Subject: Tips on part-throttle tuning by Dale1990 on 2010/3/22 18:24:06 Hey all, I was hoping I could get a few tips on part-throttle tuning my 90 6-speed. The engine is running fine with no noticeable mechanical issues but during datalogging I can see that my BLMs are not great - fairly rich overall. No major knock events though thank goodness. I already know how to use TunerPro and my Autoprom to change settings and burn chips for simple things like fan temps, injector constants, EGR flags, etc. but I haven't really messed with the VE or spark tables. I'm not planning on using a Wideband until I get my feet wet a little. I've read that starting with getting the VE straightened out first is the way to go - then spark then back to VE. How do you guys get decent data to find the VE changes? Take a long drive then mull over the thousands of data points? Short drives targeting certain regions of the tables? What's the best way you've found to calculate the changes? I've got a nice long trip coming up this week so if a long drive is the way to go then I'm set. If I know what to look for in the data, I'd probably write an app to do most of the figurin' for me. Thanks! |
