Hello all, this is my first here joined because Brain is on this board and has tons of great information.

I've done some searching and I'm posting this just to verify that my information is correct.
To enable launch control on a 90-93,
1V on the connector board is connected to input 2 IN.
While input 2 out gets connect to PE1 on the mainboard.

Is this correct?

Took me about a year to get the ***** to solder my diypnp together and about 2 nights to actually do it.

Here pics before I soldered in the fuel pump stuff.

 

I use FLEX for launch in, you'll find you'll want to use PE1 for other things (like a/c in).


what is connected to the GND on the bottom left hand corner? (IIRC, those two GND ports dont actually go anywhere.)

 

thank you brain. i connected TPS SIG to that ground. i didn't realize that there was a closer one at the time.

 

Brain, you're awesome man sometimes your write ups are more informative than the diyautotune ones.



Loaded firmware on and calibrated coolant temp and IAT temp according to your charts.

There was a basetune for 460cc injectors I found, it was written in an older firmware than 3.1.0, is that okay to load on?
If so then I should be good to go?
