Do you guys have any ideas???

moponys · 10-16-2003, 12:11 AM

I've recently changed from 3.73s to 4.10 and on the same day of doing the gear swap I added a Hi6 ignition. Ever since my car can't go past about 5700rpms on my stock tach.

I've replaced the stock speedo gear with a 23 tooth and have had the rev limiter removed by getting it custom tuned on a dyno.

I was fine before the 4.10s and the ingition. My car also has a 3000 stall converter so goes through the rpms pretty fast.

Do any of you guys have any ideas???

Thanks,

Tony

What did you set the rotory dials on the end of the hi6 to? You did set them, didn't you? The first one is thousands and the second is hundreds

Thanks for your reply...

I just found the rotary dials and set them to 7 and 0...

I had a shop near my work install the Hi6. Prior to setting them to 7 and 0 they were at 2 and 0.

7 and 0 should yield 7000 rpms right???

Thanks,

Tony

Thats what the instructions say. I have mine set for 6000 but my engine is pretty much stock so it ususally doesn't even see over 5200 (only when Iforget to shift )

Thanks for the help Bill...

For this to work do you need the "Optional Switch for Retard, Anti-Theft or stage Limit" switch that connects to the yellow/white wire???

I test drove it tonight and setting the dials didn't help any. Even when I put them to zeros, it still couldn't get past approx. 5400rpms...

Do you guys have any other ideas.

Could it possibly be a weak or bad battery or coil???

Since I put the 4.10s on the same day, could it be that I need to have my auto logic chip re tuned for that gear ratio??? it wasn't a problem when I had the 3.73s...
