2: Download and install EasyTherm.
3: Unpack the code to a location on your hard drive. For illustrative purposes, we'll say that it's in \Desktop\msns-extra-hr_10g_m\
4: Fire up EasyTherm.
- In the first field, give it the location where you put the code, ie: \Desktop\msns-extra-hr_10g_m\
- Under "Coolant Temp" and "Intake Air Temp" tell it what kind of sensors you have.
- Under "Apply", tel lit "Write .inc and .s19 Files"
- DISCONNECT YOUR IGNITION COILS OR IGNITER
- Power up the car, connect the serial cable, hit "Test Port"
- If successful, hit "Download to Megasquirt"
- Wait. This takes a while.
- When finished, close EasyTherm.
5: Power off the MS. Load Megatune.
6: Power on the MS. In Megatune, load the MSQ you saved earlier, and flash it to the MS.
7: Power off the MS. Re-connect your ignition.
8: Start the car.

i dont want to have to use Easy therm to install it because i am using ford senors for IAT and Coolant and i have bias resistors in place in the ms so that they read properly and dont want to mess that up.
If just use the stock gm values will that mess up my coolant and iat readings. because if does work that way i will give it a shot this week.
are there any settings that need to be adjusted to get your code to work other an just flash the MS?

I may have already modified the firmware w/ the miata values... I can't remember. Just use easytherm and use whatever the proper values are for your setup.
Nothing else to change in megatune other than the fast idle speed, if you want. The only thing you need to do other than flash the MS is wire up the circuit.
Run either the A/C input (1Q) or the blower input (1S) to JS4. Those are 0-12v, but JS4 wants 0-5v. So you need a voltage divider or diode clamp to keep it within range.

I'd like to try out your modified code tonight. I just need to figure out which wire is JS4 on my MSPNP's extra-feature connector. I'm probably going to just wire it to ground via a switch temporarily just to see how it works before I do a more permanent install. One question, do I need to have the IAC set to closed loop mode? Or can I leave it set to warm-up mode only? Cant wait to try this.

Maybe a moderator should split this thread? Most of the conversation has had absolutely nothing to do with the thread's title "Purge Valve Solenoid", which I will take the blame for 
.
Or I can just create a new thread....

Are you using closed-loop idle? Has the car warmed up? Are you grounding it to a wire that goes to the block?
Open up the Analog input gauges in Megatune/TunerStudio and tell me what you see.
