Apexi Auto Turbo Timer!

[r33boi112]

Hi,

Is there something wrong with my turbo as when im driving around not hitting boost and have to stop at the lights for a minute or two, the display on the turbo timer will slowly climb from 20sec to about 2.5 mins..

Its a r33 and its basically stock...

Thank you

dont recon

more info?

Doesn't matter if not hitting boost, there will be hot exhaust gases still flowing through it.. the logic of the timer itself is all guestimates, though you might want to get a consult cable or a aftermarket water temp gauge incase the coolant temp is sky rocketing (stock gauges dont hit the red part till something silly like 120c, even at 100c it won't budge from the normal position)

Im pretty sure those Apexi turbo timers take a guesstimate from the o2 feedback. Maybe it thinks while your idling your giving it the beans.

Mines a bit odd too (not apexi) cruising at 100km/h it climbs pretty steadily to about 2mins aswell. I think its rev based though. Derp.

Dont worry about it. Rip it out and throw it in a bin where it belongs. They are NOT needed!

I never use mine as a turbo cooldown thing anyway. Times i use it is when i stop at a corner dairy and grab a V, or after flogging it round the track or the likes. Other than that i just turn it off.

yeah 2 minutes is a bit excessive, as gotrice said it looks at 02 feedback to predict engine load, thus to guess how long it should idle for

the temperature of the turbocharger would remain 100+s deg for 15min+ of the engine being off, so you arent cooling down the turbocharger, just the bearingsany more than 30 seconds probably achieves zero

the turbocharger turbo timer idea comes from cooking the bearings in certain bearing type units

i forget which ones, but some are more prone to failure if they have an excessive core temp and then the oil flow stops

the oil flow is an essential coolant and if it stops running instantly and the core temp is excessive then they can fail, or reduce their life

but this would only occur if you were say doing a full spec rally stage or a series of laps on a track and then instantly turn the engine off and have a certain bearing type. im pretty sure this type of issue was nuked post 1980s with ball bearings etc - they are more resilient now

Thank you guys for the info
