supra-ireland Posted October 19, 2009 Share Posted October 19, 2009 (edited) My turbo timer seems be running on a little longer than usual. After a short, 5 mile drive without using hardly any boost it runs on for about 50 seconds. I can't be 100% sure how long it used to run on for on similar trips but I think it used to only run on for about 10-20 seconds. After driving pretty hard the timer goes up to about 4 minutes but quickly drops to under 3 minutes once I ease off. Would times of 4 minutes for hard driving and 50 seconds for short trips sound a bit much or is this normal? I'm worried that the oil in the turbo is heating up more than normal. -Cheers... P.S. It's a HKS Turbo Timer. One of these. Edited October 19, 2009 by supra-ireland (see edit history) Quote Link to comment Share on other sites More sharing options...
supra-ireland Posted October 19, 2009 Author Share Posted October 19, 2009 Sorry, I've been assuming that the length that the timer runs on is based on the oil temperature inside the turbos. Is this incorrect? Can someone tell me for certain what determines the length that these HKS timers run on for? -Cheers... Quote Link to comment Share on other sites More sharing options...
Gaz6002 Posted October 19, 2009 Share Posted October 19, 2009 I'd advise ditching it and cooling the car down properly mate. It's not a good idea to leave a car idling, and is illegal if you leave the car before turning it off. Run the car gently for a few minutes if you've been thrashing the car. That's a lot safer.

supra-ireland Posted October 19, 2009 Author Share Posted October 19, 2009 God no, I don't want to get rid of it. I'd keep forgetting to let the engine run on when I stopped. I just want an understanding of what controls the auto mode, i.e. what determines how long it runs on for. Quote Link to comment Share on other sites More sharing options...
Branners Posted October 19, 2009 Share Posted October 19, 2009 My understanding is that it measures how much current the alternator generated which is in proportion to how hard the engine runs. You then set your preference on how long it should run depending on how much power it saw the car generate and thats how it runs longer the harder you drive the car. It wont be measuring engine temp or oil temp at all. I have one in my car but only because the previous owner had it. I wont take it out but I also wont leave the car idling on the turbo timer and walk away as I dont trust it to leave the doors locked.

SupraHuman Posted October 19, 2009 Share Posted October 19, 2009 It's on a timer,set to whatever interval you choose. Quote Link to comment Share on other sites More sharing options...
supra-ireland Posted October 19, 2009 Author Share Posted October 19, 2009 It's on a timer,set to whatever interval you choose. Yes but there's an auto mode as well that works out it's own delay. Cheers Branners, that's interesting that it works off the alternator output. I wouldn't walk away from it either until it has stopped. Thought it might actually have been your old Turbo Timer. OGC ring any bells or am I mistaken? Quote Link to comment Share on other sites More sharing options...
dr_jekyll Posted October 19, 2009 Share Posted October 19, 2009 leving the car to idle is not good , your better off just driving the car gently for a few mins to cool it then turning it off wen you stop Quote Link to comment Share on other sites More sharing options...
RobSheffield Posted October 19, 2009 Share Posted October 19, 2009 Do you live on an estate or by a main road? Do you arrive on your drive at 100% throttle and full boost? Quote Link to comment Share on other sites More sharing options...
supra-ireland Posted October 19, 2009 Author Share Posted October 19, 2009 Do you live on an estate or by a main road? Do you arrive on your drive at 100% throttle and full boost? No, the 50seconds of run down time occurred after driving easy with zero boost. Quote Link to comment Share on other sites More sharing options...
Gaz6002 Posted October 19, 2009 Share Posted October 19, 2009 No, the 50seconds of run down time occurred after driving easy with zero boost. It shouldn't need cooling down then Quote Link to comment Share on other sites More sharing options...
supra-ireland Posted October 19, 2009 Author Share Posted October 19, 2009 It shouldn't need cooling down then That's what I thought. I think the timer has only started running on so long recently. Don't know why though. Quote Link to comment Share on other sites More sharing options...

supra-ireland Posted October 19, 2009 Author Share Posted October 19, 2009 Easy solution drive steady for the last 3 miles home turn the key job done Well I was kina hoping to discover what was making it stay on. I guess it could be a fault with the timer or with the alternator. Has anyone else had a similar thing with these HKS timers? Quote Link to comment Share on other sites More sharing options...
dr_jekyll Posted October 20, 2009 Share Posted October 20, 2009 just ditch the timer mate , stick it on ebay and let someother mis-informed person give you some money for something you dont need. Quote Link to comment Share on other sites More sharing options...
pistonbroke Posted October 20, 2009 Share Posted October 20, 2009 Have you changed your battery recently, or diconnected it for any reason? My old one did this when the battery was disconnected. When it came back on, it wasn't in auto mode, but was on some sort of default time delay. Quote Link to comment Share on other sites More sharing options...

My old one did this when the battery was disconnected. When it came back on, it wasn't in auto mode, but was on some sort of default time delay. Now we might be getting somewhere. I hadn't driven it in a while and had to jump the battery right enough. It's definitely in Auto mode (Ta). I've tried cycling through the various modes and there is only one automatic mode. It's not running down for a fixed period, it's starting off at 0 and building up to whatever value. I've tried resetting S+T2 but to no avail.
