Your only low on the first pull between 3200-4000 rpm where there is weirdness going on with your requested vs actual. On the last two pulls which both start at about 5000 rpm boost is not low, the taper is as advertised, Not sure if that first pull weirdness has something to do with auto trans or xi affects on load but you should run some more WOT logs in that rpm range to see if it was a fluke or something is really going on.

that pull was just flooring it in 1st, no brake boost so probably thats why boost is lower in 1st but i thought the targets were higher for stg1 even up top?

http://www.datazap.me/u/stanlalee/st...d-afr-and-wgdc See how much easier/cleaner with a single gear pull from 2000-redline. To convert those boost figures to psi at any given point use (boost figure shown-1022)x.0145. ex 2000 on the graph = (2000-1022) x .0145 or 978 x .0145 = 14.18psi. 1022 is my ambient pressure here according to the car (sea level is 1014 or something like that). and here is an unmodified stage 1 OTS log http://www.datazap.me/u/stanlalee/vi...-3rd-gear-pull Last edited by stanlalee; 02-15-2014 at 02:49 PM.. |

I'm running Stage 0 as of today. Holding off on Stage 1 until I get my charge pipe on and can throw some octane booster in with the 91 we have out here.
