NEW 82-89 & 90-92 Tachometer Circuit boards - Tach Fix
Direct fit and brand new. Tachometer circuit boards for 82-89 and 90-92 Camaro tachometers. Please let me know if it's for a V6 or V8. I hand build each one and calibrate it on my bench. All are made with high quality, American made components. There is a potentiometer for fine adjustment if needed. LIFETIME warranty on the circuit boards.
Circuit boards with LEDs are now available! Make sure you are getting a power and coil signal to the tach with these diagnostic led lights.
$45 for basic boards, $55 for boards with LEDs.
I cover shipping to continental US. Please let me know if you have any questions.
I've done a lot of work on my car, but I haven't tackled (pun) the tach.
Mine reads about 5800 rpms at all times.
Even with the battery out of the car.
It never moves.
Do you think I could install one of your new boards, and revive it?
Could we get a wee tutorial on how to complete the job?
Spring-compressors, and the full weight of the car hanging over me on $16 jack stands doesn't faze me. I get a little quivver in my belly when I get near electronics.
Stupid question...my tach in my '88 5.7 TPI works, but reads several hundred RPM too high, and it gets worse the higher up you rev the car.
Would this correct the problem, and is it an easy job to swap the board?
Absolutely. That is the most common problem I see with these cars. I pre-calibrate my circuit boards, but if it's a little off, there is the ability to adjust it. Once you pull your tachometer out of your car, just unbolt the old circuit board, move your mounting bolts over and install the new one.

That's a little trickier question. My circuit board may fix it if the problem is the main IC, which I suspect. But more rarely is the case where the air core meter is bad. (the thing that spins the needle). In this case, my circuit board would probably not fix it. I have only come accross 2 tachometers that a meter was bad. So odds are that it will fix it and if it doesn't, I'll be happy to refund your money.
- If you need me to walk you through it, just give me a call.
Just curious, do you perform a similar service for the speedo circuit board? The speedo in my '92 T/A has a little bounce in it (particularly around 50-60 mph). It seems to read about 10% too high as well. I use those radar advisory boards (?) and if my speedo says 27, the radar says 30. At higher speeds it stays at about 10% off of what the radar says. Additionally, if I press the trip odo to reset it, the odometer won't work for a few miles. Even then, I don't think it counts correctly. I replaced the VSS and it still has the same issue.
Unfortunately not. The tachometer circuit board is completely independent of the speedometer. I believe there is a thread on here about fixing that problem though.
I have read and followed the speedo thread. Unfortunately, that one deals with the mechanical gears. I checked mine and they are in good working order without any of the wearing or broken pieces that are commonly found. Kind of perplexing and aggravating.
unfortunately not. I only have circuit boards for camaros right now. Do you have a pic of a trans am circuit board? I would be willing to look at it and see if it is something i can reproduce.
Thanks, Greg
im running the factory tach off of a full MSD ignition system with the 6al box. tach output comes from the box itself, but the tach is still reading lighter than it should be. is this board ok to run with the MSD box, and will it allow me to fine tune?
damn sorry man Its been so long I forgot, I ordered one from another place after seeing the ones on ebay for even more than this other vendor , hate it cause this is a good price .

I have a spare speedo sitting in the garage, would you be interested in me sending that one to you to use as an example?
I'm about to install a T56 in my '88 IROC, which means I'll be pulling the cluster in order to accommodate the "magic box" that will convert the VSS signal from the transmission to a cable drive for the speedometer.
Sounds like a good time to install one of your tachometer boards. Do you still have them available for an '88 IROC-Z?
If you like, PM me...I'd be interested in purchasing one in the next few days.
Any update if you'll offer one for the Firebirds? I have a spare tach that I can send. I don't need it back.
sorry. I just saw this. I would absolutely be interested in trying to make a replacement. Please PM me your address, and we can work out shipping details.
Hey greg… just your order from Ebay… didn't know you had a TGO account. GREAT GREAT PRODUCT SIR!
worked right out of the box and I would suggest Cajun tach shop to ANYONE with a third gen.
tach works perfect now after years of wondering what RPM I was at. I would shut down at 3K thinking I was 4-4500 on dial... turns out I had been shortening my throws waaay too much. now im 100% confident in my shifting.
if you have been waiting this tach board, I HIGHLY suggest Greg here
Whats the word on Firebird/TA tachs? My '86 tach works when it wants to. Sometimes works fine. Sometimes slowly comes up to idle but doesn't react to revs. Other times doesn't even move. Running MSD Ignition if that changes anything.

I can't say that i've heard of that problem before. They usually just fail completely or max out. This is of course with camaro tachometers. I only have one firebird tach chip for sale right now, and that is for 82-84ish cars. maybe you can send me some pics of the circuit board on the tach and maybe i can repair it?
Around what age or mileage does the tach board usually fail?
I've seen NOS tachs not working right out of the box. Never used. and i've seen some in clusters with over 200k on the odometer. it's really more of an age thing i guess...
do you still have one for an 88 IROC with a 305? Also, how much does it take to install? I noticed in an earlier post you mentioned moving the posts, do i have to relocate them? or will it just plug in

I have a few ready to go. If you can pull the Tach, it’s simple to replace the circuit board on an 88.
Free bump for you. I ordered a tach circuit board from you off eBay for my 89 IROC. It was a perfect fit and it fixed the tach. Before, it would peg at 7000 rpm anytime the engine was running. After the install, I used my old Tech 1 and compared the two rpms and it was dead on at multiple points on the gauge. Awesome product! So nice to have a working tach again.
