mattnorgrove 0 Posted June 3, 2008 Right then, hopefully a quick one this. The coolant temp on my VR when on the motorway drops to about 70c My question is this, will the engine revert to cold mapping (i.e use more fuel)?? What temp does the cold map cease to be in effect? Cheers chaps... :) Quote Share this post Link to post Share on other sites

Walesy 0 Posted June 3, 2008 Sounds like your stat might be stuck open if it drops that low on the motorway? Quote Share this post Link to post Share on other sites
Kevin Bacon 5 Posted June 3, 2008 70 on the gauge is about 80 degs C, which is when the stat opens. Lambda closed loop engages when water temp reachs 70 deg. That's why VRs always feel quicker when they're warming up because they're in open loop and running rich :D Does it take ages to warm up? Quote Share this post Link to post Share on other sites
mattnorgrove 0 Posted June 3, 2008 Search is your friend viewtopic.php?f=1&t=68720 8) Cheers Dink, I've read that thread, and very good it is too. What I need to know though is will the ECU go back to cold map if the temp drops below 70 after it has reached temp initially. Couldnt find that in there... Kev seems to get up to temp quick enough, 5-10 mins tops... Quote Share this post Link to post Share on other sites

Yeah I think it is, gonna have to get it sorted I reckon, but its gonna involve doing the housing too, as thats never been changed... :( Quote Share this post Link to post Share on other sites
