Down and out in 2008

[QUOTE=Sandeep;75850]Some more updates while I am waiting for the new fuel pump / regulator / filter.

The rear end is complete and on the ground



Very nice work. Question, I see a tab attached to the chassis snubber mount, it has made some scratches on your otter CV, what is it for?

Lastly, please keep us updated as to your choice of coil overs and how well they respond.

Saw that too. Figure it's a pickup/sensor for a speed input for the ECU. Sandeep, you have one on the other side too? Traction control?

That could be for the pick up sensor for ABS brakes I would guess,but ABS is also very hard to implement correctly i.e. mapping parameters in which it should operate.Much harder than motormanagement.Traction control would be very cool,but it is also hard to implement.

I have placed that tab on the other side too, and they are both for VR sensors.

The sensors pick up the heads of the cv bolts and pulse 6 times for every revolution of the wheel, so I know how fast the wheel is turning. I am programming an AVR microcontroller to interface to the S60Pro ECU and feed the data from the ECU, into innovate motorsports Logworks 3 data logging software. I have a bunch of other innovate stuff as well, so I am incorporating all of the data into a nice 7" TFT touch display on my dash

I can then log both rear wheel speeds, and compare that to the front wheel speed to see how much wheel spin I have when driving.

This will tell me if I need an LSD or not

BTW, the S60Pro has a traction control setting that uses the undriven wheel speed, gear setting and engine RPM to determine wheel slip and retards the ignition to keep traction

Lanner is machining my front hubs to use the 944 antilock rings that come stock on the hubs so I can play around with this feature.

Interested if you can make that work. Not sure what I am doing wrong, but still don't even see LUWS (left undriven wheel speed) and it's not the right hand wheel thats got the sensor

Yeah, it even lets you have a set max percentage wheel slip before it messes with timing.
Pretty cool all, but not sure if it works like that IRL if you have 400 RWHP on the dragstrip with street tires...

One more step closer to having a running engine this year

The 98mm JE's from LNE showed up along with the tool steel pins / rings and spiral locks
