Hi Justin did you ever finish that code?

Yeah, some code is posted a few threads earlier. I don't know whether anybody else has tested it yet (other than me). Please do and let me know if it works for you!

1: Connect to your MS with MegaTune, and save a backup MSQ of your tune to your hard drive.

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.
  1. In the first field, give it the location where you put the code, ie: \Desktop\msns-extra-hr_10g_m\
  2. Under "Coolant Temp" and "Intake Air Temp" tell it what kind of sensors you have.
  3. Under "Apply", tel lit "Write .inc and .s19 Files"
  4. DISCONNECT YOUR IGNITION COILS OR IGNITER
  5. Power up the car, connect the serial cable, hit "Test Port"
  6. If successful, hit "Download to Megasquirt"
  7. Wait. This takes a while.
  8. 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.

why do i have to use easy therm? the car i am using this on is a 92 mustang and for my coolant and IAT sensors i have put in the proper resistors so that MT reads the proper way. since that is the case do i have to still use easy therm?

92notch, did you ever get to download the new code? Anything to report back?

ckkcmx5, exactly what kind of delay circuit did you rig up? Care to share.

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.

Glad somebody's finally going to try it! I'll have to go back and look at the code. I didn't test it in warm-up mode, just closed loop.

All the cool kids get MS-III and use the a/c idle up function like me.

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....

Ok, It doesn't seem to be doing anything. I'm grounding JS4 and expecting the Idle DC% to go up. Nothing seems to happen.

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.

Yep the engine is fully warmed up and in closed loop mode. I've got good, verified ground. Where do you find analog input gauges? I'm using tunerstudio.
