Right then, I'm writing on behalf of my mate who has just got a Z TT import. the only problem he has is the tick over is really low and alittle erratic. Nothing bad but how do we increase the rev's?? Is it just a case of disconnectiong the the throttle sensor (if thats the right sensor( the one on the right TB)) and it will reset itself or do you just adjust the idle screws.

 

P.S He's joining the club next week ;)

Was going to set my t/over up-think I'll wait for this thread to go on a bit!........

 

 

Gonna be a long un'!!

Moist.

 

Yeh I`ll have 1 ....:D

Well you just proved you know **** all. What opening angle does the idle valve open to? It can't because its a plunger ffs.

 

Percentage angle !!!! you know READABLE degrees etc. remember at school?

 

Masking running faults???

 

why does getting an engine to run at its best become masking a fault ? lets assume all the circuits and valves, sensors etc. are in order so there are NO faults to mask setting up the base idle as I mentioned earlier will give both good stability and reliability to that stability no dipping of revs or stalling, base idle set at 650 is not correct for every zed in my view and experience which incidentally is over 20 years worth and at least 15 years of that been on fuel injection cars and the last 8 years on zeds

 

Percentage angle? :D WTF are you on about? Its duty cycle ffs. No angles involved. IF all sensors etc were in god order, and STILL 650 won't hold, then the engine is worn out and should be replaced. Lets face it who wants their car bodged? You can keep on digging if you want, hell, I'll even lend you a bigger spade, but the fact is you are WRONG so just admit it!

Whatever happened to the good old days when a pint of redex would solve every problem:D

 

If it didn't it alerted every amateur mechanic in the town to come out to the rescue as the carcenogenic cloud killed the aphids on the roses :dance: :dance:

Again you miss the point! are you actually reading the posts here or just hitting the send key with pre-written misinformed drivel ?

 

The measurement scales. percentage, voltage, what ever are all related to the ConZult and the method used by it for measuring the relevant engine operating components this is industry standard and should be easily recognised by yourself considering the Volume of cars you must work on

 

If 650 is as you say the correct base idle speed Without idle adjust why is the ConZult which is based on Nissan own system set to disable the idle control valve back to base 15% duty? ( your term) which would render its own balance tests inoperative ? The system uses both rev drop and alternator output to read the differences between cylinders once the revs drop to below 500 rpm the accuracy falls to a point where it is invalid???

Dig? yes I will because eventually you WILL get the message, take a moment to contemplate why we are having this discussion, it comes down to opinion not inexperience not bloody

mindedness just opinion its just a shame you cannot accept your opinion is wrong.

 

Jeff TT

It disables the valve to 15% duty to give an increase in the revs for the balance test. 15% and ONLY 15% is used, no feedback to increase the revs if they drop. Feedback is the key to all this. How can the ECU possibly control the idle at 750 if the base idle screw is set to 100rpm above it???

LMFAO are you serious? You just contradicted yourself :D I hope you've got a HUGE hangover in the morning because the shit you've posted tonight would suggest its on the cards.....

Errrrrr I think I have learnt more about Idle control than I ever want to for the rest of my life :D
