Gen 2 Innovate Motorsports LM-2 WBO2 Install

[DLF]

I have found that the ODB-II RPM and MAF voltage using the OBD-II Innovate Motorsports cable (p/n 3809) is VERY unreliable.

So, I decided to use the analog cable (p/n 3811) to get what I needed.

I had read that in order to get a tach signal from a Gen 2 that you need a tach adapter.

Well, not so fast.

I tried the #1 ignition coil signal from the PCM, but that didn't work.

What does work, however, is connecting the LM-2 analog RPM input to the #1 injector signal from the PCM.

On my PCM (BTC0), the #1 injector signal is a tan wire (#75) and the MAF voltage is a LB/R wire (#88). I connected the grounds for both inputs to a BK/W ground (#24).

I did that on a friends 2000 GT for a NOS kit. Works well and reads right.

That trick only works on sequential systems...

And the result from my latest tuning session. There's a nice road just a couple of miles from my house where I can make full throttle blasts.

looks great..
you shooting for 13?

 

[DLF]

Decided to try 12.7 actually, got pretty close.

I know what it'll run @ 13, thought I'd see what a little richer A/F would do.
