Go pop the hood on your 3rd gen and look. Now go look at your first gen in the driveway. Done. <img src="/forums/images/graemlins/nana.gif" alt="" /> <img src="/forums/images/graemlins/lol.gif" alt="" /> <img src="/forums/images/graemlins/lol.gif" alt="" /> <img src="/forums/images/graemlins/lol.gif" alt="" /> Bill - you crack me up! Two points for you.

Thought I would post an update for posterity. The 10K ohm resistor mod illustrated here works just dandy on the I4 tach as well - but the tach reads about 33% high. No worries, this places the reading within the adjustment range of the tach. My tach now reads, and does so accurately. FWIW, this would also imply that there is no reason for those who want an SR5 cluster to limit themselves to the same cylinder count. Got an I4 but found a V6 cluster, or vice-versa? I'd bet you can adjust it. The easiest way is to temporarily remove the speedo, attach the harness to the cluster, and adjust the small white potentiometer on the circuit board of the tach. Oh, best to use a plastic TV tuner adjuster, you don't want to touch any wires/traces with the metal tip of a screwdriver. Second option, which is what I did, is to put shrink tube on your long small screwdriver and aim carefully.

For a long while, people were talking about super strange ways of making the Tach work. IIRC, even ORS hadn't figured it out yet (EDIT - not bagging ORS at all... just remember reading they didn't have a good solution). Something about the signals from the new engine being too different. Anyway, my question - what did you use to measure the tach for accuracy?

For accuracy, I used my wife's 97 idle speed... <img src="/forums/images/graemlins/zombie.gif" alt="" /> I'm pretty sure I am within a hundred, MAYbe two, RPM on the outside. Close enough for me. For that matter, I'd bet most Toy tachs aren't any closer. Redline sounds like redline, I would not want to take it higher. Nor would I need to. Even with the free flowing exhaust and intake, things start to fall off fairly quickly near there. Haven't run into the rev limiter yet, I think maybe that's 6 grand or so. <img src="/forums/images/graemlins/scared.gif" alt="" /> Not sure a 12 cylinder would still be within the tach's adjustment range.... <img src="/forums/images/graemlins/lol.gif" alt="" /> Besides, that would be a combo of a front and mid engine design I think. Where would you put the coffee? IIRC, even ORS hadn't figured it out yet (EDIT - not bagging ORS at all... just remember reading they didn't have a good solution). He just had never implemented it, he did know about it (though did not know if it applied to anything besides a V6 tach). Mike is very comfortable with mechanics and wiring (and it shows), less comfortable with eeety beeeety leeetle PCB traces and resistors. Probably tried it but it didn't survive the oxy acetylene very well. Lets all the magic smoke out that made the thing work. Very important to not let the magic smoke out.

When I did my 4.3, I hooked up another tach and adjusted until they read correctly. I like your idea better. LOL!

Here, the Chili has returned to propriety on our maintenance run on Argentine Pass. Hardly notice the peekaboo hood. By the way, yes, that is snow falling across the valley: ![[Linked Image]](http://home.earthlink.net/~noble.bh/sitebuildercontent/sitebuilderpictures/argtclnp.jpg) In other words, looks like before! She already has a 3.4 and she's not afraid to use it!

Yea I know IFS sux, but at least it's spent more time on the trail than at ORS this year. OUCH!!! In his SIGNATURE no less. Hey, with a weekend, some parts, ol' Miller Blue and a borrowed plasma cutter, we can solve that problem with a minimum of lost trail time. For your wife's 3.4 too... is it a good marital move to build her a truck that can kick your... um,... tailgate? Oh, by all means. By all means.
