MSPNP9093 with a 1.8 swap
 

I've installed the MSPNP9093 in my 92 with a 1.8 out of a 94.
Now I need to decide ...
Should I use the 1.6 base map, & modify it for the 1.8 or should I install the 94 base map & modify it.

Any suggestions on which is the easier route?

The engine is mostly stock & still has the MAF. I have a GM IAT ready to install, just haven't done it yet. Maybe I'll start there.

Install the GM IAT and use the 94-95 firmware so the idle settings will be correct for the 1.8 IAC valve.

the only change to make allowing the TPS to read.

The car's running with a 1.6 IAC, TB combo with the FM adapter plate.

So is it better to start with the 1.6 maps for the AFM, and IAC... then put in fuel/timing maps from the 1.8 base maps?

Dave,

Hey! you peeked under my hood! ;)

I guess that's the question I should have asked.. :noob:

i don't know if they're the same, but I posted up the settings for iac control for a 99 motor in a similar thread.
