Mach V Dan Posted February 22, 2005 Author Share Posted February 22, 2005 ops my bad, what i meant to say is it's alittle low off the bottom and is great at 5000 .i really need to proof read my posts first. I'm a little confused about your posts. Were you looking at the second graph in the thread, which is of a stock car? --Dan Mach V FastWRX.com Link to comment Share on other sites More sharing options...
Mach V Dan Posted February 22, 2005 Author Share Posted February 22, 2005 Dan, do you have the AFR ratio chart that goes with that dyno chart run? I didn't output that, but it's around 11.0:1 most of the way out. It dives rich at first, as it transitions from the stock fueling as the boost comes on. --Dan Mach V FastWRX.com Link to comment Share on other sites More sharing options...
Xenonk Posted February 22, 2005 Share Posted February 22, 2005 Sounds good Dan! I can live with 12:1 and 13:1. Keefe Keefe Link to comment Share on other sites More sharing options...
dynoguy Posted February 22, 2005 Share Posted February 22, 2005 dan what i see in the 1st posted graph is the power seems the same untill 3000+ rpms between stock and the tune. my stage 1 AP tune about 15 better from 2000 than stock. mike Link to comment Share on other sites More sharing options...

(I try to roll onto the throttle gently, so as not to make the car buck on the dyno. But not being a robot, I can't reproduce the same roll-on with each run.) But I'm glad you are happy with your car, Mike. --Dan Mach V FastWRX.com Link to comment Share on other sites More sharing options...
Mach V Dan Posted February 22, 2005 Author Share Posted February 22, 2005 Sounds good Dan! I can live with 12:1 and 13:1. Erk! 13:1 air/fuel will almost certainly result in detonation at wide-open throttle and full boost. --Dan Mach V FastWRX.com Link to comment Share on other sites More sharing options...
dynoguy Posted February 22, 2005 Share Posted February 22, 2005 i seen the same thing when we dyno'd my car but being an auto it was easier to dump the throttle the only thing that happens it depending if i was hi or lower in speed when the boost came on seemed to make a difference in my lower rpm #'s Link to comment Share on other sites More sharing options...
