My tach seems to run fine when i'm being easy on the car as in shifting at 3,000 rpm, and not really running it. However, i jump on it one time and run the car like i do when i race and after i ease back down on the car, the tach will climb like normal until 2500-2600 and then it jumps up to 4250 and stays there until i actually reach that engine speed....its not so much a problem, it just gets really annoying. I thought about the possibility of a new cable but it runs fine when i dont really try to push it. any suggestions?

 

That doesn't sound like crack to me. This is a tach on crack!:

 

I don't think there's a cable that runs the tach. I'm sure it's all electronic, so I'm thinking there may be a grounding problem somewhere in your cluster, perhaps.

 

I wish I could take my tach to 8,000 but then i'd really screw my F22. i'll have to check that out and see if there is a bad ground.

 

well i hope to increase my rev range to 7500, just need to install that damn oil cooler and do a small re-build

SO the tach reads off the ignighter? I wonder why Prelude tachs are so far off.
