Veero 1 Posted November 19, 2008 The rev counter doesn't show a reading until maybe 2 seconds after the engine has started. Anyone have any ideas why? Once it's running it responds instantly to throttle and engine rev changes. No great problem, just curious really. Share this post Link to post Share on other sites
jackherer 543 Posted November 19, 2008 Odd, I would guess its the needle physically sticking a bit in the at rest position. Is it repeatable? i.e. can you turn the engine off and make it do it again straight away? or does it only happen sometimes? The correct behaviour is for the needle to 'bounce' as the engine turns over on the starter so it should have some movement even before it fires. Share this post Link to post Share on other sites
Veero 1 Posted November 19, 2008 Yes I'm certain it used to bounce on the starter, but now it's fairly repeatable and doesn't look physically stuck. I shall try it a few more times this evening and see. Share this post Link to post Share on other sites
rapidcossie 0 Posted November 19, 2008 Mine does the same, I put it down to mine running thru my KMS ecu and using a diferent pickup? Share this post Link to post Share on other sites
Veero 1 Posted November 20, 2008 No it's 100% repeatable. Tried it again last night and it stalled a couple of times before actually running and then the rev counter didn't move at all until the engine was sitting at idle, a good 3 seconds after turning the key. The rev counter signal is generated via the coil pack right? Could this mean the coil might be on its way if its having trouble starting and generating a signal?

GLPoomobile 958 Posted November 20, 2008 Hmmmm. Sounds possible. Mine has been stalling and not restarting. When it happens I'm getting no feed to either the fuel injection or fuel pump relays. I suspect my coil is the cause since the +VE goes through the coil to switch the relays. My rev counter does not move while turning the engine when the fault happens.

maturin23 10 Posted November 20, 2008 Exactly the same thing happens with my rev counter - short pause after the engine fires, then up pops the needle. Same thing every time. I'm not having any stalling issues, but I still have a really bad case of the 'clicks' and a battery drain. This still happens after putting on a new starter, alternator, soleniod and battery, and cleaning of the earthing points. Share this post Link to post Share on other sites

Stu 18 Posted December 2, 2008 How strange! Mine does the exact same thing! No starting/running problems, just a delay before it registers.. Share this post Link to post Share on other sites
jonnie205 1 Posted December 2, 2008 seen this a few time son gti6 conversions, some do it and some dont, i think it is to do with signal strength or when alternator cuts in Share this post Link to post Share on other sites
GLPoomobile 958 Posted December 3, 2008 I still don't understand the process flow of what actually happens between all the various components between turning the ignition on, then turning the key to the third click, the starter turning, and then the engine running. But I'm guessing that it's entirely possible that the starter could be turning the engine over, and for there to be a few moments delay until the ECU does something, the relays do their bit, and then the coil and amp start dancing together. You surely shouldn't see any tacho activity until the coil is doing it's bit. Does the coil do <something> as soon as it sees that switched live coming from the brown multiplug, or does it need to get a signal from the amp and/or ecu/relays first? I dunno, but it makes my head hurt thinking about it! But if my reasoning above has any logic to it, then I guess the reason why some do it and others don;t must be down to either a difference in how the looms are wired up, or maybe it's just signal strenth as Jonnie says, leading to lazy ECU/relay activity.

Veero 1 Posted December 4, 2008 (edited) Veero - any news on this? It's still starting really badly. Takes ages to get it running right and it's misfiring on idle worse than ever. All this since I bundled all the wiring back under the dash. Either I've disturbed a fragile connection on the loom or the coil has coincidentally died. I have another coild I will try this arvo. Otherwise it's all the wiring back out again. Running bad at idle sounds like ignition components to me though, it's got a brand new cap and arm, but maybe it needs new plugs and leads too.
