For an output source you could use a multimeter in volts mode.
For an output sink you could use a multimeter in diode mode.

Good stuff, glad you got it sorted.

I just got this pic minutes ago from the guy who initially built it. It shows the 90 degrees of separation. With MS, that wasn't an issue. I disagree. Instead of base timing at 10°btdc, it is 30 off puting it at 40°btdc. Tuneable range becomes 20°btdc to 90°btdc. What I'll need to do is remove and ...

jsa

10 degrees per tooth, so move the sensor to suit.

Is that pic with the engine sitting at TDC?

The EDIS module just fires coils in sequence A-B-C. Firing order 1-4-2-5-3-6; Coil A 1&5 Coil B 4&3 Coil C 2&6 Assumes; Edis pin 10 to Coil A Edis pin 11 to Coil B Edis pin 12 to Coil C Or has 11 & 12 been crossed to coil C & B? It'd be worth having one edis pin connected at a time to confirm which ...

Cylinder 6 - the one in the middle - I get intermittent strobing.

Cylinder 6, the middle cylinder or the middle coil??

Apparently some coil packs have pin 1 as 12v power and others are pin 4...something else to check out.

jsa

Sounds like MINPW needs to be set lower, has that been changed?

Has low slope been set to injector specs?

jsa

Pin 8 not connected is going to generate a fault code because it can't see a change when the pump starts. Wire it as per the ranger circuit. So you firing order is 1-4-2-5-3-6? It's wasted spark so 1&5, 4&3 and 2&6 always fire as pairs. You say 4&5 don't strobe the light. You should have lost 3&1 at...

jsa

Yes the fault code issue is strange, hence the suggestion to persue it further.

jsa

Above, I mentioned the impact of capacity difference on timing.

What crank angle is the CPS at?

What does a timing light show you?

Fault codes should be possible by jumper and LED, without a code reading tool.

Your ranger 2.3 to xr4 2.3 is the same capacity...same engine.

4007 is 1000V and the 4004 is 400V, I'd stick with the 1000V to be sure, to be sure, more safety margin. The 18V reverse biased zener may prove to be necessary, depends on what your tacho expects the signal to look like. Your tacho may already have a capacitor or zener internally to filter Vbat from...

Various versions of EDIS modules seem to be different with regard to IDM. Maybe EDM / IDM is more than just a naming difference. Some are 5V signal level while others are 12V level. You may need to split the EEC and tacho feeds from each other. Then use three 1000V diodes to combine a tacho signal f...

The EEC is expecting 4L of idle air, now 2.8's worth needed. Expect several tuning related issues to become apparent. Did you fit the 4.0 injectors or are the 2.8's exactly the same part? If you are talking about ballast resistor, then yes remove it. Might need to graft in the tach electronics from ...

That braid is called the screen. It's purpose is to protect the signals on the cables within from electrical interference noise. Yes it must be connected to ground, usually at one end. The better circuit diagrams will show it as a dashed circle or elipse around the wires. The EEC will count the numb...

Everything is editable in the firmware so long as a complete definition has been developed for the catchcode you have, or you are prepared to develop one . Along with a definition, associated hardware and software will be needed as well.

jsa

Pin 9 & 28 for DCL will make no difference.

jsa

While cranking, measure ac & dc voltage, frequency and duty cycle if you have those multimeter functions.

jsa

Search the keyword IDM or keywords IDM failure. I've not taken enough notice of octane adjust to be certain, but subtract a value across the board comes to mind. Fred Flinstone LOL, what sort of multimeter or oscilloscope does Fred have? Time to test signals at the EEC for IDM, PIP and SAW. Screechi...

Has Sailorbob said he won't update his definition for newer BE?

Just a follow-up after many many months since I first wrote up the document about the EEC Whisperer. . . It seems the automotive world got far more complex and modular than I realized. When I was thinking of the EEC Whisperer, I was still thinking in terms that there was a "central brain" of sorts ...

3 Speed Control (not needed) 3 Speedometer output (not needed - VSS will continue to input directly to instrument cluster) I said 3 was an input to the EEC, I said nothing about connecting it or not. 4 IDM (skip for now - can add circuit later - just sending IDM directly to tach as it was before) I...

jsa

Connect IDM, it's an EEC input.
VSS is an input too.

46 is the sensor common, never say never but I've never seen an EEC-IV with pin 44 as the sensor common. To be clear, it's NOT grounded to the vehicle chassis.

What fault codes do you get?

No PATS?

Having a dongle license and a software license on the same machine will cause issues like you describe. Apart from that, contact core or Clint.
