peyton Posted September 11, 2013 Share Posted September 11, 2013 (edited) Hello all. here is/are my problem(s)1st and most pressing issue is I got the car to run, but the issue is it runs with the VACUUM line from the intake DISCONNECTED.....literally I just grabbed a similiar build and used the VE and the Spark advance and the AFR tables when I did that It almost started right up. played with the electrical trigger and the physical timming and she ran. then I noticed the vacuum was unattached so I attached it and it died instantlySO it wont start with the Vacuum line to the map sensor, when its attached while I'm looking at the maps (VE and SPARK advance) the kpa drops to roughly 30 or so for the VE table I can upload an MSQ for further information but I really need to know how to upload and retrieve datalogs so I can provide more information as to what is happening Build InformationMS2 V3 (built by a noob) -stock map sensor -NO MODS -STOCK B&G CODE -NOT THE EXTRA CODE ENGINE L28et stock 100% stock injectors stock throttle body stock dizzy stock everything Second Issue is I got a LC1 wideband on Craigslist and it was sorta chopped up but I managed to wire it up... the Tunerstudio is saying something like 14V~17v and drops to about 11~12V when starting.... if anyone had an idea how to fix this it would be great because then I would be able to log my AFR for tuning and diagnosis any and all help would be much appreciated.

Matt Cramer Posted September 11, 2013 Share Posted September 11, 2013 Sounds like your tune is too lean, as unplugging the MAP line will make it go richer. Quote Link to comment Share on other sites More sharing options...
dexter72 Posted September 11, 2013 Share Posted September 11, 2013 You should not install the wideband sensor until you get the engine to idle well. An overly rich condition can ruin the sensor. So get the engine to idle well first. Check out your required fuel setting, is it close to a couple of maps that match your set up??. If not you can increase or decrease that setting while the engine is running. See how it runs when you change the setting. Quote Link to comment Share on other sites More sharing options...
mattb3562 Posted September 12, 2013 Share Posted September 12, 2013 Make sure your he and spark tables are set down to the IPA that your idling at...if you're not telling it to fuel or giving a timing command at that manifold pressure, it simply won't react.

niner11 Posted September 13, 2013 Share Posted September 13, 2013 (edited) Post your MSQ file and we can check all of your settings. Also, If you trail a "live" file with Mega log viewer you might see something obvious. Edited September 13, 2013 by niner11 Quote Link to comment Share on other sites More sharing options...
