Scott M A "stiff" pedal and the car not slowing is the ABS or "ice mode." Try to let the car settle before pounching on the brakes and stay out of the bumps in the braking zone. A soft pedal would be pad or fluid fade.

I actually took the aggressive pads out, and changed to street pads. I have the Ferodo DS2500 in front, stock pads rear. Have an HPDE at thompson with the LOG 39 guys tomorrow, so I can report back if problem happens in the same spots.

kfennell Maybe you have a vacuum leak? The pedal is vacuum assisted.

Could always pull the abs fuse as well for diagnosis.

Someone actually caught the start of the flooding. This is the track...

Now just a little over a month later they've cleaned up the track completely (parts of the track that weren't ripped up were buried in over a foot of fine silt) have the area graded and ready for repaving.
So I was absolutely estatic that it was open even if we were using the go kart infield track to bypass the section that was washed away.




And a lap of the track When a lotus feels like a bus, you're on a tight track:

Car ran well, needs more front end grip, but I can place the weight on the rear even under full acceleration and it just sticks. So brake late apex late and keep the weight on the rear and theres just endless grip.
I was getting a very stiff pedal on the same spot in the track and I thought again I was fading the pads. (I had this happen once too at Thompson last weekend at the end of the 120+mph straight and almost overshot the corner).
But on the very next corner the car would brake fine. I kept getting a stiff pedal on the same braking zone, and I would have continued to think it was pad fade until I actually "broke through" the stiff pedal which revealed more travel and much more braking force. So now I'm wondering if I'm dealing with the dreaded "ICE mode".
If so, even under ICE mode, the car was still braking pretty darn well, and I only got this sensation consistently in 1 braking zone (after the hairpin) headed at the cones downshifting to 2nd. @kfennell what do you think?

Ls1Rx7 Good news is that I can confirm the A052s have super progressive breakaway. So far i like them more than the R888Rs (and much quieter) even though I'm not seeing a ton more max lateral grip

Prob true, but it was sliding almost immediately, i think I was just too quick with the wheel. Lots of room for improvement on this track, it was my first time there and as you can tell the track is narrow with little runoff in multiple spots

Ls1Rx7 Finally got it out on track,
First time to this track, but had a good time. Actually had a couple "moments" on the track and luckily found my biggest on on video from a car chasing behind. He seemed more enthusiastic about it then I was Lol. Is that a "bug-aboo" chant?

And From in the car (not soo much drama) The A052s are pretty progressive during breakaway but I'm not honestly sure what caused this slide so I just let the cars behind me pass and let the tires cool off a bit.

FYI: this is the norm for transistor-switched circuits. It's much more common to switch the ground side of the load instead of the hot side.

The times that the injectors went haywire don't really make sense though, with that theory (mainly while puttering along in traffic). Also 3 of the 4 plugs were totally fouled. The 4th was fine, so I'm still not sure it would be a grounding issue, but I'll throw some electrical tape around the pigtails regardless.

I'm going to send the injectors out to get cleaned, and I'll pull the plugs again after a couple hundred miles and see where we stand. Also it makes sense for injectors to stick seeing as they sat for 9 months.

Just a simple bolt on.
Gave the car much more of the "Atomic Flee" look in people's rearview

To be honest, that's what you should name this thread.

Or your car.

Partsfinder Looks great. Glad you were able to finish your rally. My first event with rebuilt car this week. Fingers crossed.

Of course I couldn't find anyone in the paddock with a real scanner so I don't know what the computer was seeing.
