Basic data needed (PW, input type etc)
Looking to set up a stand alone ecm for a 91 1.6 liter. Need the following basic info:
ISCV Pulse width Frequency and duty cycle range Power steering switch input (+12v or float to ground?) A/C compressor switch input (+12v or float to ground?) Clutch switch, looks like a float to ground, but is it supposed to raise or lower the idle when grounded? Using stock 1.6 injectors. at 8PSI, what % duty cycle are the injectors running, or do I need to go bigger (system will never run morre than 10PSI boost). THANKS! |
Search much?
|
Under ISCV I only find my own posts
|
Probably because most people have been calling it an IAC - different terminology. If your standalone is a MS, you'll find the IAC settings in the MSQ file for the MSPNP.
|
Thanks. From the FSM saw the IAC as a temp controlled bypass, while the ISVC is ECM controlled. I have a DIY ECM, not a MS, so I am starting from scratch. Will search under IAC, Thanks.
So people have complaints mostly they can't run their A/C properly? And no CEL so they can't pass inspections? Any other major issues for daily drivers? I'd like to try my hand at a fix for each. |

download the msq file from the mspnp website for your engine and take it from there.
http://www.megasquirtpnp.com/models/...with%20AFM.msq And here's a 1.6L pinout which should hopefully answer your other questions: How about posting some info on your DIY ECM? Sounds interesting. Maybe a few pictures. |

Thanks again. Here is the unit. Built inside the stock box. |

and here are a few pics of the car build.

wow, impressive. is the ECM a commercially available product? doesnt look like a prototype at all.
|
Potentially this will be available soon, IF I can get all the accessories and the code flash to work correctly. If not, then perhaps as a "for off-road use only" item.
|
Did you build that one yourself? If not, then who did?
|
My company builds these units for CNG powered heavy duty vehicles (buses, trucks etc). I'm just playing with this unit to see if we can get a decent result for the Miata track car. If so, I'll make some available real cheap for those willing to share their files with me!

I assume based on another post that this is one of the OmniTek EM series.
This line on your web page blew my little Megasquirt world away: "The Omnitek EMS offers self diagnostic capabilities (OBD)" Now if you could output OBDII codes... Is this a new model? EC44-M maybe? BTW, it's nice to have someone w/ your racing back ground on the board. Welcome. |
This is actually an EC66, capable of driving a 6 cylinder. The EC44 runs this little beauty on E85
http://www.blogsmithmedia.com/www.au...uncup2_opt.jpg read a bit more about it here..http://www.autoblog.com/2008/02/25/b...h-the-fun-cup/ I am working on the OBD II outputs..... |
Oh and thanks for the Welcome!
