What I learned last weekend: the latest ECUs have a top speed limiter at 125 mph.
What you do, in a hurry- unplug the diff sensor.
I'm running a -524 ecu, because it was there, no chip.
When we switched from 225-50-15 to 225-45-15 RA1's
(there's a BIG circumference difference,on the order of 3")
we started getting into it at the end of the
front straight, at about 6000rpm.
At first, I thought it was a fuelling issue, but it was too consistent,
always right at 125, and it wouldn't do it in 4th, nor pulling hard up
out of t6, which usually shows up a fuel issue, too. After some trolling
around the paddock begging for help, and a bit of research(thanks, James) I bumped into
one other person who'd seen it (thanks, Chuck!) so we unplugged the diff.
And that fixed it. He said they had a problem with it even with a chip...
Things you know, things you think you know, and things you learn...
