevy has the dwell in the 50 CAD range. Around 16 CAD in the cruising ranges. RPM definitely has effect on dwell time.

StinkyDog,
I'd be interested in that spreadsheet you wrote. Haven't found how to convert us to cad yet. Not much smart

Wait a minute......googled it and found the answer in about 180000000 microseconds

I would be happy to share my spreadsheet, but I can't figure out how to attach it to the post. :(

Update: I figured out how to attach it, however, it won't let me do it with the extension that is on it.

I'll try this and see if it works. It is a link to my public dropbox.

The top file is in Open Office format, but should open in Excel alright. If not, the second one is saved as Excel. However, I am unsure if all the formulas came through the transition.

Disclaimer: If you use this and your truck goes "BOOM!" I am held harmless! LOL!
