LM-1 Install Questions - SRT Forums

Hey All,

I'm installing a LM-1 Wide Band and have a couple of questions:

1. Can I run a wire off of the coil harness (where I had the MSD Tach p/u) and place it on the RPM terminal on the cable? If not what method did you use? I do not have the inductive p/u for the #1 spark plug wire.

2. What scale do I use to convert MAP voltage to convert to Boost for the PSI/BAR readings. ex: .75 = 0 psi and 4.95 = 18 psi (Stage 1 Car BTW)

3. What is a good source for IAT, Intake? Up Pipe? What wire? Any voltage conversion needed?

4. Ditto for TPS.

Thanks in advance.

PS - When I get this all the way done I'll post some displays. I already did some passes on the hi-way with AFR and played them back on my PC. Very Cool!

At 17 psi I had a 11.2 AFR at redline. STG 1, 3" DP, TCC WGA.

Thanks, but I'm looking for SRT specific information.
