Raise rev limit with D-cal?

[mock_glh]

I'm running an '87 Stage II MP (641) LM in my Omni. I'd like to raise the rev limit to 7200 RPM using D-cal or CHEM. Which table would this be on the list? I would be creating a new chip for this.:confused:

Thats not going to be a table, its going to be 2 16 bit constants.

From what I have found, there are 3 main rev limiters. One for bad MAP, one for bad TPS, and the main fuel cutoff.

C567 1300 = 6167 RPM Fuel on
C569 119F = 6650 RPM Fuel off

As you notice, the hex goes down, as to the increase in distributor speed, and the distributor window.

I would change them to this.

117D
1000

That should turn the fuel back on at about 6500 and turn the fuel off at about 7200 or so.

Of course, you can play with those numbers and do whatever you want.

OK, I'll try that. Thanks a lot.:thumb:

Why don't these addresses show up on the files that I have (87_Turbo2_MP.bin and others)? I've seen C567 on one but it doesn't show any data. Do I have to scan my existing chip to see them?

[mw6886]

They probably aren't goint to show up in a table file anywhere, at least not that I have seen.

You'll need to add those the your table file, as 16 bit constants.

Even if you scan your chip, they will not show up. Most of the constants will not show up, as there are over 150 constants - best guess.

Yep, most constants don't show up in the scan. They don't have a recognizable data structure like the tables do.

OK, I have the table file and everything looks good. The scale seems to be inverted and the numbers on the bar are nowhere near the RPM's they represent. Is there a set of min and max numbers I can apply to the scale so I can see what my settings really are? What about the "Chrysler name" for the tables? I just made them up. Will that work or do they have to be something specific?
