Tachometer Installation

Discussion in 'Suzuki Carry' started by Tom Notch, Feb 21, 2008.

    I purchased a SunPro tachometer for my 2000 Suzuki Carry. The truck has coil over plug ignition and has no distributer. The Tach was designed to work with a Distributer-less Ingition System (DIS) and has dip switches to allow it to work on any engine from 2 to 12 cylinders, so it should have been an easy installation. Problem: Where do you get the trigger signal for the tachometer? I could not find a lead wire behind the dash or on the engine. Has anyone installed a tachometer on a newer generation Suzuki mini who can give me a pointer? Thanks.

    I"m in the same boat as you Tom, but I have a 93" Carry and just purchased a simaliar Tach Mine looks to hook up to the Dist. I was wondering the very same thing about tach's on these trucks. the engine is so quiet it hard to tell what its doing. Good luck with yours. The only problem I've seen eith mine was the wire length that came with the gauge. bout 16" not to thought ful on there part.

    I have a 1993 Mitsubishi U14T and I just installed a iEquus model 8068 tach today and it works on engines from 1 to 10 cyl also it comes with a inductive pickup that you just clamp around any plug wire for your tach signal hope this helps

    WHERE did you install the guage it self? dash board? The one i got is a "Glow Shift"
    its not a bad guage looks easy to install but it didn't come with much just playing with where to put the guage might not have to much choice
    thanks

    Hey Tom Notch,

    Find the Hall Effect sensor and check to see if you can pick up a signal from there. On my '99 it is located on the rear of the cylinder head possibly being driven off the cam shaft. Another name could be cam position sensor, but the device is an optical or magnetic switch that controls the spark. Also called SPOUT, "spark out" signal. Mine has three wires one will show the firing signals.

    As a test you might push a straight pin through the wires one at a time and with a test light touch the straight pin and see if you get a flashing light or solid light or no light. Obviously the one that flashes is the signal pick up.

    Hope this helps.

    Thanks to all of you for the prompt quality information. The cam position sensor sounds like the ticket. You guys are amazing!! Tom

    I just received my Equus 6068 tach and noticed in the installation instructions the following:

    C. For conventional 4-cycle and Coil on Plug ignition systems, connect the
    GREEN wire to the negative side of the ignition coil (on Coil-On-Plug
    Systems, make the connection to the negative side of one of the coils only).

    Does this help you? What is the best way to find the negative side of the coil-on-plug?

    Check the brown and white coil wire. The electrical diagram shows it as the negative coil wire

    Yeah, I was kinda thinking it is probably in the 7500 to 8000 RPM range for redline.
     
  15. carry92

    I think that you would get valve float before 8000 RPM.

    The F6A engine has peak torque at 4000 RPM and peak HP at 6000 RPM.
    Most engines with a 6000 RPM peak HP have a redline around 6500 to 7000 RPM.

    The manual does not list and HP or torque specs?

    i don't know about the valve floating thing...these are very high rev engines kind of like a motorcycle:) overhead cams type engines don't have the problems that the push rod V8's do...most push rod engine have a hydro lifter that runs on the cam to the push rods, this is where most of valve float comes from. the other cause is weak valve springs, but if you have weak valve springs, you would have had other problems by now. the lifter, in a high rpm setting, gets pumped up with oil and can't bleed down fast enough and hanges the valves open:( as far as i know these 660 engine are "cam & carrier" and are manually adjusted so just like having solid lifters like they put in drag cars so they can take the high rpm load.:D NOW i am not saying you should take your mini truck down the highway and see how fast it will go, this is just information. the newer trucks with electronic spark have rev limiters so the engine will stop you before you do damage. things to help keep your mini truck running good is to make sure your cam belt is good, and that your timimg is right...one more thing, low octane fuel will cause detonation:eek:
    hope this helps someone :D

    The Carry has the most modern engine that I work on. My daily driver is a 1971 MGB and it has a Crane fast street cam, ARP solid lifters and a flowed head. The engine has been bored to .040 over and blue printed/balanced. The head has dual uprated springs. I get valve float at about 7000 RPM.
    Every 4 cycle engine that I have operated will get valve float if over revved.

    The octane thing has been a topic for some time in the MG gear head world.
    Higher octane fuel burns slower and consequently produces more usable power in an engine that is designed for it. There is no value or increase in performance in burning premium in and engine that is designed to run on regular.
    The compression ratio on my MG is 9.8:1 and it runs fine on regular when operated around town with the ignition retarded 3 degrees. When operating on the highway in mountainous areas I advance the ignition back to the factory setting and burn premium.
    Remember that this engine was designed back in the 40s to operate on good old leaded premium. The distributor is the old kind with points and a capacitor.

    The best choice of fuel is the lowest grade that does not produce pinging when the engine is under load while operating in its; middle RPM range.

    you are right about the fuel, if you do not have a compression higher then 10:1, using premium gas is a waste of money unless you are pulling a trailer and running your engine hot. higher octain fuel is use to cool the engine in high compression or heavy load situations. you are right in saying that it does not help an engine that only need regular (if the engine is performing good) in fact it will make it worst. the engine will not reach proper engine temp causing poor performance and poor gas mileage. on the other hand if you have an engine that always runs a high temp (and you can find anything wrong) then use permium, it will run cooler. on your valve float you are having, do you loose power when you think your valves are floating? if so, you should stop reving that high, you will do engine damage:( and that would be a crime on a classic. check with the place you got your performance spring from and see if they got something better:D

    The highest RPM that I normaly shift at is 5500. The high RPM run was to see when float happened.

    On mine, the green wire gets attached to brown/white wire on the coil.

    On the newer gereration mini trucks with the EFI and coil over plug ignition the green tachometer signal pickup wire goes to one of the two wires from the cam position sensor on the rear of the cylinder head. Tom

    I run 6700 rpm all the time at 100Kms/h and I've run the little beast at 110 which means almost 7400 rpm. I've peaked at 118 once (8000 rpm) So it must be higher than 7000 RPM otherwise I'm running over redline all the time. 8000 must be closer to redline.

    thanks Little Foot

    Thanks for the info. I have a 2001 Suzuki Carry Da62T K6A eng. It has the
    coil over plugs. As I am hard of hearing and the engine is quiet I worry
    about over rpm in low range. With ATV Mud Lite tires. They make more
    noise than the engine on gravel or a hard surface. I have found Tachometers
    that will work thanks to this forum. Plug wire induction won't work. I really need
    to find a where a wire,and what color, to use for the tach pick up.

    Thanks

    What's up guys? I have a little bit older model truck compared to the ones yall have been talking about, but i though i'd post up in case anybody needed help with one like mine.

    I have a 92 Daihatsu Jumbo with the s83p motor. It's a carb'd 660.
    I used the Equus 6088 tach from O'riley http://www.oreillyauto.com/site/c/detail/EQU0/6088.oap?keyword=tachometer&pt=N0531&ppt=C0134. I ran the red wire to a key'd hot under my dash, the black to the same ground i used for my fog lights, the white to the hot wire going to the parking lights (so the tack lights up with the dash lights), and the green wire to the signal wire on the coil. The signal wire is the smaller wire going to the coil. Mine is red/black with silver dots on it.

    And i'm not sure how far yall are comfortable rapping your trucks out, but mine doesn't seem to like anything much over 5000. I ran it up to 6000 yesterday, and it was really screaming. Idk how you guys are getting yours up to 7500-8000??
