Comunication problem with LC-1 and MSPnP
I have it configured as DIY instructions and configured the analog yellow (G3) to copy the brown that feeds the MS.

I am not getting any signal at the MSPnP it stays at 7.35

The G3 will bounce at KO and then stay down then bounce to 18 after a few seconds of the car running.

I have free cal'd it 4 times. Cleared by leaving it disconnected with the KO for over 5 seconds, cleared it with the LM programmer etc...

I dont know WTH I have not properly set.

I figured one of the systems would work (MS or the G3)

I have been dealing with this for 4 hours now.

Check the voltage on the wire to the MSPNP; what's it reading?

I am having the same issue I will check voltage and get back to you.

Eraser-X · **More MSPNP questions**

I was able to reset my LC-1 and what seems to have fixed my 1st issue. Now I am having a problem with the MSPNP running very rich megatune and the LC-1 are telling me 8 to 9 at idle and 10 to 11 on the road.

What firmware should be install on my 96-97 MegasquirtPNP, It looks like HR10d2 but the DIY autotune site shows HR10e?

Can I reflash it to HR10g and just load the base maps from DIY?

I know this is a lot of questions and please let me know if I should start a new thread.

It's 10E but I believe 10G would not be an issue if it is EasyThermed for your sensors. But it sounds like you just need to adjust the fuel a bit.

Thanks Matt,

I was able to get the correct firmware installed yesterday and to easytherm a copy of HR10g also. What versions of megatune display the correct firmware version in the top bar?

Also how come the AFR table from the MSPNP maps is full of super lean numbers? Does someone have one with some good numbers for a NA car to start with?

Now that I am getting things in the ballpark MLV is a great tool and I am getting closer to my goals very quickly now.

Thanks

It's quite simple to make your own, really. You want to be around 14.7 in most of the cells. In the 100 kPa row, go for about 13:1. Some folks think that you should also have a slightly richer mixture in the very high RPM cells, though I don't understand the reason for this.
