What wire to tap for RPM monitoring?

[NoDestiny]

I have a Zeitronix wideband setup that I want to hook up in ye ol minivan. 2.5L turbo of course. Anywho, what wire should I splice into in order to get it recording to my wideband? Worked well in my neon, hope to get it going soon on the caravan!

- coil should get your signal

Oh yea it might have to be programmed in to the zeitronx how many cylinders and all that but you probobly already know that since your logging rpm.
I dont think it shows rpm on the screen does it ?

[NoDestiny]

Yeah, it can show...
AFR
Lambda
Boost
RPM
Throttle position
EGT
Voltage
and I think 1 more - custom user setting.

Its all through a laptop though.

What wire exactly would I tap into though?

[NoDestiny]

Sorry to be a pest, but I would like to hook this up and datalog more accurately than I am not (JUST doing AFR right now )... anybody?

RPM I had to tap into the RPM signal to the guages because i was having problems with using hte coil ground. Bansheenut uses the coil ground on his R/T.

Boost and EGT require owning the EGT and boost gauge they sell.

AFR is pretty useless without RPM. Boost datalogging helps too.
