ECM Enabler. Running a G1 Insight with no IMA.

Well, I originally made a mistake but it's corrected now. J stands for jumper, I believe. It's what you're wiring into. Probably looks something like this:

I just built the circuit but there appears to be a problem. Pin 6 in J-1 (motstb out) isn't connected to anything.

I plugged in the programmer to see if it would recognize the pic, it didn't. Of course the circuit wasn't connected to the car yet.

I'm tempted to say, connect it to Pin 4 of J2 (also MOTSTB). But I'm not sure. Can we have a picture?

Ecm enabler is installed and ready to be programmed. Pic programmer recognizes the pic. Just have to find suitable 12volt power and ground lines from the MCM harness, and download Peters code into it.



Quick note: All 3 MOTSTB should be connected together in the diagram in the previous posts on page 3.

If successful, this would delete both BCM and MCM computers, and IMA battery. My one worry for the time being, is if the 12volt battery will charge properly. From my understanding the MCM is integral to running the MDM which feeds power into the DC-DC which charges the 12volt. All current IMA bypasses have so far left the MCM connected.

The Eagle has landed!!! Ecm enabler is up and running, no IMA or CEL codes on the dash. Ima battery, mcm, bcm have successfully been deleted. This is now a 100% internal combustion engine Honda Insight, "batteries-not-included."

There are 3 giveaways that the Ecm Enabler is present. 1, CEL turns off after 1 second when dash is lit to secondary key position. It should stay lit for about 15 seconds and turn off to show emmissions system is ready, or if the 12 volt was just disconnected it should blink a couple times to indicate it is not ready. 2, When you short the obdII with a paper clip to read blink codes, the CEL stays lit, but does not blink to indicate any codes. 3, Battery gauge is empty, will not assist or regen.

This is a momentous occasion! I haven't driven it yet, tomorrow i'll register her and see if she passes Inspection! Would anybody like to temporarily loan me an OBDIIC&C Gauge to test for leanburn among other things and document how the Ecm Enabler affects the car? I live in Pittsfield MA, USA. I'd be willing to put down a refundable deposit for it's return.

Notes: Peter sent me two versions of the code, the correct version appears to be "ECMFooler12F1822_080215.HEX" at 2.26kb vs "100215" at 2.44kb. Version "100215" turned off the IMA light but gave me CEL 69 and 36; basically saying MCM could not be communicated with (unplugged).

Congrats i'm excited to hear if it passes.

Glad you have it in and working, looking forward to the results.

The real deal will be if you pass inspection. If you do, this will be a great advance in the right direction. If not, we'll then that's going to suck.

Bad news first: There's a problem. After about 11 miles of driving the CEL comes on with blink code 69. CEL stays on, IMA light stays off. At that point the engine stops behaving smoothly. It's like it loses a little power or there's hesitation between throttle application. Uncertain, but the brake light on the dash could be related. It came on momentarily when i lugged the engine (stalled, or to high a gear), or i believe when i revved about 3k-rpm out of gear. Currently brake light is on, will not turn off. Brake light does not flash a blink code. Momentarily goes off while obdII is shorted to give blink codes. Battery dash light has never come on so far.

I was driving it well during the 3rd attempt at 11 or so miles. It came on at a nice steady cruising speed.

I don't know the sub code, but CEL blink code 69 refers to either (P1600, P1601, P1644 and P1645). All related to the MCM which the Ecm Enabler replaces in the car.

Good news: Durring the time the ECM Enabler functions, LEANBURN WORKS!!!

From an even throttle position at steady speed on constant grade, the mpg gauge will suddenly move up 25-30mpg. Like wise on occasion it'll suddenly dive to around 50-65mpg from 90-100mpg. Steady state mpg can be much higher than is possible for the speed and throttle position; likewise it can have more engine power than should be possible at a given mpg reading. In addition i can feel the car regularly go in and out of leanburn, it feels like mass gets added or dumped from the engine load. From my own experience driving a non-lb CVT and a MT with lb disabled from ima and cel lights: 100% it Leanburns!
