Dallas: What's your plan for logging wheel speed? Are you going to get that from the ACD, or implement something more modern straight off of the wheel speed sensors?

AEM Infinity with speed sensors run straight into it (will tap into wires headed to the ACD). Unless something happens and I sudden become super baller for a Motec M130 to do everything in 1 system .

The end goal is to have speed sensors all run into the main ECU and thru CAN log the data in Racecapture. I can do a math channel and just calculate speed difference at front, center, and rear diff. Then I can pull that info into SoloStorm and I think display that during a run. So I'd have G forces, throttle, ACD Pressure (pressure sensor at the T-case), and diff slip %.

Since I feel like my suspension is pretty dang close to awesome, time to really sort out if the diffs are doing what they should or causing other issues.

I almost bought an M130 and the JRR firmware during their SEMA sale earlier this year. Entirely overkill for what I do, but I still want one.

How much was their sale price?

Ive been on the fence if I should do it or not cause I also want to ditch the OEM ACD computer. and you can get it all under control in the M130. The standalone motec ACD controller is like $1800 on its own.

M130 was $2000 and JRR knocked $100 off of their firmware. Still expensive, but they almost never do sales.

so dallas did you build some uprights for the rear? and thats what ur referring to thats transformed ur turn in majorly?

Dallas J

Yep and Yep.

The front fixed turn-in quite a bit and my car was pretty sharp with standard rear uprights. I was skeptical the rears would really be that big of a difference but first event, first turn was like WTF. Its hard to explain but you have to reset your expectation for how fast the front responds to inputs.

Dallas, what's your next car after the Evo? I feel like I need to align my next purchase with whatever you'll be modding next.

Haha, well if thats not the best kind of compliment..

so could u go rear billet uprights before fronts? sounds like it might end up being a bit unstable at high speed if its that pointy ?

Dallas J

While I havent tried that, I absolutely would fix the front first. Thats the most important part for sure. The rear puts a bow on the setup elevating it even further. But on its own, I dont know if that would work well or disastrously. My instinct says it will just pronounce the tripod harder. We want to lift the inside rear a little, but it shouldn't be more than a couple inches.

yea the uprights look amazing. i dont think i could afford, and i'm still not totally sure it's legal for gridlife's street class, let alone a few of the more restrictive classing for TA that i've been looking at
