MSPNP2 and Innovate LC2 not getting along
 

Just installed mspnp2 and a innovate lc2 wideband with a db gauge and for whatever reason in tuner studio its hard pegged at 7.4 for the afr ratio. I wired in the yellow wire coming from the controller to the gauge and to the 21 port on the ms and have the settings in ts set for the reccomended corresponding voltage=afr outputs. The db gauge is reading appropriately it seems (maybe a little lean under part throttle low load) but TS is still hard pegged at 7.4. Tried following the input of switching the sensor type to lambada and also tried to follow diy's directions for setting it up but it didnt seem to really help any. Any hits?

You don't want to share an analog output with the gauge and ECU - run them on separate outputs and program the brown wire to give the same output curve using the LM Programer utility.

Matt, I had wired it like that to see what would happen and it had the same results as brown being calkbrated at 0v=7.35 and 5 v=22.35. Reads 7.5 on TS after programing lc2.

problem has been fixed thanks everyone

On another note what aftermarket tos would I have to get for the ecu to read an actual value. Mine just reads zero at all times. 1992 1.6

I assume you mean TPS. Do some searching on on 1.6 miata variable TPS. Something like the FM kit would be the easy button. https://www.flyinmiata.com/tps-upgrade.html

If you know someone with a 3d printer there are free plans for printing an adapter. Courtesy of a MT forum member. https://www.thingiverse.com/thing:2425389

I like the easy button and its coming from a reputable company too. What wiring changes need to be made to adapt it for megasquirt?

of course it was right in front of my face. Thanks!

How? Having a similar issue.
