Diesel Shift Light

[bakerboy]

When in the heat of battle,with a helmet,intercom,looking where youre going doing 80 plus KPH it is just one less thing to worry about

jesus, how do you cope on the freeway at 100kmh

[fester2au]

Man I wish sometimes my diesel revved that hard and quick that I needed a visual indicator to chance gears. I reckon once I get about 500 rpm below peak torque I've got about 30 seconds to recognise that and grab a new gear else risk falling outside my powerband (which is just off idle to about 40000rpm). Phew only just make it sometimes. Mind you this is good seeing as any fast shifting quicker than about 20 seconds seeing a bit of teeth crunching in the agricultural 80 series manual gearbox.

Really if you have the time and can't find anything else and are getting desperate have a troll through the Jaycar catalogue. As already stated they do a few possible items although they are in kit form. One that comes to mind is the Rev Limiter/Gear shift indicator. You need other components to make the rev limiter work so don't worry if you don't need that. "Two lamps will illuminate consecutively before red line....uses hall effect, points, low voltage signal reluctor or ignition coil to measure rpm"

From memory they also sell hall effect kits so anything is possible.

Another is the Frequency Switch - suggested uses: Operate a shift light at set revs.
"It uses a standard tacho, road speed, or many other pulse outputs to switch a relay". Costs about $40 if you buy the kit and the neat little box to stick it in.

Maybe that's 4,000 not 40,000 RPM

Ahhh yes, slight type there. Mind you when I try to rev it near redline I'd swear the noise indicates that it is pushing closer to 40,000 than 4,000.

So what you can't read the other 5-6 or so posts that actually did offer some form of factual help or confirmation. So we pull the piss a little when fronted with a question that could either be serious or total wank factor dribble. When are you guys gunna learn that if you actually do want a serious answer to a serious question that is a bit left field then you need to actually provide some decent information about the situation.

Maybe if presented with somethign like - Can I put a shift light on my diesel. I have a highly modified td42T and already have a X brand aftermarket tacho but when comp racing I fidn it hard to eyeball the tacho and can't hear the engine through my helmet. I'd like to be able to hold peak revs and torque in some critical situations but also avoid falling off my torque band whilst concentating on a tight situation and feel a shift light might help.

could be a little over the top but I'm sure you would get some more direct and helpful answers compared to asking -

Can I put big tyres on my truck.

Go back and read, he has at least 6 answers (without counting) that are offering helpful input somewhere in their post even though we have no idea what the actual set up is currently. Remember the old saying crap in crap out.

Once you've got the shift light sorted you should look at getting some 26inch chromies

[TroopiePete]

Man you guys are a little slow on this thread - only 3 pages!!!

Good to see the shit filter is still switched to full bore..

So I guess the main Question - or answer should be is it possible to swap the Taco you have to one that already has a shift light?
Mind you the one shown on Page two of this rambling would be a tad useless as it would never go more than half way up the dial - little like those stupid Tyre gauges that go up to 160psi when the max most people would use is 60psi, but I guess most people that would install an after market Taco are rice cars running on petrol with a little NOS from time to time.

So I ask again have you considered replacing the Taco?

I guess most people that would install an after market Taco are rice cars running on petrol with a little NOS from time to time.

most people I see with aftermarket tachos have stock engines, with the shift lights set at 2000rpm so it comes on in maccas carpark.

Serious question - do race cars have shift lights? Eg V8 supercars, formula 1, rally etc?

Not an expert in this area - at all... But
I have seen race cars with them and seem to remember this is where the idea came from for rice cars, while you and I don't need them I can see that if you can't hear the motor because of wearing a helmet it would be difficult to know what the motor is up to, also when you are distracted by just trying to keep the car on the road it would be easy to misjudge the gear and motor speed.

Look I gave up long ago asking why someone wants to do something, apart from trying to work out if there may be a better way of doing it for them. when someone is convinced they need to do it why not just help them to resolve the problem.

Couldnt agree more. There are some absolute fuckwits on here, and it is not the person asking the question. If its a silly question they will find out in time. Honestly so many people on here think they know so much in there fucking one eyed view of things.

[bender4865]

Thanks for all the positive replys.

For the others, my question not for an opinion rather than where/how can it be done.

Cheers

You must be new here. Welcome.

[KiwiBacon]

I can see that if you can't hear the motor because of wearing a helmet it would be difficult to know what the motor is up to

I'm pretty sure that wearing grade 5 earmuffs I would still know what a big diesel near the rev limit was doing.
Especially if it's a competition truck with all the sound insulation and interior stripped out.

See if you can find some race car footage from the drivers point of view. Most race cars run a sequential shift light, something like:
:green: :green: :green: :amber: :red: As the revs climb the lights illuminate so they get warning when to shift.
F1 is on the steering wheel from memory.

Wateva man,there's only one person thats replied that even understand where he is coming from and that is Andy.

Mate I am sure you will get heaps of help with that arrogant attitude..
Several people suggested aftermarket shit lights to plug into your existing unit, replacing your existing unit ti a model with programmable shift lot, perhaps as Andy know you by name he knows a bit more about you setup and is able to suggest a more appropriate set-up for your situation.

Shit information in = Shit information out.

We got shit information out regardless of what information was given, yes a few more people did make good suggestions but really is there a need for all the ricer comments and "why do you need that for just go by the noise" real proffessional way to operate.

Probably reckon pyros and temp gauges are a waste as well???

what a load of crap, you got shit info because you gave us none! after 3 pages all we know about your setup is that it is a TD42t that revs to 4650RPM, it has a tacho in it already but no shift light and you really really really want a shift light!

of course temp gauges are usefull (and a pyro is a temp gauge btw...), because they tell you when your engine is running at a dangerous heat level, which without a gauge you will have no way of knowing this for yourself.
and the comment of listening to it and knowing when to shift, is not dumb at all, because YOU DIDNT TELL US ITS A COMP VEHICLE! so we didnt know you would be wearing a helmet... (see a pattern here? no info given, we give crap answers...)


dont be a knob, and you will get decent answers (as well as the usual array of smartarses).

When in the heat of battle,with a helmet,intercom,looking where youre going doing 80 plus KPH it is just one less thing to worry about, and if you think a TD42 will live at 4650 RPM minute in and out with all disregard to RPM you are mistaken. Yes the 300 RPM will help

That may have told you what it was used for but anyway it appears we haven't come up with a solution so we will look elsewhere.

Thanks again

Several people have suggested changing the tacho out to a unit that already has a light, but you have ignored this.

Maybe the light on the tacho would be too small, if so use that light to trigger a larger light on the dash or wherever it is more visible for you.

Shit even a little tacho hooked up parallel to the other and stuffed under the dash to act simply as a trigger will do the job.

Is there a problem with the simplicity of either of these two methods????

If not then there is your answer, if so then please explain the prob' as in communicate with us, or piss off. It doesn't get any simpler than two way communication now does it?

Cheers

[chimpboy]

There are also standalone shift lights, now that we know there's already a working tacho (would have been logical information to post at the top).

[bogged]

Maybe the light on the tacho would be too small,

They are very tiny I'd recommend a new Lightforce Genisis at least. maybe one each side of the cab.

how fecking long did it take you to tell us that tho? thats my point!

if your not dumb and you want answers, you give us all the info from the start. if you are dumb and you want smartarse comments, then keep doin what ya doin and tell us info in dribs and drabs.

you have been given a number of good answers, yet you still claim to have no solution?

what EXACTLY do you want? because it seems that all the sugestions for various ways to rig up a shift light just dont seem to cut it... so, what do you want?

Wake up to yourself No one needed to know anything about why he needed the shift light. The only question that needed to be asked was what type of engine he was running and if he allready had an aftermarket tacho.


The next one of you morons that have replied in this thread with stupid comments that makes another stupid comment here or in any other tech thread is getting a perminant ban from here, No questions asked.

Gentlemen, concentrate:

Tacho:


Taco:


Comprende?!

Man I wish sometimes my diesel revved that hard and quick that I needed a visual indicator to chance gears. I reckon once I get about 500 rpm below peak torque I've got about 30 seconds to recognise that and grab a new gear else risk falling outside my powerband (which is just off idle to about 40000rpm). Phew only just make it sometimes.

A key feature of my car is that i have enough time between gear changes (under full acceleration) to: adjust the volume or radio station on the stereo, take a sip of my coffee, check the time on my phone and tweak the heater temp. It was a factory option apparently.

[pig 83]

I cant remember where i got my shift light from , i think it was auto barn but it was really easy to hook up it was just power and earth and it had an adjustale input on it and you just adjust it to your desired revs i had it on my turbo diesel it worked really well . Hope it helps
