Clewett Engineering..... I had the Chris White to get me out of the hole for a bit and it only made it WAY worse....

Looks top notch! What issues were you having with the previous setup?

reno808

chris white setup. the 60-2 tooth wheel is not even true. and what ever you do DO NOT adj the alt belt.

I kept getting trig errors.

Did you get trigger errors with the stock speed/ref sensors too?

reno808

I started to get triggers errors with the stock speed/ref sensors as i was pushing the car on the dyno. I was spending more time adj the filters for the speed/ref senors. This is the reason why i went with the 60-2 setup. With the CW setup i started to have issues at high RPM because the wheel wobbled due the the wheel not being true. then i was having even more issues when i had to leave the car outside and the wheel started to develop rust.

Sounds like the problems I've had with 60-2 crank mounted triggers on my Audi. I even had the wheel trued to a crazy degree and still had problems. Moving to a flywheel 60-2 trigger.

Did you ever scope out the actual sensor to see the waveform stability? And measure peak-peak voltages?

reno808

The flywheel 60-2 would be great, but i missed out on that option due to low car funds.

Yes as matter of fact we test 3 sensors all very close to specs.

Hope the Clewett piece works!

Even after true'ing on a lathe, this was the best waveform I could get with a crank trigger wheel. There's still vibration of the crank and mounting points that'll cause variation.



Looking at the CW setup, it's not surprising it didn't work well. That's not a very secure place to put it.
Gap is also critical. Most like gap of 0.025" or less. Also some sensors don't have a perfect symmetrical polar pickup pattern, so sometimes it helps to try rotating the sensor (all while maintaining the correct gap).

Albert is using that setup on his builds, he says it is very reliable.

Whose ECU are you using? I am using the cam gear for my ref and sync.

Thats a Link G4

Could you run an S2 or 968 Flywheel?

Patrick Motorsports makes a 60-2 fly. I think Rich Luciano bought one from memory. Looks like reasonable costs vs alternatives. http://www.patrickmotorsports.com/

What ecu and trigger sensor are you using? I had no trouble with the Chris white 60-2 set up.
