nerih 0 Posted September 27, 2005 hello, im from the vr6oc forum, and i understand MANY of you have blown vr6's. I have 2 questions. On my odb1 vr6, where can i find a place to splice into so that i can get a good o2 signal? (what colour, where abouts in the loom etc) on my odb1 supercharged vr6, what is the best place to take a feed for my boost gauge, the brake servo vacuum hose doesnt give me boost readings (its before the non return valve, before you ask ;)). Im thinking of cutting into the PCV vacuum feed, and prefer not to use the fuel pressure regulator feed. Is there a free nipple anywhere that i can use? The boost return valve uses a feed of the servo vacuum...it works fine, but i guess it only needs to see vacuum and not boost. my boost gauge currently idles at 20hg, going to 30hg when accelerating hard, i dont understand why it would go down deeper into vacuum, at stealth at 3000rpm it was at 3psi if i remember correctly.

Supercharged 2 Posted September 27, 2005 nerih, Are you the guy that bought the C2 Kit from Ultimatetune?? Welcome to the forum btw! Quote Share this post Link to post Share on other sites
nerih 0 Posted September 27, 2005 yes, i got my kit a few weeks back, was up at stealth last week, got her on the dastek and so on, and the water injection arrives tommorow, to go on. new ecu from the USA is on its way, cat bypass and new head spacer gasket.... people who buy 'kits' need to budget at least 1k extra, its not cheap maintaining a car in this state of tune, damn its worth it. i met one of the members bilingerg60 infront of maplins, he's the second person in 1 day to say it sounds like a jet...and i was only going 5mph LOL (although in first), i really recommend the c2 kit, WITH the v1, its noisey, but damn, its a good noise :). i understand there was a lot of 'discussion' about my ebay antics here, i was patient and a few months later (lol) i got my charger (at a VERY low price)... my visit to stealth was paid for by Ultimatetune too, i can't fault their customer service, its excellent, free fitting too! can someone PLEASE PLEASE PLEASE HELP ME FIND O2 SENSOR WIRE :) Quote Share this post Link to post Share on other sites
Chris VR6nos 0 Posted September 28, 2005 There's a few wires in a row but the one by it's self is the sensor wire you want Chris Quote Share this post Link to post Share on other sites
nerih 0 Posted September 28, 2005 = star. i've got alot of gauge/electrical work to do today. I'm going to TRY* tracing the wire up to the loom where i can tap it easily. do you know what colour it is on the ecu loom? Quote Share this post Link to post Share on other sites
Chris VR6nos 0 Posted September 28, 2005 Forgotten, maybe the blue one with white stripe but easy to find out if you look at the plug by the rear engine mount and pull the sheething back a bit on the loom side and there you go, look for the same wire at the ecu plug, i've measured the lambda voltage at that point to discover if there was a break in the wire somewhere as my probe isn't working but never has from the start, need to get it fixed!

nerih 0 Posted September 28, 2005 does that mean your using open loop mapping? does your car run in the rain as good as in the dry? i find the lamdba is quite good at keeping stoich. near the exhaust mani, i have two plugs, a white one and a black one, any idea which one it is?

nerih 0 Posted September 30, 2005 I managed to get the gauges going, but the O2 sensor check out my water injection thread. http://www.vr6oc.com/e107_plugins/forum ... .php?81037 Quote Share this post Link to post Share on other sites
